Aggreko has added three new Battery Energy Storage System models to its fleet, including a 120 kW/120 kWh unit and two trailer-mounted systems rated at 1 MW with 1.2 MWh and 1.3 MWh capacity. The announcement was made November 4, 2026.
Why it matters
The new models target rapidly growing sectors such as data centers, where battery systems can substitute for delayed or limited grid connections. Companies facing power constraints have an additional option for on-site energy supply.
The smallest new unit is rated 120 kW/120 kWh and carries a 544A pass-through, while the larger trailer-mounted units deliver 1 MW with 1.2 MWh and 1.3 MWh capacity. The 1.3 MWh unit includes built-in HVAC and fire suppression, and the 1.2 MWh unit is rated for zero CO2 emissions.
The players
Aggreko
Aggreko is a global provider of temporary power, temperature control and energy solutions, employing approximately 8,000 people and active in more than 80 countries.
The details
Each new system can operate alone, in parallel with other batteries, or in a hybrid configuration with generators, where the battery carries the load and the generator runs only when needed. The 120 kW unit is trailer-mounted and designed for low noise levels, and each deployment is backed by technical expertise and remote monitoring.

Roadmap
The expansion extends Aggreko's existing Battery Energy Storage System fleet, which already spans 24 kW to 1000 kW, into larger trailer-mounted units. The move reflects a broader push by temporary-power providers to offer battery storage alongside traditional generators for electrified and grid-constrained sites.
Businesses and facilities needing temporary or supplemental power can consider battery systems that run quietly and can operate alone or alongside generators. The hybrid option lets users reduce generator run time when a battery can carry the load.
The takeaway
Battery storage is increasingly positioned as a practical alternative when grid connections are delayed or limited. Organizations weighing power options can compare battery, generator and hybrid configurations against their site requirements.
