On 10 June the BSC Panel approved the Market-wide Half Hourly Settlement (MHHS) Implementation Charge for 2021-22. The new charge, introduced under modification P413 Market-wide Half Hourly Settlement Programme Manager, will cover Elexon’s programme management costs for MHHS implementation. It will be levied on suppliers on a monthly basis, based on the number of Supplier Volume Allocation metering systems that the supplier is the registrant for at the start of each month.
Elexon has proposed a budget for programme implementation over the planned five year timescale. As shown in the chart, the 2021-22 budget is proposed to be ~£14.55mn, peaking in 2022-23 at ~£18.9mn, and remaining steady until 2025-26 where costs only run until the expected completion date of October 2025.
