Is your utility looking at Smart Grid technologyholistically or do you look for point solutions

to solve specific problems?- Holistically

- Point solutions

Overview of US electricutilities


5/31


Statistics utilities are facing today

92% of all customer outages result from problems on thepower distribution system.

U.S. electric utilities spend about $18 billion per year ondiscovering root causes of outages.

The average age of a failed substation transformer is 18years with most transformers reaching 40 years of life.

U.S. loads will increase by 23% over the next 20 years.

Less than 10% of U.S. co-ops and municipal utilities havelaunched holistic smart grid initiatives.

Practical solutions for local utilities

A survey conducted last summer by GEIntelligent Platforms concluded thatsmall electric utilities were looking forsolutions to:

Reduce system outages

Enhance equipment lifecycles

Better manage customer loads

Digitize standard operating procedures

June 7, 2011

Reducing System Outages

SCADA systems for real-time view of your substations enabling you torespond remotely to reduce travel time and outage times.

Examples

Monitor and respond to substationoutages

Evaluate critical and non-critical

equipment alarms Research trends and determine

root causes of outages

Lifecycle Management

Develop predictive replacement strategies for substation transformers orrotating equipment, enabling utilities to eliminate downtime caused byfailures.

By understanding current status, youcan

Improve the lifecycle of your existingassets by knowing they are healthy,adding years of additional use toyour investments.

Plan for replacing equipment with

justification

Alarm Management

Receive real-time equipment alarms without having to wait for substation or

equipment inspections.

Have automatic action taken if desired

What is your utilitys response to load

management?

- None- Control of customers equipment (such as

residential water heaters)

- TOU pricing to let customers decide- Other

Load ManagementImproved information enabling you to more effectively predict and balancecustomer loads within wholesale and customer constraints.

Benefits

Know when to use control of

customer appliances/loads Forecasting of demand available for

reduction

Forecasting of rebound effect

Create consistency in use of controls Manage all constraints related to

wholesale and load management

Knowledge Management

Make your newest operators as knowledgeable as your best operators byinstitutionalizing standard operating procedures (SOPs).

Benefits

Combating the brain drain that occurs whenknowledgeable employees retire

Improving your overall process reliability

Documenting compliance with standard proceduresand regulations

Examples of SOPs that can beautomated

Switching procedures

Equipment troubleshooting

Outage troubleshooting

Open & Layered softwarearchitectureWhen specifying software, look foropen architecture.

Know the platform of the solution(Windows vs Linux/Unix and thecosts of supporting this in terms of $,training and people)

Be wary of proprietarysoftware/hardware

Determine if software can connect tobasic systems, RTUs and relays

Can additional solutions be added oneasily?

Can it support CIP requirements?

Do you evaluate software solutionpurchases through a total cost ofownership model including: initial

cost, anticipated upgrade costs,and annual maintenance contract

costs?- Yes- No

grid

Develop your own roadmap of where you want to be Think about flexibility, holistic, long-term and integrated approach

Watch out for point solutions that solve the immediate need but cant grow

Determine if the supplier will be there for you in 10 years

Determine any issues with your purchasing policies based on integration

requirements or add-ons from suppliers Use total cost of ownership as your comparison metric (ask for hourly prices and

see how expensive adding a new sub will be)

Be realistic about your staffs time and ability to install SCADA at a substation

after the vendor does one substation and trains your staff
