Change Consultations

CEPA and Elexon have issued a Call for Evidence to gather stakeholder views on the potential benefits, costs and other impacts of implementing P462 The removal of subsidies from Bid Prices in the Balancing Mechanism.

This Modification proposed the removal of Section K3.1.2A from the BSC to reflect how Exemptions for Electricity-Intensive Industries (EII) are applied in practice. The current Department for Business and Trade (DBT) led process already accounts for mixed asset configurations within BM Units, rendering this BSC restriction outdated. With no industry impacts, low implementation costs, and alignment with operational and policy intent, this change will simplify the Code and remove a point of potential non-compliance.

Under the MHHS Programme there is currently an incentive for Suppliers to become qualified to participate in the new arrangements by Milestone 14. This Modification seeks to replicate that incentive for Milestone 15. This proposal aims to incentivise Suppliers to meet the MHHS Migration Plan by restricting their ability to register new Metering Systems if they fail to complete migration on time. 

This Modification seeks to address this issue by removing the Half-Hourly settlement requirement for associated Boundary Point Metering Systems. Doing so will expand access to flexibility markets for domestic consumers, support equitable participation in energy services, and reduce the dependency on Market-wide Half-Hourly Settlement (MHHS) for consumer inclusion. This change is expected to enable flexible asset participation and support energy system goals such as Clean Power 2030.

This Urgent Modification proposes that, until the BSC Panel’s determination that 2025/26’s Transmission Loss Factors (TLFs) reflect expected changes in variable losses due to marginal demand or generation changes as anticipated when BSC Modification P350 was approved, TLFs from the 2024–25 BSC Year will apply to the 2025-26 BSC Year from the P485 Implementation Date.

The Panel must decide what TLF values, the ‘corrected values’, to apply. The Panel are consulting on two solution options. Under the Proposed, the ‘corrected values’ will be applied from 1 April 2025. Under the Alternative solution, the ‘corrected values’ will apply from the BSC Season following the Panel determination.
