Aggreko has added three models to its Battery Energy Storage System (BESS) fleet: a 120kW/120kWh small unit and two trailer-mounted 1MW units with 1.2MWh and 1.3MWh capacity. The Houston-based announcement came on November 4, 2026. The company says the units suit fast-growing sectors such as data centres. They can work with diesel, gas, and renewables to ease site capacity limits or stand in for delayed grid connections. The 120kW unit is built for low noise and can support large motor starts, such as tower cranes. The 1MW units are containerised and mobile, with zero CO2 emissions. The new models join a fleet ranging from 24kW to 1,000kW. Paired with generators, the batteries carry the load so generators run only when needed, cutting fuel use and maintenance.

Aggreko's private equity owners are raising $1.15 billion through an add-on to its term loan B due in May 2031. The funds will pay down $395 million of its revolving credit facility, add $205 million in cash, and fund a $550 million dividend payment. The transaction, expected to complete today, is projected to generate $120 million in EBITDA based on $600 million invested for growth capital expenditure in 2026. The dividend reflects strong business performance, with revenues of $3,194 million and adjusted EBITDA of $1,218 million in the 12 months to September 2025. Aggreko's owners said increased investment in fleet and capabilities underpins organic growth, whilst mergers and acquisitions have become a proven growth pillar. Recent acquisitions are performing well with a healthy pipeline of future opportunities.
