UK wind generation in September reached 6.62 TWh, a September record and up 4% YoY, cutting gas-fired output to the lowest September level on record.

UK wind generation in September reached 6.62 TWh, a September record and up 4% YoY, cutting gas-fired output to the lowest September level on record.

The rise in wind supports the UK's move toward a largely decarbonised power system by 2030, but the market remains highly exposed to gas-price swings: even with a smaller gas share, gas frequently sets marginal prices during key daily hours.
