Our Investments

Shuaibah Water and Electricity Company

The Shuaibah IWPP facility is owned by the Shuaibah Water and Electricity Co. (SWEC) with ACWA Power being its major share holder. This IWPP project was the first transaction of the Water and Electricity Company (WEC) and is worth $2.45 billion. Shuaibah IWPP is one of the largest combined power and water plants in the world. Arabian Heavy Crude Oil is used to produce steam for power generation and desalinated water production using multi stage flash (MSF) technology.

The complex comprises three combined water and power groups, each with a steam turbine/generator train and four multistage flash water desalination units. Construction started in January 2006 and achieved commercial operation for Group 1 during May 2009. Subsequently, Group 2 and Group 3 achieved their commercial operation in June and July 2009 respectively. The facility is situated 110km south of Jeddah and supplies the cities of Makkah, Jeddah, Taif and Baha with both power and water.

The main shareholders are two Saudi Arabian government entities; the Public Investment Fund and Saudi Electricity Company, and a private consortium comprising ACWA Power, Tenaga Nasional Berhad,Malakoff Berhad and Khazanah Nasional Berhad.

From commercial operation until the end of 2009, the facility dispatched power at an average of 99.5% of the available capacity. Desalinated water was dispatched at 69.4% of the available capacity, primarily due to constraints in the quantities that the off-taker could accept. Safety is of key importance, and in 2009, the project completed 34.7 million man hours of construction and operations without any lost time incidents.
