The Parnaíba I, Parnaíba III, and Parnaíba IV power plants have been in commercial operation since 2013, while Parnaíba II, Parnaíba V, and Parnaíba VI have been in commercial operation since 2016, 2022, and 2025, respectively.

All the plants in the Parnaíba Complex are part of the Northern subsystem of the National Interconnected System (SIN).

Located in Barra dos Coqueiros, in the state of Sergipe, the Sergipe Hub’s main operational assets include the Porto de Sergipe I natural gas-fired thermoelectric power plant (UTE), with an installed capacity of 1,593 MW, and the LNG Terminal, capable of supplying up to 21 million m³/day of natural gas.

The power plant is supplied with LNG purchased from third parties and transported by LNG carriers to the FSRU (Floating Storage and Regasification Unit).

The Sergipe Hub is connected to the Northeast Generation Subsystem and integrated into Brazil’s National Interconnected Transmission System (SIN).

Since October 2024, the Sergipe Hub has also been connected to the national gas pipeline network and has been operating in on-grid natural gas trading.

The Jaguatirica II thermoelectric power plant, in Boa Vista, Roraima, stands as Eneva’s only operating asset powered by natural gas from the Amazonas sedimentary basin.

The Integrated Azulão–Jaguatirica system process can be summarized in five stages: (1)Exploration and production of natural gas at the Azulão field; (2)Treatment and liquefaction of the produced gas, enabling storage and transportation as LNG;(3) Road transportation of LNG from the Azulão field, in Silves, Amazonas, to Boa Vista, Roraima, using trucks equipped with cryogenic LNG tanks (a distance of 1,100 km along an existing paved highway); (4) LNG storage in an area adjacent to the Jaguatirica II power plant; and (5) Regasification of LNG for use in thermoelectric generation.

Eneva has a production capacity of 0.6 million m³ dedicated to supplying the Jaguatirica II plant, consolidating the Reservoir-to-Wire model, implemented as a pioneering solution in Brazil.

The asset began commercial operation in May 2023, and the electricity generated is sold in the Free Contracting Environment through bilateral contracts and merchant agreements.

The Futura Complex also includes an expansion pipeline on the same site, consisting of the Futura II solar project (UFV 23 to 45), with an estimated installed capacity of 906 MWp.

In 2024, Eneva’s renewable portfolio accounted for 11% of installed capacity and generated 1,484 GWh of electricity.

The Fortaleza plant is a natural gas-fired thermoelectric plant developed under the Federal Government’s Priority Thermoelectric Program, with an installed capacity of 327 MW, located in the municipality of Caucaia, in the state of Ceará, in Brazil’s Northeast region.

On March 15, 2023, Termofortaleza was incorporated into Eneva Holding S.A. by the Company, in accordance with the terms approved at the Company’s Extraordinary General Meeting held on December 21, 2022.

Following the termination of its contract with the local distributor at the end of December 2023, the Fortaleza plant was shut down and remains in hibernation while the Company evaluates potential opportunities for the asset.

The acquisition of BTG’s thermoelectric assets in 2024 increased the Company’s installed capacity by 352 MW of natural gas generation.

The Viana (174.6 MW), Viana I (37.48 MW), Povoação I (74.96 MW), and Luiz Oscar Rodrigues de Melo (240 MW) plants represent 10% of Eneva’s thermal generation capacity and have the ability to supply 12% of Espírito Santo’s total energy demand, the state where they are located.

The Luiz Oscar Rodrigues de Melo plant (“LORM”) has contracted capacity of 35 MW until January 2026, a contract for 96 MW until December 2025, and another for 191 MW from July 2026 through June 2041.

In addition to its natural gas-fired plants, Eneva currently operates two coal-fired thermoelectric plants with a combined installed capacity of 725 MW: (i) Porto do Itaqui, in Maranhão (“Itaqui”), with an installed capacity of 360 MW; and (ii) Porto do Pecém II (“Pecém II”), in Ceará, with an installed capacity of 365 MW.

Itaqui and Pecém II are part of the Northern and Northeastern subsystems of Brazil’s National Interconnected System (SIN) and are currently in operation. Both plants are located near port areas and are supplied with imported coal.

As with the Company’s natural gas plants, the electricity generated by these coal-fired plants is sold in the Regulated Contracting Environment (ACR) through contracts signed with distributors in ANEEL’s energy auctions.

Eneva also owns fuel oil-fired plants acquired in the second half of 2024 as part of the transaction involving BTG’s thermoelectric assets: Geramar I and Geramar II (together, “Gera Maranhão”).

Both plants are located in the municipality of Miranda do Norte, in the state of Maranhão, and have a combined installed capacity of 331 MW.
