Context of the project
At the request of Rwanda Mountain Tea (RMT) and with the financial support of BIO Invest (Belgian Investment Company for Developing Countries), SHER Ingénieurs Conseils has carried out the final design and drafted the tender documents (DAO) for the Giciye hydropower station. SHER was also commissioned to monitor and control the works. The project is located in the Western Province of Rwanda. The diversion weir is located on the Giciye river. The water is then conveyed to a surge chamber via a 2.5 km concrete canal with a flow rate of 4m³/s. A 350 m long penstock then feeds a hydroelectric power station located 130 m below and equipped with 2 PELTON turbines, each rated at 2 MW. The plant is designed to produce around 18.3 GWh per year. Production is fed into the EUCL network, the Rwandan electricity distribution operator.

- Drawing up the final project
- Preparing the tender documents and defining the technical specifications for the equipment
- Consulting companies and suppliers
