CH Vara Blanca is a small hydroelectric scheme located in the province of Heredia, Costa Rica, near the town with the same project’s name. This project was developed by Suerkata S.R.L. a local company with a 20-year experience in the private power production market.
The project uses a maximum of 2200 litre per second from the San Rafael River, which is then transported through a penstock of nearly 2km with a 135m net head, to the Gilkes electro-mechanical equipment package at the powerhouse.
For this project Glkes worked with Ingeteam and Indar.
The highest standards were a requirement of the developer for all aspects of the project including construction, equipment supply and ongoing operational technology to monitor the schemes electrical generation.
