The efficient use of fossil fuels is paramount to maintaining a stable power network in the U.S. Siemens provides highly efficient gas turbines, combined-cycle power plants (CCPP), combined heat and power (CHP) plants as well as integrated gasification combined-cycle (IGCC) plants.
Highly efficient gas turbines
Due to the demand for greater operating flexibility, energy efficiency and a reduction in CO2 emissions in power generation, the demand for gas-fired power plants is increasing at a rapid pace. With a comprehensive gas turbine portfolio, Siemens is optimally positioned for this market development. Siemens’ innovative 375-megawatt H-Class gas turbine is the most efficient and powerful gas turbine in the world, able to achieve efficiency levels of over 60%.
These innovative machines for power generation are also used in the United States. The Florida Power & Light Company (FPL) has commissioned Siemens to supply three H-Class gas turbines to modernize its Port Everglades Next Generation Clean Energy Center, scheduled to start operation in 2016. Using Siemens’ latest gas turbine technology, the modernized power plant is expected to generate power using a third less fuel per megawatt-hour, compared with the existing facility. During its 30-year operational life, the new plant is expected to produce more than USD 400 million in net savings for FPL customers.
Combined-cycle power plants
Siemens has also been awarded an order for the turnkey supply of the Panda Temple II power plant in Temple, Texas. Siemens will supply the natural-gas-fired combined-cycle power plant, partnering with Bechtel. The power plant, with a capacity of 758 megawatts, will be among the cleanest fossil-fueled power plants in the U.S. When it starts operation in 2015, it will supply the power needs of approximately 750,000 homes in the Central Texas area.
Siemens Flex-Plant technology for efficient power generation
In summer 2012, the Lodi Energy Center, with an installed capacity of 300 megawatts was officially inaugurated. For this natural gas-fired plant, Siemens supplied the SCC6-5000F 1×1 Flex-Plant power island, which allows for the seamless integration of renewable energy and traditional fossil fuels. With an efficiency of over 57 percent, and low startup emissions, the LEC will be one of the cleanest fossil power plants in the U.S.
In El Segundo, Siemens installed California’s second Flex-Plant for the U.S. utility NRG Energy. As with the Lodi Energy Center, the project offers an environmentally-friendly solution that has extremely short startup times and is low on startup emissions and water usage. The Flex-Plants have a total installed capacity of 550 megawatts, and have the potential to supply 450,000 Californian households with power.
Services to improve the energy efficiency of power plants
Siemens offers a range of modernization measures to help older power plants operate more profitably and efficiently. This ranges from modernizing the entire plant to implementing a new operating concept, or simply replacing individual components.
