  • New Yorks DG (/CHP) Incentives$15 Million SBC Funds through NYSERDAStandby Service Rates: CHP Exemptions and Phase-insStd. Interconnection Requirements (in Update)Electric Utility DG Pilot Program (Grid Upgrade vs. DG)DG Gas Distribution Prices + Gas Utility DG ProgramsState Education Dept Funding for K-12 SchoolsNYC EDC Energy Cost Savings ProgramElimination of flex-rate deterrent (in development)Air Emissions Standards (in development)Emissions Reduction Credits (in development)

  • NYSERDAs DG-CHP ProgramDevelop & Demonstrate Innovative DG Technologies & CHP ApplicationsSupport site-specific and sector wide feasibility studies and replicationMonitor Performance and Reduce Hurdles through Shared KnowledgeInstall Megawatts of Generation CapacityFunding: Cost share of 30 60% of Project cost subject to a cap of $1 million per project

  • Where Does DG/CHP Make SenseCapacity constrained-High electric demandsHigh thermal (steam, hot water, or direct heat) demandsCoincident thermal and electric demandsExtended operating hoursAccess to fuels (byproducts, natural gas)On Customer Side On Utility Side

  • 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.

  • New Yorks CHP Program SummarySupporting 96 demo projects, 50+ feasibility/Tech Trans. studiesNYSERDA funding of $47 million (in ~$220 M)27 Projects with a total installed capacity of 12 MW in operationExpect to reach 20 MW of capacity the end of 2004 (peak demand reduction of 26 MW)Additional capacities of 40 MW and 48 MW in 05 and 06, respectivelyCHP applications in industrial, agricultural, municipal, institutional, commercial, and residential sectorsField-Performance: Monitoring and Data Collection is Underway

    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%.
