Presentation Transcript

  1. New England Generation Information System Nancy L. Seidman Division Director Massachusetts Department of Environmental Protection

  2. GIS benefits Agencies • Enables efficient simultaneous demonstration of compliance with • DTE Information Disclosure • DOER Renewable Portfolio Standard • DEP GPS (if implemented) • Equivalent attribute laws of all New England states

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

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

  5. Pollutants Currently Tracked in GIS • CO2 • CO • Hg • NOx • PM • PM10 • SO2 • VOCs

  6. Emissions Data Hierarchy • CEMS • Emissions data reported to state or local agency (typically annually or triennially) • Stack testing data • Emission factors

  7. Regulatory Agencies Provide GIS Support • Supply adjacent control area (NY, New Brunswick, Quebec) average emissions to assign to system imports • Supply default worst-case emissions to be assigned to non-reporting units • Approve methodologies for multi-fueled units that wish to be assigned single fuel certificates (“Approved Emissions Protocol” in the GIS Operating Rules)

  8. Additional Emissions Detail • Cogen units required to report emissions associated with electricity generation, not steam • Non-reporting units assigned a default worst-case emissions/MWh by fuel • Non-reporting Multi-fueled unit assigned emissions of fuel with highest CO2

  9. Next Steps • Work with NY ISO & PJM to provide consistent system across RGGI region • Update GIS operating rules • Provide consistent review of QA’d emissions data • Review systems beyond borders of NE ISO to update or establish imported power attributes
