Siemens will supply the key components for the Attarat steam power plant in Jordan. The customer China Energy Engineering Group Guangdong Power Engineering Co. Ltd. will build the facility as general contractor for the operator of the plant, the Attarat Power Company. Siemens’ scope of supply comprises two SST5-5000 steam turbines, two air-cooled SGen5-1200A generators, and the turbine control system. The condenser is air cooled to address the lack of water at the site. This can be seen as a global trend for dry areas where water is mainly used for households, farming and ecosystem. The power plant will start operation in mid-2020 and will feed up to 470 MW to Jordan’s power grid.

The Attarat facility will supply enough electricity to cover up to 15 percent of the country’s annual power demand. Jordan is one of the most water-scarce countries in the world. The air cooled condensers will save up to 90 percent of the water needed for the plant’s operation compared with the use of a wet cooling system. Siemens will supply low-pressure turbines which are able to withstand the high back pressure caused by the condensers. The SST5-5000 is the most compact steam turbine generator consisting of one combined high- / intermediate pressure and one low pressure module ever built for a steam power plant. This will provide a small footprint and highest possible performance.

 

Jordan is considered one of the driest countries in the world, and 14 percent of the country’s power capacity is used for water treatment and distribution. The power plant will be built in the desert at Attarat Um Ghudran, 100 kilometers southeast of the Jordanian capital Amman and away from the country’s natural water supplies. The efficient use of scarce resources, especially water, is a critical challenge to provide a reliable power supply for the local population and economy.

Siemens has received two orders from Russia and Turkey for a model SST-111 compact steam turbine. One turbine was ordered by the Russian aluminum producer Rusal for a production facility in Volgograd and is to be delivered at the end of April 2017. The other turbine is to be supplied to the Mimsan boiler manufacturer in Turkey. This turbine is to be used in a biomass plant of the owner Oltan Köleoglu Energy in the Turkish city of Mecitözü, a good 250 kilometers east of Ankara. This SST-111 turbine is scheduled to take up operation in the summer of 2017.

The SST-111 for the Russian project was ordered by Rusal. The French company Fives Solios SA is building a plant for Rusal in Volgograd which will manufacture anodes for the production of aluminum starting next year. The waste heat from the plant will be utilized by the SST-111 turbine to generate around 8 MW of electricity for power supply to the production facilities. Anodes and cathodes are used for applying electricity to the source material bauxite to liquefy it for the production of aluminum. Also included in the scope of supply is a generator, a condenser, an exhaust steam line and a reducing station. A similar reference plant is already in operation in Gomel in Belarus.

 

The second turbine is to be used in a biomass power plant of the end customer Oltan Köleoglu Energy. The plant is fueled primarily with hazelnut shells for generating electricity. The Turkish Black Sea region produces three quarters of the world’s hazelnut supply. The scope of supply for this order also includes site erection and on-site commissioning.

Designed to operate with five MAN 18V48/60 engines and a MAN MARC® steam turbine, the new power plant has a production capacity of up to 96 MW. It is the second plant in Africa to make use of MAN’s diesel combined cycle product package. The waste heat from the engines powers a steam turbine, which in turn generates 6.6 MW of electricity.

The power plant, which is located in Tobène in the region of Thiès, 90 km north of Dakar, will supply to the national grid that is operated by Senegal’s national electricity company, SENELEC. It will generate the equivalent of 15 percent of the country’s current electricity consumption. This electricity will be used to power businesses, shops, universities and houses, thus providing a whole host of new opportunities for growth within Senegal, which currently experiences recurring power outages.

“The new plant uses our diesel combined cycle product package, which offers outstanding performance and excellent environmental standards. Thanks to the second cycle using a MARC® steam turbine, fuel consumption is lowered by 6 percent and CO2 emissions are also reduced for any kWh produced,” says Mesut Yentur, CEO of MAN Diesel & Turbo France and Head of Power Plant Sales in the French-speaking regions of Western Africa.MAN-1

Thanks to its effective partnership with MATELEC, a Lebanese company specialising in electricity infrastructures, MAN has managed to get the plant commissioned in record time. “We are very happy with this project,” says Sami Soughayar, CEO of MATELEC. “Our collaboration with MAN Diesel & Turbo proved to be highly professional and a great success. With project teams being perfectly coordinated, it only took just over 15 months for the power plant to be able to deliver its first MW to the Senegalese national grid.”

With the existing plant having now been taken over by MAN PrimeServ, MAN Diesel & Turbo’s service brand, to ensure best-in-class maintenance is provided, an expansion is already planned.

By adding a diesel engine, the plant’s generation capacity will be increased from 96 MW to 115 MW by the end of the second working phase.

MAN Diesel & Turbo is witnessing a rise in its activities in Africa. Having had a presence in South Africa since 2008 and in Dakar since 2010, the company opened a new Sales & Service office in Lagos, Nigeria in 2015 and is currently building plants in Gambia, Eritrea, Niger and Burkina Faso. These successes are based on more than 50 years of doing business in Africa. During that time, over 3.2 GW of generation capacity have been installed in 37 African countries.
