30/03/2026 The Proposer has withdrawn this Issue following discussions with industry, where impacted Parties advised waiting for the completion of MHHS migration before progressing this Issue and solution development. The window to adopt this Issue has now closed.
Summary
There is a concern regarding shared sites (as defined by BSCP550) that have multiple suppliers linked to them. The investigation revealed a lack of visibility of these sites, and it appears that the industry is similarly uninformed. Elexon, the REC, and the wider industry do not have a consistent way of identifying these shared sites. Therefore, there is a good chance that agents are holding shared sites within their portfolio without knowing it. We would like to explore whether the EES Online Portal has any flags or mechanisms that could help identify these shared sites.

29/04/2026 - This Issue has been withdrawn by the Proposer, as there was not a strong preference amongst MAPs of which temporary solution option (if any) should be progressed. Many MAPs already have workarounds in place, and a permanent solution is expected to be progressed in the future through a joint REC / BSC change. The adoption window has closed.
Summary
As part of Market Wide Half Hourly Settlement (MHHS) design, the requirement to provide Data Item Effective from Settlement Date {REGI} (J0049 / DI50025) in the Notification of Meter Operator, Supplier and Metering Assets installed / removed by the MOP to the MAP Market Message (D0303 / MM00240) has been changed from mandatory to optional. This means Meter Asset Providers (MAP) may not receive it.

Problem Statement
The Effective from Settlement Date {REGI} Data Item being optional rather than mandatory inside the Notification of Meter Operator, Supplier and Metering Assets installed / removed by the MOP to the MAP Market Message means that MAPs may not receive this information required for billing purposes.

Problem Statement
The example responses detailed in section 4.2 are broken down as ‘mprn’ with three demoed data items; ‘mprn’, ‘installation name’, and ‘network name.’ this is however not reflective of the correct responses that would actually be returned on an API call. The actual structure is ‘supplier’ with the demoted data items actually being ‘amr_indicator’, ‘amr-sp’, and ‘csep_id.’ Fundamentally, this would mean that users are consuming incorrect information when looking to this document for guidance. This could potentially be causing negative impacts when the document is relied upon, especially for newer users seeking guidance.

04/06/2026 - on 02 June 2026, the Technical Expert Panel approved via ex-committee vote to place I0228 on hold, until the outcome of R0321 is known.
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.

18/03/2026 - An update to plan has been published for consideration at the Technical Expert Panel on 25 March 26.
Summary
As part of the impact assessment process for R0115, it was identified that it is very costly and time consuming to make reporting changes within the CSS architecture. As such, we would like to explore enabling agile reporting within the CSS ecosystem, by creating a functionality that consolidates all necessary data into a single, centralised database.

Problem Statement
Current CSS arrangements mean that REC Changes designed to facilitate access to CSS data are more onerous that they need to be. Current arrangements are costly and have relatively long lead-times. This Issue seeks to explore changing the way that the CSS data can be accessed.

Summary
Housing Associations require an understanding of the equipment installed in each of their properties as well as managing empty properties. They are also wanting to take a bigger role in supporting their tenants (with their consent) in managing their energy use. If provided with industry data, housing associations can provide targeted information to their tenants and help them make informed choices about their metering system, manage empty properties as well as understand the equipment within the properties they own.

Summary
The Third-Party Service Provider Non-Switching category is a new EES User Type for organisations providing services to generators or end-users for purposes other than Switching. One such organisation is a provider of a platform for Microgeneration Certification Scheme (MCS) installers to simplify the way in which renewable installation applications are submitted to Distribution Network Operators (DNOs). Access to MPANs will enable the installer to cross-reference with details provided by the customer to ensure accurate data it provided to the DNO for the connection of the generation system. It will also assist in identifying the correct meter point in conversion properties. The DNO application for the connection helps the customer receive an export MPAN and the confirmation of a smart meter and who the Supplier is supports a smooth customer journey in setting up export tariffs.
