Summary
Electricity Suppliers believe there is a significant bottleneck to Export Metering Point creation, which is resulting in them feeling unable to offer Export smart products to a wider audience of Consumer and scale low-carbon technology. The most effective solution is an API within the Electricity Enquiry Service (EES) that allows the Electricity Supplier to request the creation of an Export Metering Point. This could work for both Electricity Suppliers and Distribution Network Operators (DNOs) ensuring that scalable solutions are applied at both sides of the process.

Problem Statement
A restriction of 50 Export Metering Points per DNO per day, with no two DNOs operating the bulk request process in the same way, is overly burdensome to Electricity Suppliers and creating a barrier for Consumers getting an Export Metering Point assigned to their Premise. This is ultimately harming the effort the reach Net Zero.

22/09/25 - This Change Proposal has been implemented as part of the MHHS M8 22 September 2025 REC Release.
Summary
The Electricity Smart Meter Equipment (ESME) ID is a unique identifier that provides a designation for a Smart Meter. Electricity Retail Data Agent (ERDA) systems were updated as per the requirements in R0033 to not allow for multiple incidences of an individual ESME ID to be registered, and reject the update, even when a second incidence of an ESME ID would be legitimate, for example in the case of a re-use of Metering Asset or a crossed meter. This Issue seeks to resolve this feature of the ESME ID validation while maintain data accuracy.

Problem Statement
ERDA data validation on the ESME ID Data Item in the D0312(MM00256) Market Message is imperfect, and can result in invalid rejections. This occurs when more than one incidence of an ESME ID is passed through individual ERDA system, as it only allows for a single occurrence, even if historic ones have been end-dated. In situations where a Metering Asset has been re-used, thus re-using the ESME ID, a rejection will occur, in an example of an unintended functionality of the validation system.

Latest Update
08/11/2024 - This Change Proposal has been implemented as part of the November 2024 REC Release.
Summary
This is a Housekeeping Change Proposal subject to the Housekeeping Change Proposal process, rather than the standard Change Process. The nature of the change is that it makes non-material changes to the REC Products to correct typographical, grammatical or consistency errors, and provides an opportunity to introduce necessary clarifications. This change proposal is looking to fix an error identified with R0206 Cross code change to align with BSC CP1598. BSC CP1598 was raised to add six scenario variants to four Market Messages that have been identified as missing. The REC Energy Market Data Specification contains a number of Market Message scenario variants used in BSC processes. This REC Change Proposal has been raised to align with CP1598 and ensure these scenario variants are added to the REC Data Specification. The legal text for R0206 approved at Change Panel on 15 October 2024, had a change to one of the scenario variants (SV00474) that was not clear as it was not red lined. The change was to the owner of the scenario variant from the Retail Energy Code Company (RECCo) to the Balancing and Settlement Code Company (BSCCo). The red lining for SVcccc was also incorrect as it deleted RECCo as the owner when in fact it is a new scenario variant so no previous owner. The owner as BSCCo that was approved, is correct.

Summary
BSC Mod 459 and REC CP R0144 were raised to allow different MOAs to be appointed for the import and export MPANs on a shared meter. One of the justifications for this was to stop export suppliers being charged inflated rates. Both changes have been placed on hold due to the MHHS Programme so this change has been raised to specifically resolve the charging issue.

Problem Statement
Where the same electricity Metering Asset is being used for the measurement of Import and Export for more than one Metering Point, the Export MOA must be the same as the Import MOA. This may result in uncompetitive charging by the MOA, as the Export Supplier has no choice in their appointment.

Problem Statement
As these Scenario Variants are not captured in the Data Specification, the relevant Market Participants won’t be able to use the Data Transfer Network (DTN) to exchange the relevant data, which would result in them having to use a less secure mechanism to send and receive data. This means the original intent of Elexon Modification P375 has yet to be achieved as not all Market Message changes have been implemented.

Provision of Half-Hourly Consumption Data for Advanced Meter Erroneous Switches

Latest Update
This Change Proposal was implemented as part of the 7 November 2025 REC Release.
Summary
As part of the MHHS REC code change activity, a change has been made to REC Schedule 30 to remove the half hourly meter exemption from the Erroneous Transfer provisions. Whilst this is necessary from an MHHS perspective with all sites becoming half hourly settled, the application of ET obligations in the Advanced Meter segment creates some additional challenges. To be able to accurately bill an Advanced Meter site, following repatriation of that customer to their correct supplier after an ET has been raised / agreed, the supplier needs to have access to half hourly consumption data for the ET period when they were not the registered supplier. With ETs potentially taking up to 2 years to be identified and resolved, the only place that the supplier could reliably source that HH consumption data would be from the other (losing) supplier.

Proposed solution summary
- An approval of this Issue/Change Proposal would see an obligation placed upon the Losing Supplier, following a successful Erroneous Switch repatriation, to provide the Gaining Supplier with the Half-Hourly consumption data for the period in which they were erroneously supplying the meter.
- Half-Hourly consumption data would be providing to the Gaining Supplier, from the Losing Supplier, via SDEP using an Excel template within 5 Working Days of the Erroneous Switch repatriation switch date. The Gaining Supplier would be required to provide 48 Half-Hourly consumption intervals for each that the the Consumer was supplied by the erroneously Gaining Supplier.
