Companies bet big that offshore wind farms in America will at last start turning

能源公司們押寶美國海上風(fēng)力發(fā)電場終迎新機

The future of clean energy depends on meetings like the one held at a small hotel in a small city in Massachusetts last month. Residents of New Bedford came together to voice their opinions about an offshore wind proposal from a company called Vineyard Wind. To date, such projects have not fared well in America; opponents have blocked big offshore wind farms. But opposition has dwindled. Though lobstermen fretted about local crustacea, supporters of the project in New Bedford touted the new jobs that would be on offer. Bureaucrats overseeing the plan offered heart-shaped chocolates at the sign-in table. If Vineyard Wind secures the necessary approvals, the project would be, astonishingly, America’s first large offshore wind farm. Construction could begin by the end of the year.

After nearly two decades of fighting, the wind industry is poised to sweep into American waters. In February a number of European energy giants, including Royal Dutch Shell, EDF, Equinor and Orsted, bid to build New York’s first offshore wind project, with a decision due this spring. Other plans are moving forward, from Virginia to New Hampshire. In total, states have sanctioned nearly 17,000 megawatts of offshore wind power. This increase is almost as large as Europe’s entire offshore wind market. Yet America remains perilous for wind developers, not just because of lingering opposition, but owing to a lack of a local supply chain to help with turbine construction. Ports seem inadequate to handle all the work. For global energy firms these are big risks, but they could be more than offset by the potential rewards.

More than 4,000 wind turbines already twirl off the coasts of Europe. In America, just five short turbines poke out of the waves near Rhode Island, despite the north-east’s shallow waters, high wind speeds and millions of energy-hungry consumers. America’s most famous offshore wind project remains one never built. Cape Wind, proposed in 2001, spent 16 years battling fishermen and rich landowners, including the Kennedy family, whose concern over climate change did not dull their desire for an unspoilt view. Faced with such headaches, wind developers invested in Europe or sought firm ground in America’s Midwest, home to big gusts and residents accustomed to using land for both pleasure and purpose.

On firm ground

腳踏實地

Among the things that have changed is technology. Operators are now able to build bigger turbines that can be sited farther from shore. And because turbines have become so large and powerful, firms need to install fewer of them to generate the same amount of electricity, which lowers development costs. Vineyard Wind plans to supply electricity to Massachusetts at 6.5 cents per kilowatt hour, which—though helped by a generous federal tax credit—is about the same price as electricity from German offshore wind farms.

State policies are boosting the industry, too. North-eastern governors are keen to burnish their green credentials to voters concerned about climate change, but the region has little room for big solar or wind farms on land. Massachusetts passed a law in 2016 requiring state utilities to procure about 1,600 megawatts in offshore wind power over the next decade, provided they receive reasonable bids. Other governors in the north-east have followed suit, becoming more bullish after Vineyard Wind’s announcement of low electricity prices. So far, President Donald Trump’s administration has been supportive.

The result is a frenzy. When, in 2015, the government auctioned a site off the Massachusetts coast, the winning bid was $281,285—“a very clear indicator of a market that was basically dead”, says Thomas Brostrom, who leads the North American business for Orsted, a Danish energy firm. In the latest auction in Massachusetts, in December, each lease sold for over 400 times that sum. European developers are battling it out, some adopting all-American names. In Massachusetts, for instance, Orsted’s subsidiary is Bay State Wind; Vineyard Wind is a partnership of Copenhagen Infrastructure Partners and a subsidiary of Spain’s Iberdrola, and Mayflower Wind is a joint venture between Shell and EDP Renewables, whose headquarters are in Madrid. Enbw, a German utility, is bidding along the east coast but is also eyeing waters off California (where the steep continental shelf will need floating turbines that have yet to be deployed at scale).

Despite enthusiastic governors, companies must still secure leases and contracts to sell electricity to utilities. Orsted, for one project, anticipates needing more than 20 permits and approvals from federal, state and local agencies. It has spent $510m to acquire Deep water Wind, one of the few American offshore developers, in part to help it deal with complex regulations.

Even if firms manage all that, other factors threaten to push up costs. The region has no big turbine manufacturers, so firms must pay to transport parts from Europe. A 99-year-old law means that they cannot use European ships that are specially designed to install turbines. No such American ship yet exists. There are insufficient ports to handle the heavy components needed for turbines. And an investment tax credit for wind is due to expire in 2020. States are rushing to hold auctions this year, but inevitably many projects will come too late to use the credit. That may lift the price of electricity from wind projects.

Wood Mackenzie, a consultancy, expects growth in offshore wind to subside after the tax credit expires, then pick up again in the mid-2020s as technology advances and factories open in America. States are vying to support the industry’s future growth. “My goal is to make Massachusetts the Denmark of North American wind,” says Stephen Pike, who leads the state’s efforts to promote a green economy.

In the meantime, Vineyard Wind is advancing its project, step by step. In January the company signed an agreement with the Natural Resources Defense Council, promising, among other things, to time construction to avoid disturbing the endangered North Atlantic right whale. It recently hammered out a deal with fishermen in Rhode Island, who remain concerned about the turbines’ effect. Lars Pedersen, chief executive of Vineyard Wind,remains optimistic. “It’s a challenging regulatory system, it’s litigious and so on, but if you can deliver jobs and clean energy at an affordable price,” he says, “I believe this is a huge opportunity.”
