Terra Firma Energy – 17 November 2025

This announcement follows the amber cold-weather health alert issued by the UK Health Security Agency, as reported by Sky News, with temperatures forecast to fall as low as –7°C in parts of the country and potentially –10°C overnight.

Early and severe cold spells typically drive a sharp increase in electricity demand, while also heightening volatility in wholesale power markets when renewable output dips and system margins tighten. These conditions place greater reliance on the UK’s flexible generation fleet to keep supply and demand balanced.

In preparation, TFE has completed an accelerated maintenance and readiness programme across all operational sites, ensuring each plant is fully optimised for rapid response, cold-start performance and sustained winter operation.

This includes:
– Full mechanical, electrical and control-system inspections across the fleet
– Cold-weather readiness work covering cooling circuits, auxiliary heating, and freeze-risk mitigation
– Enhanced remote monitoring, diagnostics and 24/7 visibility improvements

Zach Dodds-Brown, Development Director, Terra Firma Energy commented:

“With winter arriving earlier and colder than expected, the UK energy system will rely more heavily on flexible generation to support security of supply. Thanks to our pre-emptive maintenance programme, and our close coordination with EDF (UK) as our optimisation partner, Terra Firma Energy enters this winter in a strong position to deliver reliable, responsive capacity when the grid needs it most.”
