The GNA I thermoelectric power plant is located in Porto do Açu, in the state of Rio de Janeiro. Thermal plant that will start operating will be powered by natural gas
Yesterday, Wednesday (15/09), Aneel – National Electric Energy Agency authorized the entry into operation, as of today (16), of the thermoelectric plant GNA I. The facilities are located in Porto do Açu, in São João da Barra, in the state of Rio de Janeiro. The UTE will be powered by natural gas and will have the capacity to produce 1.338,30 megawatts (MW), enough to serve 4 million people.

Start of commercial operation of the thermoelectric plant, in the face of a water crisis
The general director of Aneel, André Pepitone, says that the entry of this thermoelectric plant will be very beneficial for the sector, especially in the current situation. The energy generated by the UTE located in Porto do Açu, will be injected into the system in the Southeast region, the most affected by the drought in the reservoirs, being enough to serve 4 million inhabitants, emphasizes the executive.
The water crisis caused by the lack of rain consequently generates a drop in water storage in the reservoirs of the hydroelectric plants and the National Electric System Operator (ONS) had to activate thermoelectric plants to guarantee the supply of energy to the country. The energy generated in thermoelectric plants, however, is more expensive and causes an increase in the cost of the electricity bill. At the end of August, the government and the National Electric Energy Agency (Aneel) announced a new tariff flag level.

The UTE GNA I project, in Porto do Açu
The GNA I Thermoelectric Plant, located in Porto do Açu, in the municipality of São João da Barra, in the state of Rio de Janeiro, is made up of 3 gas turbines and 1 steam turbine which, together, will be responsible for generating 1,3 GW in a combined cycle, which contributes to increased efficiency in power generation.
The energy generated by the GNA I thermoelectric plant, authorized yesterday (15/09), by Aneel to enter into commercial operation, will be connected to the SIN – National Interconnected System – through a 345 kV Transmission Line of approximately 52 km in length, at the Campos dos Goytacazes substation.

On the last 6th, in news published by Valor Econômico newspaper, Eneva is going to build a thermoelectric power plant in the interior of the state of Amazonas. The company purchasing Campo de Azulão for natural gas exploration, in Silves, in the state of Amazonas, foresees an investment of R$ 100 to R$ 120 million and the construction of the new plant should be ready by next year. As a result, the thermoelectric plant will be built near Azulão, where Eneva will drill for new gas extraction villages.
According to the company's director of operations, Lino Cançado says that “We have been working with other projects on land and also with gas from LNG and pre-salt. We have the competence to put projects on their feet, do basic engineering, market research, auction participation and implementation and operation and maintenance (O&M). It is only natural that we have the ambition to participate in this”.
In Parnaíba, where the company has an installed capacity to generate 1,4 GW, Cançado stated that he intends to renew the contracts for the thermoelectric plants. On the other hand, he explained that he will not make new investments in the region. In the Paraná Basin, where the company acquired four blocks in 2020, operations have yet to start. The contract, however, provides for activities until 2029 for the minimum exploratory program in the region.
