Tihama – Cogeneration of power & steam for Saudi Aramco

ENGIE has been providing Saudi Aramco with power and steam through Tihama Combined Heat and Power (CHP) project, located in the Eastern Province of Saudi Arabia. CHP is an energy efficient technology that generates electricity and captures the heat that would otherwise be wasted to provide useful thermal energy —such as steam or hot water—that can be used for space heating, cooling, domestic hot water and industrial processes. By capturing and using heat that would otherwise be wasted, and by avoiding distribution losses, CHP can achieve efficiencies of over 80 percent, compared to 50 percent for typical technologies (i.e., conventional electricity generation and an on-site boiler).

Summary

The Tihama Combined Heat & Power project comprises four plants at Ras Tanura, Ju’aymah, Shedgum and Uthmaniyah. All are located in the Eastern Province of Saudi Arabia. Natural gas is supplied by Saudi Aramco and the power and steam generated by the plants are used by Saudi Aramco for its processing plants. The project (1,600 MW and 6.3 millions pound/hr steam) awarded in 2003 and commissioned in 2006, was a landmark project for Saudi Arabia, as it was the first large-scale Independent Power Project (IPP) to be undertaken in the Kingdom by the private sector.
