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]
