Funding is now available to upgrade your equipment to help deliver a zero-carbon electricity grid through the Accelerated Loss of Mains Change Programme (ALoMCP). If you’re an owner of a generator, apply for funding and be part of the move to a net zero future.
Don’t delay your transition. If you act quickly to make your generation setup compliant, your Distribution Network Operator (DNO) could contribute to your costs and support you through the process.
Check if you need to upgrade
Contact your DNO or a contractor to confirm what action is needed for your generator or request our step-by-step guide.
Submit your application
Our ALoMCP portal is set up and will support you from initial application to upgrade completion.
You will receive funding on satisfactory completion of works.
"The application process is straightforward. It’s an absolute no-brainer."
"There’s no reason to wait."
"I encourage (qualifying) generation owners to take advantage while they can!!"
The transition is mandatory for all non-domestic generation sites and everyone is required to comply before September 2022.
By applying early, you can take advantage of financial support to carry out the work. Late applications may not receive funding.
You will be supporting your community and the wider initiatives that are helping us to meet the UK’s zero-carbon targets.
Your upgrades will make your equipment more efficient and improve the resilience of the grid too.
Value of approved applications
Sites have completed works
The ALoMCP is led by National Grid ESO, the Energy Networks Association, Distribution Network Operators (DNOs) and Independent Distribution Network Operators (IDNOs). Together we are working to build grid resilience and drive the mission to zero-carbon.
Am I eligible for funding?
You may be eligible for funding to upgrade your set up if you have a non-domestic distributed generator that was connected before 1 February 2018 or before 1 July 2018, for inverter based generation.
What do I do if my equipment is already compliant?
If your equipment is already compliant, please let us know by submitting a declaration on the ALoMCP portal. It’s important you do this so we know you’ve checked your set up and to avoid us contacting you unnecessarily.
How do I know if I need to make changes to my equipment?
Use our self-serve tool to check if you need to upgrade your equipment. The tool will also provide clear next steps if you do need to make any changes and helps you to start your funding request.
How can I identify if my inverter or relay is already compliant?
You can quickly check if your equipment is compliant using our knowledge base. This provides an alphabetical list of manufacturers with guidance on whether their equipment is compliant or not.
Is there a funding cap?
You can potentially claim thousands through quarterly application windows. Generator owners of at least 500kW that have Rate of Change of Frequency (RoCoF) settings up to and including 0.2 Hz/second could claim an extra £5,000 by applying to the fast track process until 28 May 2021 on the registration portal.
When does the funding end?
Grants are available through quarterly application windows. Generators are encouraged to apply as soon as they can on the registration portal ahead of the final application deadline of 10 May 2022. The amount of funding available for each site’s changes will reduce for those sites completing the updates after 24 March 2022.
Do I need to change my domestic generator?
This programme does not apply to domestic and similar generation that has been connected under EREC G83. It only applies to generation connected before 1 February 2018 or 1 July 2018 for inverters in accordance with EREC G59.
If I have already made changes, do I need to make more?
If you have not applied for funding you can still do so. If you can show that the changes meet the new requirements you will be paid for the changes. And if you find that your equipment is already compliant you must still inform your DNO to ensure that your assets are registered correctly. This scheme supports electricity generation owners in achieving compliance to the Distribution Code requirements in EREC G59.
What are the setting changes required in the updated EREC G59?
All generators that are connected to the distribution networks in Great Britain have Loss of Mains protection, one of the many protection requirements on the electricity system.
This applies to generating plants that run in long-term parallel with the distribution network and are within the scope of EREC G59, regardless of the type of generator, such as PV, wind or gas. Loss of Mains is designed to check if a generator is still connected to the supply network. Updated EREC G59 requirements must be implemented by generation owners by 1 September 2022.
Where LoM is provided by vector shift, it must be removed and/or replaced with Rate of Change of Frequency Protection (RoCoF). RoCoF is the rate at which frequency changes and is used to detect the absence of the connection to the system and disconnects the site if that RoCoF exceeds a specific value. The RoCoF setting requirement has been changed to 1 Hz/s with a definite time delay of 500 milliseconds. It will mean National Grid ESO will be able to operate the grid more efficiently.
Most of the costs incurred in managing the LoM risk on the electricity transmission system are to limit the RoCoF to below 0.125Hz/s. Currently NGESO is limiting the RoCoF to below 0.125Hz/s so that generators with RoCoF protection are not inadvertently tripped. The costs are significant and are paid for by all of us through our electricity bills. These costs could be reduced if RoCoF above 0.125Hz/s was allowed. To achieve this, we need to change the RoCoF settings at all sites where RoCoF protection has an existing setting of 0.5Hz/s or less.
Do I need to use a contractor?
No – there is no compulsion to use a contractor, recognised or not. A recognised contractor is one who is “recognised” by the DNO for having appropriate experience and skills to undertake the work of the programme without direct scrutiny by the DNO. This enables a Recognised Contractor to plan site works independent of the need to arrange a suitable time/date for the DNO to witness the works.
