A Key Challenge for Renewables

• Capturing the environmental value
• GIS
• Creates platform for monetization of the
  environmental value
• Facilitates the ability of renewables generators
  to access an additional revenue stream or green
  premium

3
In Addition the GIS

• Broadens market base for renewable generators
• Facilitates green power markets
• Allows large generators to access premium outside
  wholesale market
• Offers particular benefits for intermittent and
  small and behind the meter generation

4
Small and Behind the Meter Generation

• GIS relies mainly on ISO MSS for generation data
• However, ISO MSS does not capture data on most
  generators lt 5 MW
• GIS will accommodate small and behind the meter
  generators

5
Treatment of Small and BTM Resources

• Non-NEPOOL Generators
• generating units with a nameplate capacity of 5
  MW or less and do not provide separately metered
  data to the MSS can submit data for the creation
  of certificates
• Non-NEPOOL Generator Representatives
• Allows for aggregation of small generation
• Can effectively bank generation from month to
  month
• Data must be submitted 5 days before creation of
  certificates in each quarter

6
Metering and Communication

• Metering based on current NEPOOL Operating
  Procedure
• Requires standard utility revenue-grade meter
• Must record Wh, KWh, or MWh output
• Must conform to ANSI standards
• Generators can submit data
• Electronically directly to GIS
• Manually or electronically to aggregator

7
Issues/Opportunities

• Need for compatible systems across pools
• Additional benefits for renewable generators if
  GIS or GIS-like system is adopted at a
  regional/national level
• FERC SMD and NERTO
