You are here  Middle size solar thermal plants  The ALSOLEN
company develops medium power thermodynamic solar power plants
(up to 20 MWe) using the technology of Fresnel mirrors. These
power plants called ALSOLEN use oil as heat-transfer fluid. This
oil is heated at 300°Celsius and transfers its thermal energy to
an Organic Rankine Cycle (ORC), which generates electricity via
a turbine.  The originality of ALSOLEN thermodynamic solar power
plants consists, amongst other points, in a design that
maximizes on site fabrication, in a minimum maintenance, in an
optimized performance and a in long lifetime. ALSOLEN power
plants comprise a thermal storage which is directly integrated
in the thermal fluid loop and uses the technology of the
thermocline. The thermal storage ensures an electricity
distribution that fits the consumption requirements.  The
electricity produced can either be used to power local
households or to power local industry. ALSOLEN plants can also
be connected to the Grid to value its production.
