Funding • Low cost & no cost improvements • CT Energy Efficiency Fund • Fund up to 75% of project cost • $1 M / customer / year • Funding provided as a rebate after project completion • Funding currently available

Incentive Programs What’s eligible Prescriptive rebates (lighting/HVAC) Custom projects Pumps, aeration, VFDs, controls/automation Baseline data Calculating savings (k. W & $) Correspondence with utility

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 k. Wh savings or • $1, 000/ summer peak k. W 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 k. Wh savings or • $1, 100/ summer peak k. W savings • or – prescriptive $ per unit • Incentive may vary according to the application and Electric Company

Additional $ Caps (CL&P) • EO – $1, 000 annual cap per Federal Tax ID – http: //www. clp. com/downloads/Retrofit%20 Incentives. pdf? id=4294 986588&dl=t • ECB – $1, 000 annual cap per Federal Tax ID – Gas Projects require PURA approval > $100, 000 – http: //www. clp. com/downloads/ECB%20 Incentives. pdf? id=4294986 560&dl=t
