DG-CHP ChallengesRegional CHP Activity - Lack of similar CHP (/DG) interest among various statesStandby Rates - NYS PSC developed standby tariffs with CHP exemptions and phase-ins, other states like MA are in the process of developing tariffsEmissions 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 networksUtility Buy-In - Grid support, congestion mitigation, alternative to grid expansion/upgrade, utility ownership or access to excess capacity
Net MeteringNet 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 MeteringIn 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 kVA 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 kW enjoy net metering benefits also.

Picture here shows results from a GTI Study (John Kelley) done for Under Secretary Andrew Card. This study reviewed the impact of advanced technologies on the load shape for a typical light industrial/commercial circuit. Although a typical growth rate of 1.8% annually would indicate several years before needing to act this feeder was recently upgraded to 24 MW in anticipation of a new industrial park. Lowering utilization to 30%. What if the utility deployed DE instead? The results are dramatic. On peak only CHP eliminated the peak load while providing for substantial growth of the utility load. This approach brought the distribution circuit utilization to 60%.
