Overview
- The National Energy System Operator issued an Electricity Margin Notice forecasting a 1.4 gigawatt shortfall for the evening peak as a routine precaution.
- Power companies responded to the notice and increased available generation, reducing the projected shortfall to about 104 megawatts.
- NESO kept the margin notice in place as a contingency and said there is no risk to customer supplies and consumers do not need to take action.
- Forecasters expect a rise in wind generation overnight to further relieve the remaining margin gap, with gas generation acting as the short-term backstop when wind is low.
- Analysts and coverage note repeated weather-driven margin notices underline the need for substantial grid investment to integrate more wind and solar without recurring tight margins.
