Egyptian President Abdel Fattah al-Sisi has inaugurated two of three mega power plants in Egypt built by Orascom and Siemens.
The New Capital and Burullus combined cycle power plants were inaugurated by al-Sisi.
The power plants have a total power generation capacity of 9,600 MW.
"The execution schedule for both projects was extremely challenging particularly at Burullus, which was the first project out of the three mega power plants to finish despite the latest start and the most difficult site conditions," said Egyptian construction giant Orascom in a press statement.
The Burullus remote site had to undergo a great deal of "complex geotechnical engineering", Orascom added.
More soil improvement and piling work than had been in initially expected had to be carried out as well, in addition to immense marine and water intake structures in the open sea.
In the last 36 months, Orascom Construction has added 12,500 MW of energy to Egypt's national grid, boosting the company's reputation as a key contractor in the Middle East's power market.
