The photovoltaic (PV) field will be "unprecedented" in size for Israel, covering about 6 square kilometers (2.3 square miles) of land near the town of Dimona, the Finance Ministry said.
The project will be handled as a Public Private Partnership, the ministry said, in which a company that wins the tender will fund, build and operate the facility for a pre-determined period, after which it will be handed over to the state at no cost.
Both projects are part of an Israeli push to have 10 percent of its energy production come from renewable sources by 2020.
