Request for Information Regarding Maine Offshore Wind Renewable Energy and Economic Development Program

The Union of Concerned Scientists (UCS) recommends that Maine's offshore wind procurement process prioritize larger nameplate capacities to maximize grid reliability. Based on an analysis of winter seasons from 2000 to 2022, UCS found that offshore wind fleets of 1500 MW, 4000 MW, and 8000 MW could substantially reduce the number of days the New England grid faces elevated energy shortfall risk. The document argues that offshore wind is an ideal solution for winter reliability because its output typically increases during cold snaps, unlike fossil fuel supplies which are subject to global market volatility and import constraints.

• Analysis of 22 past winter seasons (2000-2022) shows that offshore wind fleets can drastically reduce the average number of days with elevated energy shortfall risk (demand above 350,000 MWh) from 60 days per season to 35 days with 1500 MW, 11 days with 4000 MW, and just two days with 8000 MW.
• Offshore wind is characterized as an effective mitigation tool for winter energy shortfalls because its energy supply increases during winter and typically operates at above-average output during extreme cold, providing a stably priced, locally controlled resource.
• Current mechanisms to ensure winter fuel security in New England, such as the Mystic Cost of Service Agreement and the Inventoried Energy Program, are expensive for ratepayers and vulnerable to global disruptions, having cost approximately $830 million over three winter seasons (2022-2025).
• The deployment of offshore wind could eliminate the need for expensive and polluting oil-fired plants, specifically citing the 822 MW Wyman Station in Yarmouth, Maine, which is the state's largest power plant.
• UCS recommends that the Maine Governor’s Energy Office (GEO) and the Public Utilities Commission (PUC) include reliability benefits and the avoided costs of alternative cold-weather energy supplies in their cost-benefit evaluations of offshore wind bids.
• The risk of winter energy shortfalls is expected to increase in the coming decades due to the electrification of heating and transportation, which will drive higher overall power demand during winter.
