Yamama Cement Company

Reference case

Efficient and reliable solution for harsh operating conditions

Located in the Saudi Arabian capital, Riyadh, Yamama Cement Company is regarded as the oldest cement company in the central region of Saudi Arabia and one the largest in the entire kingdom.

When Saudi Arabia announced the Saudi 2030 Vision in 2016, Yamama Cement Company turned to Wärtsilä for a solution that would be in accordance with the vision's regulations requiring more efficient power usage. As Yamama Cement Company started negotiations with Wärtsilä in 2014, it compared the viability of using gas turbines with Wärtsiläs internal combustion engine (ICE) technology – ultimately favouring ICE.

Increased efficiency with waste heat recovery system

Under an engineering, procurement & construction (EPC) contract, Wärtsilä delivered a 161 MW FlexicycleTM power plant featuring 10 Wärtsilä 18V50DF dual fuel engines with one redundant engine (N+1 configuration). With the solution, Yamama can use excess exhaust heat to generate even more electricity. Additionally, the company ordered two more engines in 2023, making the plant's output 198 MW.

The dual-fuel power plant operates primarily on natural gas with light fuel oil and crude oil as backup fuels. The plant will provide power to run the Yamama facility, contributing significant energy generation for Saudi Arabia's cement sector.

As a full EPC project, Wärtsilä was responsible for handling all aspects of the construction and delivery of the plant. A 5-year Operation & Maintenance (O&M) agreement with a 10-year spare parts supply agreement was signed to cover every aspect of the day-to-day operation and all related maintenance and administration tasks.

Meeting customer needs

Yamama Cement is Wärtsilä's first gas-fired Flexicycle power plant in Saudi Arabia, and it has been a continuation of Wärtsilä's successful record in the country. The plant is a landmark power plant in Saudi Arabia because of its combined cycle and dual-fuel capabilities, and it is Saudi Arabia's largest-to-date engine plant installation. The project was achieved through Wärtsilä's emphasis on customer centricity - Where customer interests and satisfaction come first.

The operating conditions in Saudi Arabia's desert climate are harsh, making efficient power usage more difficult. The environment presents its own challenges, with high ambient temperatures, dust and scarce water resources. Usually, cement plants are located in remote areas, and most of the cement industry in Saudi Arabia is powered by captive power plants like Yamama Cement.

While the plant's ability to operate with light fuel oil and crude oil as a backup is nothing new, its real benefit lies in the waste heat recovery system that will use excess heat from the exhaust to power a steam turbine and generate electricity, maximising the plant's efficiency. The solution combines excellent efficiency with complete reliability and availability, providing a great return on investment. Wärtsilä's offer complied with all of the customer prerequisites – technically, economically and operationally.
