AES Brand Guidelines: Applied Energy Services, 1981, and a Power Company in Many Countries

Two former energy officials and a consultancy.

AES began as a consultancy. English Wikipedia says the company was founded on 28 January 1981 as Applied Energy Services by Roger Sant and Dennis Bakke, who had both been appointees at the Federal Energy Administration. The company’s own history describes it in 1981 as “an energy consulting company,” with Sant as its first chief executive and chairman.

The consultancy soon became a builder and owner of power plants. AES says that by 1988 it had become an independent power producer, building and running its own plants. English Wikipedia says the company became AES Corporation and went public in 1991; AES says its shares were listed on the New York Stock Exchange that year under the ticker AES. Bakke became president in 1987 and chief executive in 1994, according to English Wikipedia.

The early company was known for an unusual internal culture. English Wikipedia says its founding values included environmental responsibility and an explicit goal of having fun, and that until the early 2000s it practised a form of self-management that handed much responsibility to ordinary employees under a decentralised system. Something of that language survives: the company’s values page today still talks about having fun solving meaningful challenges as a team.

The short name became the brand. The company presents itself as AES, The AES Corporation in its legal name, with its headquarters in Arlington, Virginia, English Wikipedia says.

From Argentina to Vietnam.

The 1990s and 2000s turned AES into an international company. Its own timeline lists a string of entries: Argentina in 1993 with the San Nicolás plant; the Dominican Republic in 1997 with Los Mina; El Salvador and Panama in 1998, the same year it bought the Southland plant in California; Chile and Colombia in 2000 through the purchase of Gener; Puerto Rico in 2002; the Maritza thermal plant in Bulgaria, begun in 2006; Vietnam in 2008 with the Mong Duong 2 project; and Jordan in 2009 with the Amman East plant. English Wikipedia says Bakke and Sant oversaw the building of power plants in 29 countries. One venture, the purchase of the Tbilisi distributor Telasi in Georgia, became the subject of the documentary film Power Trip, directed by Paul Devlin.

AES also became a utility owner in the United States. It bought Indianapolis Power & Light, or IPALCO, in 2000 according to English Wikipedia, or 2001 by the company’s own timeline, and Dayton Power & Light in Ohio in 2011. In February 2021 both were renamed, English Wikipedia says: Indianapolis Power & Light became AES Indiana, and Dayton Power & Light, keeping its legal name, became AES Ohio. The company today lists regulated utilities in Indiana, Ohio and El Salvador.

Leadership changed after a difficult period. English Wikipedia says Bakke resigned as chief executive in 2002 during a liquidity crisis that followed the collapse of Enron, that Sant stayed as executive chairman until 2003, and that Paul Hanrahan then led the company for about a decade. Andrés Gluski followed him; AES dates his appointment to 2011, English Wikipedia to 2012. English Wikipedia says Gluski cut the number of countries where AES works from 28 to 16. The company’s timeline adds the solar developer sPower, bought with the Alberta investor AIMCo in 2017, and Fluence, an energy-storage venture launched with Siemens in 2018.

How power producers present themselves.

Independent power producers sell something nobody can see, so they lean on the places that make it. Their websites and reports tend to draw on a familiar set of pictures: gas turbines in clean halls, cooling towers against a pale sky, the domes of nuclear stations, rows of wind turbines and solar panels caught at dawn, and control rooms where operators watch walls of screens. The plant stands in for the product.

Many of these companies also face households directly. In the competitive retail markets of Texas and parts of the Northeast and Midwest, a single generator may own several retail electricity brands, each with its own name and look, alongside the parent’s corporate name. Vistra and NRG Energy both present themselves this way, as a “family” of brands, and some of those names are older than the parent that now owns them: TXU became the Texas company’s name in 1999, Vistra in 2016.

A newer theme is the long-term power contract with technology companies. In 2026, World Nuclear News reported 20-year agreements under which Amazon Web Services and Meta buy output from Vistra’s nuclear plants, and such deals now sit beside data-centre pages and press releases in the way these companies describe their future.

The rest of the visual record is practical: community and safety pages, plant fact sheets, sustainability reports and investor decks built around capacity charts measured in megawatts and gigawatts. This guide sets out what can be checked about each company — where it came from, who owns it and what it runs — and marks clearly where a statement is the company’s own.

A listed company with a pending take-private.

AES describes itself today as an investor, owner and operator of power generation, utilities and liquefied natural gas infrastructure, with a fleet that includes solar, hydro, wind, natural gas, coal and battery storage. Its website names Andrés Gluski as chairman and chief executive. Much of its recent story concerns technology customers: the company lists a partnership with Microsoft in 2021 to bring renewable power to data centres and a 650-megawatt power purchase agreement with Meta in 2025, and POWER magazine reported in March 2026 that AES had told investors it held 8.2 gigawatts of signed agreements with data-centre customers.

A change of ownership is under way but not complete. On 2 March 2026 a consortium of Global Infrastructure Partners, now owned by BlackRock, the EQT Infrastructure VI fund, the California Public Employees’ Retirement System and the Qatar Investment Authority announced a definitive agreement to take AES private, POWER reported on 4 March 2026; the companies said they expected to close in late 2026 or early 2027, subject to shareholder and regulatory approvals. AES stockholders approved the merger on 26 June 2026, The Globe and Mail reported, with other federal, state and foreign approvals still outstanding. The deal was agreed in March 2026 and had not been completed at the time of writing, so AES remains a listed company. POWER reported that its Indiana and Ohio utilities would remain regulated under the agreement.

The brand itself has moved towards the short name. Where the subsidiaries once carried local utility names, they now carry the three letters, as AES Indiana and AES Ohio show, and English Wikipedia lists AES Andes among its major subsidiaries. The company runs local websites for markets including Bulgaria, Chile, Colombia, Mexico, Panama, Puerto Rico and Vietnam.

For a design guide, AES shows how a consultancy’s initials can become a single name across many countries and utilities. Compare Engie, another international power group, and NextEra Energy, another US power company. For this guide we use a dusk violet, a solar amber and a pale lilac with a sans, an unofficial interpretation; no product or logo is reproduced.
