Everything You Need To Know About The ALoMCP Updates In 2022

At Dale Power Solutions, we know that in a world where our reliance on fossil fuels for power generation and electricity simply has to change, the need for businesses to have a thorough Loss of Mains (LoM) protection in place for electricity-producing generators, such as those for wind turbines, is vital.

That’s why the Accelerated Loss-of-Mains Change Programme, frequently referred to as ‘ALoMCP’, can be so beneficial for businesses. The scheme aims to supply operators in the energy network with funding to install new relays and systems so that they meet the recommended G99 rules, or at least comply with the now compulsory G59-3.7.

Here at Dale Power Solutions, we strongly encourage you to act fast and apply for funding as soon as possible because the deadline for applications window 6 ends on 9th February 2021, with no fixed date confirmed for application window 7.

While we’re known as experts in the installation and maintenance of diesel generators and Uninterruptible Power Systems (UPS), we can also help your business benefit from the scheme and ensure everything is in place so you avoid hefty fines. That’s why, in today’s blog, we’re going to be discussing some of the generator protection relays that need to be updated by 2022, which sectors will be affected, and how our products here at Dale Power Solutions can ensure you have the correct relays in place.

The Generator Protection Relays That Need To Be Updated By 2022

A recent update to the Distribution Code has resulted in the need for generators, that supply voltage to equipment and devices, to make vital changes to their generation protection. From updating protection device settings through to reducing disturbances on the electricity network – there are a variety of changes needed to meet the criteria.

Ultimately, these updates are designed to improve the strength of the mains network, and reduce the loss of power generation and widespread power cuts caused by major or minor grid disturbances in the electricity industry.

Importantly, the deadline for this update is 1st September 2022 and the deadline for sending funding applications during Application Window 6 ends on 9th February 2021, with no fixed date confirmed for Application Window 7.

For businesses who require funding to ensure their application is successful and that their sites or places of work comply, they can apply for funding via the aforementioned ALoMCP. This fund, organised by the National Grid, can help people through the process of updating their generator’s relay settings.

The criteria for those September 2022 regulations will affect every form of non-domestic generation that was installed before February 2018, and have a capacity between 10kW and 50MW. Non-domestic, of course, meaning generators that power appliances and systems outside the home, such as telecommunicationsdata centres and transport centres as well as other market sectors.

5 Key Facts About The New Rules For Energy Generators

  1. It affects wind, solar and other small and large scale power generation and distribution systems.
  2. Applications must be made by February 2021.
  3. Northern Powergrid, along with Dale Power Solutions (through relay provision), can help you meet the requirements.
  4. Thousands of pounds worth of funding is available.
  5. There is also an option for equipment to be ‘fast-tracked’ and get an additional £5,000.

What Is The Accelerated Loss Of Mains Change Programme (ALoMCP) And Why Is It Important?

Let’s apply some context to these changes and look at what the ALoMCP is, the process, and why it is important when discussing the world of mains protection.

Back in April 2019, the then-existing G59-3.7 standard was replaced by the G99, and meant that sites where equipment and systems were connected to the network after February 2018, and that used G59-3.7, had to upgrade to G99. Generation owners who are connected to sites before February 2018 don’t need to comply with G99, however, they must meet the conditions laid out in G59-3.7.

This period of upgrades to mains protection, and requirements to meet new compliance for generation sites, is called the ALoMCP and is run by the National Grid ESO (Electricity System Operators) and the Network Operators (DNOs). It is an important programme because with power output increasing year-on-year, the risk to the security of the supply, and the grid itself, increases if there is no compliance. Also, without this accelerated loss of mains change programme in place, it would take decades to convert the tens of thousands of sites which need to change.

As we mentioned in the previous section, funding has been made available to ensure compliance with the G59-3.7, which is now the minimal requirement, and G99. The availability for generation sites to apply for this funding is open from now until February 2021. Though there is expected to be a further round of funding, that may not end up being the case, and therefore, we’d recommend applying as soon as possible. There is also the added caveat that the portal which is used to accept applications was available from mid-May in 2019. Here at Dale Power Solutions, we strongly advise you to fill in your application form before the application window even begins to close to ensure compliance based on the new conditions.


There are two levels of funding available: The first level is the most common and will be required if a simple change in the protection device settings is needed. For this funding category, the business owner will receive £1,500 for the settings change, and an additional £500 for each relay (up to a maximum 5 relays) which is a total funding value of £4,000 per site. If, however, the problem is more complex and the relays require replacing, you can receive up to £4,000 for each relay.

In addition to these two levels of funding, the programme has also introduced, as we touched on earlier, a fast-track scheme which can help fund generators that have a capacity between 500kW and 5MW, with an extra £5,000 for completing the work required to meet G99 and/or G59-3.7 within four weeks of starting the application process.

Is My Site Eligible For Payment?

What follows is some guidance that will help you understand if you are eligible for this scheme. To be eligible sites must:

  • Be running in long-term parallel mode.
  • Connected before February 2018.
  • Have not previously received any LoM payments.
  • Have your LoM protection provided by a vector shift or RoCoF (Rate of Change of Frequency), which have settings that are more sensitive than the ones required by G59-3.7.

Work In These Sectors? You Should Take Action Now

Here at Dale Power Solutions, we work with a range of different industries in both the private and public sector. From medical institutions and utilities and renewables, through to defence and marine oil and gas, we have worked with these industries, and many more, making us perfectly placed to help businesses across a range of sectors with this scheme. If you operate within the following industries, you may very well need to take action to prevent hefty fines once the scheme ends and new regulations come into place in September 2022.


In farming and agriculture, self-reliant energy generation is extremely common, owing mainly to the fact that farms tend to be remote and there is so much land on which to place installations such as solar panels or wind turbines. Further, many farmers and people in agriculture enjoy the added benefits of saving on bills, earning a second stream of income and the moral advantage that they’re supporting a low-carbon future. ALoMCP is vital for people in this industry because it ensures that their power generation, and those benefits, remain lawful and compliant, and that they are working to create a stronger energy network.


Hotels produce an incredible amount of power output every month. Guests use the power available, as do different sections of the hotel from the laundry services team through to the kitchen staff. This huge amount of power is why a lot of hotels install some solar capacity element to help save money on bills, increase generation capacity and look like a hotel that takes environmental sustainability seriously. Acquiring ALoMCP now can give you peace of mind that you have applied during the current window and are compliant past September 2022, leaving you to focus on other aspects of your hotel business.


Schools who use their roof space, or spare land, to create energy generation assets such as solar panels, need to apply for the ALoMCP funding to ensure all this can remain compliant. A lot of schools will use alternative energy generation methods to not only reduce bills and offset emissions, but to also inspire and educate both the pupils and the people in the local area.


Very often a birthplace of ideas and inventions, universities and colleges have, over time, invested in greener energy production as a way of saving money and helping to spark the imagination of those that live and learn there. Very often, these institutions are the home of new technology that will lead to a more sustainable future, so it makes sense for them to have their own ways of generating power. These reasons, then, are exactly why educational establishments such as these need to start applying for this funding now.
