Helexia, a subsidiary of Voltalia, signs a new contract to supply Telefonica with solar electricity in Brazil

Helexia, a distributed-generation and energy-efficiency specialist, has won an additional 27 megawatts of photovoltaic capacity for the Vivo cell phone network, a Telefonica brand. Helexia is a subsidiary of Voltalia (ISIN code Euronext Paris: FR0011995588), an international player in renewable energies.

Following the August 31 launch of the construction of 17 solar photovoltaic (PV) units to power the facilities of Vivo, a subsidiary of the Telefonica Group in Brazil, Helexia is adding 8 units totalling 27 megawatts to this 20-year contract. Initially planned for 60 megawatts, the capacity is therefore increased to 87 megawatts, turning Helexia as leading Solar PV supplier of Distributed Energy Ressources (DER) to Telefonica in Brazil.

The additional units will be located in the states of Amazonas, Tocantins, Sao Paulo and Rio Grande do Sul. Commercial operation is expected to start in the second half of 2022

With this new contract, Telefonica, an international leader in the telecommunications market, is making further progress in the roadmap of its sustainable development strategy in Brazil, by strengthening its demand for green electricity. Helexia's expertise as a specialist in decentralized solar production units combined with Voltalia's knowledge of the Brazilian market are crowned by the renewed confidence from this partner.

"Telefonica has once again placed its trust in Helexia. We are proud to demonstrate once again the group´s know-how in providing energy services, as well as the synergies between Voltalia and Helexia", said Sébastien Clerc, CEO of Voltalia.
