How Power & Grid secures sustainable energy supply
Modern life relies on power. Hospitals, transport hubs, utilities, data centres, government – every sector needs secure grid connections. And as global energy supply becomes more unpredictable, we’re here to power a resilient energy future.
Gain expert high-voltage support
With Mitie Power & Grid, you get specialist high-voltage connections support. This includes Distribution Grid connections up to 132kV and Transmission Grid connections at 275kV and 400kV.
Each of our grid connection business units are NERS (National Electricity Registration Scheme) accredited independent connections providers (ICPs). So you can be assured you’ll get robust, compliant connections, every time.
Implement reliable, efficient connections across your estate
We deliver safe and secure grid connections in the most cost-effective way possible. Our team of specialist engineers is backed by decades of combined experience and will keep your grid and renewable energy infrastructure operating efficiently well into the future.
Build resilience against outages
Proactive maintenance and ongoing compliance for all our Power & Grid projects make it easy to detect emerging issues, avoid disruption and reduce risks. And by implementing renewable energy generation on your site, you can consume your own low-cost, local power to reduce your dependence on the grid and exposure to price volatility.
Accelerate your transition to net zero
Adding renewable generation to your site doesn’t just add security to your supply – it also helps decarbonise your estate. We offer end-to-end green energy solutions in all environments, supported by Custom Solar, a pioneer in UK solar.
With a proven track record in complex solar photovoltaic (PV), battery energy storage solutions (BESS) and electric vehicle (EV) infrastructure projects, we’re perfectly positioned to help you.
Enjoy end-to-end support throughout your project – and beyond
Our team will remain by your side for the entire project lifecycle. From grid connection applications and design to installation and maintenance, you get the specialist support you need to make sure your project’s a success.
Perhaps you’re setting up a new grid connection, installing a new solar array or upgrading existing electrical infrastructure. We’ll meet you wherever you are, and guide you through to project completion and lifecycle asset management.
Find the right funding option for your project
The benefits of renewable energy infrastructure are clear. But that doesn’t always translate to a simple financing process.
We aim to take the complexity out of renewable energy investments with a range of purchase options. You can choose a fully funded Power Purchase Agreement (PPA) with no upfront costs. Or you can fund the project yourself to fully own the asset and benefit from direct energy savings. We can also introduce you to asset financing partners. Whatever financing option you choose, we offer tailored, flexible delivery models aligned to your goals.
