History and Background
Founding and Early Years
The origins of Aggreko trace back to 1944, when the company was founded in the United Kingdom as a subsidiary of the G. J. G. Smith Company. Initially, the focus was on providing standby power for industrial facilities. During the post‑war period, the company expanded its product line to include diesel generators and mobile power systems for military and commercial use. In the 1960s, Aggreko introduced its first portable generation set, which could be transported by road or rail to remote locations.
Throughout the 1970s and 1980s, Aggreko grew its presence in the United States and Europe. The company diversified into the mining sector, supplying power to underground operations, and entered the renewable energy market by integrating solar and wind components into temporary power solutions. By the end of the 1990s, Aggreko had established a fleet of more than 2,500 generators and had begun to standardize its product lines across key markets.
Expansion and Globalization
The early 2000s marked a period of aggressive expansion for Aggreko. The company pursued strategic acquisitions to broaden its capabilities and geographic reach. Key acquisitions included the purchase of a U.S.-based generator rental firm in 2003, a South African power services company in 2006, and an Australian mobile power supplier in 2008. These acquisitions provided Aggreko with access to new customer bases, expanded its engineering expertise, and increased its capacity to serve large-scale projects in the Americas, Africa, and Oceania.
During the same decade, Aggreko introduced its “Power Hub” concept, a modular platform that combined generator units with battery storage and control systems. This innovation allowed customers to deploy a complete power package within hours, reducing downtime and logistical complexity. The company also began to invest in digital technologies, deploying remote monitoring and predictive maintenance solutions to improve asset performance and uptime.
Corporate Structure and Governance
Aggreko’s corporate structure is organized around a board of directors and a senior management team. The board is responsible for strategic oversight, risk management, and shareholder relations. Key governance practices include a compensation committee, an audit committee, and a nomination committee, each chaired by independent directors. Aggreko adheres to the UK Corporate Governance Code and complies with the European Union’s regulatory frameworks for public companies.
Operationally, the company is segmented into three core business units: Power Generation, Power Transmission, and Power Storage & Service. Each unit is led by a regional head who reports to the Chief Executive Officer. The company maintains a global supply chain that sources engines, alternators, and control systems from leading manufacturers, ensuring that its fleet remains technologically advanced and compliant with international emissions standards.
