  1. NARUC Summer Meeting ENERGY RESOURCES & ENVIRONMENT COMMITTEE Marriott Marquis New York City July 16, 2007 Off-Peak Cooling with Thermal Energy Storage (TES)

  2. Off-Peak Cooling with Thermal Energy Storage (TES):An energy efficient technology to reduce peak electricity demand, operating costs, and NOx & CO2 emissions. • Moderator:The Hon. Clifton C. Below,New Hampshire Public Utilities Commission • Mark MacCracken,CEO, CALMAC Mfg. Corp. • Greg Tropsa, President, ICE-Energy, Inc. • Chris Smith, Peak Load Reduction Program Manager, NYSERDA (NY State Energy Research & Development Authority)

  3. Summer Peak is growing faster than Winter or Load CB p. 1

  4. Load Factors (asset utilization rates) are declining ISO-NE Summer Peak Load FactorsHistory 1980-2006, Forecast 2007-2016 68% 60% 52% From ISO-NE, 2007 CELT (Capacity, Energy, Loads and Transmission) and RSP (Regional System Plan) Forecast CB p. 2

  5. A large portion of peak demand (summer A/C driven) is for relatively few hours CB p. 3

  6. Generation capacity to meet summer peaks is run (and paid for) for few hours CB p. 4

  7. Even on the hottest and highest peak days, demand (and prices) drop at night Record Peak CB p. 5

  8. Daily temperature NOx Emissions and High Electricity Demand Days (HEDD)

  9. High Electricity Demand Days:The Environmental Opportunity • Seasonal or annual NOx trading control programs do not address the problem • Demand for electricity is increasing and the increase in the peak is growing faster than the base: • PJM Interconnection: consumer peak demand for electricity will rise ~ 1.6% annually over the next decade. • NE ISO: peak demand will rise ~2.4% annually. • NYISO: relies heavily on many combustion turbines to maintain NYC grid. →Reductions of NOx on peak days will provide significant ozone reduction benefit
