CMP373 'Deferral of BSUoS billing error adjustment'

On 9 April 2021, the ESO informed industry parties that they had underbilled BSUoS by ~£44m of Balancing Services costs incurred in 2020/21 made up of costs associated with trading activities and the Accelerated Loss of Mains Change Programme (ALoMCP).​ The Proposer is content with the approach for recovery of ALoMCP (~£10m). However, the ESO have proposed to recover the cost associated with trading activities (~£34m) through the Reconciliation Final run (RF) for 2020/21, which the Proposer believes will cause significant problems for Suppliers, Generators and Consumers.
