Wind turbine market share in the UK

Shares are of operational capacity and turbines at wind farms where the turbine make is known. Sites using more than one manufacturer are split by turbine count.

Offshore wind turbine manufacturers

Turbine-level data covers 100% of operational offshore capacity, so these offshore shares are close to complete. See every site on the UK offshore wind farms guide.

Onshore wind turbine manufacturers

Onshore turbine makes are known for 237 of 785 operational onshore projects (32% of onshore capacity), mostly larger and older sites, so treat these shares as indicative.

Most common wind turbine models in the UK

Model names are given as recorded by each source, so the same turbine can appear under slightly different names.

Wind turbine brands and mergers

Many older UK wind farms use brands that no longer exist. Bonus was bought by Siemens in 2004, and Siemens' wind business merged with Gamesa in 2017 to form Siemens Gamesa. NEG Micon merged into Vestas in 2004, and MHI Vestas was the Mitsubishi and Vestas offshore joint venture until Vestas took full ownership. REpower was renamed Senvion in 2014, Acciona Windpower merged into Nordex in 2016, and GE acquired Alstom's wind business in 2015. Market share above counts each turbine under its current manufacturer group, while individual wind farm pages show the brand as recorded.

Turbine data and coverage

The REPD does not record turbine makes or models, so this guide combines three open sources, matched to REPD records: Open European Offshore Wind Turbine Database (EuroWindWakes) (Fischereit, Vollmer and Hansen, EuroWindWakes; includes data © OpenStreetMap contributors, ODbL 1.0); Wikipedia lists of onshore wind farms in the UK (Wikipedia contributors, CC BY-SA 4.0); OpenStreetMap turbine tags (© OpenStreetMap contributors, ODbL 1.0). Offshore data is turbine-level and near-complete; onshore data is matched by name and location and covers 32% of onshore capacity. Where sources disagreed or a match was uncertain, the wind farm was left unmatched rather than guessed.

Frequently asked questions

Sources and method

Figures come from the July 2026 extract of the Department for Energy Security and Net Zero's Renewable Energy Planning Database (REPD), which tracks UK renewable projects through planning, construction and operation. Each figure is calculated directly from the source records and refreshes when a new snapshot is imported.

The REPD counts project records, not physical sites. Extensions, repowering schemes and later phases can appear as separate records, and very small turbines below the database threshold are not included. Status reflects the snapshot date; developers' later announcements can differ. Read the full methodology and limitations.
