MEMS Power Generation is expanding access to its cleaner generator hire services across the UK, enabling organisations to lower emissions while ensuring secure and efficient temporary power. The enhanced offering features Stage V generators, battery energy storage solutions, Load on Demand capabilities, and generators approved for Hydrotreated Vegetable Oil (HVO) fuel.
Throughout 2025, MEMS customers are on course to reduce CO₂e emissions by thousands of tonnes through the adoption of HVO and other renewable fuels. This transition is helping key sectors such as healthcare, manufacturing, and critical infrastructure to meet sustainability goals without impacting performance.
“Many sites can now make a measurable reduction in their environmental impact without changing how they operate,” said Mark Diffey, Director, MEMS Power Generation. “Cleaner fuels and advanced technology mean temporary power can be both dependable and responsible.”
The MEMS Cleaner Options portfolio is designed for varied operational needs, particularly in urban and environmentally sensitive areas. Stage V generators meet the latest emission standards, battery energy storage reduces generator runtime and noise, and Load on Demand technology matches power output to real-time demand, cutting unnecessary fuel use and emissions.
HVO fuel, produced from 100% renewable raw materials including waste and residues such as vegetable oils, animal oils, and animal fats, offers a practical drop-in alternative to diesel. HVO can cut greenhouse gas emissions by up to 90% compared with conventional diesel, with no engine modifications required in compatible units.
“We’re investing in practical solutions that support customer sustainability goals,” added Mark Diffey. “From proven CO₂e savings with HVO to advanced Stage V and hybrid systems, we aim to make lower-emission power an everyday option nationwide.”
MEMS sustainability strategy goes beyond fuel choices. The company’s environmental commitments include waste reduction, recycling, logistics optimisation to reduce vehicle movements, and telemetry-enabled fleet monitoring for efficiency. MEMS is also exploring future technologies such as hydrogen fuel cells to further decarbonise temporary power.
One recent nine-week project saw MEMS supply a 200 kVA generator, 3,000-litre bulk fuel tank, and full distribution cabling to restore power within four hours of a customer outage. After load profiling, a 45 kVA Battery Energy Storage System (BESS) was installed, with MEMS Connect remote monitoring active throughout. Over the final 31 days, the hybrid setup reduced projected fuel use from 5,888 litres to 3,346 litres, saving 2,542 litres and avoiding 6,813 kg of CO₂e – a 43.17% emissions reduction.
