The first wind turbines are being erected and the installation of solar panels has begun at Enefit Green's hybrid park in Purtse, Estonia.
Five wind turbines with a total capacity of 21MW will be erected in at the site.
A solar park with 49,000 panels and a total capacity of 32MW will also be built in the same area.
Both developments use the same equipment, substation, connection and connection capacity to bring the electricity produced from wind and solar to consumers.
Since from autumn to spring is the best time for wind power production and from spring to autumn for solar power production, the electricity output of a hybrid plant is more consistent throughout the year and the network is better utilised said Enfit Green.
Janek Lillemägi, senior project manager at Enefit Green said: "If strong winds don’t interfere with the work, a wind turbine can be assembled in two days.
"The lower tower sections have been placed in all positions.
"Now the installation of the upper sections with a higher crane continues, followed by lifting the nacelles to the tops and fixing the blades."
