View pageKey facts about Great Britain power market
Great Britain operates as a single synchronous system with strong interconnectors to France, the Netherlands, Belgium, Norway, and Ireland.
The generation mix has shifted rapidly toward wind, while gas and interconexions remains the main flexible sources for balancing.
Offshore wind is a major driver of price volatility and can create extended periods of low prices.
Demand peaks typically occur in winter evenings due to lighting and heating, creating strong seasonal price sensitivity.
Great Britain participates in coupled European markets, so cross-border flows can materially affect price formation.
