First Siemens H-class turbine for the GCC

24 December 2018

Siemens has signed a contract to build what is expected to be the most efficient power plant in the United Arab Emirates, bringing the company’s H-class turbine to the Gulf Co-operation Council (GCC) for the first time. Signed by Siemens, Dubal Holding and Mubadala Investment Company, the agreement will see the development of a high efficiency combined cycle power plant at Emirates Global Aluminum¹s smelter in Jebel Ali, Dubai.

The 600 MW+ plant will boost the efficiency of power production at the smelter, reducing emissions and the consumption of natural gas.

"The choice of H-class technology for the EGA smelter reinforces our strategy that highly-efficient, gas-fired power generation is just as important for industry as it is for powering countries," said Lisa Davis, member of the Managing Board, Siemens AG.

The new power plant is expected to lower greenhouse gas emissions from EGA's power generation at Jebel Ali by some 10 %, by 7% at the Jebel Ali smelter. NOx emissions are expected to be reduced by 58 %.

"This is a significant project for Dubal Holding as we continue to broaden our industrial footprint, working with Mubadala to further develop businesses in power generation," said Abdulnasser Bin Kalban, chief executive officer of Dubal Holding.

Mubadala and Dubal Holding are to establish a joint venture to develop the new power plant at the smelter. EGA intends to buy the facility's output for 25 years following commissioning. EGA is the largest industrial company in the UAE outside the oil and gas sector, and the third largest power producer in the country behind utilities DEWA and ADWEA.

The H-class gas turbine from Siemens can boast of benefits such as high efficiency, short start-up times and fast response to load changes. In combined cycle operation, the output of the 50 Hz version is more than 665 MW under ISO condition and net generating efficiency 61 %. Siemens has now sold 90 H-class gas turbines worldwide, 66 of which have already gone into operation with more than 900 000 fired hours globally,
