The Bill for Offshore Wind Power Is Rising

With offshore wind projects bleeding cash, governments will have to pay more to hit their clean-energy targets. Recent auctions show just how much more.

Higher prices for steel, labor and debt financing have raised the cost of developing a wind farm by almost 40% since 2019. It is a big problem for developers like Danish energy company Ørsted, which signed power supply agreements a few years ago at prices that no longer cover today’s costs.

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, equivalent to $4.7 billion at current exchange rates—although its issues are mainly with faulty onshore turbines rather than offshore ones.

Germany last week stepped in with a multi-billion-euro state-backed guarantee for 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.

The industry’s deepest challenges are in the U.S., a market that was meant to be the next growth frontier following the Biden administration’s pledge to install 30 gigawatts of offshore capacity by 2030. Instead, 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, according to BloombergNEF, and the bill could rise further as new contracts include inflation protection that will shield developers from future cost pressures.

Paying higher, more flexible prices for fresh contracts might still end up being a cheaper solution for New York than renegotiating old ones. Developers including BP and Equinor asked for increases of 49% on average over what was agreed in their original power supply contracts. They may pull out after getting a no from the state.

Governments and companies had become used to the cost of renewable energy heading only one way. The global average levelized cost of electricity generated by offshore wind—a measure of the minimum price necessary to cover the lifetime costs of a project—has plunged by 66% since 2009, according to BloombergNEF data.

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.

The new reality makes it harder for governments to meet their net-zero targets while also keeping power costs low for the public. But densely populated areas like New York may not have much choice but to exploit offshore wind. Clean alternatives such as land-based wind and solar farms are tough to roll out where space is at a premium.

The European Union is also aware that if governments don’t do more to support local companies like Siemens Energy, Chinese turbine manufacturers that enjoy generous subsidies from Beijing will be only too happy to step in. This would help the EU stay on track with an ambitious plan to increase its offshore wind capacity sevenfold by 2030, but at the expense of the bloc’s energy independence.

Harnessing the winds out at sea is still a key part of countries’ plans to cut their carbon emissions and boost energy security. But governments can no longer pretend that these political objectives can come cheap.

The stock market had a decent summer. Investors are bracing for a bumpier fall.

In the past couple of months, equity investors cheered soaring profits at big companies, shrugged off jitters in the bond market and nudged megacap tech shares back near records.

Now, as the post-Labor Day stretch begins, a number of new challenges lie ahead: ever-shifting odds of an interest-rate increase from the Federal Reserve. Sky-high expectations after a stunning earnings season. The persistent threat of higher consumer prices as fighting in the Middle East drags on.

“You’re moving from this earnings-driven market to this macro-driven market with the Fed, inflation and interest rates in focus,” said Keith Lerner, chief investment adviser for Truist Advisory Services. “It tends to be a choppier period.”

Historically, every major U.S. stock index experiences its worst average return in September. The Dow Jones Industrial Average has slid an average 1.1% in the ninth month of the year, in data that dates back to the 19th century. The S&P 500 has seen the same average decline—and for every September dating back to 1928, the benchmark ends the month lower more than half of the time.

Analysts caution against reading too much into those seasonal patterns. But in recent weeks, new reasons for investor caution have emerged. One of the largest: the looming threat of an interest-rate increase from the Fed, which announces its next policy decision on Sept. 16.

Chairman Kevin Warsh’s decision to ditch forward guidance and take more of his cues from markets has muddied the waters for investors when it comes to monetary policy. That has left traders scouring Fed governor speeches and economic-data reports for clues on the central bank’s next move.

“There’s going to be a lot of eyes on those numbers,” said John Luke Tyner, head of fixed income and portfolio manager at Aptus Capital Advisors.

The past couple of weeks offered just one example of how frequently those expectations can change. After Warsh struck a hawkish tone during remarks on Aug. 28, the odds of a hike at the Fed’s next meeting jumped from 35% before the speech to 58%, according to CME FedWatch data.

On Thursday, Fed governor Christopher Waller made a case for leaving rates where they are. Interest-rate futures showed coin-flip odds between a hike and a hold. Then Friday’s robust jobs report amped up rate-hike bets once more, back to a roughly 60% chance of higher rates after the meeting.

“Rates have really been driving the car for equities the last few weeks,” said Ross Mayfield, an investment strategist at Baird.

That uncertainty comes as an unruly bond market could put pressure on stocks. Treasury yields have marched higher for much of the summer, driven by concerns about rising oil prices, growing U.S. budget deficits and a deluge of tech-company bonds now competing for investors’ cash. Last week, the rout went global, pushing yields to multiyear highs in Japan, Germany and the U.K.

Higher bond yields can drag on stock prices and lift borrowing costs for companies and consumers across the economy.

Rising prices remain the top concern for bond traders, and continued fighting between the U.S. and Iran has done little to ease those worries. The national average price of diesel climbed to a record of $5.850 on Friday, according to AAA. That is up from $3.712 a year ago.

Investors will get more insight on the path of prices this week, with the much-awaited consumer-price index report due Friday and a reading on producer prices Thursday.

With another blockbuster earnings season in the books, some analysts have also warned that any boost from the third-quarter reports due in the coming months could be minimal. Back-to-back quarters of standout profits have raised expectations and made it especially difficult to impress traders. Custom-chip company Broadcom, for example, said Wednesday that it more than tripled its earnings and nearly doubled its revenue. Shares slipped 2.7% the next session.

Many analysts note there are plenty of reasons not to panic. The economy is in impressive shape, thanks to a healthy labor market and the rippling effects of the artificial-intelligence investment boom. Profits are booming at America’s biggest companies. The Cboe Volatility Index has dropped to its lowest levels of 2026. Credit spreads are tight, a sign bond investors aren’t concerned about economic conditions that could hurt companies.

But the mood has shifted from the euphoria that felt tangible when the Nasdaq was notching back-to-back records early this summer. The question, Mayfield said, is whether the fundamentals that have bolstered the bull market so far can stretch the rally into 2027.

“There are more anxieties or uncertainties about the backdrop,” he said. “It does feel like a transitional moment.”
