The UK is expected to have sufficient power supply this winter, with the National Electricity System Operator (Neso) stating that there will be more than enough power from various sources to meet demand. Neso’s winter outlook predicts an average margin of 5.2 gigawatts (GW) between supply and demand, an improvement from last year’s 4.4 GW. This increased margin is attributed to enhanced capacity, including the newly operational Viking Link interconnector connecting the UK with Denmark.
The UK’s electricity network now has more battery storage capacity and interconnected generation capacity, compensating for the closure of some power plants such as Ratcliffe-on-Soar, the last coal-fired plant in the UK. Neso anticipates being a net importer of electricity from mainland Europe this year, ensuring close cooperation with European system operators for a secure power supply. Despite this, Neso foresees ‘tight days,’ during which it will utilise tools like system notices to manage supply-demand imbalances.
Craig Dyke, Neso’s director of system operations, highlighted the importance of monitoring risks and uncertainties to maintain system resilience. An emphasis will also be placed on the Demand Flexibility Service (DFS), which incentivises consumers to reduce electricity usage during peak times to alleviate pressure on the grid. Additionally, National Gas, responsible for the gas system, reassured that supply options, including UK, Norwegian, and interconnector sources, are robust for meeting winter demand.
Both Neso and National Gas remain vigilant about ensuring a stable power supply throughout the winter season, aiming to address any challenges proactively. The collaboration between energy system operators and consumers’ participation in demand management schemes are crucial components in maintaining a reliable energy system amidst changing demand patterns and supply dynamics.
