Balancing and Settlement Code (BSC) modification proposal P485 was raised on 19 March 2025 by Scottish Power. The proposed modification seeks to freeze the transmission loss factors (TLFs) used to calculate Balancing Services Use of System charges at 2024-25 levels for the BSC year 2025-26, until a full investigation on the reasons behind the changes seen year on year is concluded. Once the investigation is complete and TLF values for 2025-26 confirmed, charges from 1 April 2025 onwards would be reconciled using the confirmed TLFs.
On 19 March 2025, the BSC Panel requested that the proposal be treated as urgent based on our urgency criteria. We have granted this request. The attached letter sets out our reasoning for approving the request.
