Safety, technology and company history
AES has invested in digital operations as well as generation. It has deployed an artificial intelligence safety platform across its United States operations, reporting more than a 50 percent reduction in the time needed to complete safety incident investigations, better root cause identification and improved visibility of repeat and systemic risks. An in-house innovation programme, AES Next, develops and scales technologies intended to improve the reliability of its generation and grid businesses, while the group's sustainability pages set out its work under people and communities, planet and accountability headings, covering community programmes alongside circular economy and land use topics.
The company connects its clean-energy strategy to its history: in 1989 it recorded what it describes as the first documented carbon offset programme in the United States by planting 52 million trees in Guatemala, and in 1988 it became the first independent power producer in the United States.
