Colbún Launched the Tenth Winter Campaign for Its Angostura Power Plant

Colbún marks 10 years of its awareness campaign about the Angostura plant (Santa Bárbara and Quilaco, running since 2014). As a run-of-river plant with no reservoir, it opens its gates when flow exceeds 700 m³/s — a normal, planned winter operation, not an emergency. It coordinates with DMC, DGA and SENAPRED, informs 70+ stakeholders, and works with local communities to ease concerns.

Colbún Reports EBITDA of US$156.9 Million for the Second Quarter of 2026

Colbún S.A. reported 2Q26 EBITDA of US$156.9 million, up 12% from US$140.6 million a year earlier, despite rainfall deficits of up to 89% versus an average hydrological year. Generation rose 19% on the return of the Santa María plant, higher output from the Horizonte wind farm and greater dispatch at the Nehuenco gas complex, shifting the company from a net buyer to a net seller in the spot market. Revenue climbed 12% to US$449.2 million. Profit for the quarter, however, fell 24% to US$36.6 million, hit by non-recurring items — chiefly the early cancellation of coal contracts signed in 2022 — and higher financial expenses. For the first half, EBITDA was US$289.5 million (−9%) and net profit US$60.9 million, down from US$130.6 million, largely due to the TGP gas pipeline outage in March that forced Fenix onto diesel. Highlights: 68 new energy contracts in Chile (481 GWh/year), 8 in Peru (15.5 MW), and BESS Celda Solar at 94% progress with BESS Diego de Almagro Sur at 58%.
