Problem Statement
Distribution Network Operators (DNOs) have reported that they are receiving a high volume of requests for Site Technical Details for Domestic and Microbusiness sites following a Switch or Change of Agent, resulting in increased workload for DNOs to validate and process these requests. It is not clear if these requests are all necessary or required by the MEMs and justify the effort required by the DNO to process these requests.

Proposed solution summary
- As an electricity consumer with an Advanced Meter, I want my usage data to be accessed remotely from my meter, to reduce the need for on-site visits and ensure that I receive timely and accurate bills.
- As the Market-wide Half Hourly Settlement (MHHS) Programme I want to see an effective, early migration of NHH settled Advanced Meters to HH settled, to reduce the risk of missed migration deadlines and ensuring sufficient time to resolve ‘problem’ sites ahead of the MHHS migration deadline.
- As an Energy Supplier I want to obtain usage remotely, reducing the need for on-site metering reading activity, enabling me to settle and bill accurately. As a Metering Equipment Manager (MEM), I need to understand any changes to obligations that may impact my business, so I can engage in the change process and plan any required changes to my systems, processes and organisation.

Problem Statement
The Balancing and Settlement Code (BSC) is seeking to mandate the Half-Hourly Settlement of Advanced Meters ahead of the transition to Market-wide Half Hourly Settlement. In order to support this transition, these meters will need to support remote communications to allow half hourly consumption data to be collected. There is currently no explicit requirement for Energy Suppliers and/or Metering Equipment Managers to ensure these meters have working remote communications, which could impact the successful migration of these meters to the new arrangements.

- As a MEM or a DNO I want clarity on how to deal with cable labelling during periods of coloured cable supply chain shortages, so that I can continue to install or maintain consumer metering.
- As a Metering Scheme Auditor, I want there to be clarity on the permitted labelling of non-standard colour coded cables used when connecting meters, so that audits can be appropriately completed.

Problem Statement
During times of sustained supply chain shortages, some colour coded cables may not generally be available. Where this is the case, Metering Equipment Managers (MEMs) and Distribution Network Operators (DNOs) need to be able to source a suitable alternative cable so that they can continue to install and maintain meters. Although the labelling of cables with different out sheath colours from the inner insulation is covered by the IET Wiring Regulations, this is not set out within the REC Electricity MOCoP.

Problem Statement
The implementation of REC V2, as part of the Retail Code Consolidation SCR, was due to consolidate the existing provisions in other codes into the REC on a like-for-like basis. The Code Manager has identified that there were changes made to previous codes that weren’t reflected in the REC V2 drafting that was implemented. This means that the current processes being operated by industry parties are not reflected in the REC. REC Party's and Service Providers rely on the REC to provide a consistent baseline to ensure the industry operate in an effective and interoperable way. There are currently inconsistencies between the drafting of the REC, and the processes operated by REC Party's and Service Providers, which could cause issues in the effective operation and assurance of the retail energy market.

The aim of this proposal is to reduce the extra assistance required by Electricity Market Reform (EMR) parties in the invoice validation by updating the backing data within the Market Messages to align to what is being invoiced. The associated Market Messages should be structured and named in line with the actual output of Settlement systems to facilitate validation of Capacity Market (CM) Scheme and the Contracts for Difference (CfD) financial settlement.

Proposed solution summary
- As an Energy Consumer, I want to be quoted the correct rates as part of my contract conversation when switching supplier. I want my meter set-up correctly to be able to utilise secondary electricity loads at specific times for specific purposes. (e.g., overnight Electric Vehicle (EV) charging, Heat/Hot Water, Boost, etc.). I want to be assured that I will have access to electricity when I need it. I want to switch to my chosen Supplier without any delays or issues.
- As an Energy Supplier, I need to identify meter types with Auxiliary Proportional Controllers (APCs) at a property, so that I can offer my customer the correct tariff and configure their meter correctly.
- As a Meter Equipment Manager (MEM), I need to identify meter types that incorporate Auxiliary Proportional Controllers (APCs) are present at a property, so that any necessary maintenance/repair work can be carried out appropriately.

Problem Statement
Currently there is no way to identify new meter types that incorporate Auxiliary Proportional Controllers (APCs) outside of the DCC Smart Metering Inventory. Failure to correctly identify these could result in an incorrect meter type being assigned to a supply point. Failure to accurately record where meter types that incorporate Auxiliary Proportional Controllers (APCs) are at a property could result in the meter not being configured correctly by the Supplier. This may impact switching, timely and accurately billing, and industry settlements. Options need to be considered to accurately record what meter types that incorporate Auxiliary Proportional Controllers (APCs) are installed at a property.

Problem Statement
BSC Modification P375 will be implemented on 30th June 2022 and introduces a new role of Asset Metering Virtual Lead Party (AMVLP), to allow settlement of meters ‘behind the boundary point’. To enable this, the AMVLP will need to exchange Market Messages with other Market Participants that underpin the new process being introduced by the BSC. Some of these Market Messages are governed by the REC and require a consequential REC Change Proposal to deliver the full solution.

Problem Statement
The successfully introduction of Market-wide Half-Hourly Settlement (MHHS) requires changes to made to the systems and processes governed by other codes outside of the BSC, including the REC. Elexon as the Senior Responsible Owner (SRO) and Ofgem as the Programme Sponsor for the MHHS programme need assurance that all programme participants will support the implementation of the programme and deliver against the approved timetable. While there is a general ‘duty to cooperate’ with Significant Code Reviews that exists for licenced parties, there is no explicit legal requirement for RECCo (as a non-BSC Party) to support this and no contractual recourse if its duties are not met.

Proposed solution summary
- As a market participant, I need to understand any changes to market messages I send and receive that may impact my business, so I can engage in the change process and plan any required changes to my systems and processes.
- As the REC Code Manager, I need to ensure that proposals to amend the Data Specification are subject to appropriate scrutiny and impact assessment, so that impacted stakeholders can appropriately engage with the proposal and understand the impacts to their business.

Problem Statement
The Data Specification was not included in the Switching Programme Change Requests that gave effect to REC V2.0. Therefore, the Data Specification was not formally designated as part of REC V2.0 and has temporarily been added to the REC Baseline Statement as a Category 3 product. This means that changes to the Data Specification, including changes to Market Messages and Data Items used by market participants to interface with other businesses and service providers, are not subject to the process set out in the REC Change Management Schedule. Changes to these artefacts can have significant impacts to the systems and processes of market participants and service providers. These changes should follow a robust and thorough assessment to ensure these impacts are identified and considered, and the most appropriate solution is considered. The Category 3 change process is not appropriate for this, as changes to Category 3 products should not cause a material impact to parties and stakeholders.

Problem Statement
SEC Modification Proposal 077 proposes to update the values, and business rules, of the DCC Service Flag Data Item. This will allow users to use the Data Item as originally intended, to establish whether there is an active smart meter in the DCC network that they can communicate with at a premises. This modification has been approved for implementation on 4th November 2021 by the SEC, and a consequential change is required to the Data Specification to reflect this.
