The Ashalim power station
The Negev travel guideThe Ashalim power station is a solar power station in the Negev desert near the kibbutz of Ashalim, south of the district city of Be’er Sheva in Israel. It consists of three plots with three different technologies the station combines 3 kinds of energy: solar thermal energy, photovoltaic energy, and natural gas.
In the 1950’s, David Ben-Gurion spoke about his vision for “exploiting the abundant solar energy in our country and especially in the Negev”. Six decades later, drivers to Eilat are witnessing a remarkable shiny site, a thermo-solar power station in Ashlim in the Negev. The uniqueness of the station, whose construction began in 2015, is the production of electricity from energy produced from the radiation of the sun’s rays using half a million mirrors during the day. The mirrors are installed on steel constructions which are fixed to the ground, heating thermal oil inside insulated tubes to a temperature of 400 degrees Celsius. A system of heat exchangers heats water which creates steam that runs a huge turbine. A generator is connected to the turbine that supplies electricity.
Another effect of this station is the ability to store solar energy during the day, which is released during the night and produces additional electricity for about 5 hours and all this as mentioned without direct sunlight. The storage of the additional energy is made possible by means of two large steel tanks (made of steel with a lower wall thickness of about 63 mm and weighing 1,070 tons each), which store inside a special chemical salt that heats up during the day and heats the oil during the night.
The project covers an area of about 400 Hectares, and is expected to supply electricity to about 60,000 households. This amount of electricity is equivalent to 1% of the total national consumption.
The supply of the station is 121 MWh and the annual output is about 450 GWh.
15% of the energy produced at the station is utilized from natural gas that will be transported through pipes laid by the Negev Gas company to the entrance of the station.
