Light, more than one hundred years old, began its activities on July 17, 1899, through the Parnaíba Hydroelectric Power Plant, in Tietê river, built between 1899 and 1901.


In order to operate in Brazil's federal capital city at that time, The Rio de Janeiro Tramway, Light and Power Co. Ltd. was founded in Toronto, on June 9, 1904, and was authorized to operate in Rio de Janeiro on May 30, 1905. In that same year, the company acquired the share control of the gas lighting concessionaire, the Belgian Société Anonyme du Gaz de Rio de Janeiro, a service that was controlled by Light until 1969, when it was transferred to the state government and when the most modern hydroelectric power plant in the country started to be built, the Fontes Power Plant, located in the city of Piraí, state of Rio de Janeiro.


On July 30, 1907, the Company, through Light, started to provide stable and safe electric power supply to Rio de Janeiro. In that same year, Light acquired and unified several urban tram companies that operated in the city, controlling the service until 1963, enlarging the urban area of Rio de Janeiro, and contributing to give rise to several neighborhoods, such as Leme, Copacabana, Ipanema and Leblon.


In addition to the trams, in 1918 the Company invested in electric buses that traveled through Avenida Rio Branco until 1927. In the previous year, the Company created the Viação Excelcior, the modern buses with bells and conductor and by the end of the 20s the double-decked buses. During that period the Company also started its telephony operations, until services started to being provided by the federal government in 1966.


After the period under federal government administration, Light was privatized, through an auction held on the Rio de Janeiro Stock Exchange on May 21, 1996, and its share control was transferred to a consortium composed of three multinational companies - Electricité de France (EDF), AES Corporation and Reliant Energy - and Companhia Siderúrgica Nacional (CSN). In February 2002, the corporate restructuring process was concluded, consolidating EDF as parent company of Light.


In 2005, Light concluded its deverticalization process, giving rise to the holding company Light S.A., parent company of the three operational companies: Light Energia S.A., liable for generation/transmission; Light Serviços de Eletricidade S.A., liable for distribution, and Light Esco Ltda. liable for commercialization, thus, composing the Grupo Light (Light Group).


On March 28, 2006, a Share Purchase and Sale Agreement was entered into between EDF International S.A. (EDFI) and Rio Minas Energia Participações S.A. (RME), composed of Companhia Energética de Minas Gerais (Cemig), Andrade Gutierrez Concessões S.A. (AG Concessões), Pactual Energia Participações S.A. (Pactual Energia) and Luce Brasil Fundo de Investimentos em Participações (Luce). Thus, on August 10, 2006, the shares issued by Light and the quotas representing the capital stock of Lidil Comercial, owned by EDF, were transferred to RME-Rio Minas Energia Participações S.A., who become the new parent company of Light Group.


On February 12, 2008, the Extraordinary General Meeting of Equatorial Energia S.A. approved the merger of PCP Energia, a company that holds 13.06% of Light's shares through RME, into the Equatorial group. As from this moment, Equatorial is part of the controlling group of Light - RME. Said merger does not represent a transfer of control since both companies, PCP and Equatorial, belong to the same controlling company.


On December 31, 2009, following the Extraordinary Shareholders' Meeting the disproportionate partial spin-off of RME into three entities was approved. That action was followed by the incorporation of those split-offs by Companhia Energética de Minas Gerais (CEMIG), Andrade Gutierrez Concessões S.A. and Luce Empreendimentos e Participações S.A. (LEPSA).


On March 25, 2010, Cemig acquired from Andrade Gutierrez Concessões S.A. ("AGC"), the total of 25,494,500 common shares issued by the Company, representing 12.50% of its total and voting capital. On November 17, 2010, Cemig acquired the remaining 0.53% interest held by AGC. With that, Cemig now holds a direct interest of 26.06% in the Company.


On May 12, 2011, Parati S.A. - Participações em Ativos de Energia Elétrica ("Parati") acquired from the Fundo de Investimento em Participações - PCP ("FIP PCP") 58,671,565 common shares, representing 54.08% of the total capital of Redentor Energia S.A. ("Redentor"), indirect shareholder of the Company, through its controlled company RME - Rio Minas Energia Participações S.A., which holds 13.03% of the Company's capital.


On January 11, 2013, Light S.A. and Light Energy S.A. ("Light Energia" and, jointly with Light, the "Companies") announced to the market in general that on that date Light Energia was granted by the Brazilian Securities and Exchange Commission (CVM) its registration as a publicly-held company, category "B".

In 2013 the Light Legal project was consolidated. The project represents an important step taken by the company to fight commercial losses. In addition to electronic measuring, the project is applied in small areas called "Área de Perda Zero" (loss area zeroed) or "APZs", with approximately 15,000 customers, and high levels of commercial losses and delinquency. During the year, the Light Legal project covered a total of 26 areas and 416,000 customers, showing significant results.

In generation, Light successfully renegotiated Light Energia's interest in the capital stock of Renova Energia with RR Participações and CEMIG Geração e Transmissão. This transaction allowed CEMIG GT to enter Renova's control block, enabling the acquisition of 51% of Brasil PCH's stock and strengthening Renova's cash to be allocated to wind power projects already contracted and new growth opportunities in renewable energy assets. After the transaction, Light Energia will hold between 11.7% and 15.9% of Renova Energia's capital stock.

On August 8, 2013, Light returned the concession of UHE Itaocara, as the period remaining for the power plant's implementation and operation does not ensure a profitable operation.


On January 28, 2014, Light S.A. announced a shareholders' agreement between the Company and Furnas Centrais Elétricas S.A. ("Furnas") related to the management of the special purpose entity Energia Olímpica S.A. ("SPE Energia Olímpica"), whose purpose is the implementation, construction, operation and maintenance of a substation to supply electricity to the Rio de Janeiro Olympic Park.

On May 9, 2014, it was approved the contracting of the supply of equipment and services for the automation of aerial and underground networks through an Integrated System, using Smart Grids and Devices ("Smart Grid Project"), in its subsidiary, Light Eletricidade S.A. This equipment has the purpose of covering measuring and automation devices, allowing real-time analysis and contributing directly to reduce non-technical losses and delinquency, in addition to improving data management and quality.

In June and July 2014, Light came to prominence supplying energy during the World Cup. The organizational structure included approximately 1,000 professionals. Based on good strategic planning and tactical scheme, field teams located in strategic positions were responsible for inspections and preventive maintenance.

On July 24, 2014, Light S.A. sold 100% of its interest in CR Zongshen E-Power Fabricadora de Veículos S.A. ("E-Power"), equivalent to 20% of E-Power's capital stock, to CR Zongshen Fabricadora de Veículos S.A. ("CR Zongshen"), extinguishing E-Power's shareholders' agreement between the Company and CR Zongshen, without any remaining obligations for the signatory parties.


On April 30, 2015, the Consortium UHE Itaocara, comprising the subsidiary Itaocara Energia Ltda., with a 51% interest, and Cemig Geração e Transmissão S.A., with the remaining 49%, was declared the winner of the A-5 Auction held by ANEEL, related to the Itaocara I hydroelectric power plant.  The project will be built in the Paraíba do Sul River and will have an installed capacity of 150.0 MW, and assured energy of 93.4 MW average. The UHE Itaocara Consortium destined 95.5% of its assured energy to the Regulated Contracting Environment, at a selling price of R$ 154.99/MWh, with the Power Purchase Agreement starting in January 2020, and a supply period of 30 years. Operations are believed to start in the second quarter of 2018, and the total estimated investment is of R$ 1 billion.
