Accelerated Loss Of Mains Change Programme
We, alongside other Distribution Network Operators (DNOs) and Independent Distribution Network Operators (IDNOs), are joining forces with National Grid ESO on their 'Accelerated Loss of Mains (LoM) Change Programme'. The initiative helps owners of generation assets make the necessary changes to ensure compliance with new settings introduced under the Distribution Code.
The new requirements specify that the current protection settings required for any new generation connecting to the network must now also be applied retrospectively to existing generation with loss of mains protection.
Loss of mains protection is used to prevent damage when issues occur on the electricity distribution network leading to the disconnection of generation unnecessarily. The effect of this, more often than not, happens when more renewable generation is running and the costs of manage any disruptions are paid for by the consumer and electricity industry. Updating loss of mains protection will therefore deliver a step change in how the electricity system can be operated allowing more low carbon power at a lower cost.
All owners of generation installed prior to February 2018, that currently comply with EREC G59, now need to comply with new settings required for the interface protection. This means owners will need to make changes to their protection settings, and have until 1 September 2022 to do so.
We recognise that generators may incur some costs as a result of having to make these necessary changes, and the industry has arranged for support and funding to be available to help. To qualify for funding support, generators need to register their assets through the ENA's dedicated portal, this can be found on the ENA's website.
The funding is limited and will be awarded based on a set of criteria which will be published on the Energy Network Association’s website. One of the criteria relates to how soon generators can make the changes, so there is a benefit in applying early. There is also a 'Fast Track Incentive Scheme' available with an additional payment made to applicants who meets specific pre-qualifying criteria. Further details of this are available on the ENA ALoMCP Registration Portal.
We have produced a flowchart detailing the process that your application will go through as eligibility for ALoMCP funding is assessed. It also contains guidance relating to what steps should be undertaken to ensure your generation site is G59/3-7 compliant.
Northern Powergrid ALoMCP FAQs
We have produced FAQs, which will provide additional detail on the process relevant to your application.
ALoMCP Recognised Contractor Status
We've made available the contact details of a number of individuals who hold Northern Powergrid ALoMCP Recognised Contractor status, they may be able to assist you to undertake the works required to achieve EREC G59/3-7 compliance.
We have produced a set of requirements for ALoMCP Recognised Contractor accreditation. Achieving ALoMCP Recognised Contractor status would negate the requirement for our teams to carry out witness testing at sites where relay replacement work is carried out under the ALoMCP.
For further details please email G59protectionsettings@Northernpowergrid.com.
We have recently written to Stakeholders to inform them about the Accelerated Loss of Mains Change Programme and have received some requests to confirm the legitimacy of the communication. You can download a copy of the letter to confirm its authenticity by clicking here.
Case study - Colin Lockwood - WindCare
Northern Powergrid Recognised Contractor WindCare have successfully completed over 200 ALoMCP upgrades at different sites coming across lots of different sites, setups and relay types – all of which need their own tailored set of works. They have worked with multiple DNOs to apply for funding to make the required change, at no cost to the owners.
Case study - Martin Bleasby - EnergyForce
Northern Powergrid Recognised Contractor EnergyForce have completed many ALoMCP applications on behalf of generators. They run the whole process from start to finish so that for many generators, it’s as easy as a phone call on their side. They have processed applications from large scale solar installations to small manufacturing installations and combined heat & power (CHP).
