At least three consortiums have submitted bids for the contract to develop and operate a cogeneration steam and power plant catering to the Sadara petrochemicals complex in Saudi Arabia.

The planned independent steam and power plant (ISPP) project will have a capacity for 400MW-450MW of combined-cycle electricity generation and 550-700 tonnes an hour of steam.

According to sources, bids were submitted for the contract at the end of August.

The consortium bidders include: 

• Abu Dhabi National Energy Company (Taqa) / Samsung C&T (South Korea)
• Al-Jomaih Energy & Water (Saudi Arabia) / Albawani (Saudi Arabia) / Sepco 3 (China)
• Acwa (Saudi Arabia), Korea Electric Power Corporation (Kepco) / Doosan Enerbility (South Korea)

Sadara Chemical Company (Sadara) is the project client. It is the downstream joint venture of Saudi Aramco and US-headquartered Dow Chemical.

The estimated $500m project includes construction of a power plant, substations, a seawater intake system and associated switchyards and switchgear.

The project will also include gas turbines and a back-pressure steam turbine, as well as facilities for steam production.

In 2024, MEED exclusively reported that Sadara had prequalified potential bidders for the project. It is understood that the request for proposals was issued towards the end of last year.

The first units at the $20bn Sadara petrochemicals complex in Jubail began production in 2016, and the complex became operational in 2017.

The Sadara complex is designed to produce more than 3 million tonnes a year (t/y) of chemicals and performance plastics, including polyurethanes, propylene oxide, propylene glycol, elastomers, polyethylene, glycol ethers and amines.

Construction is also continuing on the Najim cogeneration facility, which will supply the Amiral petrochemicals complex with up to 475MW of power and approximately 452 tonnes an hour of steam.

Previously known as the Amiral cogeneration independent steam and power plant, the project is being developed by a team comprising Abu Dhabi National Energy Company (Taqa) and Japanese power generation company Jera.

South Korean contractor Samsung C&T is the engineering, procurement and construction contractor for the project.
