Summary
The BSC currently suspends normal market operations following any Partial Shutdown of the Transmission System under the Grid Code. This is disproportionate for small, localised shutdowns.
Under P276, the BSC will only suspend normal operations following a Partial Shutdown if a specified Market Suspension Threshold is met. The intention of this threshold is to represent the point at which continuing the market may cause greater disruption to BSC Parties’ imbalance charges than suspending it.
Progression
National Grid raised P276 on 30 September 2011. A Workgroup assessed P276; both the Workgroup and the BSC Panel recommended approval. Ofgem approved P276 on 20 July 2012 for implementation on 31 March 2014.
