The THEMIS solar power tower is a research and development centre focused on solar energy. It is located near the village of Targassonne, in the department of Pyrénées-Orientales, south of France, 3 kilometres from the world's largest solar furnace in Odeillo.
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.
Research and development is focused on solar energy, and THEMIS is a research facility as well as a photovoltaic power facility and a solar thermal energy plant.
