Colbun Powers Polpaico's Cerro Blanco Solar Farm

• Colbun and Polpaico Soluciones are constructing the largest self-consumption solar plant in Chile, equipped with 15,000 bifacial solar modules and trackers. The 9.9-MWp project will generate 21.5 GWh of electricity annually from 2024. Efizity is building and operating the solar farm, to complement their 2018 renewable power agreement.

Colbun and Polpaico Soluciones have announced the construction of a 9.9-MWp captive solar photovoltaic plant at the Cerro Blanco cement factory in Chile's Santiago Metropolitan Region. This is the largest solar self-consumption project in the country, with 15,000 bifacial solar modules mounted on trackers for optimal power generation. Colbun Soluciones by Efizity is building and operating the solar farm, which is expected to start operation in 2024 and generate 21.5 GWh of electricity annually. The project complements an existing agreement signed in 2018, which secured renewable power for Polpaico from Colbun.

What Is the Largest Solar Self-Consumption Project in Chile?

• The project is expected to reduce the electricity costs of the Cerro Blanco cement factory by over 10%, resulting in lower costs for the production of cement and other products.
• It is being carried out in partnership with a renewable energy company, Efizity, which is a subsidiary of Chilean energy giant Colbun.
• The project includes the construction of 15,000 bifacial modules with trackers, as well as the installation of a 22/110 kV substation, cabling and infrastructure works.
• The project is estimated to save over 50,000 tons of CO2 emissions per year and will be the largest solar self-consumption project in Chile.
• The project will also create jobs in the local area and will serve as a model for other energy projects in the country.
• The Cerro Blanco solar farm will be the first of its kind in Chile and will provide a new source of energy for the region.
