Merseyside Police

Police fleets don’t get to go offline. Response vehicles, patrol cars, and support vehicles need to be charged, ready, and back on shift, with no room for chargers that are unreliable or slow to install. As Merseyside Police transitioned more of its fleet to electric in support of its Net Zero by 2040 target, the force needed on-site charging infrastructure that could keep pace with day-to-day operational demand, not just top up overnight, but genuinely support a working fleet.

At the same time, the force wanted its charging infrastructure to do more than move the emissions problem elsewhere. Charging a growing EV fleet from grid power alone only shifts the carbon cost upstream. Merseyside Police wanted its own renewable generation feeding directly into that charging, so that fleet electrification was a genuine step towards its Scope 1 and 2 emissions target, not just a change of fuel type.

HALO FastHub combines rooftop solar PV, smart energy management, and EV charging in a single integrated unit, installed on-site with no groundworks and no planning permission required. For Merseyside Police, that meant on-site charging that draws on power generated at the site itself, reducing reliance on grid electricity and cutting the carbon cost of every charge, without lengthy installation timelines that would have disrupted operations.

The system’s smart energy management balances solar generation against real-time fleet charging demand, so power generated on-site is used as directly as possible rather than exported and drawn back later at a loss. It’s infrastructure built for a working fleet, not a showcase, engineered to perform reliably at the pace an operational police force needs.

The installation now supports 241 charging sessions a month on average, delivering 28,883 kWh of renewable-supported charging a year, and saving an estimated 12.1 tonnes of CO₂ annually against the equivalent grid-only alternative. That’s measurable progress against a public Net Zero commitment, not just a claim.

For a public sector fleet under real operational demands, that’s the case for solar-supported charging in one line: it works as hard as the fleet does, and it moves the sustainability target forward every time a vehicle plugs in.
