Parnaíba Complex

Parnaíba Complex

The Parnaíba Complex has a total installed capacity of 1.9 GW, of which 1.4 GW is already in operation. The Complex comprises 6 gas-fired thermoelectric power plants (Parnaíba I, II, III, IV, V and VI) and 10 land-based fields located in their adjacency.

Energy generation

The power plants are connected to the North Subsystem of production and the energy transmission network of the National Interconnected System (Sistema Interligado Nacional in Portuguese. Acronym: SIN).

The Parnaíba I, II, III, V and VI power plants have agreements in the Regulated Market (ACR), in which generators sell energy to distributors through auctions organized by the regulatory agency, ANEEL. These are long-term agreements, which guarantee a fixed compensation to the generating agent (protected against inflation), regardless of generation, plus variable compensation when there is dispatch.

The Parnaíba IV power plant is the only operational power plant operating in the Free Market (ACL), under the “Merchant” framework.

The Parnaíba II power plant operates on a combined gas cycle, that is, it uses the heat generated by the combustion of gas, in gas turbines that operate in an open cycle and reuses it for energy generation, through steam power plants. With this, it is possible to generate more energy without the additional use of gas molecules, thus increasing the thermal efficiency of the system. The Parnaíba V and VI power plants, currently under construction, will also operate on a combined cycle.


Eneva has nine fields declared commercial in the Parnaíba Basin, in Maranhão. Of this total, five are in production – Gavião Real, Gavião Vermelho, Gavião Branco, Gavião Caboclo and Gavião Azul – and four are in development – Gavião Preto, Gavião Branco Norte, Gavião Tesoura and Gavião Carijó. The company also has assets in the discovery evaluation phase and exploratory blocks acquired in ANP’s 13th and 14th Bidding Rounds, currently in the exploratory drilling and seismic phase, respectively, in addition to blocks acquired in the First Permanent Offer Cycle, carried out by the ANP in 2019, and, more recently by the end of 2020, 7 exploratory blocks in the onshore Amazonas and Paraná Basins, also the Juruá Field, in the Solimões Basin, during the Second cycle of ANP’s Open Acreage.

Eneva’s total current gas production capacity in the Parnaíba Basin is up to 8.4 million m³/day, and is fully connected to energy generation, that is, the gas is produced according to the demand of the Parnaíba Complex’s thermoelectric power plants. Non-associated gas on land is more competitive in terms of discovery costs, development and production per cubic meter, resulting in energy generation at more attractive costs for the Brazilian electrical system.

In addition, the company has 31.8 bcm of remaining reserves (2P) certified by Gaffney Cline & Associates (Natural Gas Reserve Certification Report of December 2020) and a 203 km long pipeline network.

Azulão-Jaguatirica Integrated Project

Azulão-Jaguatirica Integrated Project

*Data as of August,2020

The project consists on the extraction, production, treatment and liquefaction of gas in the Field of Azulão, in the State of Amazonas, which will be transported in cryogenic tanks to an area adjacent to the Jaguatirica TPP, located in Boa Vista, in the State of Roraima, by 1,100km of paved roads currently used to transport other goods.

Azulão is a natural gas field located in the Amazon Basin, in the State of Amazonas. The field, purchased by Eneva in 2018, has a volume of certified reserves by an independent consultancy: Gaffney, Cline & Associates, of 5.9 billion cubic meters of natural gas (2P), which is a sufficient volume to guarantee 100% dispatch of the Jaguatirica II TPP during the entire period of the agreement, if necessary.

The Jaguatirica II thermoelectric power plant, under construction in Boa Vista, State of Roraima, has an installed capacity of 141 MW. The TPP was the winner in ANEEL’s 2019 Auction for the Supply to Boa Vista and connected locations. The agreement established in the auction provides that the Jaguatirica II TPP will have a commitment to deliver 117 MW, fully flexible, by the period of 15 years, starting June 2021. Its annual fixed revenue will be adjusted annually under the IPCA. Additionally, when dispatched, the power plant will receive variable revenue equivalent to fuel costs and variable operation and maintenance costs.

Eneva will develop the gas production and thermoelectric generation in an integrated manner, thus replicating, in a new geography, the R2W (Reservoir-to-Wire) business model successfully implemented at the Parnaíba Basin.
