Do you need to futureproof your power?
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. Funding is available through the Accelerated Loss of Mains Change Programme (ALoMCP) to support generator owners/operators and contribute to the cost of making mandatory changes.
Please check our list of Western Power Approved Contractors who have carried out previous works within the programme and may be able to offer guidance and support with updating your equipment.
Introduction to ALoMCP
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.
There is step-by-step guidance available to help you understand what you need to do next – go to www.futureproofyourpower.co.uk.
Applications can be submitted using the ALoMCP Portal. Submissions are received and processed within quarterly application windows. Generators are encouraged to apply as soon as possible using the portal ahead of the final application deadline of 10 May 2022.

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.
If you do not plan to apply for funding or have generating equipment that is already compliant, please complete the Compliance Outside of the Programme Form and notify us by contacting our dedicated team or using the ALoMCP 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 the site’s compliance to your DNO before the deadline.
