Colombia

Colombia has the third largest installed hydropower capacity in South America with untapped hydro potential up to 14 GW, currently the instaled capacity is ca 11.4 GW. About 900 sites have been identified as having small hydro power with potential installed output of ca 1.8 GW. Driven by increasing demand and an integrated power grid with neighbouring countries, the hydropower sector is continuing to expand.

RENFIN/HYDROPOL Group, through dedicated project companies, intends to expand Colombia’s renewable electricity generation capacity by developing two small hydropower plants (SHPPs) in the Nariño region, close to the city of Pasto.

Projects in development with expected COD 2028

Both projects are run-of-river schemes on the Opongoy River:

Opongoy I (4.5 MW):

will utilize a gross head of 160 m and a design flow of 3.5 m³/s. Annual generation is expected at approx. 25 GWh. The scheme includes a 2.7 km pressurized headrace and a powerhouse equipped with Francis turbines. Power will be evacuated through a new 1.2 km 34 kV line connecting to the local grid.

Opongoy II (13.0 MW):

will utilize a gross head of 290 m and a design flow of 6.0 m³/s. Annual generation is approx. 65 GWh. The project includes a 3.7 km headrace, powerhouse with Francis turbines, and a 300 m 115 kV evacuation line directly connected to the regional transmission grid.

Together, the plants will provide an annual net production of 90 GWh, enough to supply around 40,000 households or equivalent small and medium enterprises.

Electromechanical equipment will be supplied by European manufacturers (Francis turbines, generators, switchgear, automation), while civil works will be undertaken by Colombian contractors to ensure local employment, lower construction costs, and strengthen relations with the community.
