Energy massive EDF has launched plans to extend the lives of two of the UK’s 5 remaining nuclear power stations.

Heysham 1 and Hartlepool had been attributable to close in March subsequent yr, nevertheless they’ll now be saved open until early 2026.

The company says the switch will assist vitality security, in the reduction of demand for imported gas, and in the reduction of carbon emissions.

About 1,400 people work on the 2 web sites, with an entire bunch further inside the present chain.

The federal authorities welcomed the data, with Secretary of State Grant Shapps saying Russia’s invasion of Ukraine demonstrated the “essential significance” of bolstering vitality security.

Heysham 1 and Hartlepool began working in 1983. Each 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 two power stations presently account for about 5% of the nation’s electrical power.

The announcement comes at a time when the nation’s vitality security has been coming beneath intense scrutiny.

The vast majority of our electrical power is generated from gas. Last yr, the battle in Ukraine led to a sudden spike in gas prices – which moreover led to a steep improve in electrical power funds.

Renewable period, from wind and photo voltaic power as an illustration, has been rising shortly in latest occasions. Nevertheless the amount accessible to the grid can differ in response to the time of day and the local weather.

Supporters of nuclear period argue that it provides baseload power – in numerous phrases, a predictable and safe present – although totally different sources are wished to react quickly to spikes in demand.

To cease 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 out producing power, as a mix of extreme demand and restricted gives led to concerns about attainable shortages.

A model new scheme beneath which prospects are paid to reduce consumption at peak events has moreover been tried out recently.

EDF acknowledged the selection to take care of Heysham 1 and Hartlepool open had been taken following a “rigorous evaluation” of the technical and enterprise situations for conserving them open.

It pointed to inspections of the reactor cores last yr which “elevated confidence that the stations can generate for longer and proceed to meet stringent regulatory necessities”.

The company has, nonetheless, closed three totally different nuclear power stations over the earlier 18 months.

Beneath current plans, even with the extensions agreed as we converse, the nation’s full fleet of AGR reactors is due to shut by 2028.

Sizewell B, a reactor constructed to a particular design, is anticipated to remain open until 2035.

The federal authorities is devoted to establishing a model new period of nuclear power stations. Nevertheless only one – Hinkley Stage C – is presently beneath growth.

The model new £25bn plant, which has been beset by rising costs and delays, won’t be anticipated to open sooner than June 2027.

An educated group that options some vocal opponents of nuclear power, the Worldwide Nuclear Risk Analysis Group, acknowledged in 2021 – in a report looking at ageing nuclear power vegetation – that extensions inevitably improve the prospect of accidents, along with the discharge of radioactive substances in to the environment.

Heysham 1 and Hartlepool began producing power inside the Eighties.
