Public Benefits Charge

What is the Program?

• Connecticut Energy Efficiency Fund (CEEF)– 3 mill charge on all electric and gas bills– CL&P and UI Administer the Fund Electric

Programs– CL&P Administers the Fund Gas Programs

• Incentives to Do the Right Design– Provides funds to promote use of energy saving

designs and equipment

The Big Picture

• Gas and Electric Projects Eligible• EO - Energy Opportunities– For existing process equipment that are within

design life• ECB - Energy Conscious Blueprint– For new designs – For replacement of process equipment beyond

design life

EO Projects

• Additions to existing equipment that will save energy– VFD on motors– Air Receiver tanks that allow lower pressure– Energy efficient lights– Automated Process controls– Software to shut down unused computers– Will need savings calculations

EO Project Incentives (CL&P)

ECB Projects

• New Design/ Equipment or Replacement of Equipment > 75% Useful Life– Compare energy efficient equipment to base non

energy efficient equipment– Will need $ for base and efficient equipment– Will need calculations for savings

ECB Project Incentives (CL&P)

Additional $ Caps (CL&P)

• EO– $1,000,000 annual cap per Federal Tax ID– http://www.cl-p.com/downloads/Retrofit
