A big day for green energy in America happened on the East End.

Gov. Kathy Hochul was at Stony Brook University's Southampton campus to announce the completion of South Fork Wind.

South Fork Wind is the first utility-scale offshore wind farm in federal waters, projected to generate power for 70,000 Long Island homes.

The off-shore wind farm is 35 miles off the coast of Montauk and is equipped with 12 turbines.

According to the South Fork Wind website, the project has resulted in 1,000 short and long-term jobs across five states.

South Fork Wind will generate power to 70,000 Long Island homes and avoid 6 million tons of carbon dioxide over 25 years.

The $2.01 billion clean energy project has not been without controversy. News 12 has reported Long Island 's Commercial Fishing Association had concerns about dangers that cables from the site could have on boats. Some fishermen have also argued that they should be compensated for lost fishing ground.

The farm has already been hard at work, delivering clean energy to the Long Island grid in December.

LIPA says Long Islanders are paying for the project with an estimated $1.27 increase to their energy bills, an increase that began in January.
