Outline
OUTLINE

  • METHODOLOGICAL CONCERNS

  • METHODOLOGICAL FIXES

  • RESULTS


I methodological concerns
I. METHODOLOGICAL CONCERNS

  • With benefits that are here:

    • Jobs benefits from wind

    • Natural gas price decreases

    • With benefits that are not here:

      • Consumer protection against natural gas price increases

      • Consumer protection against high carbon prices


I. METHODOLOGICAL CONCERNS (continued)

  • Isolating transmission benefits from generation

    • Consequence is that it pushes the Board to consider non-traditional benefits


Ii methodological fixes
II. METHODOLOGICAL FIXES

  • Intended consequence is to allow greater reliance on traditional benefits

    • Base Case uses current wind capacity (3.7 GW), Change Case 6.9 GW

    • Three alternative natural gas price forecasts

    • Three alternative CO2 prices/taxes


Iii results
III. RESULTS

  • SPP modeled 6 scenarios for Boston Pacific


Iii results continued
III. RESULTS (continued)

  • Two analytical points

    • Higher natural gas prices increase production cost savings


Iii results continued1
III. RESULTS (continued)

  • CO2 prices decrease production cost savings


Iii results continued2
III. RESULTS (continued)

  • Additional benefits categories to consider first

    • Reliability

    • Seams

    • Explicit modeling of later years
