Energy managers across the UK are entering a new phase of building decarbonisation. Electrification of heating and cooling, rising deployment of heat networks, and the rapid growth of EV charging infrastructure are reshaping electricity demand across commercial estates. While these technologies are essential to achieving net zero, they are also concentrating load onto the electricity network, increasing exposure to peak pricing and system constraints.
The challenge is no longer simply how to reduce consumption, but how to manage electrified assets dynamically, in real time, without compromising operational performance or occupant comfort.
HVAC systems remain the largest single driver of electricity demand in many commercial buildings. As gas boilers are phased out and electric systems such as VRF, heat pumps and electric resistance heating become more prevalent, buildings are becoming increasingly sensitive to electricity price volatility. At the same time, EV charging introduces new, often unpredictable demand profiles that further amplify peak loads.
This shift means that energy efficiency alone is no longer sufficient. Without intelligent coordination, electrification can reduce carbon emissions while simultaneously increasing operational costs.
Demand-side flexibility is emerging as a practical solution to this challenge. By automatically adjusting electricity consumption for short periods during times of grid stress, buildings can reduce peak demand without affecting comfort or performance. This allows organisations to capture savings while also supporting grid stability and renewable integration.
A recent example of this approach in practice can be seen at Bolton Wanderers Football Club. The club operates a complex estate combining the 28,000-seat Toughsheet Community Stadium and the adjacent Bolton Stadium Hotel, both of which rely heavily on electric heating and cooling to maintain comfort for fans, guests and staff throughout the year.
Like many large venues, Bolton Wanderers faced the dual pressure of rising energy costs and the need to reduce carbon emissions, without disrupting operations or undertaking costly retrofit projects. Through a partnership with Voltalis, the club deployed the Voltalis Edge platform to connect and optimise more than 70 VRF systems and over 160 live monitoring and control points across both buildings.
The system provides real-time visibility of temperatures, setpoints and energy consumption while enabling automated optimisation of HVAC assets. By intelligently reducing non-critical demand during peak periods, the solution is expected to deliver up to 15% electricity savings on heating and cooling, while maintaining guest and fan comfort and enabling participation in national flexibility markets.
Importantly, the deployment required no capital investment from the club and was completed without disruption to stadium or hotel operations. For Bolton Wanderers, this has provided a route to cut operational costs, reduce Scope 2 emissions and modernise building controls simultaneously.
The lessons extend beyond stadiums. Hotels, universities, offices and healthcare facilities all operate similar electric HVAC systems and face comparable pressures around energy costs, carbon reporting and grid constraints. In many cases, buildings already contain the assets required to deliver meaningful reductions in consumption but lack the control layer needed to coordinate them effectively.
As renewable generation continues to expand, the ability for buildings to respond dynamically to grid conditions is becoming increasingly valuable. Flexible buildings can shift or reduce consumption when supply is constrained and make greater use of renewable electricity when it is abundant. This capability will play a critical role in maintaining grid stability as electrification accelerates.
For energy managers, the implication is clear. Investments in HVAC upgrades, heat networks and EV charging infrastructure must be paired with intelligent control and flexibility. Without it, the benefits of decarbonisation risk being offset by higher electricity costs and increased operational complexity.
The next phase of energy management will not be defined solely by new hardware, but by how effectively existing assets are orchestrated. By combining real-time monitoring, automated optimisation and participation in flexibility markets, organisations can reduce consumption, control costs and strengthen resilience – all while supporting the wider energy transition.
