Hydroplant Modernisation Boosts Output

The Takamaka hydroelectric plant, located in a tropical valley within Reunion’s national park, is undergoing a crucial modernisation. This plant is the primary source of renewable energy on the island, currently meeting the energy demands of approximately 35,000 homes. The modernisation will increase the plant's power output and secure the energy network, ensuring a consistent energy supply amidst the intermittent availability of other renewable energy sources.

Two-phase Upgrade Plan

The project is divided into two key phases. The first phase focuses on civil engineering work to extend the building, while the second phase, spearheaded by Omexom Montélimar, involves the installation of two high-voltage cells at the building level. Omexom's responsibilities also include securing the long-term functionality of the plant's discharge facility, considering both plant security and employee safety. Given these requirements, the project has a strict completion deadline to minimize disruptions to Reunion Island’s electricity distribution grid.

Logistical Challenges and Expertise

The project faces significant logistical challenges due to the unique site conditions. According to project manager Christophe Valla, transporting equipment to the upper platform and work zone, which are more than 600 meters apart, is particularly arduous. Equipment must be brought in on rails, a method that is time-consuming and prone to potential breakdowns. This scenario underscores the necessity for expert management of complex projects, an area in which Omexom excels. Two other VINCI Energies business units, Fournié Grospaud Synerys and Actemium Réunion, are involved as partners, supplying command & control equipment and cells respectively.

Construction Timeline and Goals

Construction is scheduled to begin in the second half of 2023, with commissioning expected by June 2024. This modernization project plays a pivotal role in the island's goal of achieving 100% renewable energy by 2023, illustrating hydroelectric energy's sustainable viability for the territory.
