On 26 July 2017, the third renewable energy auction took place in which more than 5,037 MW were awarded at the maximum discount (at no cost to the electricity consumer).
Of the total power, 3,909 MW (77.6%) were for photovoltaic technology, of which Alter Enersun was awarded 50 MW.
With this project, Alter Enersun would have 150 MW in photovoltaic installations by 2020 between Spain, Portugal and Mexico.
