The contractor is rolling out UK-made Revolution Battery units from Dumarey Green Power across it sites, following a successful trial that saw costs and emissions slashed by over 90%.
The first wave of installations are in London at Canada Street Phase 2 and 55 West Ealing sites, alongside an already live unit at Trocoll House in Barking.
Further deployments are planned across upcoming jobs in the Midlands and North of England.
During trials, a single battery system powered two Moritsch RTL 195 luffing cranes from a 32A 3-phase mains supply – replacing two 200kVA diesel generators running up to 60 hours per week.
Trial savings
-
Weekly fuel bills slashed from £1,400 to £80 per crane
-
Emissions down from 3,000kg to under 200kg CO₂ per week
-
Smaller, quieter and more reliable than diesel units
HG chief executive Adam Quinn said: “The performance of the Revolution Battery during the trials was exceptional – reducing carbon emissions and running costs by over 90%. These results speak for themselves.”
He added the investment supports HG’s wider net-zero targets and commitment to buying from local suppliers wherever possible.
The Revolution Battery works differently to traditional BESS systems by decoupling energy storage from output power. That means fewer battery cells are needed, reducing weight, size, and embedded carbon. If mains power is not available, a 40kVA generator can charge the unit in under three hours daily.
