The Bill for Offshore Wind Power Is Rising

Prices in recent offshore auctions have increased by anywhere from 20% to 70%

By Carol Ryan of The WSJ. Excerpts:

"Higher prices for steel, labor and debt financing have raised the cost of developing a wind farm by almost 40% since 2019."

Developers’ struggles are having a knock-on effect on the turbine makers that supply them, including Vestas, GE and Siemens Energy. The latter’s wind unit, Siemens Gamesa, lost €4.3 billion in the company’s latest fiscal year"

"Siemens Energy, which told investors at a capital markets day on Tuesday that its wind division won’t make a profit until after 2026. GE says its offshore wind business will lose $1 billion this year, and the same again in 2024."

"developers are taking multibillion-dollar impairments on U.S. projects, or backing out entirely. According to BloombergNEF, of the 21.6 gigawatts of offshore wind power awarded or signed so far in the U.S., a quarter has been canceled and almost another third is at risk."

"Governments are now responding by topping up the prices at which they auction off licenses. Britain was forced to raise its guaranteed price for offshore wind power by 66% after a September auction didn’t attract a single bid. The average price in New York’s latest offshore wind auction in October was a fifth higher than previous rounds"

"After years of becoming more competitive as a source of power, offshore wind is beginning to look expensive in some markets compared with fossil-fuel alternatives. Globally, new offshore wind projects still work out cheaper than natural gas ones and are level with coal. But offshore wind looks costly in the U.S., partly because the supply chain is so immature and will need heavy investment for several years."
