Energy and Construction
Founded in 2003 in Montebello Vicentino, Veneto, Italy, Energy Gruppi Elettrogeni brings over 20 years of specialist experience to the construction sector across four dedicated product lines: the Rental range for mobile construction and hire use, the Industrial range for permanent or large-scale installations, the Active professional range for smaller sites and trade use, and the Midnight Light Tower range for site illumination. Every unit is manufactured entirely at the Vicenza factory with no outsourced production, backed by ISO 9001:2015 quality certification maintained since 2015.
The flagship Rental range was engineered specifically for construction and plant hire from the outset — incorporating certified lifting hooks, anti-tip forklift pockets, anti-shock rubber mountings, heavy-duty 3 mm steel base frames, sound-attenuated enclosures with inspection-access side doors, battery isolation switches, and ComAp AMF25 automatic mains failure control panels as standard. Available with Perkins, Yanmar, and Kohler engines with Stage V emission compliance across the majority of models, these generators are built to sustain intensive daily use in demanding outdoor environments.
- Rental Range — Purpose-Built for Sites - 9 to 330 kVA across six size bands, designed for heavy daily use and repeated relocation
- Stage V Emission Compliance - Available across the majority of the Rental range for use in Low Emission Zones and restricted working areas
- ComAp AMF25 Control - Automatic mains failure start and advanced panel management fitted as standard on all Rental sets
- ISO 9001:2015 Certified - Fully audited quality management across the entire Vicenza manufacturing facility since 2015
Key Features & Benefits
Energy construction generators are engineered for the demands of professional building sites — robust, mobile, safe to operate, and ready to work continuously in harsh outdoor conditions.
Built for Repeated Relocation
Every Rental range unit features anti-tip forklift pockets, a certified central lifting hook, and reinforced tow bars. Moving a generator between areas of a large site, or loading it onto a flatbed for the next project, is a daily reality that the Rental range handles safely every time.
Heavy-Duty Construction
Rental enclosures are fabricated from 3 mm steel plate with class 1 certified soundproofing material and anti-crash door barriers. Anti-shock rubber mountings protect the drivetrain from vibration on rough ground, and the solid base frame provides stability on the uneven terrain typical of active construction sites.
Stage V Engines Available
The majority of the Rental range is available with Stage V compliant engines from Perkins, Yanmar, and Kohler — essential for working in Low Emission Zones, town-centre construction, and sites subject to environmental planning conditions. Stage 0 variants are available for unrestricted areas.
ComAp AMF25 Control Panel
Every Rental generator is fitted with a ComAp AMF25 control unit as standard, providing automatic mains failure start, load management, and fault protection. An eight-outlet distribution kit with individual circuit breakers and differential protection is available, fully configurable on request.
Designed for Easy Maintenance
Side inspection doors provide access to all service points without removing the enclosure. Coolant filler, battery isolation, and oil drain fittings are all positioned for fast site access, minimising downtime during routine servicing between hire periods or during extended project deployment.
Midnight Light Tower Range
The Midnight range of LED light towers completes the construction package — available engine-driven, motorless (mains-powered), or with integral generator. Road-type approved Yanmar Stage V models with hydraulic masts up to 9.5 m provide full night-time site illumination as a single-supplier solution alongside the generators.

Why Choose Energy for Construction
The Rental Range Was Built for Sites
Unlike generic industrial generators adapted for hire, the Energy Rental range was engineered from the outset for daily construction use — forklift pockets, certified lift hooks, anti-tip protection, anti-shock mountings, and inspection-access doors are standard features, not costly extras.
Stage V Compliance Across the Range
With growing numbers of Low Emission Zones and planning conditions restricting construction emissions across the UK, Stage V engine availability from 9 kVA up to 330 kVA ensures contractors can work on restricted sites without carrying a separate compliant fleet.
Six Power Bands — One Supplier
From a 9 kVA compact set for a domestic project through to a 330 kVA set for major civil infrastructure, the Rental range covers six power bands with consistent design standards, interchangeable service procedures, and the same Italian manufacturing quality throughout.
ComAp AMF25 — Industry-Standard Control
The ComAp AMF25 automatic mains failure control unit is fitted as standard across the Rental range, providing the automatic start, load management, and fault logging that site managers and electrical contractors expect as baseline requirements.
Lighting and Power from One Supplier
The Midnight LED light tower range — engine-driven, motorless, or with integral generator — allows contractors and hire companies to source both power generation and site lighting from a single Energy product family, simplifying fleet management and parts support.
