  1. New England Generation Information System Sharon Weber Massachusetts Department of Environmental Protection

  2. GIS Crucial to DEP • Restructuring Legislation MGL Ch. 111 Sec. 142N states DEP shall have in effect a generation performance standard (GPS) of emissions produced per unit of electrical output for at least one pollutant on May 1, 2003

  3. Compliance Determination • DEP receives emissions data, but not electrical output • ISO receives electrical output, but not emissions data • GIS will marry ISO electrical output to facility emissions data, to enable GPS compliance demonstration in terms of pounds of pollutant/MWh

  4. Ancillary Benefit • Enables efficient simultaneous demonstration of compliance with • DEP GPS, • DTE Information Disclosure, • DOER Renewable Energy Portfolio Standard, and • Equivalent attribute laws of all New England states

  5. GIS Working Group Process • Necessary to have input from: NEPOOL participants, ISO, APX, and environmental agencies and PUCs from all New England states: no single party had all the answers • Technical details could build on previous APX efforts in US • Policy issues not previously dealt with in such detail, or across so many agencies and jurisdictions

  6. Regulatory Agencies Will Provide Ongoing GIS Support • Supply adjacent control area (NY, New Brunswick, Quebec) average emissions to assign to system imports • Approve methodology for multi-fueled units that wish to be assigned single fuel certificates (called an “Approved Emissions Protocol” in the GIS Operating Rules)

  7. Plea for Input • Need to work up methodologies for pro-rating: • Cogen emissions to account only for electricity production • Electric output when co-firing with RPS-ineligible fuel • Emissions by fuel type for multi-fueled units that wish to be assigned single fuel certificates • Looking for complex facilities on which to test methodologies
