Earlier authorities experiences, together with one 2024 report from the Division of Vitality and a 2025 report from the Authorities Accountability Workplace (an unbiased authorities watchdog), have identified this problem prior to now.
“So far, no mitigation know-how has been capable of absolutely restore the technical efficiency of impacted radars,” because the DOE report places it. Nevertheless, there are strategies that may assist, together with software program that acts to take away the signatures of wind generators. (Consider this as just like how noise-canceling headphones work, however extra sophisticated, as one knowledgeable informed TechCrunch.)
However probably the most widespread and useful tactic, in response to the DOE report, is collaboration between builders and the federal government. By working collectively to web site and design wind farms strategically, the teams can be certain that the initiatives don’t intrude with authorities or army operations. The 2025 GAO report discovered that authorities officers, researchers, and offshore wind firms have been collaborating successfully, and any considerations might be raised and addressed within the allowing course of.
This and different challenges threaten an business that might be a significant boon for the grid. On the East Coast the place these initiatives are positioned, and in New England particularly, winter can convey tight provides of fossil fuels and spiking costs due to excessive demand. It simply so occurs that offshore winds blow strongest within the winter, so new initiatives, together with the 5 wrapped up on this struggle, might be a significant assist throughout the grid’s biggest time of want.
One 2025 examine discovered that if 3.5 gigawatts’ price of offshore wind had been operational throughout the 2024-2025 winter, it could have lowered vitality costs by 11%. (That’s the mixed capability of Revolution Wind and Winery Wind, two of the paused initiatives, plus two future initiatives within the pipeline.) Ratepayers would have saved $400 million.
Earlier than Donald Trump was elected, the vitality consultancy BloombergNEF projected that the US would construct 39 gigawatts of offshore wind by 2035. At the moment, that expectation has dropped to simply 6 gigawatts. These authorized battles may push it decrease nonetheless.
What’s hardest to wrap my head round is that a number of the initiatives being challenged are almost completed. The builders of Revolution Wind have put in all of the foundations and 58 of 65 generators, and so they say the venture is over 87% full. Empire Wind is over 60% carried out and is slated to ship electrical energy to the grid subsequent yr.
To hit the pause button so near the end line is chilling, not only for present initiatives however for future offshore wind efforts within the US. Even when these authorized battles clear up and extra builders can technically enter the queue, why would they need to? Billions of {dollars} are at stake, and if there’s one phrase to explain the present state of the offshore wind business within the US, it’s “unpredictable.”
