The Ashalim Plot B (Megalim) hosts a
solar power tower
A solar power tower, also known as 'central tower' power plant or 'heliostat' power plant, is a type of solar furnace using a tower to receive focused sunlight. It uses an array of flat, movable mirrors (called heliostats) to focus the sun's ra ...
. It has an installed capacity of 121 megawatts, concentrating 50,600 computer-controlled heliostats enough to power 120,000 homes. Electricity production commenced in September 2019,
producing 320 GWhr of energy per year. The project was a joint venture between
Brightsource and
Alstom
Alstom SA () is a French multinational rolling stock manufacturer which operates worldwide in rail transport markets. It is active in the fields of passenger transportation, signaling, and locomotives, producing high-speed, suburban, regional ...
. The station was the tallest solar power tower in the world at a height of 260 meters including the boiler
but was recently surpassed by the 262.44 meter tall solar power tower at the
Mohammed bin Rashid Al Maktoum Solar Park.
Ashalim Plot C is a 30 MW photovoltaic plant, commissioned in 2018, one year before the CSP plants.
In 2019
EDF Renewables won a tender for another NIS 150 ($43) million PV plant at a record low price of 8.68 agorot (3 cents) per kilowatt hour.
Reasons for building the power station
According to a press release of the
National Infrastructure Minister of Israel, the establishment has several motivations:
# Economic motivation: reducing imports thus balancing the trade and releasing foreign currency.
# Political motivation: reducing strategic dependence on foreign energy sources.
# Environmental motivation: reducing contamination levels.
# Scientific motivation: pushing forward local technology and science, adapting new technologies from abroad.

project in Ashalim was announced in 2008 and awarded in a competitive auction 2012 at NIS0.79 ($0.22) per kilowatt hour for Plot B – almost a factor of 9 compared to the PV stations tendered in 2019 at the same spot (see above). Similarly, the project on Plot A at NIS 0.76 per kWh, but including 4.5 hours of molten salt storage, delivers four times more expensive power than the results of tenders for solar plus 4 hours of storage awarded at the beginning of 2021 at NIS0.17/kWh ($0.054) to be delivered by 2023.
