New England Generation Information System

• Nancy L. Seidman
• Massachusetts Department of Environmental
  Protection

2
New England-wide Benefits

• Enables efficient simultaneous demonstration of
  compliance with
• Environmental Performance Standard
• Information Disclosure
• Renewable Energy Portfolio Standard
• Each New England state has requirement(s)

What are the Functions of New Englands GIS?

• Load Serving Entity (LSE)
• Assist in compiling data to comply
• Generate reports for use by LSEs and regulatory
  agencies
• Generation
• Accounting for generation attributes and issuing
  Certificates to the owner of the asset
• Traders
• Identify and use common platform for generation
  attributes
• Regulatory Agencies
• Consistent Reporting
• Conserve generation attributes

GIS Working Group Process

• Effort began in 1998
• Necessary to have input from NEPOOL
  participants, ISO, contractors, environmental
  agencies and PUCs from all New England states no
  single party had all the answers
• Technical details build on previous efforts in US
• Policy issues not previously dealt with in such
  detail, or across so many agencies and
  jurisdictions
• Paying for GIS

5
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 EPS compliance
  demonstration in terms of pounds of pollutant/MWh

6
Pollutants Currently Covered by New England
Attribute Laws

• NOx
• SO2
• CO2
• CO
• PM
• Hg

7
Sources of Emissions Data

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

8
Regulatory Agencies Provide Ongoing GIS Support

• Work with adjacent control areas (NY, New
  Brunswick, Quebec)
• Approve methodology for multi-fueled units

9
Input still needed on

• Methodologies for pro-rating
• Cogen emissions electricity production
• Electric output and co-firing
• Emissions by fuel type for multi-fueled units
• Complex facilities to test methodologies

10
GIS Overview - Imports/Exports

• Imports/Exports - Unit Specific or System
• Unit Specific Information
• Eligible for RPS
• Adjacent Control Area
• Confirm energy was generated and flowed into NE
• Not otherwise sold
• Reserved Certificates
