German company Encavis is to supply electricity from the 300MW Talayuela solar farm in Spain to an unnamed international energy company under a 10-year power purchase agreement (PPA).
The total volume of electricity agreed over the period of the PPA is 4300 gigawatt-hours, Encavis said.
Talayuela is also being developed by Solarcentury, which has a 20% investment in the project.
The plant is scheduled to be connected to the grid towards the end of the third quarter of 2020.
Encavis expects Talayuela to generate annual sales of around €25m from the first full year of operation.
Encavis chief executive Dierk Paskert said: “The first long-term power purchase agreement signed for a solar park without any support from feed-in tariffs is a milestone for Encavis with a clear signal effect for further contracts of this kind and supports our consistent growth strategy in this market segment
“The conclusion of this PPA and the launch of this park next year will take Encavis to a new level, just as it will stimulate the market for comparable contracts in many countries.”
