WIND FARM UPDATE: UK Leads in Offshore Wind Market

The offshore wind industry has seen significant growth worldwide, with 162 wind farms now generating electricity. Among these, the United Kingdom stands out as the largest offshore wind market, boasting a total capacity of 104 GW. Last year, the UK witnessed the commissioning of the Hornsea One wind farm, currently the world’s largest operational offshore wind farm, with a capacity of 12 GW.

Germany follows closely behind with a total operational capacity of 77 GW, while China has rapidly emerged as a major player with 71 GW. Notably, China alone added over 2 GW of new offshore wind capacity in 2020. In contrast, Germany only connected 219 MW to the grid last year, with no new projects currently in progress. As a result, China is poised to surpass Germany and claim the third spot in the global offshore wind market.

This update highlights the dynamic landscape of offshore wind energy, with the UK leading the way and China making significant strides. The growth in offshore wind capacity underscores the importance of renewable energy sources in meeting global electricity demands while reducing carbon emissions.

Why is offshore wind more expensive?

Offshore wind farms are more costly to construct due to the need for complex infrastructure. Additionally, the maintenance of these farms is more challenging due to higher wind speeds, strong seas, and accessibility issues. Unlike onshore wind turbines, offshore turbines require a significant investment and are typically owned by corporations. However, they do provide employment opportunities during the development and operation of the wind farm.

The Hornsea Phase 2 offshore wind farm, set to be operational in 2022, will be the largest in the world. With 165 8MW wind turbines, it will generate 13GW of green energy, enough to power 14 million homes.

How much offshore wind is there?

Companies are actively pursuing offshore wind projects, both existing and newly available ones. The Biden administration has opened up vast areas of federal waters for offshore wind development. In February, the Bureau of Ocean Energy Management (BOEM) sold leases for six offshore wind areas near New York and New Jersey, covering 488,000 acres. These areas are expected to support approximately 56 gigawatts of offshore wind development. Additionally, BOEM held the first-ever auction for the Pacific region in early December, awarding offshore wind rights for five lease areas near Northern and Central California. The winning bidders spent a total of $757 million to lease the tracts, which span 373,000 acres and could provide 45 gigawatts of renewable generation capacity. This capacity is crucial for California to achieve its goal of 100 percent zero-carbon electricity by 2045.

Unlike projects on the East Coast, which use fixed-bottom foundations, most projects on the West Coast will require floating turbines. This is due to the steep drop in the outer continental shelf along the Pacific seaboard, reaching depths of 3,280 feet or more. Developers will need to utilize floating platforms and other buoyant technologies to generate wind power in these deeper waters. The recent lease sale in California is evidence of the growing momentum in the industry, particularly for floating offshore wind development. Interior Secretary Deb Haaland stated that the Biden administration aims to deploy 15 gigawatts of floating offshore wind capacity by 2035, while California has set targets for building 25 gigawatts of floating wind projects by 2045.

Currently, there is limited offshore floating wind capacity globally, with only about 121 megawatts operating in 2021, mostly in Europe. Therefore, it is not surprising that major European developers dominated the California auction. Norwegian energy giant Equinor, one of the winning bidders, already has floating offshore wind projects in Scotland and Norway. However, efforts are being made in California to ensure that local communities are prepared to participate in the economic opportunities these projects will bring. Environmental groups are partnering with state policymakers, port operators, and labor union leaders to develop job training programs for the nation’s first floating offshore wind farms.

The complexity of these projects requires a high level of skill, according to Eddie Ahn, the executive director of Brightline Defense, a nonprofit organization based in San Francisco. Ahn emphasized the importance of equitable economic development as this technology is deployed. He mentioned ongoing discussions with state government agencies, local community groups, and the Port of Humboldt’s leaders to explore workforce opportunities in the area. California recently approved a $105 million grant to renovate the port, supporting offshore wind activities such as building and staging floating wind foundations and handling large cargo vessels. Ahn stressed the significance of ensuring that these job opportunities benefit local underemployed and unemployed communities.

Who owns the most wind farms?

During the early stages of the wind power industry, citizen investors in Denmark, the Netherlands, and Germany were the driving force behind project development. However, in recent years, the landscape has shifted, and now utilities, independent power producers (IPPs), and commercial and industrial enterprises are leading the way in wind farm development globally. This trend is evident in the top 15 wind farm owner-operators, who collectively hold over one-third of the total 650 GW of onshore and offshore assets worldwide.

China, being the largest wind market, has a significant presence in the top 15 ranking of wind asset owners. Chinese utilities dominate this ranking, with most of their assets located in the Asia Pacific region. These Chinese asset owners account for over 60% of total wind assets in China and more than 145 GW of capacity, which is over one-fifth of the global wind capacity. The remaining top asset owners are active globally, with six headquartered in Europe and two in the US.

A similar trend can be observed in the offshore sector, where the top 10 offshore asset owners hold over half of the global offshore wind capacity. Europe and China are the primary players in this market, with Orsted leading as the world’s number one offshore wind operator, owning 367 GW of offshore wind capacity across Europe, Asia Pacific, and North America.

The diversification of ownership and investors in wind assets is driven by common factors such as stable investment with predictable returns over a long period, typically twenty years or more, and a relatively low-risk profile. As the costs of wind power have significantly decreased in the past decade and technology innovation has opened up new opportunities, leading wind farm owner-operators have adapted their strategies to maximize revenue while minimizing risk.

In line with the consolidation trends seen in wind original equipment manufacturers (OEMs), asset owners have also engaged in mergers and acquisitions (M&A) activities to expand their wind power portfolios and capabilities. In the offshore sector, there is a trend of utilities joining forces to build and operate offshore projects, managing the increasing size and complexity of such projects and reducing risk.

Wind power owner-operators are also exploring various strategies to generate more capital from their assets and portfolios. These strategies include offering corporate power purchase agreements (PPAs), seeking opportunities with hybrid or colocated projects, providing additional services like asset management and optimization, and diversifying their technology offerings.

Utilities and asset owners view wind power as a promising and stable long-term investment, leading traditional energy companies to spin off renewables businesses and focus on these assets. European utilities, in particular, are actively seeking new opportunities to build their portfolios in emerging markets.

As the energy transition progresses, new solutions and opportunities in the wind power sector continue to evolve, providing asset owners and investors with diverse avenues to generate revenue and manage risks in their portfolios.
