What Renset does

Renset Group B.V. is a Delft, Netherlands-based clean technology startup developing portable, modular battery power stations as zero-emission replacements for diesel and petrol generators used on construction sites, in festival infrastructure, and at utility/infrastructure projects. The company's core product is the PS5000 portable power station, rated at 5,000W continuous output (EU) / 4,000W (UK), with peak power up to 7,500W and surge of 10,000W, paired with four hot-swappable BM125 battery modules (12 kg each, 1,250 Wh per module, totaling 2,500 Wh rated energy). The defining technical capability is hot-swappable battery modules that can be replaced without shutting down equipment, allowing continuous operation across long shifts; the system operates below 45 dB(A), uses a rotationally moulded IP54-rated enclosure engineered for harsh weather and rough handling, and supports standard European and UK site voltages. Renset markets measurable outcomes of -90% lifecycle CO2 emissions and -80% lower operating costs compared to fuel generators.

The company was founded by Teun van 't Veer, a former seven-year employee of UK construction company Kier Group, and is connected to the TU Delft ecosystem through the YES!Delft incubator and the e4Battery academic community. Renset sells directly to enterprise customers through a field-sales motion, with website CTAs structured around demo requests and quote-based pricing rather than disclosed list prices. The company has piloted and validated the product with named enterprise customers including Kier Group, Steve Vick International, Netceed, VDL, and SGN Natural Gas, and has tested the system at the Mysteryland festival in partnership with InnoFest. The product is CE-certified for the EU and UKCA-certified for the UK.

The revenue model centers on hardware sales of the PS5000 system and BM125 battery modules to construction, event, welding, and utility/infrastructure customers. As of November 2025, the company has raised a single disclosed €600K seed round led by Vliegwiel Impact with support from repeat investors, explicitly designated to scale production and expand European deployment. Renset was recognized as a finalist and second-place winner of the Hans de Jonge Start-up Award 2024 for innovation in the Dutch built environment. No revenue figure has been publicly disclosed and headcount remains in the 1-10 range, indicating the company is in an early commercialization phase.

Core offering

Renset designs, manufactures, and sells the PS5000 portable battery power station and its BM125 swappable battery modules as a zero-emission, silent replacement for diesel and petrol generators on construction sites, utility/infrastructure projects, and live events. The system delivers 5 kW continuous power (EU) / 4 kW (UK) with up to 7.5 kW peak and 10 kW surge from four 1250 Wh hot-swappable modules housed in an IP54-rated enclosure.

Product overview

Renset offers a modular portable battery system as a clean energy replacement for diesel and petrol generators in construction and events industries. The core product is the PS5000 portable power station, which features four hot-swappable BM125 battery modules (1250 Wh each) that can be replaced instantly without interrupting power supply. The system delivers professional-grade power output (5000W continuous, up to 10kW surge) while operating silently and producing zero emissions. Built with rotationally moulded HDPE and Protalloy steel enclosure, IP54-rated for harsh environments. The modular architecture allows operators to extend runtime by carrying additional battery modules.

Scale indicators2 records

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• Anker Innovations: Anker (via Anker SOLIX) sells portable and home battery power stations at consumer scale. While more consumer-leaning, its scale, brand and supply chain make it a competitive threat if it moves up-market into professional/construction products.
• Aggreko: Aggreko rents temporary power solutions (generators, battery storage) to construction, events and industrial customers. It is the dominant incumbent that owns the customer relationship Renset must displace, and is now adding battery offerings.
• Generac: Generac is a major US-headquartered manufacturer of generators and increasingly of energy storage products. It represents the incumbent generator supplier that Renset's PS5000 substitutes in professional applications.
• Honda Power Equipment: Honda's Power Equipment division is one of the most widely deployed portable generator brands globally, including on construction sites. Its portable generators are the legacy products Renset directly competes against in jobsite applications.
• Atlas Copco: Atlas Copco is a global leader in construction and infrastructure equipment, including diesel and emerging battery-powered mobile generators. It is the incumbent whose diesel products Renset is directly displacing on construction sites.

Direct peers

• EcoFlow: EcoFlow manufactures portable and home battery power stations with high continuous output and swappable battery ecosystems. It is the most direct competitor to Renset, also selling modular professional-grade power stations aimed at jobsites and off-grid use.
• Bluetti: Bluetti produces portable lithium battery power stations ranging from consumer to industrial capacity, with hot-swap and expandable battery options. Directly comparable to Renset's PS5000/BM125 architecture and target use cases.
• Goal Zero: Goal Zero (a NRDC company) builds portable power stations and solar generators for outdoor, emergency and professional use. Comparable category of portable battery power products, though with greater emphasis on outdoor/consumer segments.
• Jackery: Jackery is a leading portable power station brand, primarily consumer-focused but expanding into higher-capacity professional products. Comparable to Renset in form factor and battery-based portable power category, though with stronger consumer branding.

Emerging players

• Zendure: Zendure develops portable and home battery power stations with modular expandable battery systems. It is an emerging player in the same portable battery category as Renset, with overlapping product philosophy but weaker presence in professional/construction channels.
