Who Is Oncor?


Oncor is Texas's largest

regulated electric delivery

business in Texas

Oncor supplies electricity to

approximately 10 million

consumers in a service area

of over 400 communities

Operates in the U.S.'s

highest-growth region in

electric demand, according

to the North American

Electric Reliability Council


Deregulation in Texas & Oncor







Why Energy Efficiency?

1. Energy efficiency is deemed to be one of the most cost effective

sources of energy.

The cost of saving a kW or kWh is less than the cost of producing a kW

or kWh (cost effectiveness)

2. In past years, the electricity generation capacity during peak times

has not always met the demand.

3. Energy efficiency programs help create demand and supply of new

technologies to encourage early adoption.

4. Energy efficiency programs spur changes in new building codes as

technologies become more readily available and affordable.


Demand and Energy SavingsWhere do they come from?

To achieve the energy and demand goals,

Oncor offers Energy Efficiency Programs.

Programs offer incentives to install equipment (measures) or

have services performed that increase the efficiency of a

home or building

Incentives cover a portion of the cost of the project

Incentives are based on the actual demand and energy

savings as a result of the work ($/kW and $/kWh saved)

Most incentives are paid to participating service providers

who then pass the discount ($) onto customers


How to Become a Service Provider

& Participation Process



EEPM is Oncors Web-based project management system. It allows

users to:

Manage their profile with Oncor

Submit projects for incentives

Check the status of projects

Calculate incentives and savings

Find additional resources such as program manuals, savings

calculations (deemed savings) and other program materials

Visit oncoreepm.com and complete an Umbrella Agreement.

Glossary of Terms


Glossary of Terms Calculating Savings

Peak Demand: The electric demand that occurs during peak summer or

winter hours (excluding holidays)

Summer: M-F, 1-7 PM from June 1st September 30th

Winter: 6-10 am & 6-10 pm from December 1st February 28th





Coincidence Factor:

The fraction of load

reduction resulting

from a measure that

coincides with the

peak period. Typically

shown as a %.




Glossary of Terms Calculating Savings

Measurement and Verification (M&V): The process of verifying and

measuring the actual energy and demand savings as the result of an

energy efficiency project. This can include metering or logging of data

and engineering calculations.

Deemed Savings: An estimate of energy or demand savings for a

measure that has been developed from actual data and analytical

methods to create stipulated values. Deemed savings may be used

in specific applications in lieu of measurement and verification


E-Files: A set of Excel-based spreadsheets that incorporate deemed

savings information used to calculate energy and demand savings

based on specific input criteria.


Glossary of Terms Forms and Tools

Fixture Codes: A code provided to denote a specific lighting fixture in the E1 Lighting File.

Program Manuals: Document that incorporate all the program rules, processes, incentives, budgets, and program contact information.

Phases of Participation:

Initial Application (IA): Blocks incentive funds for a project for a specified period of time.

Final Application (FA): Provides accurate project information used to generate a formal Reservation of Funds Agreement.

Installation Notice (IN): Period of time for construction and notification to Oncor of completion.

Savings Report (SR): Generation of the

project savings and incentives.


Glossary of Terms Program Evaluation

Estimated Useful Life (EUL): The estimated time (typically in years) that a measure continues in operation.

Cost Effectiveness: The value of the savings generated by a program or measure versus the cost.

Evaluation or EM&V: The process of an outside, third party (hired by the PUCT) conducting verification activities on utility administered programs.

Opt Out: A customer or customer class that has

elected not to contribute to the Energy

Efficiency Cost Recovery Fund. These

Customers are NOT eligible for participation.

Commercial Energy Efficiency Programs

Oncors Commercial Energy Efficiency Programs provide incentives for

upgrading equipment and processes to increase the energy efficiency of a

facility. Commercial facilities have the opportunity to select from two

participation pathways.

Basic Commercial Standard Offer Program

Incentives available for new or existing facilities

Project savings determined using deemed savings

Custom Commercial Standard Offer Program

Projects with measurement and verification requirements and an incentive of $10,000 or more

Types of Projects:

Residential Energy Efficiency Programs

The Home Energy Efficiency (HEE) Program and Low Income Weatherization Program (LIW) offer incentives to service providers who implement qualifying peak demand and/or energy saving projects for eligible Oncor residential customers.

Home Energy Efficiency

HEE Program has two options: Main and Multifamily

Service Providers enroll in the program at the beginning of the year and receive incentives for completed projects

Customers may incur some cost as negotiated with their Service Provider

Low Income Weatherization

The LIW Program offers incentives to Service Providers who implement qualifying peak demand and/or energy saving projects for residential customers with income levels at or below 200 percent above the federal poverty guidelines

Services are typically performed at no-cost to customers

Types of Projects:

Solar Programs

Financial incentives are offered to Service Providers for the installation of

eligible distributed solar energy photovoltaic generating equipment

Available to Oncor residential and commercial customers (incentives paid

to Service Providers)

Approximate incentive using deemed savings calculation method:

Residential: $1.09 per DC Watt (at Standard Test Conditions (STC)

Commercial: $1.09 per DC Watt (STC)


Average Project Incentives:

Residential: $8,363

Commercial: $41,442
