Company Profile and Ventures

ENEVA is an integrated power generation company, which develops and operates joint electric energy generation and hydrocarbon exploration and production businesses in Brazil. The Company is a reference in the power segment because it is a pioneer in adopting the reservoir-to-wire business model. ENEVA has a thermal complex with installed capacity of 2.8 GW (78% operational), representing 11% of Brazil’s gas thermal capacity. In addition, ENEVA is the second largest natural gas operator in Brazil, with a production capacity of 8.4 million m³/day. The Company operates in the Parnaíba Basin, predominantly located in the State of Maranhão, in a total area of 52,000 km², through concession agreements to explore and produce hydrocarbons.

Parnaíba Complex

The Parnaíba Complex is the pioneering development of the reservoir-to-wire (R2W) model in Brazil. Fuel to the power generation by thermal power plants is directly supplied by natural gas field located in the surrounding areas.

The Parnaíba Complex is comprised by the power plants (i) Parnaíba I; (ii) Parnaíba II; (iii) Parnaíba III; and (iv) Parnaíba IV.

The Parnaíba Complex has total installed capacity of 1.9 GW,  (1,4 already in operation) where four thermal power plants generate electricity from gas produced in fields in the surrounding areas, all located in the Parnaíba Basin, in the State of Maranhão. The complex is connected to the Northern Sub-system of the Brazilian Interconnected System (or “SIN”).

– Natural Gas Thermal Generation

In this segment the Company operates in natural gas generation of electric energy pursuant to the Electric Energy Sales Agreement in the Regulated Market – CCEAR and one Electric Energy Sale Agreement in the Free Contracting Environment – ACL.

On August 31st, 2018, the Parnaíba V CCGT, with an installed capacity of 385 MW, to be built as part of the Parnaíba Thermoelectric Complex, in the State of Maranhão, was a winning bidder the National Electric Energy Agency – ANEEL Y-6 new energy auction.

On May 31st, 2019, the thermoelectric generation project Jaguatirica II CCGT (“Jaguatirica II”), with installed capacity of 132.3 MW, to be installed in the municipality of Boa Vista, State of Roraima, won ANEEL’s Public Auction for Supply to Boa Vista and Connected Locations of 2019.

On October 18th, 2019, the expansion of the thermal power plant UTE MC2 Nova Venécia 2, with 92.3 MW additional installed capacity (“Parnaíba VI” or “Expansion”), to be set at the Complexo Termelétrico Parnaíba, in the State of Maranhão, won the 2016 A-6 new energy auction held by the  ANEEL.

– Upstream (E&P)

The Company operates in the exploration and production (E&P) of hydrocarbons in a concession area of approximately 40 thousand km² in the Parnaíba Basin, State of Maranhão. Currently, the Company has a natural gas production capacity of 8,4 million m³/day, which is fully allocated to supply the thermal complex, also owned by ENEVA. This segment is comprised by controlled company Parnaíba Gas Natural S.A. (PGN). In November 2017, PGN and Petrobrás entered into agreement of acquisition of rights and obligations over the exploration and production of hidrocarbons in Azulão land field, in Amazonas Basin. On April 30, PGN completed the acquisition.
