Hornsea One to Start Generating Power

Hornsea Project One, slated to be one of the largest wind farms in the world upon completion, began supplying energy to the U.K. electricity grid this week, according to reports. The project, 74 miles off the coast of Yorkshire, England, is the first of four planned for the area.

According to The Guardian, Danish developer Ørsted is ready to step in to help fill the energy demands left by failed plans for nuclear power options.

Hornsea Project History

According to Ørsted, the wind farm will have 174 monopiles total. In February of last year, installation was reportedly being carried out by GeoSea’s installation vessel, Innovation, which is equipped to carry four monopiles at a time. Each one is 213 feet long, weighs around 800 tons and is 26 feet in diameter.

Innovation will also be used to install some of the project’s transition pieces. The vessel can carry 31,400 tons and 100 people onboard, and is also a self-elevating ship that can extend four legs down to the ocean floor, noted CleanTechnica. Innovation can then become an offshore installation platform.

Ørsted announced in 2017 that Wilton Engineering Services Ltd. would be responsible for portions of the construction of the structures, including coating.

In late February 2018, the developer announced the selection of Siemens Gamesa Renewable Energy as the exclusive wind turbine supplier for Hornsea Project Two, a successor to Hornsea Project One slated to be operational by 2022.

Generating Power

Hornsea One is to cover 407 square kilometers, with a 1.2 GW capacity to power 1 million homes. The first two phases of the project will use 7-MW turbines, though later portions of the Hornsea development may use 10-MW-plus turbines. Subsidies have already been awarded to a second stage that is slated for completion in 2020.

“The ability to generate clean electricity offshore at this scale is a globally significant milestone at a time when urgent action needs to be taken to tackle climate change,” said Matthew Wright, UK managing director of Ørsted.

The first Siemens Gamesa SWT-7.0-154 turbine at Hornsea One started spinning earlier this week. Roughly half the components for the project are being produced in the U.K. Henrik Poulsen, Ørsted’s chief executive, has also noted that he is in talks with major manufacturers about use of the next generation of turbines.
