Concrete pumping under floodlights was the latest milestone moment in the construction of Mainstream’s 571 MW Condor portfolio of renewable energy projects in Chile.
A civil works crew with contractor Sacyr worked into the night to complete the first of 35 turbine bases at the site of our Tchamma Wind Farm.
The reinforced structure, which took 11 hours to pour, will eventually support a 454-tonne tower that soars 90 metres over this northern desert region of Antofagasta.
When fully operational in 2021, Tchamma will generate 157.5 MW of clean energy at capacity, enough to power 186,937 Chilean homes while saving 177,996 tonnes of CO2 emissions a year.
The project is currently being built out alongside two other wind farms – at nearby Cerro Tigre and Alena, in the southern Biobío region – as well as the Río Escondido solar PV plant in Atacama.
Together they form the first phase of Mainstream’s wholly owned and fully contracted 1.3 GW Andes Renovables platform, which is set to play an important role in Chile’s green recovery from the COVID-19 pandemic.
In April, the country became the first in Latin America to propose new CO2 cuts to meet the climate action goals of the Paris Agreement, pledging to peak CO2 emissions in 2025 and achieve carbon neutrality by 2050.
Tchamma Wind Farm
Tchamma is a 157 MW wind farm project located in Calama, Antofagasta Region, in Northern Chile.
Tchamma wind farm is included in the Cóndor portfolio of projects within the 1.3 GW Andes Renovables Platform. The project consists of 35 turbines and connects to the Pallata substation via a 37 km long transmission line.
The project consists of 35 (4.5 MW) turbines and reached commercial operations date in 2021.
