Ampla Energia e Serviços is an electric energy distributor, controlled by Enel Brasil. Since 2016, Ampla Energia e Serviços has started using the brand Enel Distribuição Rio.
The use of this brand is part of the corporate standardization measure adopted by Enel Brasil and includes other companies in the group.
The company distributes energy to more than 66 municipalities in the state of Rio de Janeiro, which corresponds to over 70% of the territory of Rio.

In this way, Ampla Energia e Serviços serves about 3 million consumer units, which corresponds to around 8 million inhabitants.
The company has a total of 1,046 employees and is listed on the stock exchange in the Public Utility sector and in the Electric Energy segment.
An important detail is that more than 99% of the voting capital of the company is in the hands of its controlling shareholder, with only the remaining shares available for trading on the Brazilian stock exchange.
All of the company's shares are ordinary and have an 80% tag along.
The holding Enel Brasil, which controls Ampla Energia e Serviços (now Enel Distribuição Rio), was officially founded in Brazil in 2005. However, the company's history began much earlier.
This is because Enel was founded in 1962 in Italy. In 1966, Enel acquired Ampla Energia in a privatization auction.
After this acquisition, several others were carried out over the years, allowing for the expansion and diversification of the company's product catalog. As early as 1996, Ampla's shares began to be traded on the Brazilian stock exchange.

After Ampla Energia e Serviços was acquired by Enel, some of its services were transferred to Endesa and Prátil. Some of the transferred services included: insurance, home assistance, capitalization bonds, and dental plans.
In 2005, Enel Brasil was established to centralize the equity holdings of the Enel group in Brazil through a holding company. This prepared the company for future expansions.
In 2007, Enel, then the indirect controlling shareholder of Enel Brasil, began consolidating its stake in the Brazilian holding.
Through a public offering abroad, Enel SpA purchased all the shares issued by the Spanish Endesa, which at the time was the indirect controlling shareholder of Enel Brasil.
By 2009, Enel's control over Enel Brasil was expanded through the acquisition of 92.06% of Endesa's share capital and voting rights.

A few years later, in 2014, Enel acquired Endesa's stake in companies in Latin America, which included Enel Brasil. As a result, the Spanish company was excluded from the Brazilian stock market.
In 2018, the company was recognized by the Exame Sustainability Guide as the Most Sustainable Company of the Year.
This recognition stems from the fact that the company has a high commitment to working with renewable sources, pays attention to climate issues, and has over 250 income-generating projects created by the company.
