Oil dealers say it would kill their industry and cost thousands of jobs. They and other critics also say the electricity from offshore wind would be very expensive, and note that customers would have to pay higher electricity bills to make it possible. ...the cost of offshore wind power and how to pay for it got a bit more real when Chuck Digate stepped up to testify. Digate is managing general partner of Neptune Wind LLC, a Massachusetts company that is interested in developing an ocean wind farm in Maine. It will cost an estimated $1.5 billion to build a 250-megawatt ocean wind project, he said. Its power would cost 22 cents a kilowatt hour, and with no state support to help financing debt, he said, it would add $8 a month to the average household's electricity bill.
