Outcome of request for an urgent review of proposed changes to Balancing and Settlement Code, P509 Consumer benefits and safety net for Demand Side Response participation in the wholesale market.
Details of outcome
We have decided to reject urgency for Balancing and Settlement Code (BSC) modification proposal P509.
Code modification description
P509 was raised by Voltalis on 5 March 2026. P509 proposes that Elexon undertake regular benefit assessments and publish aggregated insights on Demand Side Response performance. If repeated negative net impacts are identified, the framework would provide appropriate governance, escalation arrangements and regulatory oversight.
At the BSC Panel on 12 March, Voltalis requested urgency in light of information showing that there has been a recent increase in the volume and cost of the P415 mutualised compensation fund. Related code modifications P510 and P511 also requested urgency on similar grounds.
The BSC Panel did not agree to recommend to Ofgem that P509 should be progressed as an urgent modification proposal.
We have considered P509 alongside the related urgency requests for P510 and P511. We have decided to reject the request for urgency for P509. This letter sets out our reasoning.
