Lights will stay on this winter, grid operator says after concerns
The assurance from the National Energy System Operator comes amid concern from its engineers about their ability to ensure adequate supply.

The lights will stay on this winter, the body in charge of Britain's electricity network has said after concerns were raised by some of its engineers.
The National Energy System Operator (NESO) said the country's electricity system was prepared and "resilient to the challenges it may face" during the colder months.
However, its winter outlook report comes after an independent investigation found engineers had "high levels of stress and concern" about their ability to ensure adequate supply due to differences between renewable and gas-fired power generation.
However, there appear to be challenges in the transition to renewables in ensuring supply keeps up with demand, according to findings from an investigation into practices at NESO, which was commissioned following allegations over operational decision making and record keeping at the grid operator.
