Offshore wind is being sold as 840 offshore wind turbines rated at 10 megwatts each will be enough to power 400,000 homes and businesses 24/7. The total number of megawatts of the project is 840 megawatts.
All turbines suffer parasitic electric losses. A turbine can use up to 10 percent of its own power to charge its batteries, run lights, heat, AC, computer, alarms, brakes, and anything any power plant needs.
The AC or DC power sent from the ocean turbines to onshore depending on the length of the cable suffers electric line loss.
Offshore wind turbines suffer high maintenance losses, submarine cable outages, and lightning can cause long-term blade outages. The 2016 Block Island, Rhode Island wind farm was shut down for routine maintenance during the summer of 2021. In 2019 the submarine cable linking the wind farm to the mainland became exposed which caused electric ratepayers to pay 30 million for repairs.
A wind turbine only generates power between 6 miles per hour and 45 miles per hour. At 6 miles per hour, the turbine is barely producing power. As the wind speed picks picks up the number of megawatts being produced increases proportionally to ten megawatts when the wind speed reaches 45 miles per hour. At 46 miles per hour or any sudden shifts of wind, the brakes come on and no power is produced as it shuts down.
Knowing these facts how is it possible for 84 offshore wind turbines rated at 10 megwatts each to be enough to power 400,000 homes 24 hours a day 7 days a week? It's fake news.
Last, No one knows the outcome of new 10-megawatt ocean wind turbines off the coast of Massachusetts in a historic storm.
