Addressing Challenges in Supplying Data for DCC Charging

Issue Overview: Challenges to the data being supplied by Xoserve to the DCC for charging purposes Overview: From October 2020, in accordance with a related Data Permissions change to the UNC, Xoserve have supplied a dataset of Non-Domestic Supplier Market Share data to the Data Communications Company (DCC). Xoserve are aware that the datasets being provided to DCC are not aligned with market share information held within Supplier systems, and that this is resulting in greater than anticipated DCC charges to Supplier businesses. Provide background on the changes that Xoserve have made Clarify the logic being applied to retrieve the data we are supplying to DCC Clarify our understanding of DCCs position with respect to charging Suppliers Seek input from Shipper customers on how best we can correct this reporting logic Purpose

Background of Changes That Have Been Made Previously, Gas Suppliers for non-domestic premises would only be charged by the DCC for sites that had SMETS2 meters enrolled A recent BEIS-driven change to the SEC Charging methodology has widen the chargeable meter base from domestic mandated meters to include non-domestic mandated meters During development of the DCC Charging methodology, it was confirmed that Non-Domestic, Advanced Meters should not contribute to a Supplier s DCC Charge. In order to ensure DCC had discounted a Suppliers non-domestic, Advanced Meter market share when calculating their charges, a Data Permissions change was introduced into the UNC This placed responsibility on the CDSP to provide certain data to the DCC The requirements and logic Xoserve proposed to use to satisfy this data request and associated UNC Data Permissions change were presented to CoMC in September 2020 for approval The reporting logic aligns to the UNC requirements, ensuring that counts of MPRNs per Supplier are shared with DCC on a monthly basis to the agreed timescales, including only sites that; a) Have non-domestic status - based on Market Sector Code b) Have an Advanced Meter based on the AMR Indicator which is recorded in UK Link c) Have an AQ of 732,000kWh or less

What Issues have been Identified? In recent months, Xoserve have received multiple queries from Shippers on the charges now being charged by DCC to your Supplier businesses We have been made aware that a number of exemptions exist within the Supplier License that would exclude Large Gas Meters or microbusinesses from having Designated Premise status These exemptions are not currently being included within the datasets supplied to DCC relating to a Suppliers non-domestic, Advanced Meter market share, as recorded within UK Link Xoserve have engaged with DCC and are seeking to address the gaps in reporting logic that are leading to incomplete Supplier Market Share data being supplied to the DCC DCC have confirmed they can only charge based on the information available, and that they have a dependency on Xoserve to continue to provide datasets in line with the current obligations DCC have confirmed they are able to perform invoice adjustments once more appropriate datasets can be created and shared In order for Xoserve to make the necessary changes to the reporting logic, a number of questions exist that require Shipper input

Questions for Shippers 1. Are there other attributes we could / should be using to distinguish presence of an Advanced Meter? Embedded AMR are these identified in UK Link as AMR? Are Meter Models discrete? SMSO ID do all AMR devices operate with an SMSO and are these details populated in UK Link? 2. Micro-Business sites are these identified in UK Link as Non-Domestic? 3. Large Gas Meters are these only present on Non-Domestic premises? 4. Report logic, based on BEIS request, limits the AQ threshold to 732,000kWh and below should we be including all non-domestic MPRNs given those above that threshold? 5. Do other exemptions exist that would require meter points to be included within the datasets we are sharing with the DCC?
