US Offshore Wind: What went wrong?

U.S. offshore wind has long been seen as a game-changer in the renewable energy world. With plans to install 30 GW of offshore wind power by 2030, it seemed the stars were aligned for this industry. There’s strong government backing, billions of dollars in private investments, and an endless coastline with favorable conditions. Yet, despite all this, things are far from smooth sailing. Supply chain issues, rising costs, and geopolitical tensions have become serious roadblocks, leaving many wondering: What went wrong?

1. Why Offshore Wind Looked Like a Winner

A. Government Support Federal and state governments have been huge fans of offshore wind. The Biden administration’s 30 GW target by 2030—enough to power roughly 10 million homes—sounded like a clean energy dream come true. States like New York and Massachusetts eagerly jumped on board, signing PPAs for big projects like New York’s 2.4 GW Empire Wind. With billions unlocked by the IRA, the industry seemed set to sail smoothly. Tax credits from the IRA have also unlocked $369 billion in climate and energy investments, making it clear that the government is betting big on offshore wind.

B. Big Investments The private sector jumped in with both feet. Ørsted, Equinor, and Dominion Energy made some pretty bold moves—like Ørsted’s Vineyard Wind 1 project, which alone will power over 400,000 homes. Dominion even built a $500 million vessel just to install these mega-turbines. That’s commitment. With over 20 GW of projects in the pipeline, it felt like offshore wind was about to revolutionize the U.S. energy landscape.

But as it turns out, Mother Nature wasn’t the only force they needed to reckon with.

2. What Went Wrong?

A. Supply Chain Chaos

Turbine Delays: Here’s where things started to wobble. Turns out, getting enough turbines—each with blades longer than a football field—isn’t as easy as just putting in an order and waiting for delivery. Turbine suppliers like Siemens Gamesa are facing major bottlenecks, with some deliveries delayed by a year or more.

Foundations and Subsea Cables: And it’s not just the turbines. Foundations and subsea cables, the unsung heroes of any wind farm, are facing delays too. Global demand has outpaced supply, pushing up prices by 30%. The result? Higher costs, longer waits, and plenty of developers learning that patience isn’t just a virtue—it’s a requirement in today’s wind industry.

Vessel Shortages: Oh, and let’s not forget about the vessel shortage. Offshore wind farms need specialized ships to install those towering turbines, and there just aren’t enough of them floating around. The U.S. fleet is, shall we say, a little thin. Dominion’s shiny new $500 million installation vessel won’t be operational until 2025, leaving developers scrambling to find European vessels, which are already busy. Imagine having a billion-dollar wind farm ready to go, and then realizing you don’t have the right tools to put it together.

B. The Geopolitical Mess - U.S. vs. China and Europe’s Energy Crisis

Tension with China: Geopolitical tensions have also thrown a wrench in the works. China controls a large chunk of the rare earth elements (neodymium, dysprosium, and praseodymium) needed for turbine generators, and U.S.-China trade restrictions have made these materials more expensive—by about 35%, in fact While the U.S. plans to ramp up domestic production, that’s not going to happen overnight. In the meantime, developers are left picking up the tab—and it’s not cheap.

Europe’s Scramble for Energy: Meanwhile, over in Europe, the energy crisis fueled by Russia’s war in Ukraine has triggered a massive rush to build offshore wind farms. Europe installed 2.5 GW of offshore wind in 2023 alone, gobbling up the same turbines, cables, and foundations that U.S. projects need. It’s a classic case of “first come, first served,” and unfortunately, the U.S. is left at the back of the line.

C. Rising Costs and Project Cancellations

Costs Are Skyrocketing: Over the past three years, inflation has been relentless. Steel prices—essential for turbine towers and foundations—have shot up more than 50%, while copper for subsea cables is at record highs.

Cancellations and Bankruptcies: It’s not just about squeezing margins. Some projects are getting delayed or scrapped. The Mayflower Wind project in Massachusetts has been put on hold due to cost increases and material shortages. Smaller developers are feeling the financial strain, and even major suppliers like Siemens Gamesa have posted losses in their offshore divisions. The pressure is real, and the entire industry is feeling it.

D. Transmission Woes - Getting Power to the Grid

Even if developers can get past the supply chain mess, there’s another looming challenge: the U.S. grid isn’t ready for all this new power. A recent estimate suggests the U.S. will need to invest $100 billion just to upgrade the grid for offshore wind. And as we all know, when it comes to getting massive infrastructure projects moving, government efficiency isn’t exactly famous for its speed.

3. Offshore Wind vs. Nuclear: Is Wind Still the Future of Energy Transition?

Offshore wind was supposed to be the hero of the U.S. energy transition, but now some are asking: Is offshore wind still the future, or is nuclear energy making a quiet comeback?

Nuclear power, especially SMRs are gaining renewed attention. SMRs are cheaper to build, more flexible, and don’t depend on the weather. In 2024, the U.S. Department of Energy boosted funding for SMRs, with hopes of bringing them online by 2030. As costs rise and offshore wind timelines get pushed back, nuclear might start looking like the steady, dependable option for the future.

So, the question remains: Will offshore wind manage to push through these growing pains, or is nuclear energy about to steal the spotlight?

4. Windy Road Ahead

Despite all the turbulence, the potential for U.S. offshore wind remains massive. But with rising costs, supply chain bottlenecks, vessel shortages, and the urgent need for grid upgrades, this ride is anything but smooth. Offshore wind may still be the future, but it’s starting to feel more like a marathon than a sprint.

Meanwhile, nuclear energy is quietly waiting in the wings. Could it be the unexpected hero of the clean energy transition? Or will offshore wind weather the storm and come out on top?

One thing’s for sure: The race to a cleaner energy future is far from settled. What do you think? Will offshore wind overcome these hurdles, or is nuclear the dark horse of the clean energy transition? Share your thoughts in the comments!
