AES is one of the world's leading power companies.

Every day, around the globe, our 30,000 people generate and deliver the electricity that accelerates businesses, energizes hospitals and schools, and elevates the quality of life for millions of people.

We founded our company in 1981, based on the principle that empowered people can achieve remarkable success. Today, with businesses in 27 countries, we continue to improve and expand our global power services through great people, solid operations, and strong financial results.

AES stands for power.

History

AES is a young company – just over two decades old – but has compressed an enormous amount of excitement into that time. We have grown faster than most companies have ever dreamed of, have experienced our triumphs and trials, and now face the future stronger and more optimistic than ever.

Roger Sant and Dennis Bakke founded AES in 1981 after having worked together in the federal government – Roger at the US Federal Energy Administration and Dennis at the US Office of Management and Budget – during the 1973 Arab Oil Embargo, and later at the Carnegie Mellon Energy Productivity Center. AES initially focused on generation partnerships with steam- or electric-powered industrial plants, convinced that they would prefer to work with an independent power supplier rather than make capital investments for co-generation plants themselves.

By the mid-1980's, AES was providing electric utilities with power under a long-term contract price that was below the utility's "avoided cost," while also providing steam to industrial customers. During this period, AES applied new, often cleaner, power generation technology (e.g., coal-fired fluidized bed boilers) than utilities were using at the time. The company also established its trademark project structure in many of its businesses, with significant reliance on "non-recourse" project financing, a loan structure designed to distribute the risks and benefits of a project among several stakeholders.

With reforms in United Kingdom's electric sector in the late 1980s, AES began its global expansion with the quest of demonstrating how competition in the electric sector could provide lower cost and more reliable electricity supplies. Early in the 1990s, AES entered the Argentine market. Soon we were operating in Pakistan, China, Australia and Kazakhstan. By 1995 AES had become "The Global Power Company" with 19 plants in six countries. Further international expansion took place in 1996 with successful acquisitions of both distribution companies and electric generating companies in countries such as Hungary and Brazil.

AES was added to the S&P 500 in 1998, and in 2000 the stock price exceeded $70 per share. The period was characterized by unprecedented growth, including the acquisition of Electricidad de Caracas in Venezuela and Gener in Chile, and assuming control of two regional electricity distribution companies in Kazakhstan.

2001 and 2002 brought numerous challenges, including the global markets downturn and the collapse of many in the sector. AES responded by launching a turnaround program, and by 2003, was on sound financial footing and looking toward the future.

AES today still seeks to be the world's best power company, now generating and distributing electric power to 11 million people, with generation facilities in 27 countries around the globe.
