Aggreko announced the expansion of its battery energy storage system (BESS) fleet with the addition of three new models in a range of capacities. This launch introduces a small node 120 kW/120 kWh system, along with two large node configurations: trailer-mounted 1 MW/1.2 MWh and 1 MW/1.3MWh units.

The refreshed models in the company’s battery storage fleet reinforce its focus on designing, deploying, and optimizing engineered energy solutions for its customers across a wide variety of businesses.

By integrating advanced BESS technologies with sector-specific expertise, Aggreko delivers right-sized smart energy solutions that help customers improve efficiency, control costs, and manage emissions without compromising reliability.

The flexibility and power of these new BESS units make them particularly attractive for highly demanding and rapidly growing sectors, such as data centers. For data center operators and contractors, these engineered solutions can seamlessly integrate with diesel, gas, and renewables to overcome site capacity constraints.

The new units join Aggreko’s existing BESS fleet, which ranges from 24 kW to 1000 kW, giving customers more ways to match storage to their load. Each system can operate on its own, in parallel with other batteries, or as part of a hybrid solution with Aggreko’s generators, where the battery carries the load and the generator runs only when needed. This reduces generator runtime, fuel consumption, and maintenance. Every deployment is backed by Aggreko’s technical expertise and remote monitoring for reliable, uninterrupted operation.
