{{#badges:CoalSwarm|Navbar-Chilecoal}} The Cochrane power station is a 531-megawatt (MW) plant in Mejillones in Chile’s northern region, Antofagasta, Region II. It was jointly developed by Chile's AES Gener (60% share), and Mitsubishi (40%), at a total cost of US $1.3 billion.

The project received environmental approval in September 2009.[1] A consortium of Japanese and Korean financial institutions has guaranteed up to US$1 billion in funding.[2]

Construction of the plant began in April 2013.[3] According to AES Gener's website, the Cochrane plant is being constructed adjacent to AES Gener's Angamos power station to take advantage of existing port and coal stockpiling facilities.[4]

The power generated by Cochrane's two coal-fired units will supply copper mines in Chile, with commercial operations expected to start in 2016.[5] In October 2014, at a press conference covered by the trade publication Electricidad, AES Gener's Vice President of Engineering Luis Knaak said that the first unit would be completed by May 2016 and the second by October 2016.[6] A report from Chile's Corporación de Bienes de Capital (CBC) stated that construction on the Cochrane plant was 48% complete as of 2015.[7]

The power station was fully commissioned in October 2016.[8]
