On Tuesday 28th October 2014 SSE agreed a one-year contract with the National Grid to provide, through the recently introduced Supplemental Balancing Reserve (SBR) service, backup reserve of up to 780MW of capacity from its Peterhead power station in Aberdeenshire.
On Wednesday 5th November Peterhead will carry out a one-off non-proving run as permitted under the terms of its SBR contract. The run has been approved, and will be facilitated, by National Grid.
The plant will generate throughout the day, gradually increasing its output until the evening peak period when it will generate at 740MW for just over two hours. Once this non-proving run has been completed, Peterhead will remove itself from service and be unavailable to the market unless called upon by National Grid, in accordance with the terms of its SBR contract.
