El Marques: Green City's first solar power plant without feed-in tariff

The photovoltaic system “El Marques” marks a successful start from Green City in Spain, as it is the first Green City photovoltaic system on Spanish soil and the first PV system to be connected to the grid without feed-in tariff.
“El Marqués” is located in the northeast of the country near Zaragoza and covers an area of 18 ha. In autumn 2019, Green City AG was able to conclude a long-term power purchase agreement (PPA/Power Purchase Agreement) with the Swiss group Of companies Alpiq after the successful market entry.
