Generator Rental Services

What Generator Rental Services does

Generator Rental Services Limited (GRS), founded in 1997 and headquartered at 40-42 The Concourse, Henderson, Auckland, is a wholly-owned subsidiary of Sweden's Atlas Copco Group and operates New Zealand's largest readily available range of rental generation equipment (10kVA to 2,000kVA, with transformers up to 22,000 volts), temperature-control equipment (chillers 200-750kW, packaged AC units, air handlers, diesel boilers, heat exchangers, electric heaters), and an emerging sustainable-power line (POWRBANK battery storage, 20kVA hybrid systems, Atlas Copco ZBP lithium-ion units, POD20 solar hybrid). The business runs a four-branch direct-rental model (Auckland, Tauranga, Hastings, Christchurch) supported by its own delivery fleet (flat-deck, crane, swing-lift trucks, towable trailers) and 24/7 on-site technicians, with regional account managers covering Auckland, Central North Island, and Lower North Island.

GRS monetises primarily through usage-based equipment rental on daily, standby, or 24-hour billing cadences, supplemented by subscription-style monthly credit-account billing for long-term standby contracts and ancillary service fees (delivery, installation, refuelling via its own 400L to 12,000L diesel-tanker fleet, site management, and a 10% insurance administration fee). It also sells turnkey solutions including semi-trailer-mounted portable substations (800kVA generator + HV switch + step-up transformer + remote control) for grid-support deployments. Disclosure case studies show large-scale capability: 6MVA+ mobilised across multiple network points during coastal storm response, 10MW of temporary generation seamlessly integrated to network for voltage support, 7.5MVA at 11kV supplied to an exploration/harvesting site, and hybrid energy solutions delivering up to 85% generator runtime reduction and 90% emissions reduction.

GRS serves a horizontal mix of customers led by utility/lines companies and grid operators (for SAIDI/SAIFI management and emergency response), industrial and commercial facilities requiring backup power or climate control during planned maintenance and breakdowns, and adjacent verticals including construction, events, agriculture/wineries, food processing, marine and rail, film production, and hospitality. Procurement is predominantly enterprise-field-sales-driven (no-obligation quotes, dedicated regional account managers) supplemented by a self-serve website channel with an online generator-sizing calculator and enquiry forms.

Expansion highlights5 records

Regional players

• Coates Hire: Australia's largest equipment rental company, offering generators, climate control, and access equipment. Comparable horizontal rental model and customer segments, though broader in equipment categories and operating only in Australia.
• Energy Power Systems Australia: Australian Caterpillar dealer providing generator sales, rental, and service. Comparable product mix (diesel generator sets, temperature control) and target customers (utilities, mining, construction, events), but operates across Australia rather than NZ.
• Speedy Hire: UK-listed equipment rental provider offering generators, climate control, and tools across UK and Ireland. Comparable horizontal rental model and customer segments, though geographically focused on UK rather than Australasia.

Broad incumbents

• Aggreko: Global leader in temporary power and temperature control rental with extensive diesel, gas, and battery fleet. Directly comparable business model to GRS; Aggreko's presence in Asia-Pacific makes it the closest large-scale comparable, though it operates at much larger scale across multiple countries.
• Caterpillar Rental Power: Global manufacturer and rental provider of large generator sets (including the Cat XQ series that GRS's 2000kVA unit uses). Comparable in product category (diesel gensets up to multi-MW scale) and target applications (utilities, industrial, construction).
• United Rentals: World's largest equipment rental company, including power and HVAC fleet. Comparable horizontal rental business model serving industrial and commercial customers, though North America-focused and far broader in equipment categories.
• Ashtead Group (Sunbelt Rentals): UK-listed parent of Sunbelt Rentals, operating large general equipment and specialty rental fleets including power generation. Comparable horizontal rental model; broader geographic scope but with some overlap in industrial/commercial power and climate rentals.
• Atlas Copco (Power & Flow division): GRS's parent group and global operator of modular temporary power, compressed air, and flow solutions. Atlas Copco's Specialty Rental division offers the same ZBP energy storage and QAC TWINPOWER product line that GRS deploys in NZ, operating across dozens of countries.
• Cummins Power Generation: Global manufacturer of diesel and gas generator sets, including the engines used in GRS's 1400kVA rental unit. Comparable product category and customer base for backup and prime power applications worldwide.

Others

• Perkins Engines: Engine manufacturer whose engines power GRS's mid-range generators (45-80kVA). Adjacent supplier relationship rather than direct competitor, but relevant for understanding the equipment ecosystem GRS operates within.
