Two units of the Costa Rican Chucas Hydropower Station built by Sinohydro Bureau 11 Co., Ltd. were integrated with the power grid recently.
The units operate smoothly with load, and the temperature of bearing bush, vibration and swing of various parts meet design requirements.
As the first cooperative project between China and Costa Rica involving hydropower, it is also the first contract secured by POWERCHINA in Latin America through competitive bidding.
The first unit was installed in November 2015, and the installation of the second unit was completed in February 2016. Water-free debugging and acceptance of the two units were completed on May 30, 2016. In September, the impoundment target of the dam was completed.
Situated on Tagus River, 40 kilometers south of Costa Rica’s capital San José, the Chucas Hydropower Station is a water diversion type ground power plant.
The project includes diversion tunnels, intake towers for power generation, civil engineering of the plant and mechanical and electrical equipment installation, and a switch station. The total installed capacity is 2×25 MW.
Now that the two units have been integrated with the power grid, the project team will carry out grid-related electrical testing to complete the full load power generation operation and eliminate defects, ensuring that the project is successfully delivered and put into commercial operation.
