Futureproof your power

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.

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.

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.

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.

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.

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 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.

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.

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.
