RENEWABLE ENERGY LEADERSHIP SUMMIT 2005 AN OVERVIEW OF UTILITY EFFICIENCY PROGRAMS
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 • 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 • 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
Pumping Efficiency Measures • Reduce load • Manage load • Water to wire efficiency • Pump selection • Motor and drive selection • Automated control
Waste Water Aeration Measures • Fine bubble • Improved surface aerators • Premium motors • High efficiency motor drive • Blower vfds and • Automatic DO control
Lighting efficiency measures • T5 low and high bay fixtures • Pulse start Metal halide • Indirect fluorescent • Super efficient T8s • Comprehensive controls for large buildings
HVAC efficiency measures • Water source heat pumps • Prescriptive incentives for RTUs • Custom incentives for larger units • Low volume fume hood • Occupancy controls • Heat pump for generator oil sump
