The United States has its first large offshore wind farm, with more to come

America's first commercial-scale offshore wind farm is officially open, a long-awaited moment that helps pave the way for a succession of large wind farms.

Danish wind energy developer Ørsted and the utility Eversource built a 12-turbine wind farm called South Fork Wind 35 miles (56 kilometers) east of Montauk Point, New York. New York Gov. Kathy Hochul will be on Long Island Thursday to announce that the turbines are delivering clean power to the local electric grid. Interior Secretary Deb Haaland is expected to attend.

Achieving commercial scale is a turning point for the industry, but what's next? Experts say the nation needs a major buildout of this type of clean electricity to address climate change.

Offshore wind is central to both national and state plans to transition to a carbon-free electricity system. The Biden administration has approved six commercial-scale offshore wind energy projects, and auctioned lease areas for offshore wind for the first time off the Pacific and Gulf of Mexico coasts. New York picked two more projects last month to power more than 1 million homes.
