How big is Seagreen?

Seagreen has a recorded installed capacity of 1.07 GW. That figure is the capacity registered in REPD, which is the scheme as consented — the metered output of a site can differ.

Who operates Seagreen?

REPD records the operator as SSE / Seagreen Wind Energy Ltd. Ownership of built renewable assets changes hands regularly and REPD is published quarterly, so treat this as the operator of record rather than confirmation of who owns it today.

When was Seagreen approved and built?

The application was submitted on 23 October 2012. Permission was granted on 16 May 2017, 55 months later. The site became operational on 16 October 2023, 77 months after consent.

Source: Renewable Energy Planning Database (REPD), Department for Energy Security and Net Zero, Open Government Licence v3.0, plus planning designation boundaries from planning.data.gov.uk (England only). REPD is published quarterly and covers schemes of roughly 150 kW and above. Capacity is the installed capacity on record, not metered generation. Operator is the operator of record at the last extract, not confirmation of present ownership. Reference 2540.
