16

Reasonableness Tests

• ATC will assess factors including, but not limited to:– Distance from generator to existing ATC

system– Application of general least cost planning

principles– Point-to-point revenue to annual revenue

requirement comparison

17

Eligibility Requirements

• Financial screening of generating firm

• Guarantee to cover ATC costs expended if project fails or does not proceed as planned

• Executed interconnection agreement

18

Policy Subject to Change

• Policy may be changed at some time in the future as generation becomes more plentiful, system configuration changes, RTO congestion management systems are implemented or other relevant conditions occur.

19

Overview of Generator Interconnection Process

Teresa Mogensen

Director of Transmission Planning and Service

20

Multiple Processes Leading to Licensing

• Interconnection Study Process is the most visible; however, it is not the only process to consider

• In order to be able to produce a regulatory filing after the formed study process is complete, there are additional associated processes to follow

• Some steps can run in parallel; some must be done in a particular order

21

Multiple Processes

• Planning Interconnection Studies

• Detailed Design & Cost Estimating

• Interconnection Agreement

• Regulatory

• Siting

• Transmission Service

22

Planning Interconnection Studies

• Determines impact of proposed new generation or modifications to existing generation on transmission system

• Identifies and classifies necessary facilities– Interconnection facilities– Required system upgrades– Optional system upgrades

23

Detailed Design and Cost Estimating

• Standards and Specifications

• Construction Plans

• Design Basis Manual for Project

• Details needed for interconnection agreement and regulatory application

24

Interconnection Agreement

• Formalization of relationships and responsibilities– Physical interconnection details– Construction schedules– Ongoing operations– Legal obligations and responsibilities– Financial commitments and qualifications

25

Regulatory

• Application for generation requires associated application for transmission

• Specific timelines and milestones– Notice and information – Public meetings– Filing steps

26

Siting

• Hand-in-hand with regulatory

• Constructablity assessment

• Work with public to find the most acceptable routes – Public planning process– Inform and involve local officials and

government representatives

27

Transmission Service

• Separate process/request/queue than for Interconnection Service

• Interconnection Service– Provides rights to physically interconnect to

transmission system– No rights to move power

• Transmission Service– “Delivery Service”– Provides rights to move power

28

Working Together• ATC wants to facilitate successful projects

and relationships with our customers

• Resolution of backlog is underway

• Keep us involved and informed as you initiate and proceed with your project

• We want to work together with you for most efficient and effective use of our mutual resources!

Submitting the Request

• How can you submit the form:– Fax to phone number on the form– Delivery to address on the form

• Receipt of request establishes queue position• Customer must deliver the original, signed form to

address on form for the request to be valid, so– If initially faxed, the original form must be received

within 10 calendar days of the fax transmittal to retain queue position

– If not received within 10 calendar days, receipt of original form will establish a new queue date

41

What Will ATC Do With Request?

• Add the request information to the queue

• Post the revised public queue within 2 business days

• Confirm receipt of original form, when received, with customer and communicate queue position

• Begin preparing Study Agreement

42

Before the “Study”

• Customer needs to execute a Generator Interconnection Study Agreement

• Generic version of agreement is available on the OASIS

• ATC will tender the agreement within 30 calendar days of the request

• Customer has 15 days to execute

43

The Study Agreement

• States what the deliverables are:– Identification of three types facilities related to

the requested service• Interconnection Facilities – equipment needed to

make the physical connection

• Required System Upgrades – equipment needed to resolve stability or short circuit “problems”

• Optional System Upgrades – essentially equipment required due to thermal overloads

– Cost estimate for these facilities

44

The Study Agreement

• States the cost estimate to perform the study and the time frame expected for completion of the study

• ATC may revise the cost estimate and time frame as the study progresses

• Customer may cancel study at any time• ATC may only charge actual cost of the

study incurred up to completion or cancellation

45

The Study Agreement

• What does the customer need to supply?– One-line of the proposed interconnection to the

transmission system, including a substation diagram showing bus configuration with breaker positions

– Generator machine and step-up transformer data plus exciter and governor models

• Changes to this information may require a re-evaluation of the request

• Customer then submits the executed agreement

46

The Study Agreement – Data

47

Changes to a Request

• Once a request is made, certain changes will require the customer to submit a new request for interconnection:– Change in generator’s location if it results in a

different connection configuration– Earlier in-service date– Significant change in generator’s output –

ATC’s engineering judgment

48

The “Study”

• Four types of analysis may be required:– Stability– Short circuit– Thermal– Voltage (not typically required)

• Data provided is critical for the proper evaluation of interconnection request

• Not a Transmission Service Request study

49

The “Study” – Step 1 – Setup

• Development of ATC one-line from customer’s submittal

• ATC identifiesstudy scenarios

• Identification ofthe InterconnectionFacilities can begin– Equipment in black

The “Study” – Step 2 – Stability

• Stability Analysis– Transient and Dynamic Stability Examined

• The system is analyzed with the addition of:– The proposed generation

– Any competing request earlier in the queue

– Transmission projects with internal approval but do not require a CPCN or acquisition of significant ROW

• Output of new units is delivered in the reverse of the CBM directions (75% to CE, 25% to MAPP)

51


• Determine Critical Clearing Time (CCT) for– 3 Phase fault with system intact

– 3 Phase fault with prior outage of one element

• CCT is the longest time the fault can be applied to the system before unit instability occurs

• CCT must be at least 1 cycle longer than the total breaker clearing time to be acceptable– Applies to both the primary and backup clearing

scenarios

52


• If find instability, what can be proposed?– Need for high speed circuit breakers and relaying (e.g.,

2 cycle breaker operating time)

– Direct tripping of unit(s)

– Operating restrictions (e.g., no operation below 50% system peak load)

– Transmission line or transformer additions/changes

• Equipment identified in Stability Analysis falls into Required System Upgrades

53

The “Study” – Step 3 – Report

• Provide an interim report on the findings from the Stability Analysis

• Interim report will include– Interconnection Facilities identified– Required System Upgrades identified– Rough cost estimates of the above equipment– Operating restrictions identified

• Notation made on OASIS so other customers may request a copy of this report

54

The “Study” – Step 4

• Two analyses in parallel plus refinement of the initial cost estimates– Short circuit study– Thermal study – not related to transmission

service request– Engineering revises the cost estimates for

Interconnection Facilities and Required System Upgrades identified in Step 2

55

The “Study” – Short Circuit

• The system is analyzed with the following components:– Same system as Stability Analysis plus– Required System Upgrades from Stability

• Primarily an issue of circuit breaker overduty – examine before and after

• Any equipment identified is listed as a Required System Upgrade

56

The “Study” – Thermal

• The system is analyzed with the following components:– Same system as Stability Analysis plus– Required System Upgrades from Stability

• Output of new unit is delivered to increasing load within the ATC system

• Units in surrounding area are set to maximum output to stress local system

57

The “Study” – Thermal

• Only identify transmission elements with a distribution factor 3%– That is, at least 3% of the output of the unit

must flow on that particular element– Consistent with MAIN methodology for

transmission service requests

• Any upgrades identified are Optional System Upgrades

58


• Short Circuit analysis is rerun:– Same system as initial Short Circuit plus– Optional System Upgrades

• Any equipment identified now is listed as an Optional System Upgrade

59


• Stability Analysis may need to be rerun depending on Optional System Upgrades identified

• If Stability Analysis must be rerun, more Optional System Upgrades may be identified

• Basic message – The study is often an iterative process

60

The “Study” – Step 6 – Final

• Conceptual Design is created showing various equipment additions

• Engineering produces final cost estimates:– Interconnection Facilities– Required System Upgrades– Optional System Upgrades

• First two categories of equipment must be built for interconnection to occur

61

Final Report

• Final Report is issued to customer following notation on the OASIS that the study is complete

• Other customers may request a copy of the report issued– Good way to find out issues for a particular

area of interest

62

Final Report

• What will the final report contain?– Summary report of the various analyses– Sub reports as attachments for each analysis

• Important points:– If generator data changes as project moves

ahead, a re-examination of site may be required– Any operating restrictions will be revisited by

ATC as network additions occur

63

Now What?

• Final Report is delivered to internal team

• Hand-off occurs to Interconnection Agreement Process

• Transmission Service Request, if any submitted, will be studied

• Billing will occur

64

Consultants

• ATC continues to review using consultants to perform studies– Consultant will be paid for by customer– Consultant will coordinate with ATC– Consultant will report results to ATC and ATC

will then communicate results using previously described process after posting note on OASIS

65

Helpful Hints

• Interconnection Request Transmission Service Request

• Make a request that covers the possible unit configurations (e.g., if up to 5 units, then request a study with those increments)– ATC will determine if the request should be split into

different studies and will communicate that to customer

– Make separate requests if considering multiple unit types (e.g., GE 7FAs vs. GE 7FBs)

– Still need to supply one-line and data for each scenario

66

Helpful Hints

• If siting in Wisconsin, go to the Public Service Commission (PSCW) website:– http://www.psc.state.wi.us/default.htm– OASIS has links to the following PSCW documents:

• Requirements for Power Plant and Power Line Development• Electric Power Plants: Approval Process • Construction and Environmental Information Overviews

• If siting in Michigan, visit Michigan Public Service Commission (MPSC) website:– http://www.cis.state.mi.us/mpsc/electric/

• Above links available on the OASIS

http://www.psc.state.wi.us/default.htm

http://www.cis.state.mi.us/mpsc/electric/

67

Helpful Hints

• For Wisconsin, Alternate Sites for CPCN:– PSCW requires at least one alternate site– Submit one request to ATC for each of the sites

you intend to submit to the PSCW– ATC will determine if more than one study is

required– Key issue: electrical equivalence for each part

of analysis

68

Helpful Hints

• Customers can request study criteria, methodology and base cases– Allows customer to use a consultant to pre-

screen sites– Provides a common basis to understand the

analysis ATC performs– Base cases will not include generation requests

in the queue – customer will need to determine what to include from publicly available info

69

Final Comments

• Desire feedback from the customer on the study process. ATC wants to know:– What worked and what didn’t– What information was hard to find– What could have been done differently– What information was not clearly

communicated– Anything else you think we need to know

70

The Regulatory and Siting Processes

Pete Holtz Manager - Siting

71

Interaction With Wisconsin State Agencies

• CPCN required for power plants >100 mw and for associated transmission lines

• Generation and transmission components should be filed as a single joint application

• WDNR must issue construction and operating permits

• WDNR air emissions permits required prior to CPCN

72

Project Approval Process

• DNR Engineering Plan – 60 days prior to CPCN application

• Public Information Meetings – 30-60 days prior to CPCN application

• PSCW Completeness determination – 30 days

• Deadline on order issuance – 180 days from completeness determination

73

Regulatory Summary

• Contact the PSCW and WDNR and ATC early in a project’s siting process

• Establish relationship with agencies and with ATC

• Learn how the project approval process works

• ATC goal is to work with you to meet regulatory requirements of the project

74

Goal of Siting Process

• Connect Point A with Point B

• Weigh multiple factors

• Balance the Technical with the Feasible

75

Siting Realities

• Takes more time and are more difficult• Difficult to obtain 100% acceptance• Changing public attitudes• Desire for more control and choices• Media coverage• Easy to organize and obtain information• Political responsiveness

»

76

Success Includes Recognition

• Each Project is unique

• Involve of local officials early in the process

• Involve public in the process in a structured manner

• Continuous communication to all parties

• Need for flexibility

77

Siting - Coordination

• Internal: Real Estate, Engineering, Environmental, Planning, Construction, Communications and Regulatory areas

• External: Public, Government Officials (at all levels), Media, Key Organizations and other identified Stakeholders

78

Public Involvement

• Purpose is to provide information, obtain information, respond to concerns and listen

• Proactive• Early in the project timeline – prior to

formal filings• Involve Public, Government Officials at all

levels, key stakeholders, regulators• Many ways to be involved in the planning

process

79

Transmission Service Requests (TSRs)

Dale Burmester Manager Transmission Services

80

Transmission Service Requests (TSRs)

• TSR is required before you can “move” any MWs• All TSRs are made via the OASIS• ATC OASIS node is located at:

oasis.maininc.org/OASIS/ATC• TradeWave certificate is required to make requests

and query offerings, but not to view information• Mid-America Interconnected Network (MAIN)

operates the OASIS node, calculates transfer capability and posts ATC/TTC and offerings

81

TSR Tips and Helpful Hints

• Point-to-point Transmission Service (PTS) is used to move power off the ATC transmission system

• Network Transmission Service (NTS) is used to move power to ATC network customer load– NTS must be requested by the network customer– To prevent “hoarding”, there are special rules for NTS

• ATC OASIS Business Practices & Policies:oasis.maininc.org/documents/ATC/practices.html– Converting POD (also POR, source, and /or sink)– Rollover rights

82

TSR Expectations

• Requests beyond 13 month posting horizon: 60 days or longer for “System Impact Study” and/or “Facility Study”– Special evaluation is required, since there are no MAIN

studies available– At this time, typical study completion dates are projected

to be within 60 days.• This can and will change if/when the queue gets larger

– TSR study process begins after Generator Interconnection Study is complete

• “Optional” upgrades from GIS will likely become required to grant the TSR

– All TSRs need to be processed in queue order

83

Recent MISO/RTO Developments


84

Acronyms

• MISO: Midwest Independent System Operator

• ARTO: Alliance Regional Transmission Organization

• IRCA: Inter RTO Coordination Agreement

85

Midwestern RTO Territories

86

IRCA History

• FERC goal for RTO development was to minimize border issues and ultimately create a seamless market

• Illinois companies petitioned FERC to leave MISO and join ARTO

• With Illinois companies’ departure, resultant Midwestern RTO territories are less than cohesive

87

IRCA History

• Settlement negotiations between MISO and ARTO were ordered by FERC to address seams issues and ongoing relationships

• Goal was to develop a “super region” such that the two RTOs would look like one to market participants

– RTOs decided to work toward common rate and procedures

• Result was Inter RTO Coordination Agreement between MISO and ARTO

88

IRCA

• 22 issue areas are to be addressed

• Plans to address each area must be negotiated between MISO and ARTO and submitted to FERC for approval

• Teams of MISO representatives, MISO TO representatives and Alliance representatives are working on each area

• Most of the resulting processes must be up and running by end of 2001

89

Joint Generation Interconnection Agreement

• IRCA Article 9 mandates development of a “common” interconnection agreement and procedures

• Developing interpretation of “common” is “same base principles” rather than “identical”

• Allows for differences in business and ownership structures between ARTO and MISO

90

Existing IAs vs. New Ones

• If generator had a recently negotiated agreement with an independent transmission company (i.e. ATC) we are working towards being able to “grandfather” the agreement with ARTO/MISO– Plus execute a “bridge agreement” to recognize ISO

operating authority

• If generator does not have such an agreement reflecting “today’s world”, a new one will need to be negotiated

91

Common IA Development –Key Dates

• Updated draft to be issued June 1

• Joint MISO/ARTO Stakeholder meeting in Chicago June 7 thru June 8

• Final version to be issued June 29

92

Opportunities for Input

• Watch web sites for announcements of ISO stakeholder meetings or comment opportunities:– http://www.midwestiso.com/– http://www.atcllc.com/– http://www.alliancerto.com

• Provide your input to ATC or RTO staffs

Generation Interconnection – Operating Issues

Don Morrow

Director of System Operations

94

Operating Issues

• Redispatch

• Emergencies

• Data Collection and Communications

• Metering

• Operational Control

• Maintenance Scheduling Process

• Blackstart

95

Redispatch

• What is Redispatch? Generation that needs to be adjusted to

ensure the reliable operation of the transmission system.

• ATC will redispatch to preserve Network Transmission Service (Attachment K to ATC’s OATT)

96

Redispatch - cont

• Section 3.6a of GTIA establishes the right of ATC to call on a Generator for Redispatch to maintain Network Security

• Section 3.6b of GTIA establishes compensation as the incremental cost incurred to perform the redispatch

97

Emergencies

• Imminent threat to life or significant threat to health, property or the environment

• ATC has right to reduce output or curtail under an emergency

• Generator has right to operate inter-connection facilities under an emergency

98

Data Collection

• Important for the safe and reliable operation of the Transmission System

• Instantaneous MW, MVAR, voltage and current

• Device status such as breakers, MOD, etc.

99

Data - cont

• Generator responsible for the collection and dissemination to the ATC

• GTIA allows for this to come from Distributed Control Area Operator

100

Communications

• Generator to provide:

Voice communications with ATC system operators

RTU and data communications of mutually acceptable bandwidth to collect the data from the field

101

Communications - Cont

• Data may be distributed to ATC by ICCP or other industry standard protocol

• Completed before operation of Generator

102

Metering

• Generator owns, operates, tests and maintains Revenue Quality Metering System

• Bi-directional Real and Reactive Power

• ATC has rights to request meter tests

103

Operational Control


Line 3

Line 4 Line 5

Line 1Line 2

104

Operational Control - Cont

• ATC needs to have operational control over switch regardless of ownership

• Concern is something connecting to system without ATC being aware of it

105

Operational Control - Cont

• Generator needs to communicate anyway to ensure protection of its equipment

• ATC needs to agree to opening and closing the switch

• How to ensure? ATC operate? Tag in ATC name? Discuss

106

Maintenance Process

• Mutually agreeable maintenance scheduling

• Party doing schedule to use good faith to find a mutually acceptable time period

• ATC concern is transmission system reliability

107

Maintenance - Cont

• Generator to give a rolling 24 month outlook for planned outages

• ATC has one month to review and work out alternatives w/ generator if necessary

• Applies to units10 MWs or greater and interconnection facilities

108

Maintenance - Cont

• Changes allowed if mutually agreed

• Finalization of maintenance schedules is by mutual agreement.

• If can’t be agreed upon, ATC has right to set schedule if it feels reliability is in jeopardy. ADR is backstop.

109

Black Start

• No requirement for black start in GTIA

• Essentially a Network Resource issue since Black Start Capability is addressed in the Network Operating Agreement

• ATC needs to ensure sufficient capability to restart the grid.
