Four potential bidders have bought the tender documents for the engineering, procurement and construction project from the client.

The companies are South Korea’s Hanwha Engineering & Construction with the local Arabian Bemco Contracting Company; Japan’s Mitsubishi Heavy Industries; Marubeni Corporation, also of Japan; and China’s Sepco 3 Electric Power Construction Corporation.

SEC had originally planned to tender the project as a 1,200MW main package with a second optional 1,200MW package. Now the utility is asking for one bid for a plant with capacity of 2,200-2,640MW.

The original bid deadline was extended from May.
