Why incentives

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

Conservation incentive programs

Conservation Incentive Programs

  • Prescriptive measures – lighting, motors, HVAC set incentives

  • Custom measures – cost benefit analysis

  • Retrofit Program

    • MECO program - Energy Initiative

    • 40-45% of total cost or 2 year payback

  • New buildings, expansions, new load

    • MECO program - Design 2000+

    • 60-75% of incremental cost or 1.5 yr payback

  • Large Customer

    • MECO program – Accelerated Application Process

    • EI – 1 year payback

    • D2+ - full incremental

  • Municipal program

    • EI – 60%, customer net cost financed on electric bill

    • D2+ - full incremental

  • Industrial System Optimization Service

    • Long payback measures may be able to split costs based on percent savings

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


Action plan for efficiency upgrades

Action plan for efficiency upgrades

  • Compare your facility to others

  • Inventory all equipment

  • Develop a measure list

  • Prepare estimates of cost and savings

  • Third party review

  • Secure funding/allocate budget

  • Implement with oversight

  • Commission by third party

  • TA funds from local util may cover portion
