Power Electrics Expands Hybrid Fleet with £2m Investment in Bespoke Dumarey BES Units
Silverstone Racing Circuit, Technology Cluster: Power Electrics, the UK’s leading temporary power provider, are excited to announce a £2 million investment in bespoke Dumarey Battery Energy Storage (BES) units, specially developed for Power Electrics with upgraded busbars for handling higher currents with better efficiency, enhancements to the firmware for smarter monitoring and modifications to the outlets to ensure the units are compatible and flexible for customer applications.
The BES units have been developed by Dumarey Green Power, and load tested at their location in the heart of the Silverstone Technology Park, a global destination for innovation and engineering. The Powerskid Ultra units are a second-life battery energy storage system with a continuous power output of up to 160kW depending on configuration. They are specifically designed for mobile and off-grid applications, such as building sites, manufacturing, infrastructure projects, filming locations and off-grid electric vehicle charging stations. They are also ideal for grid support, renewable storage and energy trading.
Commenting on the investment, Andy Pullin, CEO of Power Electrics, said: “Continuing our commitment to Green Technology is integral to our vision of being the trusted partner of choice for sustainable, reliable power solutions. Our collaboration with Tier 1 manufacturer, Dumarey Green Power, enables us to deliver the most cutting-edge and environmentally responsible power solutions on the market, through our future-proofed fleet.”

The 200kVA / 400kWh units are a game changer in size, weight and performance and are already heading out the door to support customers nationwide, from construction sites to major infrastructure projects. This investment highlights Power Electrics’ commitment to sustainability and demonstrates that they are building a resilient business for the long term, investing to ensure customers have greater access to cleaner, smarter power solutions across every sector, while reducing their environmental impact.

“We are proud to supply Power Electrics with their first PowerSkid units.” Says Managing Director Tobias Knichel - Dumarey Green Power. “Known for outstanding customer service and trusted nationwide in temporary power, Power Electrics are a natural partner for Dumarey’s advanced battery systems. Power Electrics shares our vision for second-life battery solutions. By repurposing batteries, PowerSkids carry much lower emissions and are particularly effective where large amounts of energy need to be stored. Together, we are powering a cleaner future.”
With this continued investment in their fleet of green technology, Power Electrics will be better placed to bring the benefits of BES units to even more customers across the Construction, Manufacturing, Facilities, Healthcare, and utilities sectors, including:
- Reduced C02 and N0x emissions
- Significantly reduced fuel costs if used alongside a diesel generator – instead of a generator running constantly, a BES can store energy and release it when needed. This allows the generator to run less often and only at optimal load, saving fuel
- Silent power - these units are up to 8x quieter than a standard diesel generator
- Longer runtimes and fewer fuel stops – hybrid integration works seamlessly with generators to reduce fuel use and extend generator life
- Renewable Energy Support – stores intermittent solar and wind energy to use when needed
