The regulatory body overseeing the energy network in the UK has issued a plea to energy companies as the nation experiences a heatwave. A red warning for extreme heat has been put in place in certain areas of England and Wales until 9 pm on Thursday. Temperatures are expected to reach up to 37-38C in southern England, with a possibility of hitting 39C.
The soaring temperatures have led to a surge in the purchase of fans and air conditioning units by individuals and workplaces to combat the heat. This spike in demand for electricity has been exacerbated by warm overnight temperatures, making it difficult for many to get a restful night’s sleep even with cooling appliances running.
In response to the increased demand, the National Energy System Operator (NESO) issued an Electricity Margin Notice to power station owners, requesting additional supplies to prevent power shortages. NESO emphasized that this action is a routine precautionary measure to manage the risk of power cuts due to high electricity demand anticipated for the evening.
NESO highlighted that the UK’s electricity demand is nearing its supply capacity, partly due to soaring temperatures in Europe affecting electricity imports and reduced output from wind farms. The heatwave has prompted health warnings, school closures, and transportation disruptions, with classrooms in several regions closing early due to the extreme heat.
According to a NESO spokesperson, the tight electricity margins are a result of the intense heatwave affecting Great Britain and Europe, coupled with low wind conditions. The Electricity Margin Notice is a standard protocol to mobilize additional generation capacity without indicating an imminent risk to electricity supply.
Earlier in January, NESO issued a similar alert due to exceptionally cold weather, which was expected to increase electricity consumption as people stayed indoors and used heating systems.
