What Power Prove does
Power Prove is a Leicester, United Kingdom-based manufacturer and supplier of load bank equipment used to test and validate the performance of backup power generation and battery systems. Established in 2020 as a focused division of Cressall Resistors Ltd.—a power resistor manufacturer with over a century of operating history dating to 1920—Power Prove designs, manufactures, and sells AC load banks ranging from 6kW portable units to 500kW industrial systems, DC load banks for battery discharge testing at 3kW to 30kW, integrated radiator-mounted load banks, and a hybrid DC/AC DUAL30 unit. The company's proprietary DIGILOAD digital control system provides a touchscreen interface, precision power measurement (V, A, kW, kVA, kVAr, cosΦ), automated CSV data logging to USB, load profile memory, Modbus TCP networking for multi-unit testing, and remote diagnostics via Gigabit Ethernet or optional 4G cellular connectivity.
The firm serves industrial customers worldwide who require verification of diesel generators, UPS systems, and battery-backed emergency installations, addressing pain points such as prevention of wet stacking in diesel generators, validation of battery capacity, and compliance with fire safety regulations including BS 5266-1:2016 and the UK's Regulatory Reform (Fire Safety) Order 2005. Customer segments include power generation equipment manufacturers and operators, battery system operators across hospitals, data centres, offshore platforms and continuous process industries, and building owners and facilities managers responsible for emergency lighting compliance.
Power Prove operates a sales-led, quote-based go-to-market model with no e-commerce or self-service purchasing—all transactions begin with a quote request form on the product page or direct phone contact. Revenue derives primarily from one-time hardware sales of standardized and customized load banks, supplemented by maintenance services. The firm is privately held as a wholly owned division of Cressall Resistors Ltd., with ISO 9001:2015 quality management and ISO 45001 occupational health and safety certifications held at the parent level. The company maintains an active LinkedIn presence and a blog with content authored by Division Director Andrew Keith, who leads an experienced engineering team with deep domain expertise inherited from Cressall's long operating history.
