LONG BEACH TOWNSHIP, N.J. (AP) — New Jersey is seeking a new round of proposals to build wind energy farms off its coastline, forging ahead with its clean energy goals even as local opposition and challenging economics create blowback to the effort.

The state Board of Public Utilities on Tuesday opened a fourth round of solicitations for offshore wind farms, giving interested companies until July 10 to submit proposals.

“Advancing this solicitation really demonstrates that we are committed to seeing the economic development that offshore wind is bringing to New Jersey and will continue to bring, as well as the clean energy that is so important for the residents of the state,” said the board’s president, Christine Guhl-Sadovy.

There are currently three preliminarily approved offshore wind projects in New Jersey.

One from Chicago-based Invenergy and New York-based energyRE. Called Leading Light Wind, would be built 40 miles (64 kilometers) off Long Beach Island and would consist of up to 100 turbines, enough to power 1 million homes.
