P379 ‘Multiple Suppliers through Meter Splitting’
Formal title: Enabling consumers to buy and sell electricity from/to multiple providers through Meter Splitting
This Modification will enable consumers to be supplied by multiple Suppliers through Balancing and Settlement Code (BSC) Settlement Meters at the Boundary Point. P379 will allow multiple Suppliers to compete for the supply or export of electricity through a single Meter without needing to establish an agreement between all of the Suppliers involved for every instance.
P379 aims to address a significant barrier to competition in the market rules whereby multiple Suppliers are unable to compete for behind-the-meter energy volumes, measured via the same boundary Metering System. Whilst the existing SVA Shared Metering Arrangements do facilitate splitting of boundary Metered volumes between different Suppliers, these arrangements are restrictive, for example they require agreements in advance between the Suppliers. The Proposer believes that the existing arrangements don’t adequately facilitate the development of local energy markets and supply innovation, and effectively mean there is a monopoly of one Party, the ‘default’ or ‘Primary’ Supplier, over a consumer’s energy volumes behind a Settlement Meter at any given time, restricting competition and innovation.
This Modification was raised by New Anglia Energy, a new BSC entrant, with support from a range of BSC Trading Parties including OVO Energy and Cooperative Energy, and non-BSC parties, including Powervault and Verv. The original P379 Proposer, New Anglia Energy, withdrew P379 on 26 February 2020, noting that the withdrawal was related to other business commitments and not the proposal itself. GridBeyond adopted P379 on 26 February 2020 and are now the P379 Proposer. Further details can be found in the second Interim Report.
As per ELEXON’s communication concerning the impact of COVID-19 the timeline for P379 has been pushed back 3 months. While we are presenting the scope of the CBA on 14 May 2020 we don’t intend on issuing the CBA to industry at the moment.
P379 Cost Benefit Analysis
At the March BSC Panel meeting, the Panel requested that ELEXON carry out a cost benefit analysis to determine the merits in continuing with Modification P379. ELEXON will present the cost benefit analysis scope at the May Panel meeting.
P379 Interim Assessment Report – Extension Request
The Panel approved an eight month extension on 12 March 2020, to allow ELEXON to conduct a cost benefit analysis (CBA) for P379. ELEXON will provide an update to the Panel on 14 May 2020, including the scope of the CBA. ELEXON are engaging with Ofgem about the CBA and are planning to hold a workshop with interested parties to help inform the CBA.
The last P379 Meeting (WG12) was held on 3 February 2020. The Workgroup reviewed the Business Requirements and the P379 calculation processes. The Business Requirements can be found as an attachment to the second Interim Report.
The First P379 Interim Assessment Report was presented at the BSC Panel meeting on 13 June 2019. A copy of the Report can be found in the Documents section below.
P379 was raised on 3 January 2019, and the Initial Written Assessment (IWA) was presented to the BSC Panel at its meeting on 10 January 2019. The Panel progressed P379 to the Assessment Phase.
