30 Second Briefing
Finning Power Rental has added its first Cat XES120 battery energy storage system to its hire fleet, offering 72 kW output and 127.9 kWh storage that can run stand-alone or in hybrid mode with Cat EU Stage V diesel generator sets to cut fuel use, noise and servicing. Four new Cat Stage V gensets from 20–550 kVA (XQP20, XQP200, XQP310, XQP550 using C2.2, C7.1, C9.3 and C18 engines) broaden options for temporary and construction power. Remote monitoring plus new training in battery safety and hybrid operation aim to support more complex site power configurations.
Technical Brief
- Remote monitoring on the Cat XES120 allows engineers to alter runtime schedules and voltage setpoints off-site.
- Alarm management is centralised, enabling early intervention on overheating, overcurrent or isolation faults without site presence.
- Hybrid configurations are supported by Cat XES120 control logic, coordinating charge–discharge cycles with generator loading.
- Hybrid power operation training is backed by new tooling and certification, formalising competence for complex temporary power schemes.
Our Take
Finning’s move into the Cat XES120 battery energy storage system in the UK sits alongside Caterpillar’s wider decarbonisation push, which in our coverage also includes battery electric rail (Fortescue/Progress Rail) and ultra-class truck fleet renewals, signalling that dealers are expected to offer integrated low-emission packages rather than just engines or machines.
With the XES120 sized at 72 kW/127.9 kWh and paired to Stage V generator sets from 20–550 kVA, Finning Power Rental can target hybrid set-ups for temporary worksites where noise and emissions limits are tightening, particularly in UK urban construction and infrastructure compounds.
Among the 738 Infrastructure stories and 1061 tag-matched pieces in our database, Caterpillar-linked items increasingly combine hardware (generators, trucks, locomotives) with software and control (e.g. the RPMGlobal acquisition), so Finning’s battery rental offer is likely to be pulled into more data-driven, optimised site power packages over time.
