EDP Renovaveis is to sell electricity to Ammper Energia from the 200MW Los Cuervos solar farm in Mexico under a 15-year power purchase agreement (PPA).
Los Cuervos is expected to start operations at the start of 2021, EDPR said.
The deal means EDPR has now contracted abut 80% of the 7GW targeted global capacity build-out for 2019-2022.
In Mexico, the company will have about 500MW installed capacity in 2021.
EDPR said its portfolio will reach 1.5GW of solar capacity build-out by 2022.
EDPR chief executive Joao Manso Neto said: “We are very pleased with the progress of our PPA strategy with landmarks such as the one we are announcing today.
“We have reached 80% of the ambitious goal of incorporating 7GW into global capacity, which we set out in our business plan, and we still have two years to go.
“Furthermore, we have reinforced our commitment to the Mexican market, where we already have an installed capacity of 200MW, and we continue to boost our role as one of the benchmark renewable energy producers around the world.
“Finally, I would like to make special mention of our commitment to maintaining our investment plan to 2022, despite extraordinary current circumstances.”
