What Ørsted Hornsea offshore wind farms are and how they work

Ørsted Hornsea offshore wind farms are large-scale wind power projects located in the North Sea that use offshore wind turbines to generate electricity and transmit it to onshore grids through subsea cables Ørsted, 11/2023.

Each Hornsea project consists of many individual turbines, offshore substations, and export cables that bundle power and deliver it to a connection point on land where the electricity is integrated into the national transmission system Ørsted, 10/2023.

The wind farms operate by converting kinetic energy from sea winds into mechanical rotation and then into electrical energy through generators in the nacelles mounted on the turbine towers U.S. EIA, 01/2024.

Why Ørsted Hornsea offshore wind farms matter for US consumers and industry

For US readers, Ørsted Hornsea offshore wind farms provide a reference point for how offshore wind can contribute to decarbonizing power systems, a key policy priority in the United States as federal agencies support more offshore wind leasing and permitting U.S. DOE, 02/2024.

Hornsea projects demonstrate technical concepts such as siting turbines far from shore, managing large wind farms, and integrating variable renewable power into grids, themes that are relevant to US East Coast and West Coast energy planners BOEM, 01/2024.

US consumers can draw lessons from European offshore wind about how utility-scale wind power might diversify energy supply alongside solar, onshore wind, and other resources, potentially supporting cleaner electricity portfolios over time U.S. EIA, 03/2024.

Ørsted Hornsea offshore wind farms in the US and global market

Globally, offshore wind development in regions like the North Sea illustrates how countries have expanded renewable capacity in parallel with policy support, and US policymakers reference these experiences when developing their own offshore wind strategies IEA, 09/2023.

In the United States, federal and state authorities have identified offshore wind as a potential contributor to long-term clean energy objectives on the Atlantic coast, Gulf of Mexico, and Pacific coast, using international project data as one input for planning White House, 10/2023.

Hornsea-style large offshore wind farms illustrate considerations such as grid connection design, environmental assessment, and collaboration with fisheries, which are also captured in US environmental review processes related to offshore wind development NOAA, 08/2023.

• Offshore location in the North Sea, far from shorelines
• Arrays of wind turbines connected to offshore substations
• Subsea export cables delivering power to onshore grids
• Use of high-voltage equipment to manage power transmission
• Relevance as a reference model for emerging US offshore wind regions

Ørsted, the company behind Hornsea offshore wind farms, develops and operates renewable energy projects in several regions with a focus on offshore wind and other clean energy technologies.
