6. Why incentives?  Mass legislature extended requirement of IOU electric efficiency programs until 2007  The 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 year  Cash incentives paid to reduce paybacks for projects that result in energy savings  Massachusetts Electric program’s started in the mid 80s and have been consistent leaders in paying out the incentive budget each year since
