Capacity provenance

The public capacity above is the current source-record value. A 2026 tracker candidate lists 1,258 MW for Seabank power station, but it is not used as the public primary value until scope is verified (unit vs operating vs installed/project total).

Data provenance

The capacity and/or fuel fields on this page include a source-backed provenance label from GEM, an official registry, Wikidata, OSM, or a cross-source match.

In context: how this plant compares

At 812 MW, Seabank 1 is well above the median gas plant in United Kingdom (115 MW). Its current lifecycle status is “Pre Construction” — so it is not yet, or no longer, generating at full output. Gas plants burn natural gas either in open-cycle turbines for fast peaking, or in combined-cycle units that recover exhaust heat in an HRSG to reach roughly 55–62% efficiency — the cleanest-burning fossil option.

Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.
