Efficient power generation is the pathway to a sustainable energy system. Siemens supplies innovative products, services, and global energy market expertise.
Reliable power generation
Siemens offers energy-efficient and reliable solutions for fossil and renewable power generation. Our portfolio includes key technologies such as gas-fired combined-cycle power plants with integrated coal gasification (IGCC). Compared with its competitors, Siemens offers the broadest spectrum of future-ready technologies and, at the same time, will make a decisive contribution to energy-efficient power generation. Due to the demand for ever greater operating flexibility, energy efficiency and CO2 reduction in power generation, the worldwide demand for gas-fired power plants is growing at a breathtaking pace.
With its comprehensive gas turbine portfolio, Siemens is one of the world’s market leaders. Gas turbines and combined-cycle power plants offer high reliability and availability, low investment costs, short construction, installation, and service times, high energy savings and energy efficiency. This results in the advantage of the highest operational readiness and flexibility. Siemens developed the most efficient and powerful gas turbine in the world, the innovative 375-megawatt SGT5 8000H model, in operation in Irsching, Germany. The company’s gas turbines cover generating capacities from 4 to 375 megawatts for both the 50 and 60 Hz markets.
Energy-efficient gas turbines for Nigeria and Tanzania
Siemens received several orders from Nigeria for construction of the Geregu II gas-turbine power plant in Ajaokuta, approximately 200 kilometers south of the capital Abuja. The power plant was completed on schedule in mid-2013. Geregu II is a follow-up project to the Geregu I power plant, which Siemens built back in 2006. The company supplied three SGT5-2000E gas turbines, characterized by high levels of reliability, three SGen5-100A generators, as well as all the electrical systems and the SPPA-T3000 control system. With this project the number of Siemens heavy-duty gas turbines in Nigeria increased to eight. The centrally located power plant is of strategic importance for grid stability and is a key project for power supply in Nigeria, helping the country to meet ever increasing power demands.
In Tanzania, Siemens received an order for the supply of three industrial gas turbines. The customer is the Norwegian company Jacobsen Elektro, which will build a power plant for the state-owned energy provider Tanzania Electric Supply Company Limited (TANESCO). The three SGT-800 gas turbines will be supplied to the Ubungo power plant located in Dar es Salaam, the largest city in Tanzania. Siemens will supply the three turbines with a combined capacity of 100 megawatts. Connection to the grid was established in late 2011. The SGT-800 is one of the most efficient industrial gas turbines on the market today. All emission requirements are below international standards and Siemens can thus provide environmentally friendly and energy-efficient fossil-fueled power generation to Dar es Salaam.
State-of-the-art projects in Morocco and South Africa
The power plant in Tahaddart – 30 kilometers south of Tangiers on the Atlantic coast – is Morocco’s first combined-cycle power plant and the first Siemens turnkey plant in the country. The SPPA-M3000 plant management used in Tahaddart optimizes the technical processes and contributes to achieve a reduction in costs. Tahaddart is the first fossil-fired power plant in Africa to be given an international environmental certification. In Wadeville, South Africa, Siemens upgraded the turbo machinery at its balancing facility. The upgrade includes the replacement of the control system on the high speed balancing machine to a PLC system and the installation of the latest state-of-the-art vibration analyses instruments. The facility, with higher levels of energy efficiency, is one of the most technologically advanced in Africa.
