The Superintendencia de Servicios Públicos reported that reservoirs in the National Interconnected System (SIN) reached 62.8% useful volume due to recent rains. Ituango leads at 98.8%, while Altoanchicaya has the lowest level at 15.5%. The agency highlighted robust contributions in key basins and higher river flows.
The Superintendencia de Servicios Públicos Domiciliarios issued a new report on SIN reservoirs, showing recovery to 62.8% useful volume due to recent precipitations.
Ituango holds the highest level at 98.8% with active spillways, followed by Troneras at 94.8% and Calima at 93.4%. At the other end, Altoanchicaya stands at just 15.5%, Chuza at 27.7%, and Esmeralda at 32.8%.
"Ituango is at 98.8% with active spillways, reflecting high storage levels and robust contributions in the Cauca River basin, which exceeds 100% of its historical average," the Superservicios stated. The Bogotá system lags, with Chuza around 30% and Guavio below 50%.
In flows, Ituango tops at 1,035.5 cubic meters per second, followed by Sogamoso at 426 m³/s. Rivers like San Lorenzo (67.5 m³/s) and Bogotá (51 m³/s) surpass 150% of their historical average. "Higher flow means more water inflow, greater energy generation potential, and should result in lower hydroelectric generation costs," the agency added.
Sector experts warn of the need to speed up reservoir filling amid El Niño pressures, advocating a shift to thermal generators during low-rain periods.
