Colbún S.A. was established after the split of Endesa Chile (into Endesa Chile and Empresa Eléctrica Colbún Machicura) in 1986 when it was controlled by the state-owned company, CORFO (87.4% share). In 1997, CORFO ceased to control the company after selling 37.5% to “Cominco” – 41.5% (Matte Group) and to Suez-Tractebel -58.5%.

In 2005, Colbún merged with Hidroeléctrica Cenelca S.A. (Matte Group) whereby the Matte Group became the main Company’s stakeholder (49%), while Suez-Tractebel reduced its share (19%) to sell, a year later, a part of its share to the Angelini Group (10%).

As of December 2014, the ownership structure is: Matte Group (49%), Angelini Group (10%), Pension Funds (18%) and others (23%). The company has an installed capacity of 3.852 ME, 48% hydro and 52% thermo.
