 In 2004, a rehabilitation program was devised by the General Council of the Pyrénées-Orientales, to produce power, and create a research and development centre on solar energy with the Centre national de la recherche scientifique (CNRS), and Tecsol, a local engineering office.THEMIS still has its 201 sun-following devices called heliostats, most of them still equipped with mirrors (53.70 m² each) covering an area of 11,800 m² in total, able to send the solar energy towards the hot spot at the top of the 104 m central tower, where the receiver was originally placed (which is now part of the exhibition outside the Odeillo solar furnace).The heliostats are, however, no longer operational.
