El Marqués: Green City's first photovoltaic installation in Spain

Toulouse, August 13, 2020 – The last inspection has been carried out and the final acceptance has been completed. After a first test phase, “El Marqués”, Green City’s first solar power plant on Spanish soil is now in full operation and has already achieved a first positive assessment with a green electricity production of 9.5 GWh. The project represents Green City’s first photovoltaic system without feed-in tariffs. A long-term power purchase agreement (PPA) has been concluded for this purpose with the Swiss group Alpiq.

After a construction period of only 9 months, Green City AG connected its first solar park in Spain, “El Marqués”, to the grid in March of this year. The factory is located in the northeast of the country, near Zaragoza. In cooperation with local partners, an ideal environment for the solar project was created in a very short time on an area of 18 hectares: In total, 30,464 modules have been installed and are expected to produce around 20 million kilowatt hours of green electricity per year, for a capacity of 12.3 MW. 365 trackers allow the modules to be aligned with the position of the sun from morning to evening in order to maximize electricity production. The Tracker Control program optimizes the path of each tracker to minimize shade between PV modules when the sun is low, early in the morning and late in the evening, and to prevent production losses.

During the first months of the test operation, 9.5 GWh were produced. Due to the transnational restrictions caused by the coronavirus pandemic, the start up was a particular challenge and today Green City celebrates the successful entry into the international photovoltaic market.



Jens Mühlhaus, spokesperson for Green City’s board of directors, sees this as an important step into the future: “Solar energy is becoming the most cost-effective energy source in Europe. As Green City, we are proud that with this power plant in Spain, despite the coronavirus, we have already achieved a clearly good result in the production of electricity in a very short time. The Spanish market offers a lot of potential for other projects of this type and we look forward to future developments with confidence ”.

Thanks to the good cooperation with local partners, the project could be implemented quickly. For Green City, this is the first cooperation with the Spanish construction company IASOL, which is considered as the main promoter and installer in Aragon in the development of clean energy and the construction of photovoltaic power plants.

“El Marqués” is the first PV plant by Green City to be connected to the grid without a feed-in tariff. Last fall, after its successful market entry, Green City AG entered into a long-term power purchase agreement (PPA) with the Swiss group Alpiq for “El Marqués”.
