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) Lesser of – 40% of installed cost or – Greater of $0.35/annual kWh savings or $1,000/ summer peak kW savings or – $500 / point for Energy Management System or – prescriptive $ per unit

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) Lesser of – 75% of incremental (base vs efficient) cost or – Greater of $0.50/annual kWh savings or $1,100/ summer peak kW savings or – prescriptive $ per unit Incentive may vary according to the application and Electric Company

Additional $ Caps (CL&P) EO – $1,000,000 annual cap per Federal Tax ID – p.com/downloads/Retrofit%20Incentives.pdf?id= &dl=t ECB – $1,000,000 annual cap per Federal Tax ID – Gas Projects require PURA approval > $100,000 – p.com/downloads/ECB%20Incentives.pdf?id= &dl=t
