Rolls-Royce is broadening its energy portfolio through the introduction of advanced mtu gas engines, which boast a fast-start capability. These engines are particularly suitable for powering data centres and stabilising the power grid.
Set to launch in 2026, the new 20-cylinder mtu Series 4000 L64 engine targets the 60 Hz market, primarily North America, and delivers a full output of 2.8 Megawatts in just 45 seconds, marking a ten percent performance enhancement over its predecessor. The latest version eliminates the need for a gearbox, resulting in substantial space savings for data centre operators. Current models of the mtu Series 4000 gas gensets are already available worldwide, offering a 120-second fast-start capability for both 50 Hz and 60 Hz markets.
The fast-start mtu gas gensets can deliver emergency power to data centres, serve in continuous power roles, or work alongside mtu diesel gensets. The continuous power application is crucial when the existing grid cannot handle the additional demand a new data centre may impose. Utilising an independent gas power plant can facilitate faster online integration, improve energy security, and offer additional revenue opportunities by feeding excess electricity into the grid. These generators boast a long life, with an impressive 84,000 hours before requiring overhaul, and are available in a compact container form.
mtu gas units are capable of reducing emissions such as nitrogen oxides and CO2 while enhancing efficiency in power generation. They can operate on sustainable fuels like biogas and biomethane, and future operation with 100% hydrogen or a hydrogen mix is possible as green hydrogen becomes available.
mtu gas gensets are currently operational in many data centres, including SpaceDC's campus in Jakarta. Powered by Rolls-Royce technology, they ensure efficient and clean base load and emergency power supply.
Modularity is key to managing the strains of today's power grids, which are stressed by large data centres and fluctuating renewable energies. Globally, mtu gas engines already provide reliable power and heat, from supporting peak loads in Alberta, Canada, to powering a substantial fleet in the UK.
