This Modification will reduce BSC costs to Suppliers for entering domestic and small non-domestic customers into elective Half Hourly (HH) Settlement and could encourage Suppliers to promote such Settlement on a larger scale. This will help meet the intentions of Ofgem to increase HH Settlement across the market, improving Settlement accuracy and promoting innovation into the market.

The proposed solution is to amend the method by which the ‘Supplier’ half of the SVA Costs are recovered so that all of these costs are recovered through a single ‘per Metering System Identifier (MSID)’ fixed tariff.


British Gas (the proposer) raised modification P346 on 23 June 2016 as agreed at stakeholder group following direction from Ofgems’ review of Half Hourly (HH) Settlement.

P346 was approved by BSC Panel 259 for implementation. The Panel also agreed that P346 meets the Self-Governance criteria.

P346 was implemented on 1 April 2017.
