The company has already begun construction works for the solar project, which is located in Las Vaguadas.
It expects to start installing around 20,000 bifacial solar panels at the 21ha site over the coming weeks.
The solar project’s development comes after RWE began the construction of two solar projects, Casa Valdes and Puerta del Sol, in Guadalajara province last year.
Each of these two solar farms will have 44MWac of capacity.
RWE Renewables Iberia president and CEO Robert Navarro said: “We are happy to contribute to the energy transition in Spain with our three new solar farms under construction.
“In total, we will install more than 210,000 solar modules.
“Once completed, these projects will make a substantial contribution to reach the local climate targets and will add around 100MW (of) solar capacity to our already strong renewables footprint in Spain.”
Work on the three solar power projects is expected to be completed in the first quarter of next year.
Once operational, the solar farms will generate enough electricity to power around 68,000 households in the region.
RWE currently has more than 44MW of operational wind power capacity in Spain.
The company is also involved in developing the Andasol III solar thermal power station, as well as a solar power plant in the Spanish province of Toledo.
RWE’s 45MW Alarcos ground-mounted solar project in Ciudad Real, Spain, began operations in 2020.
In addition, the company is involved in the DemoSATH floating wind power project, which is scheduled to begin operations later this year.
In July this year, RWE opened the 96MW Clocaenog Forest onshore wind farm in North Wales.
The wind farm is equipped with 27 wind turbines and has the capacity to power 63,800 UK homes with clean energy.
