Station timeline
These timeline entries highlight the main milestones for the site, including commissioning, major changes, closure and current status where relevant.
2012Commissioned
Entered service as part of the UK gas fleet.
2025Operational snapshot
Listed as operational at the end of May 2025 in DESNZ DUKES 5.11.
2026Grid role
Gas stations remain important for balancing, reserves, and covering demand when low-carbon output varies.
Reading the landscape
Power-station siting reflects engineering requirements, fuel and water logistics, grid access, industrial geography and the planning frameworks of the period in which the site was developed. Pembroke should therefore be read as part of a wider infrastructure system rather than as an isolated structure in the landscape.

Gallery notes
These notes highlight the main structures, layout characteristics and historic changes associated with the station. They are intended as a concise interpretive layer alongside the reference data, timeline and technical diagrams.
Plant language
Boxy turbine halls, HRSG stacks, transmission yards and river or estuary siting are all part of the gas station visual grammar.
How to read it
Look for intake systems, gas turbines, heat-recovery equipment and large grid compounds rather than cooling towers.
Grid role
Most modern gas stations are valued for dispatchability and response, not just raw annual output.
