What this site sits on
- Special Area of Conservation — Southern North Sea
REPD gives one representative coordinate per scheme, not the site boundary, so this describes the point on record rather than the whole site — a large site can straddle a designation edge. Boundaries come from planning.data.gov.uk, which publishes for England only.
How big is Hornsea 1 - Heron & Njord?
Hornsea 1 - Heron & Njord has a recorded installed capacity of 1.22 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 Hornsea 1 - Heron & Njord?
REPD records the operator as Orsted (formerly Dong Energy). 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 Hornsea 1 - Heron & Njord approved and built?
The application was submitted on 30 July 2013. Permission was granted on 10 December 2014, 16 months later. The site became operational on 1 December 2019, 60 months after consent.

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 2525.
