Where Does DG/CHP Make Sense On Customer Side • Capacity constrained. High electric demands Where Does DG/CHP Make Sense On Customer Side • Capacity constrained. High electric demands • High thermal (steam, hot water, or direct heat) demands • Coincident thermal and electric demands • • Extended operating hours Access to fuels (byproducts, natural gas) On Utility Side 30% CHP – On Peak Only Operation Grid Capacity Utilized at 60%

DG-CHP Challenges • • • Regional CHP Activity - Lack of similar CHP (/DG) DG-CHP Challenges • • • Regional CHP Activity - Lack of similar CHP (/DG) interest among various states Standby Rates - NYS PSC developed standby tariffs with CHP exemptions and phase-ins, other states like MA are in the process of developing tariffs Emissions Standard - NYS DEC is in the process of developing air emissions standards. Others ? Interconnection – NYS is in the process of updating its SIR to 1 MW and to networks Utility Buy-In - Grid support, congestion mitigation, alternative to grid expansion/upgrade, utility ownership or access to excess capacity

Net Metering • Net metering turns the electric meter backwards when the DG is Net Metering • Net metering turns the electric meter backwards when the DG is producing energy in excess of the demand. • Enables the use DG to offset consumption over a billing period. • Customers receive retail prices for the electricity produced and used onsite. • Without net metering, a separate meter measures electricity that flows back to the utility typically at a wholesale price that is much lower than the retail rate.

Net Metering • In 2002, Governor Pataki signed a farm net metering law that Net Metering • In 2002, Governor Pataki signed a farm net metering law that required utilities to provide net metering to farms that generate electricity from methane wastes. – 400 k. VA or smaller, 80% methane waste, on farm-uses – typical farmer can save about $6, 000 a year in energy costs • Residential PV systems smaller than 10 k. W enjoy net metering benefits also.
