Alstom Grid has been awarded a contract of approximately 6 million by Light Energia, who controls and distributes part of the power in Rio de Janeiro State in Brazil, to improve and modernize Santo Antônios gas-insulated substation (GIS) in downtown Rio de Janeiro. The project will boost power reliability to better serve Light Energias clients in Rio de Janeiro. Modernizing the equipment will increase the lifespan of the substation by 20 years.

This technical upgrade is part of an overhauling maintenance work. Under this contract, Alstom will implement new technologies to extend the lifecycle of the substation, whilst preserving the environment. The new components will promote, for example, ease detection and identification of SF6 gas leakage. It is composed of new material for sealing gaskets, a BWatch3 digital monitoring system to check conditions online, new safety devices and new fast coupling filling valves to reduce gas emission.

This new project stems from a long-term commitment to support the modernization of Light Energias gas-insulated substations, highlighting their trust in our global expertise and our local teams dedication. We are committed to offering the best services to our clients, and to their final customers, says Sérgio Gomes, Senior Vice President of Alstom Grid in Latin America.

This new contract falls within a large modernization strategy implemented by Light Energia under which Alstom had modernized two gas-insulated substations: Camerino with eleven bays, and Posto 6 with six bays, both located in Rio de Janeiro.
