In a separate announcement, Norway’s Scatec said it had signed a 25-year PPA with Egyptian Electricity Transmission Co. (EETC) for a 1 GW solar and 100 MW/200 MWh battery storage hybrid project in Egypt. “This will be the first hybrid solar and battery project in Egypt,” said Scatec CEO Terje Pilskog.
Earlier this year, state-owned utility Egyptian Electricity Holding Co. held an expressions-of-interest tender for the design, construction and operation of a 8.2 MW solar plant and 2 MW/4MWh battery energy storage system, which would be built at the site of an existing microgrid in western Egypt.
The first project involves a 1 GW solar plant with a 600 MWh BESS in the Benban area. The second project is a 300 MWh BESS at the site of Amea Power’s 500 MW Abydos solar array, which is currently under construction. Both projects are in Egypt’s Aswan governorate.
The latest announcements bring Amea Power’s total renewables capacity in Egypt to 2 GW of solar and 900 MWh of BESS. The company claims to have projects in 20 countries, with a pipeline above 6 GW and 1.6 GW currently in operation and under or near construction.
Amea Power, based in Dubai, is developing two large-scale renewable projects in Egypt after securing two PPAs with Egyptian Electricity Transmission Co. The first project involves a 1 GW solar plant with a 600 MWh BESS in the Benban area.
