 THEMIS solar power tower, owned by the General Council of the Pyrénées-Orientales, was strategically located in the region of Cerdanya, in the Pyrénées-Orientales, because the conditions are excellent for solar energy.First, Cerdanya has almost 2400 hours of sunshine a year; second, there is a very low wind limiting the time of disruption of the plant; third, the site is at a high elevation providing stronger sunlight.The land chosen for the plant is on a slope between 6° and 18°, which is suitable for a power tower.
