The Customer
S Jones Containers has a long-standing reputation for delivering secure, tailored containerised solutions to global leaders across a range of industries. One such client is Cummins, a large corporation recognised worldwide for its innovations in engines, filtration, and power generation systems.
With over 100 years of engineering excellence, Cummins operates in more than 190 countries and territories and is at the forefront of developing technologies that drive decarbonisation and energy efficiency across industrial applications. The company’s focus on sustainability and net-zero targets has led to the development of pioneering solutions that rethink how energy is generated, utilised, and recaptured.
The Challenge
As part of its broader decarbonisation strategy, Cummins sought a containerised housing solution for a state-of-the-art energy regeneration system. The aim: to recover electricity generated during diesel engine testing and feed it back into the national grid, a technically complex but environmentally critical initiative.
The system would be installed at one of Cummins’ UK sites, where it would convert test energy from large diesel generators into reusable electricity, thereby reducing waste and supporting the company’s journey toward carbon neutrality.
Our Solution
Our in-house Conversions team designed, modified, and delivered a fully containerised solution to support Cummins’ innovative energy regeneration system. Two bespoke 40ft high cube containers were configured in a stacked formation to house all required power recovery equipment within a compact, efficient footprint.
Engineered to meet strict safety and compliance standards, the build was designed to withstand the heat and electrical demands of continuous generator testing. Manufactured entirely in-house, the solution ensured full quality control, shortened lead times, and seamless alignment with Cummins’ sustainability goals
Key Features:
- Housed energy regeneration equipment, including switchgear, transformers, and cooling systems
- Enabled vertical stacking through advanced structural reinforcement and tailored engineering
- Integrated ventilation, thermal insulation, and cable routing for safe, continuous operation
- Fully manufactured in-house for reduced lead times and precise quality control
What Cummins Had To Say
“S Jones were adaptive and flexible throughout the engineering phase, especially considering the effects of Covid-19 and the lockdown at the time. Their designers were engaging and contributed creative ideas to help us achieve this challenging project.”
