We are the largest natural gas-fired thermal power complex in Latin America, with 3 GW of installed capacity located at the Port of Açu (RJ) - enough to supply 14 million households.

With two combined-cycle natural gas power plants in operation, interconnected by an LNG terminal - the only privately operated one in Southeast Brazil – we serve as a strategic player for Brazil’s energy security and a driving force in the transformation of the gas and energy sectors, integrating infrastructure, innovation, and sustainability.

Born from a joint venture between global leaders — Prumo Logística, bp, Siemens Energy, Siemens AG, and SPIC Brasil — we combine experience, infrastructure, and strategic location to develop projects that drive national growth and support the country’s energy transition.

We have an additional licensed capacity of 3.4 GW, which will allow our complex to expand to up to 6.4 GW of installed power. Our plans also include building pipelines connecting our generation complex to the national gas transportation network, as well as the construction of Brazil’s first onshore LNG storage terminal, consolidating GNA as the country’s main Gas and Energy Hub.

Growth with Responsibility

We operate with ethics, socio-environmental responsibility, and a focus on the safety of everyone involved in our activities.

During the construction of the GNA I and GNA II power plants, over 22,000 jobs were created, prioritizing the hiring of local labor and recording more than 45 million man-hours worked without any lost-time accidents. To achieve this, we invested in professional training programs aimed at local communities and suppliers, promoting job and income generation and leaving a legacy of development in the region.

With courage, innovation, and commitment, we continue to contribute to building a safer, more sustainable, and fairer future for the Brazilian energy sector.
