Mainstream inks solar PPA for 100-MW auction winner in Colombia

Mainstream Renewable Power on Friday announced that it has signed a power purchase agreement (PPA) to deliver solar energy from its 100-MW Andromeda PV project in Colombia.

The Ireland-based pure-player secured the 15-year PPA in a private renewables auction organised by Colombia’s regional power distributor Air-e, which ran the competition to procure 850 GWh per year for its customers.

Air-e expected to get some 300 MW of wind and solar under PPAs via the auction process, but ultimately awarded the contracts to close to 200 MW of solar projects. Mainstream was one of four winners, next to Germany’s ABO Wind AG (ETR:AB9), Spain’s Cox Energy and France’s GreenYellow.

Under its contract, Mainstream is set to deliver 180 GWh per year from the Andromeda solar farm.

The Andromeda project is Mainstream’s first development in Colombia, the company said. The power plant will feature some 195,000 solar panels installed in the town called Toluviejo

The PPA will come into effect from 2024.

Mainstream’s Colombia offices are in Bogota. The company says it has been actively growing its development pipeline of wind and solar projects in the country since 2019.

"We look forward to building on this significant achievement in Colombia and enabling it to decarbonise through the large-scale deployment of renewables -- with hundreds of megawatts already in the pipeline, we are well on our way," Mainstream CEO Mary Quaney said.
