  • Accelerated Loss of Mains Change Programme (ALoMCP)

  • ALoMCP – Coronavirus Pandemic Response – Update 17 June 2020

    According to Government and industry guidance concerning the coronavirus pandemic the Accelerated Loss of Mains Change Programme (ALoMCP) is considered necessary for the short to medium term security of supply and ensuring network resilience. Therefore, programme delivery continues, with the following additional guidance:

    • Applications approved in Windows 1 & 2 that had a Latest Valid LoM Change Date before or within September 2020, but had yet to complete the required works, have had their deadline extended by three months. A further extension to 4th August has been granted to any application that had an initial deadline of 24th March. 

    • DNO/IDNO requirements to witness certain works and complete Sample Site Visits are unchanged. Where DNO/IDNOs are unable to attend sites in person they have agreed to support trials to complete witness testing and Sample Site Visits virtually, for example by means of video calling. Contractors should engage with the relevant DNO/IDNO for details of how to do this.  

    • Payments due to applicants who have already completed their work, and had a Sample Site Visit conducted where applicable, will be processed as soon as is practicable under current working arrangements.  

    • The Programme portal remains open for applications. We ask that the lead time provided in new applications accommodates any estimated delay due to Covid-19 conditions.

    During these extraordinary COVID-19 conditions we understand that you may be unwilling or unable to progress your ALoMCP works within the allotted timeframe. It is our intention that the 3-month extension given should mean that no applicant is penalised if they are unable to work within the Government guidance or decides that the risk to them of undertaking works is too great.

    The ALoMCP will keep the situation under review and update this response as the situation changes and as more information becomes available.


    Further information

    The purpose of the ALoMCP is to improve resilience of the national electricity network in order to maintain security of supply across the country. In an open letter to Network Operators, Ofgem has categorised what activities are to be considered High Priority and Lower Priority Works and Services to enable Network Companies to prioritise works. As the protection modifications proposed under the ALoMCP can be considered “Planned Works necessary for the short to medium term security of supply and ensuring network resilience” they can be considered High Priority. Therefore, further to the recent decision to suspend delivery of the programme, and after careful consideration of the current government guidance, the ALoMCP workgroup recognises that it is possible to continue with the programme whilst remaining compliant with these guidelines.


    1. Where reference is made to government guidance we take this to be the guidance published here.

    Recognised Contractors

    Recognised contractor status will allow “self-certification” (supported by evidence) works to be undertaken in the SSEN network areas as part of the ALoMCP, without the requirement of witness testing attendance by an SSEN engineer for sites where the existing protection device is to be replaced by a new device or loss of mains protection function, or an existing protection device is to be disabled.

    Note: Loss of Mains settings change works will be covered under “self-certification” supported by evidence.

    Achieving Recognised Contractor status

    To become a Recognised Contractor an individual must complete three successful relay replacement-commissioning tests, witnessed by an SSEN engineer and completed to a satisfactory competence level in terms of skill, processes and procedures. If an individual believes they have already met this requirement they may provide evidence of this, i.e. dates of 3 previous commission tests witnessed by an SSEN engineer, giving the name of the site and SSEN engineer who was present, for SSEN to consider. SSEN reserves the right to require further witnessing of testing.

    Recognised contractor status will be granted to individual engineers only, not to a company or other entity. Where a company has several engineers, they will each be required to gain individual approval via the above means.

    Once recognised contractor status is achieved, e-mail notification will be sent from SSEN to the contractor.

    Where works are carried out under the self-certification process, a sample site visit by SSEN may be required following receipt of evidence of completed works.

    If you wish to be considered for Recognised Contractor Status please inform the SSEN engineer present at a Commissioning Test. They will begin a record of visits and confirm when the criteria for recognised status has been met. If you believe you have already met this criteria please email details of your evidence to G59ProtectionSettings@sse.com.

     

    What is Loss of Mains

    Scottish and Southern Electricity Networks is working with National Grid ESO, the other Distribution Network Operators and Independent Distribution Network Operators, to make sure all generators connected to our network are aware of new requirements and are able to apply for funding to make the necessary changes before the requirement come into force. This is called the Accelerated Loss of Mains Change Programme (ALoMCP) and our aim is to help generators understand the changes they must make to their equipment, to ensure safe balancing of the grid and security of supplies. 

    By taking action, generators will be reducing the risk of their generation tripping out unnecessarily. That will contribute to making this country’s secure, reliable power supply even more resilient. 

    Generators are able to apply for funding if the following all apply to their installation: 

    • Assets were installed before 1 February 2018
    • Loss of Mains Protection was provided by RoCoF or Vector Shift
    • The generation operates in parallel with the mains

    What support is there?

    There is funding available to support making these changes. But if the installation qualifies under the points above and the generator does not make the changes by September 2022, they will be considered non-compliant with the Distribution Code and may face enforcement action. Details of the funding available can be found in the Payment Process Specification.

    What do I do now?
