Utility Goals in Support of EO1

Create/ensure Agency understanding of utility

energy efficiency resources

– Incentives, technical expertise, financing, etc.

Integrate utility process with State’s project

approval process to streamline delivery and

make energy efficiency part of business as

usual!

– Identify potential projects and develop joint strategy

for prioritizing work

Tailor services based on usage and market segments

Encourage focus on multiple end uses and fuels

Promote best practices through:

Energy Efficiency Program Strategies

Education– Benchmarking

– Case Studies

Incentives– Installing New

Equipment

– Retrofitting Existing Equipment

Financing– On-bill for some

programs

– Low or no interest
