2. New England’s Renewable Requirements to Double Over the Next Decade
Planning process must accommodate new needs -- and continue progress on traditional needs
New power system needs:
Transmission and supply/demand resources to meet economic and environmental goals
Renewable Portfolio Standards
Regional Greenhouse Gas Initiative (RGGI)
Traditional power system needs:
Transmission and supply resources for reliability
Growth in peak and overall energy use
Reliance on natural gas generation/need for dual-fuel

7. Resources in the North
Majority of renewable resource potential exists in:
Northern Maine
Northern New Hampshire
Quebec
New Brunswick
Newfoundland and Labrador
Northeast International Committee on Energy (NICE)
ISO-NE and New Brunswick System Operator (NBSO) developing inventory of renewable potential in New England and Eastern Canada

8. Improved Planning Process to Help Achieve these Goals
FERC Order 890 requires improvements to regional system planning (RSP) process
Identification of economic needs
Requirement for economic studies (3 per year)
Process for prioritizing economic studies
Stakeholder working group to implement these improvements
Define the scope of economic studies
Develop criteria for prioritization
Consider factors for determining market efficiency upgrades
ISO/NECPUC/NEPOOL Steering Committee to guide working group

9. Improved Transmission Planning Process, Next Steps
Working group to convene first meeting in March
NECPUC considering cases for economic study within the region
NICE Committee considering options for increased imports from Canada
Goal is to create evaluation framework that can select the best transmission solutions for the region
