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.
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, available in the useful documents section below, which will provide additional detail on the process relevant to your application.
ALoMCP - Coronavirus Pandemic Response
COVID-19, the Coronavirus pandemic, and the measures taken by government and industry may impact the Accelerated Loss of Mains Change Programme. We’re working with our partners, National Grid ESO, Distribution Network Operators, and Independent Distribution Network Operators, to ensure no one loses their opportunity to receive funding for works completed.
In view of the on-going situation all latest valid LOM change dates issued in Window 1 and Window 2 will all be extended by three months.
Applications should take into account the current uncertainties and propose dates appropriately. Owners and contractors with multiple sites where delays in Window 1 and Window 2 sites will have a knock-on effect should take this into consideration when stating the lead times for completion.
If you have any concerns please email us at G59protectionsettings@Northernpowergrid.com.
ALoMCP Recognised Contractor Status
We've recently produced a set of requirements relating to our 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 or deactivation of the loss of mains protection function within a relay is to be undertaken under the ALoMCP.
