Keep your electricity generator up to date

** The last date to submit funding applications through the Accelerated Loss of Mains Change Programme (ALoMCP) was the 10 May 2022 and funding is no longer available. **

If you own an electricity generator, you may need to comply with mandatory changes and update your equipment. Non-compliant sites may be subject to an enforcement process, so it is important that you check your generating equipment and ensure compliance by 1st September 2022. 

Please check our list of Recognised Contractors who have carried out previous works within the programme and may be able to offer guidance and support with updating your equipment.

 Loss of Mains Protection

                 

Loss of mains protection is used to stop any damage when problems occur on the electricity distribution network. Methods used in the past can disconnect generation when it is not necessary to do so. The effect of this, more often than not, happens when more renewable generation is running and the costs of trying to stop any disruptions are paid for by the consumer and electricity industry. Changing loss of mains protection will therefore deliver a step change in how the electricity system can be operated and will allow more low carbon power to flow at lower cost. 

  Compliance Declarations

Owners of generating sites in Great Britain are required to ensure that their installations are compliant with Engineering Recommendation G59/3-7. Once your equipment is compliant, please complete the Compliance Outside of the Programme Form and notify us by contacting our dedicated team or using the ENA Portal  in order to declare your site’s compliance. We will update our records and notify National Grid ESO.

Even if you have already taken action, you will still need to declare that your site is compliant to your relevant Distribution Network Operator before the compliance deadline of 31st August 2022.

Applications in Progress

If you submitted an application prior to the 10 May 2022 deadline, you have until the 31 August 2022 to submit the proforma and evidence to alomcp@westernpower.co.uk. More information can be found in the ALoMCP Technical FAQs.



Tapering

Funding amounts are subject to tapering depending on the date the works were completed as follows:

**Sites completing the changes after 24 March 2022 but on or before 23 June 2022 will be paid 80% of the payment values in the Table of payments stated in the ALoMCP Overview document.  This table can be found within the ALoMCP Payment Process Specification document**

**Sites completing the changes after 23 June 2022 but on or before 31 August 2022 will be paid 70% of the payment values in the Table of payments stated in the ALoMCP Overview document.  This table can be found within the ALoMCP Payment Process Specification document**

Further information

  • The Accelerated Loss of Mains Change Programme (ALoMCP) is an industry-led funding programme to help generators achieve mandatory compliance as per changes to Engineering Recommendation G59/3 and the industry Distribution Code.

    The ALoMCP gives distributed generation owner/operators the opportunity to receive funding towards making these mandatory changes to the existing Loss of Mains protection settings at their site.

  • These changes will provide increased system stability and resilience across the GB electricity network. By making these changes National Grid ESO will be able to operate the electricity network more efficiently, reduce balancing costs and therefore provide savings to electricity customers on the network.

  • Loss of mains protection (LoM) exists at distributed generation sites to prevent generators supporting an islanded section of the electricity distribution system, which could pose a hazard to the system or customers connected to it.

    Methods used in the past can disconnect generation when it is not necessary to do so. The effect of this more often than not happens when more renewable generation is running, and the costs of trying to stop any disruptions are paid for by the consumer and electricity industry.

    Changing loss of mains protection will therefore deliver a step change in how the electricity system can be operated and will allow more low carbon power to flow at lower cost. The changes to the protection settings will provide increased system stability and a reduction in nuisance tripping of generation during system disturbances.

    In most cases, the LoM protection is provided by a protection relay on site. Some sites may have LoM protection built within the generation plant e.g. within inverters. You will need to contact a qualified contractor in order to determine what changes are required at your site.

  • The distribution network operators (DNOs) and National Grid ESO (NG) have proposed a scheme where contractors are incentivised to identify and declare compliance for appropriate sites which haven’t yet participated in the ALoMCP (either by an existing compliance declaration or an application for funding).  Western Power Distribution (WPD) has emailed contractors who have engaged with WPD on ALoMCP inviting them to participate in the Contractor Incentive Scheme (CIS).  Further information about the CIS can be found in the FAQs.

    If you are a contractor that has engaged with WPD on ALoMCP and would like further information, please email us at alomcp@westernpower.co.uk.
