    About HyDeploy

    HyDeploy is a partnership between Northern Gas Networks, Cadent, the Health and Safety Executive, Keele University, ITM Power and Progressive Energy.

    HyDeploy is carrying out vital demonstrations to show that the gas network can carry a blend of hydrogen with no impact on the customer’s gas supply. It is providing evidence on how customers don’t have to change their cooking or heating appliances to take the blend, which means less disruption and cost for them. It is also confirming initial findings that customers don’t notice any difference when using the hydrogen blend.

    The HyDeploy project began with a first phase live demonstration of blended hydrogen and natural gas on part of the private gas network at Keele University campus in Staffordshire.

    The second phase of the project involves 668 domestic properties in the Northern Gas Network.

     

    The HyDeploy phase 2 project is now in its final phase

    This follows 11 months of successfully blending hydrogen into a small section of a live network in Winlaton. This involved 668 mainly domestic consumers.

    Northern Gas Networks processed Voluntary Customer Payments across a portfolio of approximately 20-30 different Suppliers

    Payments were made through existing industry data flows and caused very few exceptions.

    Supported HyDeploy during unprecedented volumes of Supplier of Last Resort (SoLR) transfers

    Alongside Northern Gas Networks, we’ve worked with stakeholders to reduce the impact of SoLR transfers to consumers taking part in the HyDeploy phase 2 trial.

    We’re now reverting industry processes back from the temporary arrangements

    Blending hydrogen into the gas network ends on 30 June 2022. We’re now reverting industry processes back to the usual arrangements as the project ends.

    We’ll continue to update industry stakeholders as we carry out these changes to the central systems.

    How Northern Gas Networks prepared for the demonstration

    Joanna Ferguson, Head of Market Services & Regulatory Compliance at Northern Gas Networks, explains how her organisation prepared for HyDeploy. 



    Xoserve’s role in the HyDeploy demonstration

    We're working closely with stakeholders across the industry to deliver HyDeploy in a transparent manner operationally.

    We're responsible for ensuring the data infrastructure underpinning the transformation is fit for purpose, effective and scalable. This ensures the infrastructure could be adopted for similar projects in future.  

    As the Central Data Service Provider (CDSP), we ensured all Meter Point Reference Numbers (MPRNs) included in the second phase were readily available. We also established processes and controls to protect these MPRNs (and consumers) from being adversely impacted during the demonstration.

    Process information for Xoserve customers

    Introducing hydrogen into the live gas network may have an impact to the calculation of energy. This has implications on the Annual Quantity (AQ), procurement and reconciliation charges – meaning process changes for Networks, Shippers and Suppliers.

    There are process changes required to ensure a successful outcome of the HyDeploy North East demonstration:

    • An indicator will be applied to UK Link, Data Enquiry Service (DES) and Data Discovery Platform (DDP) to provide Shippers and Suppliers visibility of the Meter Point Reference Numbers (MPRNs) included within the demonstration.
    • An AQ Backstop date will be applied to all MPRNs in the demonstration from 1 September 2021. This will prevent any changes to the AQ during the demonstration.
    • Voluntary consumer payments will be calculated by Northern Gas Networks. These compensation payments will be issued to the Shipper by Xoserve for passing onto the consumer.
    • All MPRNs are monitored to review performance and manage any unforeseen issues that may arise.

    There are no impacts to the switching process. Consumers are able to switch Suppliers in the normal manner.

    Shippers and Suppliers must understand the process changes and their obligations involved for the affected Meter Point Reference Numbers (MPRNs).

    Both Xoserve and Northern Gas Networks are monitoring all activities relating to the MPRNs involved in the demonstration. When notice is received of a change of Shipper or Supplier through the existing industry processes, the new Shipper and/or Supplier will be contacted to talk them through how having a HyDeploy demonstration Meter Point will affect them and what they will need to do differently.

    The use of the hydrogen blend will result in a lower Calorific Value (CV) being passed through the consumer’s meter compared to natural gas; the exact calorific value being received by the isolated demonstration area will be monitored for the duration.

    More gas will need to pass through the customer’s meter than usual, which may inflate Annual Quantities (AQs).

    To ensure the AQs are not impacted, an AQ Backstop date will be applied to the MPRNs, effective from 1 September 2021. The AQ Backstop date prevents any changes in the AQ, even when meter readings are submitted, a revised AQ will not be re-calculated during the demonstration.

    Transportation charges will not be impacted as the rate applied will be the Formula Year AQ set as at 1 April 2021 (or the FYAQ set as a result of an AQ Correction request accepted between 1 December and 19 August 2021).

    During the HyDeploy demonstration, increased gas consumption may be registered through affected meters. Northern Gas Networks and Cadent have agreed with Ofgem to provide voluntary consumer payments, to offset the increase in consumers' bills during the demonstration.

    There should be no change to the charges applied by Shippers to Suppliers and Suppliers to consumers. The consumer credit payment will offset any increase in consumers' bills during the demonstration.

    Northern Gas Networks will submit HyDeploy offset payment information to Xoserve in advance, monthly. Xoserve will then invoice the offset payments to those Shippers with HyDeploy Meter Point Reference Numbers (MPRNs).

    A methodology approved by Ofgem is used to calculate the adjustments for each MPRN, this has been agreed with Ofgem.

    • A factor is used to calculate the adjustment based on the AQ for each meter point.
    • The adjustment also uses a seasonal factor (the same used for Demand Estimation Methodology) to ensure any seasonal impacts in the weather are accounted for. The credit payments will therefore reflect the changes in the seasons; winter are likely to be higher credits than in summer (when more gas is consumed).

    The credit compensation payment issued on 10 August will be for the period of August (4–31 August). Future payments will be issued at the beginning of each month during the demonstration and will be for that calendar month.

    Where there is a Supplier or Shipper changes mid-month, the credit payment will be issued to the Shipper registered of the MPRN on the first of the month. The Shipper must submit to the Supplier to pass to the consumer.

    It is the Shipper’s responsibility to transfer the HyDeploy offset payments to the relevant Supplier. The Supplier must then credit the relevant customer with the HyDeploy offset payment.

    The compensation payments are in line with Schedule 45 - Transmission of Transporter Distributed Payments to Consumers which states that “Where a Supplier receives a payment from a Gas Transporter which is intended for onward transmission to a Consumer, the Supplier shall, within 10 Working Days of receipt, pay or set-off an equal sum”.

    The compensation payments are exempt of VAT.

    A change in UK Link has been applied to set an indicator against those specific MPRNs that have been approved as part of a HyDeploy demonstration.

    The new information held in the UK Link system will be extracted into SAP Business Warehouse (BW) to allow this data to be visible in the Data Enquiry Service (DES); a system that can be accessed via the Xoserve Portal.

    For each MPRN within a demonstration, the following new data items will be
    viewable in Data Enquiry Service (DES):

    • Network Indicator: HYDEP2NGN
    • Network Project start date 13 August 2021 (although actual start date was 4 August 2021)
    • Network Project end date 4 June 2022

    A new package is available to Data Discovery Platform (DDP) users, to help them manage the MPRNs which are part of the HyDeploy demonstration area:

    Network Management Information (MI) – HyDeploy Data Package

    This dashboard focuses on MPRNs within a portfolio which are part of the HyDeploy demonstration. It will specifically focus on portfolio data such as Annual Quantity (AQ), Supplier, Shipper and other Supply Point details. The focus of the dashboards is changes within the portfolio, i.e. when a Supplier or Shipper change takes place, Networks will receive a notification when changes occur.

    Through our DDP and our new dashboards, Shippers and Networks can drill down on data at Meter Point Reference Number (MPRN) level, to obtain more insights. Networks will also be able to export and download data if required.

    The process will remain the same. Northern Gas Networks will ensure that the additional health and safety checks that are needed, will be carried out on site.

    The HyDeploy change was implemented as part of the November 2020 Release, details as follows:
