Why is the UK energy flexibility market is ready for Voltalis

UK energy flexibility market technology

The UK energy flexibility market is entering a critical moment this winter – mornings are brisker, evenings are cold, and the warm winter woollies are out.

As we prepare for another chilly UK winter, the energy conversation becomes more urgent: how will we keep homes warm and the power grid stable?

The grid is a balancing act

For the grid to function smoothly, it must balance energy supply and demand at all times. When demand outpaces supply – often due to cold snaps or low renewable output – gas plants are used as a backup. While effective, this approach is neither sustainable nor affordable.

Renewable energy is cheap once installed, but fossil fuels like gas are expensive and polluting. In the UK, household electricity prices are based on the wholesale price, which changes every 30 minutes based on the most expensive energy source. Often, this is gas.

This means households pay more when gas is used to stabilise the grid. These spikes are now more frequent due to global gas supply issues and the fire-damaged Sellindge interconnector – making energy price volatility a national concern.

The UK energy flexibility market needs a better solution

Already well established in France with over 200 000 homes and businesses connected to the Voltalis network, we have a proven record in managing demand on the grid. 

With the UK in the grips of an energy crisis and the onset of winter, set to exacerbate the situation, demand response is the solution. And companies, like Voltalis, entering the UK energy flexibility market must be agile and proven.

In addition to the above, there are additional reasons why the UK power market has become increasingly open to Voltalis.   

Let’s unpack these reasons a little.

  • The UK is in need of greater grid flexibility 
    There is a push to integrate more renewable energy resources into the grid. Because these are intermittent by nature, the grid needs more flexibility. This is where we step in and step up. We can manage demand-side response to ensure stable grid operation.

  • Regulatory support
    Regulatory support for companies like Voltalis has strengthened, with the UK government and Ofgem (Office of Gas and Electricity Markets) introducing initiatives like the Capacity Market and the Balancing Mechanism. These regulations allow us to compete on a level playing field with traditional energy networks, opening up more opportunities for us to help stabilise the grid.

  • The UK government has an ambitious net-zero emissions target.
    The UK aims to be net-zero by 2050. While that may seem a long way off, it’s just around the corner when you consider the changes that need to happen. Reaching this goal will rely heavily on companies like Voltalis, who play a vital role in balancing energy demand.

While our approach builds on traditional demand response, what we offer goes a bit further. We call it Automatic Demand Response. By using smart technology, we tap into real-time pricing signals to maximise cost savings and deliver a smoother, more user-friendly experience for electricity users. Our system adapts in real-time with high efficiency, responding to grid conditions as they change, optimising resource use to boost grid stability.

Demand Response the Voltalis way

It’s as simple as installing a switch onto your heating and cooling systems. When demand on the grid spikes or energy supply dips, the switch optimises the electricity consumption of your systems for a short period. These minor adjustments are imperceptible and won’t impact your comfort at all.

You may ask, “If they are so small, how do they help ease demand on the grid?” The answer is, there is power in numbers. The more households and businesses that adopt the Voltalis system, the greater the collective energy savings. If, for example, 250,000 premises are each saving a small amount of energy, those savings are substantial enough to make a real impact. 

Another question, or perhaps rather a concern you may have is, “What happens if I am particularly chilly and don’t want the temperature on my heating system optimised today?” Don’t worry—we’ve got you covered. Our MyVoltalis App—a full home energy management system— lets you control, monitor and optimise your electricity consumption remotely. Or, if desired, you can switch the Voltalis functionality off completely. 

An added perk of the Voltalis system is that you, as the end user, don’t pay a cent for the installation or the service, making it not just a fabulous non-intrusive way to help manage demand on the grid but free too. Which, of course, may raise even more questions. Yes, it is absolutely free. No, there is no catch. Why? Because Voltalis is already paid by the electricity networks for its contribution to stability and security of the grid.

Future thinking

This is not just a solution for now, for this winter. It is a long-term solution that addresses many of the UK’s energy challenges. 

Our solution is simple yet highly effective, and we are ready to go right now. And, interestingly enough, while we are able to solve the UK’s broader energy issues, we are also uniquely positioned for the UK market in other ways. For instance, one in six homes in the UK were built in the 19th century. Updating these older homes to make them more energy efficient can be quite a task. But with Voltalis, it’s easy and hassle-free: no renovation required. All that’s needed is the installation of the Voltalis switch. An elegant solution indeed and all together better. 

Whether you’re a home or business owner, whether you’re a landlord or social housing associations, contact us today to learn how Voltalis is ready to scale in the UK energy flexibility market this winter and can help you contribute to the stability of the grid, save money and reduce the UK’s reliance on fossil fuels now and in the future.
