EDA Renováveis has contracted Exergy for the revitalization of the 5-MW Ribeira Grande geothermal power plant in São Miguel in the Azores Islands.
EDA Renováveis, S.A., part of the EDA Group, has announced that it has signed a contract with Exergy International (Exergy) for the revitalization project of the Ribeira Grande geothermal power plant in the island of São Miguel in the Azores archipelago.
The contract is valued at EUR 24.5 million and will involve the design, construction, supply, assembly, testing, and commissioning of a new 5-MW generator set. This will replace the existing 2 x 2.5 MW units that have been in operation since 1994.
The contract also represents the return of Exergy to the Azores Islands, as the same company worked on the 4-MW Pico Alto geothermal power plant which went into operations back in 2017.
The project to rehabilitate the Ribeira Grande power plant is part of the wider effort of EDA Renováveis to expand renewable energy capacity in the Azores, including geothermal, wind, solar, and hydropower. The main focus is on geothermal using EU funding through the Recover and Resilience Plan. Part of this initiative is the capacity expansion of the Pico Vermelho geothermal power plant, adding 12 MW of new capacity.
