Vitality big EDF has introduced plans to increase the lives of two of the UK’s 5 remaining nuclear energy stations.
Heysham 1 and Hartlepool had been as a result of shut in March subsequent yr, however they are going to now be saved open till early 2026.
The corporate says the transfer will help power safety, scale back demand for imported gasoline, and scale back carbon emissions.
About 1,400 individuals work on the two websites, with a whole lot extra within the provide chain.
The federal government welcomed the information, with Secretary of State Grant Shapps saying Russia’s invasion of Ukraine demonstrated the “important significance” of bolstering power safety.
Heysham 1 and Hartlepool started working in 1983. Every has two Superior Gasoline Cooled reactors, which had been initially scheduled for closure in 2014. Two earlier lifetime extensions had taken the closure date to March 2024.
The 2 energy stations presently account for about 5% of the nation’s electrical energy.
The announcement comes at a time when the nation’s power safety has been coming beneath intense scrutiny.
The majority of our electrical energy is generated from gasoline. Final yr, the battle in Ukraine led to a sudden spike in gasoline costs – which additionally led to a steep enhance in electrical energy payments.
Renewable era, from wind and solar energy for instance, has been rising quickly lately. However the quantity accessible to the grid can range in keeping with the time of day and the climate.
Supporters of nuclear era argue that it offers baseload energy – in different phrases, a predictable and steady provide – though different sources are wanted to react rapidly to spikes in demand.
To forestall potential blackouts this winter, 5 ageing coal vegetation have been saved on standby by Nationwide Grid.
Earlier this week two of them had been ordered to start out producing energy, as a mixture of excessive demand and restricted provides led to issues about attainable shortages.
A brand new scheme beneath which customers are paid to cut back consumption at peak instances has additionally been tried out not too long ago.
EDF mentioned the choice to maintain Heysham 1 and Hartlepool open had been taken following a “rigorous evaluate” of the technical and industrial instances for protecting them open.
It pointed to inspections of the reactor cores final yr which “elevated confidence that the stations can generate for longer and proceed to fulfill stringent regulatory requirements”.
The corporate has, nevertheless, closed three different nuclear energy stations over the previous 18 months.
Beneath present plans, even with the extensions agreed right now, the nation’s total fleet of AGR reactors is because of shut by 2028.
Sizewell B, a reactor constructed to a distinct design, is anticipated to stay open till 2035.
The federal government is dedicated to constructing a brand new era of nuclear energy stations. However just one – Hinkley Level C – is presently beneath development.
The brand new £25bn plant, which has been beset by rising prices and delays, shouldn’t be anticipated to open earlier than June 2027.
An professional group that features some vocal opponents of nuclear energy, the Worldwide Nuclear Threat Evaluation Group, mentioned in 2021 – in a report ageing nuclear energy vegetation – that extensions inevitably enhance the danger of accidents, together with the discharge of radioactive substances in to the atmosphere.
Heysham 1 and Hartlepool started producing energy within the Nineteen Eighties.
