Incremental renewable capacity continues to provide significant and quantifiable benefits to the New England grid and its customers. In this report, Daymark Energy Advisors (Daymark) analyzed the market and environmental benefits of 1,200 megawatts (MW) of incremental land-based renewable capacity for the New England region. The results demonstrate that the benefits of renewables accrue broadly throughout the region through the reduction in energy prices and reduced greenhouse gas emissions, and that all states yield benefits regardless of the specific contracting circumstances for the output of the resources.
In this report, Daymark evaluated two portfolios of incremental renewable resources: 1,200 MW of land-based wind (the “Wind Only” case), and a portfolio of 900 MW of land-based wind and 300 MW of solar (the “Wind+Solar” case). Daymark modeled these resources using our New England production cost model built on the PLEXOS modeling platform over a 20-year study period. For modeling purposes, the resources were sited in Maine, where most planned large-scale renewable projects are located.
