Letter to the Hunterston Site Stakeholder Group - 10 June 2021

Dear SSG Member,

As a member of our community, I like to keep you updated on developments at Hunterston B power station.

On 5 June we brought Reactor 4 at Hunterston B power station back online following the permission to restart from the ONR. We brought the unit back to power following extensive graphite inspections; 45 fuel channels were inspected, the largest number ever in a single campaign. The results were well within the expectations set out before the inspections started.

This return to service marks the start of Reactor 4’s final period of generation; it will operate for a period of approximately six months, coming offline for the final time by 7 January 2022.

Since Hunterston B came online 45 years ago, it has generated enough low carbon electricity to power all of Scotland’s homes for 31 years. It has avoided more than 100m tonnes of CO2 being emitted into the atmosphere. That is like taking every car off Scotland’s roads for 19 years. It has been an integral part of the North Ayrshire community supporting the employment of thousands of people.

I am looking forward to a safe and successful final period of generation for the station before we move into the defuelling stage of the station’s life. I will continue to keep you updated on developments in this area at our meetings and by letter.

I hope this information is of use to you. If you have any questions please feel free to contact our External Relations Manager, Fiona McCall ( and she can arrange for you to speak to me.

Yours sincerely,

Paul Forrest

Station Director
