IN Brief:
- Electrification works have been completed at Gillmoss bus depot in North Liverpool.
- The depot can charge more than 100 publicly owned battery-electric buses for the Liverpool City Region.
- The project includes upgraded grid connections, high-powered intelligent charging bays, and engineering workforce upskilling.
Liverpool City Region Combined Authority has completed multimillion-pound electrification works at Gillmoss bus depot, enabling more than 100 publicly owned battery-electric buses to enter service across the region.
The North Liverpool depot has been upgraded with new grid connections and high-powered intelligent charging bays that can fully charge a double-decker bus in as little as 90 minutes. The project has been delivered by the Combined Authority with Scottish Power Energy Networks, VEV, Stagecoach, and Liverpool City Council.
Gillmoss Depot, operated by Stagecoach, serves bus routes across Liverpool and Knowsley. It will now act as the primary charging and operational hub for the region’s expanding zero-emission bus fleet.
The fleet consists of 108 battery-electric buses built in the UK by Alexander Dennis and Wrightbus. The vehicles began arriving earlier in 2026 and can travel up to 275 miles on a single charge. Initial operation will support driver training and testing before the fleet moves into franchised services.
The depot programme also includes investment in engineering and maintenance functions, with local engineers being upskilled for electric vehicle maintenance. Charging equipment, high-voltage vehicle systems, battery diagnostics, thermal management, depot energy control, and electrical safety procedures all become part of daily fleet operation once diesel vehicles are replaced by battery-electric buses.
Depot electrification is a different engineering task from installing public charge points. Buses return in defined operating windows, require predictable charging schedules, and must be available for early-morning service. A depot therefore needs a coordinated system combining grid capacity, chargers, charge management software, maintenance bays, parking layouts, fire strategy, staff procedures, and operational resilience.
High-powered charging concentrates demand in locations that were not originally designed around large battery-electric fleets. Site capacity has to account for simultaneous charging, future fleet expansion, seasonal variation, spare capacity, and operational disruption. Intelligent charging can sequence charging sessions and reduce peaks, but it still depends on a robust grid connection and carefully designed electrical distribution.
Heavy transport electrification is moving from demonstration into full infrastructure delivery. Scania’s bidirectional megawatt truck charging demonstration showed how high-power vehicle charging is beginning to merge with flexibility and grid-support functions. Bus depots are moving along a similar path, with charging systems expected to manage power as well as deliver energy.
Funding for the Liverpool zero-emission fleet and depot upgrades was secured through the City Region Sustainable Transport Settlement and the Department for Transport’s Zero-Emission Bus Regional Areas 2 fund. The rollout is tied to wider bus franchising plans, with St Helens and Wirral leading the transition in September 2026 before Knowsley, Liverpool, and Sefton move fully into franchised operation by the end of 2027.
The electrical infrastructure is being delivered ahead of the full operational change. That sequencing reduces the risk of buses arriving before sufficient charging capacity, grid connection works, maintenance training, and operating procedures are ready.
As more authorities move toward zero-emission fleets, depot electrification will remain a substantial workload for distribution networks, contractors, fleet operators, and charging specialists. The technical challenge has moved beyond the range of individual vehicles. Whole depots must now supply reliable, repeatable, high-power charging across fleet schedules without compromising service availability.
