Wind energy off the New England coast can powerfully reinforce the reliability of the region's electric grid, particularly during winter when the system is most vulnerable to energy shortages. Combined with the energy available from onshore wind and solar resources, an offshore wind fleet can support a shift toward local solutions for winter reliability in New England, bringing consumers much-needed relief from high seasonal electricity bills.
A Union of Concerned Scientists analysis of winter 2024–2025 wind speed data shows that the energy delivered by just two offshore wind projects, totaling 1,500 megawatts (MW) of capacity, would have lowered the risk of power outages, based on a key reliability metric, by 55 percent over the course of the season. A larger fleet of 3,500 MW would have reduced the risk of outages by 75 percent. In either case, the scale of energy delivered by an offshore wind fleet would have increased the total winter energy supply from local renewable resources above the energy supply from imported liquified natural gas.
