Why incentives? Mass legislature extended requirement of IOU electric efficiency programs until 2007The charge of less than 3 mills/kwh for each commercial customer creates a pool of cash for incentives$millions are allocated to be spent in NE each yearCash incentives paid to reduce paybacks for projects that result in energy savingsMassachusetts Electric program’s started in the mid 80s and have been consistent leaders in paying out the incentive budget each year since

Prescriptive measures – lighting, motors, HVAC set incentivesCustom measures – cost benefit analysisRetrofit Program

MECO program - Energy Initiative40-45% of total cost or 2 year payback

New buildings, expansions, new loadMECO program - Design 2000+60-75% of incremental cost or 1.5 yr payback

Large CustomerMECO program – Accelerated Application ProcessEI – 1 year paybackD2+ - full incremental

Municipal programEI – 60%, customer net cost financed on electric billD2+ - full incremental

Industrial System Optimization ServiceLong payback measures may be able to split costs based on

percent savingsTechnical Assistance - contract with a third party engineering firm and share 50% of cost of TA study
