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
