The two-unit, US$900 million Andina-Hornitos plant, which supplies power primarily to the Esperanza and Gaby mines in Chile's II Region, began operating in 2011-2012.[1][2]

In mid-2017, plant owner Engie enlisted Citibank's help in seeking a buyer for the Andina-Hornitos plant, in accordance with the company's move to a more renewable energy portfolio.[3]


The plants' proximity to the community of Mejillones has made them highly controversial, prompting fears of rising cancer rates and provoking public protests.[4][5]

Planned Phase-out

In February 2018 Chilean president Michelle Bachelet announced that Chile will phase out coal-fired plants,[6] and Engie announced that it will close its coal-fired plants in Chile, Andina-Hornitos among them.[7] Engie had previously announced that it would try to sell the plants to new operators instead of closing them.[7] In June 2019, Chilean president Sebastián Piñera released a plan drafted by the Chilean Ministry of Energy detailing the decommissioning schedule for all Chilean coal-fired plants. According to the plan, Andina-Hornitos power station will cease operations no later than 2040, and plant owner Engie agrees to consult with the government every five years to renew details of the plan, subject to management and shareholder approval, Engie's legal obligations to meet environmental targets and supply contracted levels of power, and other criteria.[8]
