From the 1st April 2018 we will be reducing the TEC at Peterhead to zero. The cancellation of our TEC at this time is a risk mitigation measure to avoid a substantial cancellation charge if we were to cancel later in the year, once we have completed our review of the stations future, which we announced on 6 February 2017. We will reapply for TEC and subject to receiving a satisfactory offer from NGET, reinstate TEC should our review conclude that the station has an enduring future.
