Cemento Polpaico plans to invest US$42m in a 20MW solar power project, to be installed next to its plant in Tiltil municipality, Chile.

The park will help diversify Chile's energy mix and will supply renewable energy to the central power network SIC, through the Punta Peuco substation, according to the environmental impact declaration.

The company estimates it could start construction works this year.

Polpaico, which is 54 per cent owned by Holcim, is Chile’s second-largest cement producer  with a capacity of 2.5Mta from three plants.
