Mainstream Renewable Power States 1 Gigawatt (GW) Hybrid new Renewable Platform in Chile


Reading Time: 3 minutes

Mainstream Renewable Power recently announced its expansion plans for Nazca Renovables – a new, hybrid renewable energy platform with more than 1 Gigawatt (GW) of capacity. This will avoid the emission of more than 1.1 million tonnes of CO2 with the help of clean energy generated by the platform and this is equivalent to every one of Chile’s 18 million people planting a tree.


The platform consists of three solar PV generation assets (six in total including three wind farms). The first of these plants, Humboldt, will provide 255 MW of clean energy via the Tata Inti Solar Farm and the Entre Ríos Wind Farm, and construction is expected to start in mid-2022.

The Humboldt portfolio will supply a recently-signed, long-term bilateral private Power Purchase Agreement (PPA) with a strategic partner. Within the span of a month, this is the second such deal for the company in Chile, followed by the signing of a PPA to supply power from the Copihue phase (Andes Renovables platform).

The new Nazca Renovables platform builds on the strengths of the 1.35 GW Andes Renovables platform. It saw Condor (its first portfolio), begin supplying electricity to the grid. Mainstream expects to provide 20% of electricity required by Chilean as the Andes Renovables portfolio comes online in its entirety, by 2022. Once the platform is fully operational, it will supply power to more than 1.2 million homes which will grow Mainstream’s relevance as a renewable energy provider in the country.

Mainstream’s General Manager for Latin America, Manuel Tagle, said, “The Nazca Renovables platform and its three portfolios make Mainstream an even more influential enabler of Chile’s decarbonisation. The six new projects will help bring investment and employment across the country, consolidating Mainstream’s leadership in one of Latin America’s most advanced markets for renewable energy. We’re very excited by the pace of our developments in Chile and will draw on our significant experience with the Andes Renovables platform to ensure Nazca is a similar success.”

Mainstream is also exploring incorporating hybrid solutions including storage systems with large-scale batteries as part of the platform. This will allow them to generate power for more hours in a day, providing additional flexibility to better serve customers’ needs and giving add on assistance to the grid.

Mainstream’s Chief Executive Officer, Mary Quaney, said, “Not only is this platform a significant expansion for Mainstream globally, but it is a prime example of the new possibilities the company is developing through renewable energy agreements with private clients. Flexibility and reliability are key for such clients – and our exploration of integrating storage and batteries shows how we are adapting to the needs of our customers and the energy transition.”
