Lights will stay on this winter, grid operator says after concerns

What happened: The National Energy System Operator said Britain's electricity system is prepared for winter and "resilient to the challenges it may face," while warning of possible "tight days." The assurance followed an independent investigation into NESO's control room practices. Key numbers: Why it matters: The Eversheds Sutherland investigation found "high levels of stress and concern" among control room engineers about balancing supply, and a "significant disconnect" with NESO leadership. It did not substantiate whistle-blower allegations but identified cultural and governance issues.
