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

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

4. Public Benefits Charge

5. 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

6. 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

7. 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

8. 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

9. 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

10. 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

11. Additional $ Caps (CL&P) • EO • $1,000,000 annual cap per Federal Tax ID • http://www.cl-p.com/downloads/Retrofit%20Incentives.pdf?id=4294986588&dl=t • ECB • $1,000,000 annual cap per Federal Tax ID • Gas Projects require PURA approval > $100,000 • http://www.cl-p.com/downloads/ECB%20Incentives.pdf?id=4294986560&dl=t

12. Pumping Project Example • Pump System Improvements • VFDs • PLC control system • Instrumentation • WW level, pressure & flow, kW • Discharge flow & pressure • Online pump efficiency monitoring • Optimized pumping controls • 50% Incentive (total installed cost) • $150,000 (EO)

13. Aeration System • Process modification • Dissolved Oxygen controls • New instrumentation - Air flow meters & air flow control valves • New blower VFDs • PLC control panel • Expected savings = > 1 million kWh/yr • Incentive funding $270,000 (EO)

14. Pumping Project Example • Pump System Improvements (oversized pump replacement) • Incentive: $19,950 (ECB)

15. Aeration System – Blowers & Controls • New Blowers • High Efficiency units selected instead of standard design/models • Enhanced controls also installed • Dissolved Oxygen control • Air flow meters & flow control valves • PLC control panel • Expected savings = > 1 million kWh/yr • Incentive funding $900,000 (EO & ECB)

16. Wastewater Plant Upgrade • Multiple measures – part of substantial facility upgrade • Pump improvements – VFDs & controls • New Blowers – aeration system • Expected savings = > 1 million kWh/yr • Incentive funding $480,000 (EO & ECB)
