GHD | Report for SA Power Networks - Safety, Reliability, Maintenance and Technical Management Plan, 33/17465 | i

Executive Summary The Safety, Reliability, Maintenance and Technical Management Plan (SRMTMP) is a document that details the management framework used by SA Power Networks to ensure that the network is operated and maintained in a safe and effective manner. This is supported by a number of manuals covering policies, strategies, operating processes and standards.

This audit report has been prepared following interviews with key SA Power Network’s staff in March 2014, and addresses the following:

A review of general company compliance to ensure SA Power Networks’ general approach in relation to compliance with SRMTMP obligations;

A follow up review to the April 2013 general compliance audit findings; and

A review of all of the current individual manuals for currency, accessibility, availability etc. and in particular whether the recommendations from the 2013 audit have been addressed.

The scope of work was designed to provide assurance that adequate and effective processes have been established which demonstrate SA Power Networks compliance with the latest Safety, Reliability, Maintenance and Technical Management Plan.

As with previous reviews, the methodology involved the interview of key staff responsible for the “ownership” of each of the manuals and standards referred to above, and the interview of a sample of those staff whose operations were directly impacted by the policies, procedures and standards referred to. The key staff interviewed by GHD was nominated by SA Power Networks.

The following is a list of the key findings and recommendations:

1. Compliance with the General Audit Requirements

It was found that issues identified in the 2013 review (mainly minor) have been either attended to or are being progressed.

Areas of compliance from previous audits were generally found to be satisfactory and some additional findings have been referenced. As with previous reviews, this is not necessarily a major issue however, because the majority of the recommendations are directed at procedural improvements that can be undertaken in the longer term.

The previously identified inspection backlog continues to be addressed with MBFRA’s targeted for completion by the end of 2014. NBFRA’s are targeted for completion by 2018. This increased inspection regime has however resulted in an increase in the number of defects being identified, which will require either a change in the defect management strategy or an increase in funding in the next Reset to ensure that they are adequately managed. We understand that SA Power Networks will be discussing the defect management strategy with the OTR to achieve agreement and will be seeking appropriate funding to complete the inspections and the identified defects in the next regulatory period.

Accessibility to information contained on the Intranet has seen continual improvement, with documents and manuals being located in a more “user friendly” system. All personnel interviewed were able to navigate easily through the Intranet and locate the manuals, procedures, directives, policy documents and the like where referenced within the manuals of the SRMTMP.

Roles and responsibilities seem well understood, and all staff interviewed were familiar with their job descriptions and able to refer to other documents that place requirements on them.

GHD | Report for SA Power Networks - Safety, Reliability, Maintenance and Technical Management Plan, 33/17465 | ii

The introduction of new, nationally harmonised WHS legislation on 1 January 2013 necessitated an update of business documentation and practices to ensure that the business meets its obligations under this new legislation. On the whole it appears that SA Power Networks have changed the majority of their documentation and practices, with only exceptions in instances such as minor WHS acronym referencing and the like. These are not considered material and are to be updated at the time of the next manual cyclic review.

Staff interviewed highlighted a number of improvements that have occurred over the last 12- 24 months.

2 Findings on Previous Recommendations

There are a number of recommendations that are the same as previous year’s recommendations, with some recommendations going back more than several years. These are either considered to be a work in progress, or have been identified by SA Power Networks as a lower priority item.

3 Review of Individual Manuals

The SRMTMP manual reviewed for this audit was the August 2013 issue.

There has been some significant improvements and updating of manuals over the last few years for a number of reasons, including:

Preparation for the 2015 – 2020 Network Distribution Determination (reset);

The changing regulatory environment such as the nationally harmonised WHS legislation;

Risk reduction;

Greater emphasis on either simplifying or clarifying instructions and procedures; and

The rollout of the NBN.

The reset preparation in 2013 and 2014 has seen significant works on the review and updating of a number of manuals including

Manual 12 (Network Maintenance Manual); and

Manual 15 (Asset Management Plan) and the suite of category AMP’s that sit under M15.

As the reset preparation is ongoing at the time of this audit, the changes were incomplete.

There are a few manuals (28 and 29) that are being progressively phasing out.

4 Review of Specific Areas Requested by the Office of the Technical Regulator (OTR)

The OTR did not request any additional review for the 2014 audit.

Conclusions

Overall it is considered that adequate and effective processes have been established that demonstrate SA Power Networks compliance with the SRMTMP and that the organisation has embraced the principles outlined in this and previous audits.

The majority of the issues raised are considered minor, are procedural in nature and are considered to be a work in progress. While a number of issues appear to be occurring from year to year, they are considered to be minor in nature. Explanations for reasons are contained within the body of this report. Many of these are progressing or will be progressed in the coming years.

The inspection backlog continues to be addressed with MBFRA’s targeted for completion by the end of 2014. We understand that SA Power Networks will be discussing the defect management

GHD | Report for SA Power Networks - Safety, Reliability, Maintenance and Technical Management Plan, 33/17465 | iii

strategy with the OTR to achieve agreement and will be seeking appropriate funding to complete the inspections and the identified defects in the next regulatory period.

There have been a number of other practices and procedural improvements driven by changes in the regulatory environment, improvement in safety practices or general procedural improvements. It would appear these changes have been adopted as part of standard business practices.

The preparation for the 2015-2020 reset is resulting in some significant changes to some of the manuals and SA Power Network practices. The majority of these are in the areas of strategic asset and maintenance management. The manuals and associated strategies and practices are still under review and will feed into the reset submission.

GHD | Report for SA Power Networks - Safety, Reliability, Maintenance and Technical Management Plan, 33/17465 | 1

1. Introduction SA Power Networks Safety, Reliability, Maintenance and Technical Management Plan (SRMTMP) comprises a number of “manuals” that detail the management framework used by the organisation to ensure that the network is operated and maintained in a safe and effective manner. The SRMTMP itself is Manual No. 14.

These manuals cover issues such as policies, strategies, operating processes & procedures, technical standards and associated performance indicators.

The SRMTMP, is for use by SA Power Networks, the Office of the Technical Regulator (OTR) and the Essential Services Commission of South Australia (ESCOSA), and lays out the strategy agreed between SA Power Networks and the OTR for the management of safety and technical compliance, in accordance with the Electricity Act 1996 and Section 7 of the SA Power Networks Distribution Licence.

The last audit of SA Power Networks’ Safety, Reliability, Maintenance and Technical Management Plan was undertaken by GHD in March 2013. One aim of this current 2014 audit is to examine whether the issues raised in the previous review have generally been addressed.

This audit report uses the same approach as previous audits and addresses the following:

A review of general company compliance to ensure SA Power Networks general approach in relation to compliance with SRMTMP obligations;

A follow up review to the March 2013 general compliance audit findings; and

A review of all of the current individual manuals for currency, accessibility, availability etc. and in particular whether the recommendations from the 2013 audit have been addressed.

A more detailed scope of work is outlined in Section 2 of this report.


2. Scope of Work

The documented audit scope for the 2014 SRMTMP audit is:

“To provide assurance that adequate and effective processes have been established which demonstrate SA Power Networks’ compliance with the Safety, Reliability, Maintenance and Technical Management Plan (SRMTMP) as required by our Distribution Licence”.

Specific objectives are to provide assurance that:

Policies and directives referred to in the SRMTMP are available, accessible, current and complied with;

Documents referred to in the SRMTMP are complete, accessible and current;

Records required by the SRMTMP are complete, accurate and securely controlled;

Management controls detailed in the SRMTMP are effectively implemented; and

Roles and responsibilities detailed in the SRMTMP are understood and effectively implemented.

For areas that were in compliance in the 2013 audit, a sample audit of safety and technical procedures against these elements was conducted to ensure compliance has been maintained.

For areas previously identified in the manuals as non-compliant in the 2013 audit (none), an update of the compliance status was determined by reviewing 100% of any non-complying procedures or elements and/or the suggested initiatives for improvement.

As with previous audits, this report comments on the level of compliance based on the findings of the investigations and extrapolates these to report on the full SRMTMP.


3. Review Methodology

The Network Management (NM) Group Manuals included in the audit are those in the Manuals Review Summary that appears in Appendix A.

As with previous audits, last year’s audit of the SRMTMP formed the basis of this 2014 follow up audit. The methodology involved the interview of all key staff responsible for the “ownership” of each of the manuals referred to in the SRMTMP and the interview of a sample of those staff whose operations were directly impacted by the policies, procedures and standards referred to in the manual. A list of the interview schedule is located in Appendix B.

To evaluate areas that were in compliance in the 2013 audit, a sample of elements was conducted to ensure compliance was being maintained. Last year’s audit was used as the basis of this part of the review. Each of the findings was compared with the current situation through the questioning of appropriate personnel. Samples of documentation and records were inspected as to their existence, location, currency and controls.

The audit investigated the topic areas as described in the various Safety, Reliability, Maintenance and Technical Management Plan Manuals. Questions tested staff awareness and compliance with the practices and procedures contained in documents referred to. The following is an example of the variety of sample information that was sighted to satisfy GHD’s auditor that compliance was being maintained:

SA Power Networks Intranet

Policy and Guidelines documents

Job Folders

Manuals

Works Programs and Worksheets

Action Plans

Databases

Field Instructions

Reliability Reports

Registers and Records

Meeting Minutes

Critical System Audits

Contractor Review & Endorsement documentation

Substation Security Access Register

Inspection checklists

Monthly Standards update newsletter

Electronic Bulletins

Hazard Logs

Standards and Regulations

E-Drawings


Similarly, for areas that were not in compliance in the 2013 audit (none), an update of the compliance status was reviewed and suggested initiatives for improvement were identified.

For reporting purposes, compliance or non-compliance with the 2014 audit has been reported in this report by exception only. The review of the individual manuals referred to in the Safety, Reliability, Maintenance and Technical Management Plan Manual was carried out as part of the overall review, and the findings have been documented according to each specific manual.


4. Compliance with General Audit Requirements The first part of this audit involved the review of specific objectives to provide assurance that SA Power Networks:

Policies and directives referred to in the SRMTMP are available, accessible, current and complied with;

Documents referred to in the SRMTMP are complete, accessible and current;

Records required by the SRMTMP are complete, accurate and securely controlled;

Management controls detailed in the SRMTMP are effectively implemented; and

Roles and responsibilities detailed in the SRMTMP are understood and effectively implemented.

This has been carried out using a similar approach to previous years, which looks at document control procedures, Network Operations procedures etc. to evaluate compliance. Findings and recommendations on this are listed in the following tables.


4.1 Overview of Documents Control

Policies and Procedures / Documentation / Records / Management Control

Control Objective To ensure that all manuals, standards and guidelines necessary for the efficient development, construction, commissioning, operation and maintenance of the distribution network assets: 1. Are available and staff know of their existence. 2. Are accessible by staff that need to reference them. 3. Are current for the purpose, i.e. reflecting existing industry best practice. 4. Are being adhered to by all staff in the implementation of the business processes.

Risk Exposure 1. SA Power Networks staff may not be able to apply current industry practice due to non-availability of these documents. 2. Works may be delayed resulting in inefficient business operation due to inaccessibility of documents or resulting in non-conformance

to the standards. 3. Out dated technology may be applied or works may not meet regulatory or legislative requirements. 4. Unsafe workplace may result due to non-adherence to the best practice guidelines.

Audit Question Findings Improvements 4.1.1 How does the

organisation ensure that all relevant staff are aware of its existence?

• All relevant Australian Standards, SA Power Networks internal Technical Standards, Policies and Procedures are listed in the Safety, Reliability, Maintenance and Technical Management Manual.

• The SRMTMP is used as a mechanism to ensure all relevant Australian Standards are referred to and complied with as appropriate.

• There is a monthly Information Update electronic publication that highlights any updates/changes to manuals, complete with links to the documents.

• Manuals are listed by title and number. • Manager Network Standards and Performance maintains a list of all Group Manuals. • All of the Manuals are available on SA Power Networks’ Intranet along with an update schedule. • Electronic access to Australian Standards, the Electricity Act Regulations and other pertinent codes

is available from within SA Power Networks’ Intranet. • Nominated staff (Manual Owners), as custodians of these internal controlled documents, are

responsible for the dissemination of revision information to staff in their respective groups.

• Nil.


Audit Question Findings Improvements 4.1.2 In what format do

the manuals exist? • All of the Manuals and Internal Standards, Policies, Procedures and E-Drawings are located on SA

Power Networks’ Intranet as controlled documents. • The Manager NSP maintains a complete set of controlled hard copy manuals in the event the

Intranet goes down. • Some internal office based staff still have controlled hard copies but attempts are being made to

reduce this number. All hardcopy owners are questioned on their requirement to retain hard copies of electronically accessible manuals, and removed from the distribution list where possible. Some operational staff still require hardcopies, for example the switching manual.

• The number of hard copies is slowly being reduced. • Some hard copy manuals are also issued externally as controlled copies. Holders are able to

reference the Internet for the currency index but not the latest version of the complete document in order to protect Intellectual Property.

• Provision of secure access over the Internet for external stakeholders i.e. Contractors, has been provided and is actively used.

• Nil

4.1.3 How is the currency of manuals and standards being maintained?

• The Manager NSP has the ultimate control of manuals, standards and E-drawings. • With all Manuals on the Intranet, manuals are required to be kept current in accordance with an

agreed update schedule (refer Appendix A). • Some manuals have not been reviewed in accordance with this schedule. There are valid reasons

for this (outlined in the findings for individual manuals). • Staff are informed of updates to manuals in a monthly update. The update is issued via the Intranet

and email and includes indication of manual updates with links to referenced documents. The update identifies the last review date of the Manual and the next review date.

• SA Power Networks maintains a register of hard copy owners. Selected staff still receive hard copies of the manuals but more are accepting electronic access.

• On-line subscription of Australian Standards ensures access to current Australian Standards at all times, allowing for appropriate manual updates.

• SA Power Networks has representation on a number of Australian Standards Committees related to the electricity industry, so are kept informed on changes. SA Power Networks also receives automatic update advice from Standards Australia. SA Power Networks also has representation on ENA (Energy Networks Association) that provides recommendations to Standards Australia at a higher level. SA Power Networks is also represented on the Electrical Technical Regulators Committee (ETRC).

• E-Drawing Manuals have drawing revisions lists, new are added, or existing updated on an ‘As Needs’ basis.

• Not on the immediate horizon, but a possible future project is the development of a Staff Manuals Matrix identifying which staff require access to or knowledge of what manuals based on job descriptions.

• Continue to encourage the use of the Intranet over the use of hard copy unless a case can be made for their retention where appropriate.

• Monitor manual reviews in accordance with the schedule.


Audit Question Findings Improvements 4.1.4 Is there a need for

new manual or guidelines to supplement the existing ones?

• Manuals are regularly reviewed and any issues are actioned and responsibilities documented in a project folder. Review process follows a structured flow chart and a checklist of review procedures, which are signed off and dated.

• Some manuals are in the process of upgrade/development, and are at various stages of completion as noted below: o Manuals 28 & 29 are being progressively phased out and replaced by Manual 35, Substation

Standards Manual. o Manual 36 Technical Standard – Insulation Coordination & Over Voltage Protection Standard is

located on the Intranet for historical purposes. • The hierarchy of manuals has been reviewed and is reflected on the Intranet. The hierarchy is

presented in a clear manner. • SA Power Networks is always looking to remove duplication from their documentation. A review of

the Network Directives to identify any overlaps and remove them is an ongoing exercise. Where information is required to be repeated, the directives will reference each other. Resource constraints has meant slow progress; not considered high priority, but will be included in future efficiency improvement activities

• The Telecommunications standards, manuals etc. is managed within the telecommunications group, with governance and review managed by NSP.

• Substation Standard Templates (SST) are being developed to ensure holistic design and installation consistency.

• Continue the phase out of Manuals 28 & 29. (ongoing)

• NSP to review substation and Telecommunications manuals and improve referencing where necessary. (ongoing)

• Continue development of SST’s

4.1.5 What are the issues regarding document consistency?

• In some instances there appears to be repetition of specific issues across various documents, potentially causing consistency problems. (is not considered to be a significant risk)

• It can also sometimes be unclear that a manual has been developed to satisfy specific obligations from other SA Power Networks documents such as Network Directives and Network Maintenance Manuals.

• Attempts are being made to minimise any duplication, minimise potential inconsistencies and improve the referencing between manuals wherever possible. The Manager Network Standards and Performance is providing the overview of the manuals review.

• The reduction in duplication is progressively improving as manuals are reviewed and updated. • The powerlines manuals are very consistent and are in standard formats and templates. Cross

referencing is checked with every review.

• Continue the manual review to remove any duplication across manuals. (ongoing)


4.2 Compliance Audit of Network Operations Control Objective: To provide a safe operating environment to SA Power Networks’ workforce and the contractor through clear instructions and good industry practice

guidelines on network operation and effective risk management. Risk Exposure: 1. SA Power Networks may be in breach of licence requirements.

2. Safety of SA Power Networks staff and contractors may be compromised due to an unsafe workplace or practices. 3. Customer supply may be interrupted. 4. Equipment performance and service has the potential of being compromised.

Audit Question Findings Improvements 4.2.1 Are the legislative

requirements being met?

• Major legislative requirements are translated to Network Directives, which are distributed to Nominated Staff in each group for implementation.

• Structure for legislative monitoring normally involves the Manager Network Standards & Performance, however the Manager Regulatory Affairs also has an obligation to regularly review and advise Manager Network Standards & Performance of any changes in legislation. There appears to be a multi-faceted review of all standards, acts, codes, industry guidelines etc. across senior management, with regular communication at group meetings.

• Regular updates are also provided to SA Power Networks from various industry authorities, e.g. ESCOSA, Australian Energy Regulator and through representation on various committees.

• When notified of legislative changes, these are assessed to determine the impact on the business and the affected people are liaised with to reduce this impact and addressed as required.

• The new nationally harmonised WHS legislation was enacted in SA in Jan 2013. • Material changes have been incorporated where necessary. A few minor issues will be incorporated

into manual updates at the next manual review. • Team Leaders are provided with WHS training.

• Minor updating of manuals to ensure compliance with the WHS legislation.

4.2.2 What system of operating procedures are in place?

• All processes are in the Network Management QMS. Many procedures in the QMS also have links to standard letters and templates. The QMS is accessible to all employees via the Intranet.

• SA Power Networks Construction and Maintenance Services (CaMS) & Field Services (FS) Groups develop Job Safe Work Procedures (JSWP’s) and Job Safe Work Methods and Forms as needed to be used by CaMS & FS personnel and contractors engaged by them. These procedures are developed and utilised to meet the requirements of the SRMTMP Section 3.9 (Safety Management – Job Folders).

• These JSWP’s are the “how to” documents that implement the overarching policies contained within the E-Drawings and Network Directives.

• JSWP’s (located on the Intranet site) include links to referred technical standards. • Regular audits (both internal and external) are conducted across FS activities.

• Nil.


Audit Question Findings Improvements 4.2.3 What is the control

procedure on the issue of job folders and job sheets?

• All initiated work is issued through the Network group. • Works orders issued through SAP go to FS Operations in Job Folders together with appropriate job

sheets, as per the requirements of SRMTMP Section 3.9. • Job Folders are issued to the works coordinator in the appropriate depot for planning and scoping. • Work breakdown sheet is issued to scheduler. • The Job Folder comes from Network in the first instance, and as it moves through the various

stakeholders, more information is added. This information covers planning the job, relevant drawings, switching sheets, any 3rd party information, mobile plant requirements, hazard assessment plan, risk assessments and any materials required.

• Risk assessments are filled out on a daily basis. • The Risk Assessment template is printed on the inside of each job folder. This requires completion

by the Team Leader for each job. • FS staff receive regular refresher courses on new or modified processes/procedures. • Training/refresher courses are mandatory and are managed through the Training School.

Scheduling and tracking of staff training is managed through SAP. • Safety Training is managed by SA Power Networks Safety branch. • A formal Network Access permit system is used for external access to the system with stringent

protocols to control risk.

• Nil.


Audit Question Findings Improvements 4.2.4 Is it the subject of

effective compliance monitoring and quality control?

• Contractors (supplementary labour) generally work under the supervision of FS staff and are audited randomly.

• Only qualified / authorised personnel on the Panel of Contractors are approved to operate / maintain substation equipment and the distribution system.

• Observational compliance audits are conducted on non-electrical contractors (e.g. civil) in relation to installation of SA Power Networks infrastructure. SA Power Networks maintains a Preferred Contractor database.

• Field Services is moving towards QMS for some of its activities, however not to ISO accreditation. • Network Access Permits from the Network Control Branch establish the protocol on network access

for operations and maintenance purposes. • Substation access is restricted in accordance with three levels of authorities and substation entry

requirements are fully documented in the Asset Access Manual, which can be accessed from SA Power Networks’ Intranet. Substation entry, accreditation and endorsement is also part of a joint agreement with ElectraNet. Online refreshment required every 12 months.

• Field Services Switching committee meets bimonthly. There are 3 committees: technical policy, operator’s technical and switching incidents review committees. Copy of minutes for OT and SI sighted.

• Switching incidents committee meet on an ‘as needs’ basis. • Reporting is provided to management by the Safety group, reporting against key performance

indicators, LTI’s, injury descriptions etc. • Annual KPI reporting to the OTR is prepared for the OTR by the Manager Network Performance and

Regulatory. • SA Power Networks maintains a training matrix for all employees detailing all mandatory training

requirements. In addition, there are individual training plans for each employee. This is managed electronically through ‘My Learning’.

• Nil.

4.2.5 What is the control process in terms of updates/changes to Manuals, Processes and Procedures?

• A Manuals Review Program exists and is updated annually (refer Appendix A). • The 2014 manuals review calendar is accessible through the SA Power Networks Intranet site. • The manual review process is managed by the Manager of NSP. • The nominated Manual “Owner” is responsible to ensure that the review takes place as programmed

and that relevant stakeholders are included in the review and feedback process. • Power Tech Services manages all Field Services Manuals and they issue controlled copies. • Staff receive email notification of updates, and are also debriefed at work group level. • Bulletins and DVDs are also sent to staff to advise of updates. • Toolbox talks at the start of each day.

• Nil.


Audit Question Findings Improvements 4.2.6 What are the

control measures in terms of protection and control equipment settings?

• Control and protection settings are adjusted where necessary through a system performance review taking into consideration business standards and risks.

• Multiple interruptions are a trigger for review of protection issues. A request is sent to Network Planning who review to see if protection settings are unduly sensitive or appropriate and make recommendations accordingly. The Protection group also check the daily log for potential events related to protection.

• Protection is not allowed to be changed on the network without going through the protection group. • There is a pending process and a confirmed process for protection settings. • A standard proforma on control and protection settings is issued, and a signed copy returned to the

Protection and Control Planning Manager for validation. • Protection requirements are all controlled through QMS: there are procedures for changing

permanent settings and temporary settings. Procedure 651 sighted. • Settings are calculated by the design team and then approved by the protection group. • Sample setting cards for new equipment sighted. • Balhannah substation – Aldgate CB settings sighted. • Routine testing of settings incorporated within substation maintenance procedures. • PSS6 is the system controlled protection setting sheet database. Most people only have read

access to this. Only the protection team has write access. • The control system has been in place for over 10 years and appears to be a mature system, well

understood, and providing appropriate controls.

• Nil.

4.2.7 Is safety obligation reflected in documented procedures?

• Safety requirements are documented in every manual. • Risk drives the safety commitments identified within the SRMTMP • A corporate WHS Network Plan identifies Actions, Responsibilities and Timelines. This Plan

provides strategic directions from which various action items such as Critical System Audits and responsibilities of staff are identified.

• Sitting under the SA Power Networks Corporate Plan are the individual business group WHS Plans, which are the group action plans, which are reported by the Business Group Manager back to the Safety group on a monthly basis.

• Debriefing back to business group staff is generally provided on a monthly basis. • Department Safety Meetings are generally held at bi-monthly intervals. These are generally

incorporated into Team Meetings/debriefings. • Job folders have hazard assessment checklists included as a final checking process that must be

gone through prior to job commencement. • Inside cover of job folders are printed with Risk Framework Assessment Matrix and Risk Context. • Technical standards, E-Drawings and equipment recommendations all have risk assessments done

that manage safety of personnel and plant. These risk assessments include consultation with end users.

• Nil.


Audit Question Findings Improvements 4.2.8 Is it fully

understood by staff, regularly monitored and complied with?

• Personnel interviewed throughout the audit indicate a strong safety culture with the general feedback that there is a very good level of understanding of and compliance with safety systems. The level of interaction from management down through to the workforce creates a very good understanding and appreciation of the risks.

• There is a WHS Annual Works Schedule that identifies the timing of checks of portable equipment, vehicles, personal protective equipment and the like.

• Workplace inspection forms are located on the Intranet. There are various forms for different situations, i.e. auditing contractors or apprentices, switching etc.

• Team leaders undertake compliance safety spot checks on the workplace as part of ongoing responsibilities. Four safety checks per month are conducted.

• Operations Managers undertake one safety check per month on switching operations. • Regularly audited by external auditors. • A standard observation form exists for general reporting of WHS non-conformance. • A risk assessment is completed for every job. • “Take 2 for Safety” books are carried by all staff allowing safety assessments to be undertaken for

even minor jobs, including changing street lights. These have recently been rebranded in line with the new company name.

• Regular WHS safety meetings and briefings are undertaken at multiple levels throughout the organisation.

• Weekly safety briefings at team meetings. • Toolbox talks are held by FS crew at the start of each day. • Risk assessments are conducted at each job site before commencement and where necessary job

procedures are adjusted and signed off to suit local risks. • Hazard Log procedures are well documented in the Safety, Reliability, Maintenance and Technical

Management Plan. The Hazard Log process and register can be found on the Intranet and are accessible by staff. This is organisational wide.

• The SA Power Networks Incident Reporting System (CURA) is accessible to all staff and appears to be used appropriately.

• Nil.


Audit Question Findings Improvements 4.2.9 Are the PPEs

adequate in the normal duty of work?

• FS staff are very satisfied with the adequacy of the Personal Protective Equipment provided and the level of management commitment to safety.

• PPE and licensing is checked monthly. • Ongoing monitoring and review of new and latest PPE is undertaken as it becomes available.

Purchasing department is continuously reviewing PPE for improvements. • All staff carry personally issued PPE, depending on their job requirements. • Testing procedures for PPE are in place and this is managed through SAP. • Open lines of communication up and down the management line allow for the fostering of a strong

safety culture. • Procurement are responsible for PPE procurement, however lines of communication between FS

and procurement allow for PPE safety requirements from the end users perspective to be communicated throughout the procurement process.

• Nil.

4.2.10 Do you have a systematic process to identify and register potential hazards?

• WHS Annual Works Schedule. • Potential hazards are identified through regular workplace inspections, in accordance with this

Schedule. • Scope of works for projects identifies the need for the completion of a Hazard Log sheet prior to

commencement of works. This is a backup to any previous assessments that may have been undertaken.

• Hazards and incidents are managed through CURA.

• Nil.

4.2.11 How often are the field staff being audited on safety awareness/ competency?

• Field Services groups are audited randomly, with a different group looked at each week. This includes contract labour employed on a daily basis. In this situation they are treated much the same as SA Power Networks staff. Supervisors are required to undertake 4 safety observations per month amongst the work group and managers are required to undertake 1 safety observation per month.

• Contractors who tender and undertake projects in their own right are assessed on several levels – initially through the accreditation process, and then subsequently through desktop and field audits in order to retain their accreditation. The quality of their work and compliance with the provisions of the contract are also monitored. Reaccreditation requires an assessment of contractors’ performance.

• Nil.


Audit Question Findings Improvements 4.2.12 How do you ensure

that switching control complies with the various WHS and regulatory requirements?

• SA Power Networks Switching Manual (No. 31) provides the guidelines and procedures on switching operations. This document has been reviewed through the SA Power Networks Switching Committee to ensure compliance with industry standards and legislative requirements.

• Permission for switching is checked and authorised by the Manager Network Control to ensure compliance with the Manual, and therefore with regulatory requirements.

• When selecting new equipment, part of the procurement process is to ensure that there is a switching operator’s instruction to go with it, and that the training centre is aware of the new equipment and has training programs in place.

• SA Power Networks WHS representative on committee. All changes to switching procedures undergo a risk assessment.

• Nil.

4.2.13 Do you have in place any emergency procedures?

• There is a Network Emergency Roles and Responsibilities document that is reviewed every year and includes roles and responsibilities requirements for specific event support specialists.

• An Emergency Procedures Manual (No. 13) exists as a high level document setting out the procedures and responsibilities in the event of an emergency under different scenarios, including floods, earthquakes and Kangaroo Island cable failure.

• Bushfire Risk Management Manual (No. 8) outlines procedures to minimise bushfire risk and is located within the Emergency Management Section of the Intranet.

• A summer preparation plan is used to provide a level of assurance that SA Power Networks has prepared itself for the high risk summer season. This plan is signed off by all staff who have been assigned a role and responsibility. Included in the signoff is the General Manager Network Management after all activities have been signed off.

• Nil.


4.3 Compliance Audit of Maintenance Management Control Objective: To ensure that optimal and effective maintenance strategies and practices are in place and all distribution network assets are being maintained

to provide reliable service at lowest life cycle cost. Risk Exposure: 1. Maintenance practices do not adequately address the safety and regulatory requirements or are inconsistent with industry practices.

2. The risk inherent in asset failures are not adequately detected or managed.

Audit Question Findings Improvements 4.3.1 Are the legislative

requirements met? • Legislative Requirements are translated to Network Directives, which are distributed to Nominated

Staff to undertake compliance. • Codes, Regulations, Acts etc. are regularly reviewed and SA Power Networks documentation

updated on an ‘as needs’ basis to reflect regular updates. • Many different audits are undertaken to ensure all legislative requirements are met, for example

AEMO conducts audits of meters and issues CoCs. • Documents have on the whole been updated to match obligations, with the exception of some minor

acronyms which will be changed as the manuals are reviewed in their review cycle.

• Nil

4.3.2 Have best practice maintenance strategies been introduced?

• The Network Maintenance Manual (No. 12) sets out high-level maintenance policies and strategies for the organisation and is prepared based on industry good practice in accordance with Australian Standards, ENA guidelines, IEC standards, and adapted for local issues.

• Maintenance is condition based at the moment, i.e. for x condition, undertake y maintenance. SA Power Networks is moving to a risk based approach through the use of a recently developed Condition Based Risk Assessment tool (CBRM). The tool is being predominantly used for ‘reset’ but will be rolled out across the business after reset.

• The CBRM enables assets to be modelled and given a health index. Six main asset classes are being modelled.

• Benchmarking of technologies as well as benchmarking against other Utilities is undertaken. SA Power Networks is reviewing Lidar Trial to assess potential for use in vegetation management (i.e. within the required clearance zones). Other uses across business groups is also being assessed.

• SA Power Networks benchmark some maintenance practices against other Australian utilities, currently looking at Western Power Inspection Program.

• The Asset Management group has engaged external consultants to develop new Asset Management Plans over the last 12 months.

• Program in regular external maintenance bench marking reviews (maximum 3 yearly).

• Set milestone target dates for tool development.


Audit Question Findings Improvements 4.3.3 Are you aware of

any documented maintenance plan and inspection procedures related to the type of assets under your responsibility?

• Maintenance plans for various asset groups are available, e.g. substation plant manual (covering switchgear, relays and ancillaries etc.), overhead lines etc. Nominated tasks are identified; predominately defect management, with preventative work also included.

• The Network Maintenance Manual (Manual 12) shows the maintenance requirements, with the procedure for how to undertake the maintenance described in the detailed maintenance plans.

• Asset Management Plans exist for all major classes of asset. • The 5 yearly review is appropriate as this is set up around the regulatory reset to request

funding • All maintenance is assigned using MRV to assess risk. • Projects are issued to Field Services based on the MRV. For projects over $20k, a project is

raised and issued to FS. • The works are issued to FS to manage. FS contract out the work if they are unable to undertake

it themselves. • The Line Inspection Manual (Manual 11) sets out the procedures, information requirements and

the prioritised actions for the inspection of SA Power Networks’ distribution system assets. • The Substation Inspection Manual (Manual 19) has also been developed.

• Update manual sections where required as part of ongoing upgrade.


Audit Question Findings Improvements 4.3.4 When were the

plans last reviewed and what are the review procedures?

• The Manuals set out the strategies. The plans are then developed to implement these strategies and will include the activity to be performed and the allocated budget.

• There are plans to refurbish or remove from service obsolete plant as necessary; however these generally have a lower priority.

• New Asset Management Plans are being developed by the Strategic Asset Management Group to cover 6 key asset categories. These are designed to replace the existing suite of AMP’s.

• These Asset classes are: o Poles o Conductors o Substation transformers o Substation Circuit Breakers o Underground cable o Ground level switchgear

• These 6 classes have been selected as they cover over 85% of total Assets. • New AMP’s are due for release at the end of April 2014 for review. These will be updated for ‘staff’

release as part of the ‘reset’. • Maintenance analysis and strategy are usually reviewed as deemed necessary by the Asset

Operations Group. • The Manager Network Standards & Performance is responsible for the management of the review

programme, with individual Group Managers responsible for delivery of the reviews. • The Network Maintenance Manual (Manual 12) will be reviewed again as part of the regulatory reset

process and will be updated to cover the new asset management plans once developed.

• Complete review by consultants.


Audit Question Findings Improvements 4.3.5 What other audits

are in place to ensure that maintenance practices are effective and adequate?

• Ad hoc internal and external audits of maintenance practices are still being carried out. • Feedback from FS staff on appropriateness of procedures and processes is encouraged at Team

Meetings. • Equipment failure investigation outcomes feedback to maintenance manuals. • A failures database on SAP is being developed over time. The capture of failures on SAP is not as

“user friendly” as it could be. • The level and extent of asset data capture has been expanded over the last few years. The Priority

Asset Tool was developed to assist with increasing asset knowledge in the lead up to the 2015 reset; however a new system is being assessed for long term integration into and across the business..

• Asset Performance Review Committee generally meets regularly to discuss amongst other items the maintenance effectiveness. The outcomes from these APRC meetings feed back into maintenance plans.

• Internal audits of internal processes are undertaken as part of SA Power Networks’ QA process. SA Power Networks is accredited to ISO 9001 and its QA procedures are detailed on the Intranet.

• SA Power Networks have created a procedure for inspection of pole plating jobs. This is undertaken by external contractors to ensure that they are following the E-Drawings.

• Officers attend routine planning meetings at depots to get feedback from staff.

• Nil

4.3.6 Provide evidence of RCM techniques used on network components.

• RCM is not used as such but the seven key principles of RCM relating to context, consequences etc. are used. Whilst the principles are in use, we recommend that SA Power Networks use the RCM or the principles be reviewed as part of an external maintenance review as recommended elsewhere in this Audit. We understand that there is a new management regime that will explore this further.

• Risk rating tools have been developed. These tools extract data from SAP. The data can roll up individual defects to the feeder level allowing staff to identify trends and to prioritise defect maintenance activities.

• SA Power Networks follow the principles of Root Cause Analysis (RCA) • It is SA Power Networks’ intention to undertake RCM on a more regular basis. • The level of RCM will be “flushed” out as part of the AMP redevelopment. • The strategy group will plan the RCM requirements. • The Operations group will undertake the RCA.

• Nil


Audit Question Findings Improvements 4.3.7 What are the

quality assurance processes on inspection?

• Prioritised inspection checklists and inspection schedules are in place and performed by each group, e.g. 10% overhead lines to be inspected each year. A new audit regime has been implemented for contractor Line Inspection works and being expanded to include SA Power Networks’ Asset Inspectors.

• Field Services staff also undertakes a self-audit of works and these are reported on monthly. Includes issues such as inspections, cyclic cutting and completed jobs, standards of work, failure rates etc.

• Maintenance frequency is determined at the strategic level. Substation Maintenance Planner provides a list of planned maintenance jobs for an entire year to the FS Group.

• The Maintenance Standards Officer reviews all notifications before they are issued to FS. • The Maintenance Standards Officer is an ex-inspector, very familiar with inspection processes and

data. This officer will view the photos taken on site, if he believes the assessment to be incorrect, it will be sent back to the inspectors to be looked at again.

• APRC participation appears to provide cross company representation. • APRC monitors failure trends (causal and asset specific) and instigates further investigation if

necessary. • A specific reliability staff member has responsibilities that include review of daily and monthly group

meeting reports for NM and FS.

• Nil

4.3.8 Who are the key persons responsible for the maintenance planning and standards requirements?

• Roles and responsibilities appear to be well understood. • The group has been split into two – Maintenance Strategy, and Maintenance Operations. • Maintenance Operations Officers for a given asset class will review all projects above $20k before

projects are created and issued to FS

• Nil.

4.3.9 What is the management role in regard to maintenance and inspection activities?

• Management assess and report on what has been completed by the field, and estimate work to be done based on how they are performing.

• The APRC is represented from relevant stakeholders across the business.

• Nil


Audit Question Findings Improvements 4.3.10 How are the

maintenance activities being planned?

• An Inspection Plan based on frequency deemed appropriate has been developed for each of the SA Power Networks asset types. For example Substation Preventative Maintenance Plan and Line Inspection Plan where the frequency of inspections is risk based, using the corrosion zone as the inspection frequency driver. High corrosion zones are inspected on a 5 year cycle, with others on a 10 year cycle.

• The strategies developed within the new AMP’s will feed into the maintenance activities. • A significant portion of work is reactive as a result of the findings from inspections or general asset

failure. Consequently it is often difficult to plan maintenance activities. • Notifications (defects) are logged by the inspectors into SAP. These are reviewed to check the level

of detail provided and the assigned priority and the budget allocation before being assigned to FS. • FS generate work lists to suit resource and geographical requirements. A risk assessment is

conducted if there are any changes to priority order. • Work orders are generated from the SAP system. • Joint NM / FS meetings are held regularly to discuss FS Performance Reports and other issues

such as Actual versus Planned Performance and other budget issues. • Maintenance is undertaken taking into account the MRV scores, to ensure that the highest ranking

defects are always cleared as a priority. If there is no further inspection of the asset, the MRV score is automatically increased over time to ensure that the defect works its way up the list, or is reinspected to reassess the score.

• Nil.

4.3.11 What is the quality process in closing off maintenance jobs?

• The maintenance strategy at substations is incorporated in Network Maintenance Manual 12. This subsequently drives the annual works plan.

• Maintenance checks on substation equipment must be signed off. Test results are returned to Substation Planning group for confirmation. Priority issues and changes to the agreed plan are discussed with the Substation Planning Manager.

• Notification and orders are created at the start of a job. The notification is linked to the plan and is closed at completion of the work to enable effective reporting of work completed.

• NM project manager will review folder, check that SAP has been updated and then issue any payments and close off job.

• Report on projects on a monthly basis. • Will follow up if haven’t received job folders back for work that has been completed?

• Nil.

4.3.12 Do you consider asset data / information in SAP complete and adequate for maintenance purpose?

• The level of asset data information in SAP is considered to be inadequate for certain purposes, but the new processes and systems such as PAT and the Geophysics system will capture and fundamentally improve information gathering procedures, improve SA Power Networks knowledge and understanding of the assets

• Provision for more comprehensive inputs will allow for more detailed and better analysis of data. Looking to automate processes where possible.

• Asset register details for some new plant / equipment in existing substations still require updating. This register update is continually being improved.

• Continual update of asset register and improve information-gathering process.

assessment etc. • Review of performance includes research by SA Power Networks through discussions with people

who have used this equipment previously. • SA Power Networks negotiates with manufacturers for warranties etc. • Anything that is purchased and goes into stock has to be approved by the Network Standards and

Performance Group. • Procedure 935 shows the process for introducing new equipment.

• Nil.


Audit Question Findings Improvements 4.4.1.5 How rigorous is the

analysis of tender specification during the procurement?

• Tender analysis is very rigorous, with occasional feedback that the process sometimes takes too long. There are many things to take into account, and for new products the process can take longer than for existing products.

• Compliance to technical standards of equipment normally based on manufacturers’ test results prepared by accredited agency, e.g. NATA.

• SA Power Networks engineers witness equipment tests as and when necessary during the procurement process, and for new products, further testing may occur at SA Power Networks’ Angle Park facility or in trial conditions. The analysis could take 1-2 years in this case.

• Whole of life cost approach is taken, including upfront costs, training, E-Drawing updates, tools, time to install and maintain and logistics costs.

• WoLC tool initially developed for Pad Mount Transformers but is modified for other equipment on an “as need” basis.

• Internal standards to cover specific areas such as critical assets or construction methods are developed, as needed (e.g. E-Drawings).

• SA Power Networks internal standards are generally viewed by staff as being more stringent than industry standards.

• A Synergy Group comprised of sister companies Powercor Australia (Western Vic) and Citipower (Melbourne CBD) along with SA Power Networks representatives, reviews standards and practices with the view to standardisation and the associated operational and cost benefits that may derive from this. Whole of life principles are considered as part of this process.

• Nil.

4.4.4.2 Are there nominated staff with full knowledge of AS, IEC and ENA guidelines?

• Manager NSP reviews regulations and industry body guidelines, and provides appropriate feedback to Group Managers on an as needs basis. This is a new role for the NSP and is required to interpret standards and put it in more easily understood terms and explain what it means to the business.

• SA Power Networks is represented on ENA committees and sub-working groups. • Some staff also sit on CIGRE committees and provide feedback to relevant staff.

• Nil.

4.4.4.3 To what extent are these standards adopted?

4.5 Compliance Audit of SA Power Networks Performance Indicators Control Objective: To ensure that SA Power Networks’ performance matches the industry standards, electricity supply efficiency is managed, environmental issues are

actively managed, and the economic performance of SA Power Networks businesses and its customer’s welfare are sustainably managed. Risk Exposure: Performance of SA Power Networks falls below industry best practice or failure to comply with Technical Regulator’s licence requirements.

Audit Question Findings Improvements 4.5.1 Are the

performance indicators reported in the form of exceptions or are they part of the regular management reporting?

• Performance Indicators identified in the SRMTMP are covered across a number of platforms within SA Power Networks.

• Performance Indicators are a combination of both regular management reporting and exception reporting.

• Performance indicators are available on a daily basis (estimates), but are formally reported on a monthly basis. This information is extracted from the daily reports from the NOC Log.

• Reporting is provided to management on a monthly basis, by reports and also representation at monthly management meetings as required.

• Incentive scheme KPI’s tracked and reported. Where KPI’s are trending below target, the cause of the performance is assessed and any mitigating strategies to improve performance is identified, allocated and tracked. Performed well last financial year but tracking unfavourably this year.(mainly due to the impact of numerous severe weather events)

• SAIDI and SAIFI reported as per licence requirements. • Performance reporting to the Regulator is on a quarterly and annual basis. • Street lighting services standard (% compliance) reported monthly against

performance standards. Information is provided by Field Services. Target is 97%. • Causal analysis on SAIDI completed and reported on monthly / quarterly on

standard ESCOSA proforma and Intranet.

• Nil.


Audit Question Findings Improvements 4.5.2 Are the regulatory

reliability reporting standards being complied with?

• Regulatory reliability standards in the form of supply interruption durations, frequencies, and others are reported quarterly and annually to ESCOSA in the required format.

• Minor changes were made to the annual reporting requirements template with formatting changes and two (2) KPI’s removed. (OP 1.3 and OP 1.4)

• Reporting is on the basis of the seven state geographical (ESCOSA) regions serviced by SA Power Networks. These are best endeavours standards and do not incur financial penalties. AER reporting is based on four feeder categories (CBD, Urban, Rural Short and Rural Long) – the AER’s service incentive scheme (STPIS or SPS) can incur financial penalties.

• Quality of supply is reported quarterly and annually. • Regulatory codes are accessible via the SA Power Networks Intranet. • The AER and ESCOSA produce an annual report on SA Power Networks’

performance.

• Nil.

4.5.3 Are the performance indicators required clearly understood by staff responsible in terms of measurement, basis etc.

to view on the Intranet. • Results are discussed at numerous forums including team meetings, bi-monthly

branch meetings and the like. • The SPS has a dollar value associated with it as deviation from target incurs

penalties, so this is very important to staff and is widely understood.

• Nil.

4.5.4 Is there a set of industry benchmarked figures?

• Industry benchmarked figures on SAIFI and SAIDI are available. • Distribution Licence specifies standards on reliability of supply. • The Energy Supply Association of Australia (ESAA) produces an annual distributor

survey containing benchmarking data which SA Power Networks contributes to. • Most States now support the establishment of a core set of electricity industry KPI’s

and there is movement in this direction, however there are still different reporting requirements for AER and ESCOSA but these will generally align in the next regulatory period.

• Reliability and Power Quality Working Group (R&PQWG) has been set-up by ENA with the aim of obtaining national consistency in safety, reliability etc. Two SA Power Networks staff sit on this working group.

• Nil.


Audit Question Findings Improvements 4.5.5 Is data collected

and reported in accordance with documented policies, practices and procedures and how accurate are they?

• QMS 604, 605 and 608 are the appropriate procedures. • The SRMTMP identifies the ESCOSA performance indicators that are required to be

reported. • A review of a number of performance measure reports collected across the

business indicate the ESCOSA required data is collected by the appropriate business group and reported back up to the appropriate stakeholders, committee including the Network Performance & Regulatory Manager.

• Performance analysts have a clear understanding of the measurement basis in accordance with Australian Standards. They are all experienced personnel.

• Average times to repair street lighting reports are automatically generated in SAP following generation of works order.

• Existing SCADA and Telephone Dialling Units provide instantaneous switching on and off times of feeders.

• The OMS allows SA Power Networks to report actual rather than estimates of customers affected by an interruption, through its GIS capability. Continual improvements are being undertaken to improve the quality of data relating to customer to asset linkages.

• Performance results are checked and audited annually by external 3rd parties.

• Nil.


Audit Question Findings Improvements 4.5.6 What sort of

feedback loop is provided in these performance indicators?

• Numerous feedback platforms across the business as noted below. • Monthly figures reported to the SA Power Networks Management group and the

Board and distributed to management staff. • Monthly figures provide FS with key trends and the SPS Steering Committee with

required information. • Field crews provide feedback at roadshows. • Reliability trend data is fed back to the Reliability Operations Manager for future

consideration in system performance improvement. • Network Operations Centre data entries, such as outages, resolutions etc. are

checked as required after the event by network performance staff as part of the calculation of reliability performance. Information is fed back to the NOC (NOC Log) if there is an issue or anomaly.

• Data from NOC logs are regularly reviewed for inconsistencies or any obvious data entry errors. Outages are internally audited on a regular basis by running OMS reports and checking against NOC logs.

• HV Daily Summary reports on HV interruptions on a daily basis. • Feedback provided from ESCOSA in the form of letters on an as needs basis. SA

Power Networks reviews any ESCOSA comments and report back with response. • Regular email performance updates provided by the GMNM to all staff.

• Nil.

Audit Item 2013 Recommendations Findings 2014 Recommendations 4.3.2



• The Network Maintenance Manual (No. 12) sets out high-level maintenance policies and strategies for the organisation and is prepared based on industry good practice in accordance with Australian Standards, ENA guidelines, IEC standards, and adapted for local issues.

• Maintenance is condition based at the moment, i.e. for x condition, undertake y maintenance. SA Power Networks is moving to a risk based approach through the use of a recently developed Condition Based Risk Assessment tool(CBRM) The tool is being predominantly used for ‘reset’ but will be rolled out across the business after reset.

• The CBRM enables assets to be modelled and given a health index. Six main asset classes are being modelled.

• Benchmarking of technologies as well as benchmarking against other Utilities is undertaken. SA Power Networks is reviewing Lidar Trial to assess potential for use in vegetation management (i.e. within the required clearance zones). Other uses across business groups is also being assessed.

• SA Power Networks benchmark some maintenance practices against other Australian utilities, currently looking at Western Power Inspection Program.

• The Asset Management group has engaged external consultants to develop new Asset Management Plans over the last 12 months.





• Update manual sections where incomplete as part of ongoing upgrade.

• Maintenance plans for various asset groups are available, e.g. substation plant manual (covering switchgear, relays and ancillaries etc.), overhead lines etc. Nominated tasks are identified; predominately defect management, with preventative work also included.

• The Network Maintenance Manual (Manual 12) shows the maintenance requirements, with the procedure for how to undertake the maintenance described in the detailed maintenance plans.

• Asset Management Plans exist for all major classes of asset.

• The 5 yearly review is appropriate as this is set up around the regulatory reset to request funding

• All maintenance is assigned using MRV to assess risk.

External Consultant has been engaged to review current practices, procedures, communication practices and the like. SA Power Networks will review these findings and will feed any relevant items into Reset.

• Use of commercial weather company (Weatherzone) to provide specific and relevant weather information that assists SA Power Networks in monitoring and predicting high risk weather events.

• A new GIS system call Dekho has been developed, which is tailored to bushfire management and allows graphical identification of where the outstanding defects are and what switching is required to clear. Currently not a live feed but updated on a weekly basis. Is there any benefit in making this system a “live” feed? Feedback is that weekly update is appropriate, but would suggest move to a live feed to minimise potential for “human” error in the weekly updating process.

• SA Power Networks has created an Emergency Management webpage on their intranet. This page shows past FDL events,

• Complete the full scale review of high bushfire risk areas.

• Continue progression of loss assessment model.

• Investigate whether Dekho should be an upgraded to be a “live feed” rather than updated on a weekly basis.

• Continue towards SCADA recloser control.


Audit Item 2013 Recommendation Findings 2014 Recommendations media releases from the CFS advising of extreme conditions and links to the Weatherzone site. All staff have access to this page.

• A spreadsheet tool has been developed internally to capture wind speed data from the BOM. The tool colour codes the data to flag any issues and emails these issues to alert relevant personnel.

• Working towards SCADA control for all reclosers, however this is still a long way off.

• Manual 8 has an impact on the content and use of other SA Power Networks manuals, therefore the continual update and linkage to other manuals needs careful ongoing management.

6.5 Manual 9 – Telecommunications Construction Manual

Audit Item 2013 Recommendation Findings 2014 Recommendations 6.5.1 • Document maintenance requirements

as information becomes available. • Suite of E-Drawings. Sign-off is provided by senior Managers

including FS, Network Operations, and Engineering Standards etc.

• E-Drawings are not regularly reviewed/updated due to limited changes to installation design identified or technological changes. This is deemed an appropriate level of review.

• New Fibre Cable Manual was being developed. Its content will be dependent on NBN requirements and will be drawing based. All works associated with telecommunications is managed within this group (i.e. design, inspections, asset management etc)

• Management of the EDrawing review process is by NSP. • NBN assets fall within the Standards group, not within

telecommunications. • NBN e-drawings being developed/managed by Standards Group. • AMP’s being developed to match the SA Power Networks

standard format.

6.6 Manual 10 – Electricity Industry of South Australia Acts and Regulations

Audit Item 2013 Recommendation Findings 2014 Recommendations 6.6.1 • Nil. • The Manual contains a link to the SA Parliamentary web site as

well as providing detailed plans prepared by SA Power Networks of the Bushfire and Non Bushfire Risk Areas. (These detailed plans are prepared on an individual house block scale and differ from those in the Regulations for purposes of clarity).

• The Bushfire Zones were last reviewed, finalised and issued to the OTR in December 2010.

• Manager NSP reviews Acts and Regulations, assesses changes and provides appropriate commentary/explanations, to all manual owners and stakeholders who have access to the manual.

• The asset owner advises of any changes. • SA Power Networks is developing a submission on possible

changes to vegetation regulations. – to be submitted to the OTR.

• Information updates are issued to staff by a monthly newsletter. • The Government Gazette is reviewed for minor changes and

where necessary Manual 10 is updated to reflect changes. • All pertinent codes, standards, acts, regulations etc. are easily

accessible via SA Power Networks’ Intranet. • Manual 10 is accessed from within SA Power Networks’ Intranet

in the same location as the link to all other codes. The predominant component of Manual 10 is effectively a copy from the SA Acts & Regulations, although formatted to SA Power Networks requirements. SA Power Networks feels that the manual is important for version control. Only 4 people get a hardcopy of this manual, and these are people that use it every day. If the manual was removed, these people might print their own copies anyway, and then version control would be more difficult.

• Provide submission on possible changes to vegetation regulations to the OTR.


6.7 Manual 11 – Technical Standard – Line Inspection

Audit Item 2013 Recommendation Findings 2014 Recommendations 6.7.1 • Continue move to MRV.

• All inspectors to be provided with Inspection Accreditation Cert 2 – Asset Inspection when the course becomes nationally accredited.

• Develop target milestones for the review of the Line Inspection Manual.

• Complete BFRA inspections by March 2014 and remaining backlog thereafter.

• The Manual was last published in October 2012. The review frequency is 3 yearly; however it can be reviewed at any time to cover rising issues.

• All asset inspectors carry a hard copy of the manual and are issued with updates.

• The manual covers line inspections, investigations and training of safety inspectors.

• The manual covers approximately 25 procedures. • All contracted Line Inspectors have completed “Cert 2 – Asset

Inspection training and received accreditation. • A Line Inspection Review Committee has recently been

established. This committee will review the manual and identify areas where the Manual can be made clearer and less subjective.

• The LIRC meets on a monthly basis. • Contract inspectors are audited regularly and the results

reviewed by management. There are several levels of inspector competency, and the level dictates the frequency of audit.

• The asset inspector audit database was sighted. At the time of the audit there were 14 out of 34 external contractors who are classified at the unsatisfactory level (some due to interpretation issues which have been addressed with the contractor or in the manual). At this level SA Power Networks are required to audit each inspector on a monthly basis correctly placing pressure on resources to meet requirements.

• The objective would be to have as many inspectors in the top level as possible to provide confidence in the Line Inspectors

• At least 1 external inspector was classified ‘unsatisfactory’, however was not being audited in accordance with the audit QMS 224 policy due to a temporary resource constraint, which has since been addressed.

• Underground inspections are performed but to a limited extent (mostly involving checks of transformers, service pits, in-line with industry practice).

• Motion tablets and Toughbooks are used by inspectors for data capture. The inspection results are uploaded into SAP. The

• Close the Contractor audit backlog. • The high number of contracted Line

Inspectors currently in the “Unsatisfactory” category provides an indication that existing practices may require improvement. Review Line Inspection processes, practices and procedures (e.g. training, contractor management etc) to identify if there are any practices that require improvement.

• Implement improvement practices where required.

• Seek confirmation from Helistar that these Pre Summer bushfire patrols are conducted in accordance with the checklist in M11.

• Review Helistar contract and update agreement to reflect specific pre-summer patrol checklist requirements if required.


Audit Item 2013 Recommendation Findings 2014 Recommendations inspections incorporate a newer risk rating score system (MRV).

• Network Maintenance Manual (M12) “drives” the Line Inspection strategies.

• Inspection frequency strategy takes into account equipment anniversary dates.

• There is currently a backlog of work (thermography, line inspections). The initial focus was high bushfire risk areas, and this was completed end of 2012. The next focus is the bushfire risk areas. MBFRA’s were targeted to be completed by March 2014, however changed inspection procedures using the ESRI based Priority Asset Tool (PAT) have been slower than anticipated resulting in a revised BFRA completion by the end of 2014. Verbally advised that this has been reported to management.

• The use of helidrones for line inspections is now included in inspection methods. Used for 33kV and 66kV lines, particularly for suspension insulators that need to be viewed at eye level. The drones take high resolution images of the asset and these can then be analysed from the office.

• Pre Summer bushfire patrols are conducted upon request by external contractor Helistar. M11 includes a checklist for these patrols. The current agreement “QT 1309” was sighted. This agreement covers a range of services provided by Helistar. The contract appears to be the original contract, which was recently extended. Whilst the feedback during the audit was that the patrols are undertaken in accordance with M11, and then by default the referenced checklist, there appears to be no direct reference in the contract to the checklist in M11.


6.8 Manual 12 – Network Maintenance Manual

Audit Item 2013 Recommendation Findings 2014 Recommendations 6.8.1 • Determine the type and extent of

defects as the inspection backlog is completed.

• The coversheet of M12 indicates published in 2012, but Date of Issue” referenced inside M12 are June 2013.

• Operational Asset Management Manager (OAMM) is a key stakeholder in M12, but is not included in the Stakeholder Organisation Chart.

• Manual includes asset management strategies and principal maintenance strategies.

• The manual was last issued in October 2012. The manual will be reviewed again before the Reset.

• The group has been restructured over the last 6 months to help clarify roles and responsibilities.

• The Victorian Bushfire Inquiry identified a number of recommendations relating to the electricity sector. SA Power Networks have been monitoring the inquiry and have identified a number of findings and recommendations and have incorporated appropriate findings into their maintenance strategies. These have been incorporated into the current issue of the manual, and the next review of the AMPs will look to ensure that all findings have been addressed.

• There is an understanding that there is a gap in some Asset information and is being actively closed.

• With an increased inspection regime the number of defects being identified has increased significantly, resulting in defect closeout pressure.

• Target closeouts are not being achieved because of additional defects identified.

• Without either a change in defect closeout strategy or an increase in resources and budget targets will not be met.

• SA Power Networks in process of reviewing defect close out strategies with the aim to meet and discuss with the OTR, seek strategy acceptance before reset submission.

• Correct cover sheet publication date • Add the OAMM to the organisational

chart. • Continue with defect management

strategy discussions with the OTR to achieve agreement.


6.9 Manual 13 – Network Emergency Procedures Manual

Audit Item 2013 Recommendation Findings 2014 Recommendations 6.9.1 • Nil. • Covers the different types of emergencies that could possibly

the OTR, or internal. Each PI was checked, with the exception of the three (3) Performance Indicators in the Technical Management Indicators Subgroup, the reporting was sighted.

• The wording for three SRMTMP Technical Management Indicators, all relating to voltage, did not match the wording in the Annual Operations Performance Report to ESCOSA. This appears to be a relatively minor issue; however the SRMTMP wording should be updated to reflect the ESCOSA wording.

• SA Power Networks are aware that AS 5577-2013 ‘Electricity Network Safety Management Systems’ has been published. This standard is not included in the technical requirements as specified in the Electricity (General) Regulations 2012 for inclusion in the SRMTMP and consequently it has not been specifically addressed in the SRMTMP. It should be noted that in SA Power Networks’ opinion, the existing SRMTMP and associated systems and processes generally comply with the requirements of AS 5577.

• Review and update wording In SRMTMP section 6.1 subgroup ‘Technical Management Indicators’ to reflect ESCOSA requirements.


6.11 Manual 15 – Asset Management Plan

Audit Item 2013 Recommendation Findings 2014 Recommendations 6.11.1 • Decide whether Manual 22 is to remain

a manual. • Ensure that next review of the Asset

Management Plans addresses the findings from the Victorian Bushfire Inquiry.

• Nil


6.18 Manual 25 – Distribution Handbook – (NPO’s Manual)

Audit Item 2013 Recommendation Findings 2014 Recommendations 6.18.1 • Undertake a detailed check of

references to Standards. • We recommend that the next manual

update include cross-referencing of the tool locations. We understand that there is a level of junior/new engineers’ brought into this group each year. The cross referencing would provide for improved tool accessibility.

• This manual is more a reference document than a standards document. It is quite detailed and includes calculations, terminology and drawings. The manual covers the underlying principles for how to design.

• The Manual was scheduled for review in March 2010, but this has not been undertaken as yet. Due to the time and effort involved for updating manuals 17 and 18 for NECF, this manual revision has been on hold. The 2004 issue (current version on the Intranet) was a major rewrite so the next review is not expected to be too major. It is a ready reference document (essentially a technical manual) and picks up latest standards.

7. Review of Specific Areas Requested by the Office of the Technical Regulator (OTR) 7.1 Review Requirements

At the request of the OTR, audits sometimes include specific review of nominated areas of the SRMTMP. No request was made by the OTR for the 2014 audit.


8. Conclusions The following is a list of the key findings and recommendations:

1. Compliance with the General Audit Requirements

It was found that issues identified in the 2013 review (mainly minor) have been either attended to or are being progressed.

Areas of compliance from previous audits were generally found to be satisfactory and some additional findings have been referenced. As with previous reviews, this is not necessarily a major issue however, because the majority of the recommendations are directed at procedural improvements that can be undertaken in the longer term.

The previously identified inspection backlog continues to be addressed with MBFRA’s targeted for completion by the end of 2014. NBFRA’s are targeted for completion by 2018. This increased inspection regime has however resulted in an increase in the number of defects being identified, which will require either a change in the defect management strategy or an increase in funding in the next Reset to ensure that they are adequately managed. We understand that SA Power Networks will be discussing the defect management strategy with the OTR to achieve agreement and will be seeking appropriate funding to complete the inspections and the identified defects in the next regulatory period.

Accessibility to information contained on the Intranet has seen continual improvement, with documents and manuals being located in a more “user friendly” system. All personnel interviewed were able to navigate easily through the Intranet and locate the manuals, procedures, directives, policy documents and the like where referenced within the manuals of the SRMTMP.

Roles and Responsibilities seem well understood, and all staff interviewed were familiar with their job descriptions and able to refer to other documents that place requirements on them.

The introduction of new, nationally harmonised WHS legislation on 1 January 2013 necessitated an update of business documentation and practices to ensure that the business meets its obligations under this new legislation. On the whole it appears that SA Power Networks have changed the majority of their documentation and practices, with only exceptions in instances such as minor WHS acronym referencing and the like. These are not considered material and are to be updated at the time of the next manual cyclic review.

Staff interviewed highlighted a number of improvements that have occurred over the last 12- 24 months.

2 Findings on Previous Recommendations

There are a number of recommendations that are the same as previous year’s recommendations, with some recommendations going back more than several years. These are either considered to be a work in progress, or have been identified by SA Power Networks as a lower priority item.

3 Review of Individual Manuals

The SRMTMP manual reviewed for this audit was the August 2013 issue.

There has been some significant improvements and updating of manuals over the last few years for a number of reasons, including:

Preparation for the 2015 – 2020 Network Distribution Determination (reset);

The changing regulatory environment such as the nationally harmonised WHS legislation;


Risk reduction;

Greater emphasis on either simplifying or clarifying instructions and procedures; and

The rollout of the NBN.

The reset preparation in 2013 and 2014 has seen significant works on the review and updating of a number of manuals including;

Manual 12 (Network Maintenance Manual); and

Manual 15 (Asset Management Plan) and the suite of category AMP’s that sit under M15.

As the reset preparation is ongoing at the time of this audit, the changes were incomplete.

There are a few manuals (28 and 29) that are being progressively phasing out.

4 Review of Specific Areas Requested by the Office of the Technical Regulator (OTR)

The OTR did not request any additional review for the 2014 audit.

Conclusions

Overall it is considered that adequate and effective processes have been established that demonstrate SA Power Networks compliance with the SRMTMP and that the organisation has embraced the principles outlined in this and previous audits.

The majority of the issues raised are considered minor, are procedural in nature and are considered to be a work in progress. While a number of issues appear to be occurring from year to year, they are considered to be minor in nature. Explanations for reasons are contained within the body of this report. Many of these are progressing or will be progressed in the coming years.

The inspection backlog continues to be addressed with MBFRA’s targeted for completion by the end of 2014. We understand that SA Power Networks will be discussing the defect management strategy with the OTR to achieve agreement and will be seeking appropriate funding to complete the inspections and the identified defects in the next regulatory period.

There have been a number of other practices and procedural improvements driven by changes in the regulatory environment, improvement in safety practices or general procedural improvements. It would appear these changes have been adopted as part of standard business practices.

The preparation for the 2015-2020 reset is resulting in some significant changes to some of the manuals and SA Power Network practices. The majority of these are in the areas of strategic asset and maintenance management. The manuals and associated strategies and practices are still under review and will feed into the reset submission
