Amid scorching temperatures in the midst of a heatwave, the regulatory body for the UK’s energy infrastructure has issued a plea to energy providers.
An uncommon red warning for extreme heat has been activated in select regions of England and Wales, set to remain in effect until 9 pm on Thursday.
Weather projections indicate temperatures climbing to approximately 37-38°C in southern England, with a peak of 39°C not ruled out.
The soaring temperatures have led to a rush for fans and air conditioning units by individuals seeking relief from the heat, both at home and in workplaces, resulting in a surge in electricity demand.
The situation has been exacerbated by tropical-like overnight temperatures, causing many to struggle with sleep even with cooling devices in operation.
Responding to the escalating demand, the National Energy System Operator (NESO) issued an Electricity Margin Notice on Tuesday.
This directive requires power station owners and other generators to enhance supplies if necessary to avert the risk of power shortages. The peak demand is anticipated later today.
While NESO describes this as a standard procedure, it signifies a warning that the UK’s electricity demand could soon surpass supply levels.
The alert is compounded by sweltering conditions across Europe, hindering the UK’s ability to import electricity, along with reduced wind affecting output from wind farms.
The heatwave has prompted a rare red health warning, resulting in school closures and transportation disruptions. Some classrooms have become too hot to function, leading to early closures in various regions.
A spokesperson from NESO stated, “Our forecasts indicate a tight electricity margin for tomorrow evening due to the extreme temperatures affecting Great Britain and low wind conditions.
“An Electricity Margin Notice (EMN) has been issued to the market, requesting additional generation capacity from market participants. This measure is precautionary and does not imply imminent electricity supply risks,” they reassured.
NESO had previously issued a similar alert in early January, then due to plummeting temperatures expected to raise electricity consumption as people stayed indoors and used heating systems.
