The Guardian | Storm Bella helps Great Britain set new record for wind power generation

Due to Storm Bella, on Boxing Day, more than half of the country’s daily electricity came from wind turbines. However, the reliability of wind energy is a concern.

Our research shows that the electricity system operator increased its reliance on gas-fired power plants by 20% in September compared with the year before. This was amid a slump in renewable energy generation.

“To compensate for the lower wind speeds and dunkelflautes – dark, still periods – we turned to gas and coal,” he said. “It’s part and parcel of relying more on weather-driven capacity and interconnector exports, which makes us more reliant on the vagaries of the wind and sun.”
