Roger Sant and Dennis Bakke founded Applied Energy Services in 1981 to build efficient independent power plants, pioneering the then-new market for non-utility generation.

The company went public in 1991 and expanded aggressively through the 1990s, building and buying power plants across the Americas, Europe, and Asia, becoming one of the largest independent power producers before overexpansion strained the balance sheet.

The 2000s brought restructuring and refocusing under Gluski's eventual leadership, pruning international operations and repositioning around contracted generation.

The defining shift came in the 2010s and 2020s: coal retirement, renewables buildout, and the Fluence energy-storage joint venture with Siemens, which AES grew into a separate public company, repositioning AES as a clean-energy utility hybrid.

The coal-to-renewables transition is the core ESG story: the company has retired the majority of its coal capacity and targets continued decarbonization.

Green financing and carbon-reduction commitments anchor its published sustainability program.

Coal legacy: Historical environmental record on coal plants produced past litigation and remediation obligations.

International operations: Operations in markets with political risk carry standard utility-sector exposure.
