Offshore Wind Saves New England Households $60 a Year, In 2050

A new study commissioned by The Nature Conservancy explores the potential of offshore wind in New England's energy mix. The report, conducted by Dunsky Energy + Climate Advisors, models three scenarios for the region's power generation from 2035 to 2050. One key finding is that a power mix including offshore wind could save households $60 a year by 2050, compared to a fossil and nuclear-heavy alternative. However, this savings figure comes with significant caveats.

The $60 annual savings is not a reduction in current electric bills but a difference between two costly futures. By 2050, the least-cost mix (including offshore wind) would add about $310 to annual household generation costs, while the fossil and nuclear option would add $370. The savings materialize only under specific conditions, particularly when natural gas prices reach $6 per million British thermal units, roughly Connecticut's average over the past five years.

The study's findings depend heavily on assumptions about fuel prices and technology costs. Offshore wind becomes competitive only when gas prices rise, and even then, the least-cost mix still includes significant gas-fired capacity. The report also excludes key costs like transmission expenses, labor, and carbon emissions, leaving some uncertainty about the true financial impact on ratepayers.

Connecticut has already invested heavily in offshore wind, including $211 million to redevelop State Pier in New London and a ratepayer-backed contract for 304 megawatts from Revolution Wind. While offshore wind could reduce exposure to volatile gas prices, the study does not prove it will lower electric bills. The report emphasizes that all energy sources should compete on reliability and full cost to ratepayers before long-term contracts are approved.
