Two new balancing services have been developed to support National Grid in balancing the system during the mid-decade period when capacity margins are expected to tighten. The new services are Demand Side Balancing Reserve (DSBR) and Supplemental Balancing Reserve (SBR).
DSBR is targeted at large energy users who volunteer to reduce their demand during winter weekday evenings between 4 and 8 pm in return for a payment. SBR is targeted at keeping power stations in reserve that would otherwise be closed or mothballed. These services will act as a safety net to protect consumers, only to be deployed in the unlikely event of there being insufficient capacity available in the market to meet demand.
These new balancing services were developed during the latter half of 2013 through an industry consultation process, and these products were approved by Ofgem on 19th December 2013. Ofgem’s decision letter was published on their website. Market information associated with these services is published below:
