Mainstream is also exploring incorporating hybrid solutions as part of the platform, such as storage systems with large-scale batteries located at the various assets.
This will allow them to generate power for more hours in a day, providing additional flexibility to better serve customers’ needs and providing additional support to the grid.
This would build on Mainstream’s history of realising and commercialising emerging technologies, which includes the recent agreement to explore the development of green hydrogen and low-cost ammonia production in Chile.
The Humboldt portfolio will supply a recently-signed, long-term bilateral private Power Purchase Agreement (PPA) with a strategic partner.
This is the second such deal within a month for Mainstream in Chile, following the signing of a PPA to supply power from the Copihue phase of the Andes Renovables platform.
Mary Quaney, Mainstream’s Chief Executive Officer, 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."
