Utility firm Colbun has begun construction of a 9.9MW captive solar photovoltaic plant for Cementos Polpaico’s Cerro Blanco cement plant in the Santiago Metropolitan Region. Colbun and Polpaico Soluciones hailed it as the largest solar self-consumption project in Chile.
The Cerro Blanco solar farm will occupy 12 hectares in the Tiltil commune. It will consist of 15,000 bifacial solar modules mounted on trackers for optimal power generation, with a production output estimated at approximately 21.5GWh/yr.
Colbun’s energy services unit Colbun Soluciones by Efizity will build and operate the solar farm. The companies expect the self-consumption system to commence operation during the first half of 2024. It will complement Polpaico’s existing supply of renewable power, which it has received from Colbun under a long-term agreement since 2018.
