Siemens to present power supply solutions for megacities at the Hanover Fair

Erlangen, Germany, As part of the “Metropolitan Solutions” exhibition in Hall 8 at the Hanover Fair from April 4 to 8, Siemens Energy will present four selected projects providing energy-efficient, ecofriendly power supply solutions for megacities. Siemens will show how a sustainable supply of power can be provided for hundreds of thousands of households in Greater London from an offshore wind farm in the Thames estuary. The company will also provide information on a comprehensive smart grid solution for a utility in Texas. A further example will be a combined heat and power plant with maximized fuel utilization, which supplies Moscow City, Moscow’s new international business center, with ecofriendly power and heat. Siemens will also present a high-efficiency combined cycle power plant for Singapore, which will contribute toward meeting the growing power demand in the Asian metropolis.

The London Array offshore wind farm, which Siemens is building in the Thames estuary approximately 20 kilometers off the coast of Kent and Essex and connecting to the British grid, will have sufficient capacity to provide a sustainable supply of ecofriendly electricity to approximately 750,000 British households. That is equivalent to around a quarter of the inhabitants of Greater London. The wind farm will reduce annual CO2 emissions by 1.9 million tons. Siemens will supply 175 wind turbines with a combined capacity of 630 megawatts (MW) for the offshore wind power plant. It is planned to increase the wind farm’s capacity to 1000 MW, thus making it not only the first 1-gigawatt-class wind farm but also, when completed next year, the world’s largest offshore wind farm.

Using the example of a successfully implemented smart grid solution for a utility in Texas, Siemens will show how the reliability of the utility’s power supply network and cost-efficiency can be enhanced. The utility’s supply area totaling 3.1 million households and companies includes in Dallas-Fort Worth the fifth largest city in Texas. Together with a partner Siemens developed and supplied a comprehensive distribution management system (DMS), which enables the utility to process vast amounts of information from a large number of systems in the grid. For this purpose the data is automatically collated, filtered and transferred to a structure to support concrete actions, so that grid operators can make the right decisions in optimizing power supply without any major delay.

Another project entails a combined heat and power plant, which supplies energy to Moscow City, Moscow’s new international business center. Siemens supplied two industrial gas turbines and one industrial steam turbine for this power plant. In combination the turbines not only provide Moscow City with an energy-efficient supply of electricity but also with district heating by way of cogeneration. The gas turbines have a combined capacity of 121 MW and the steam turbine has a heat output of 92 megajoules per second. The business center at the heart of Moscow comprises high-rise office blocks, restaurants, shopping malls, hotels and residential houses with a total floor space of more than 2.5 million square meters for approximately half a million people.

In Hanover Siemens will also be providing information on a high-efficiency cogeneration combined cycle power plant in Singapore. The plant attains a fuel utilization factor of over 75 percent and contributes toward meeting the growing demand of the Asian metropolis with ecofriendly, cost-effective power. For two new units at this power plant Siemens supplied the gas turbines, steam turbines, generators, heat-recovery steam generators, and the electrical and I&C equipment. Since October 2010, the power plant has been feeding power into the public grid and at the same time supplying process steam to a neighboring refinery operated by the Petrochemical Corporation of Singapore.

The combined cycle power plant ultimately contributed toward the fact that Singapore was in February crowned as the greenest megacity in Asia. That is the result of the Asian Green City Index – a study commissioned by Siemens with the independent research institute Economist Intelligence Unit (EIU). The EIU analyzed 22 Asian megacities with regard to their targets and achievements in terms of environmental and climate protection. Singapore is characterized in particular by its ambitious environmental protection targets and the efficient way in which it strives to achieve these targets.

With its Environmental Portfolio Siemens is the ideal partner for sustainable urban development focusing on energy and resources efficiency. The company offers the largest and broadest range of technologies for ecofriendly expansion of infrastructures – from efficient, clean power supply, transmission and utilization, to public transportation systems and water treatment plants. In fiscal 2010 alone, revenue from the Portfolio totaled about EUR28 billion, Its products and solutions enabled customers to reduce their carbon dioxide (CO2) emissions by 270 million tons, an amount equal to the total annual CO2 emissions of the megacities Hong Kong, London, New York, Tokyo, Delhi and Singapore.

Siemens Energy is represented at the Hanover Fair not only in Hall 8 but also in Hall 27, Booth E56.

The Siemens Energy Sector is the world’s leading supplier of a complete spectrum of products, services and solutions for the generation, transmission and distribution of power and for the extraction, conversion and transport of oil and gas. In fiscal 2010 (ended September 30), the Energy Sector had revenues of approximately EUR25.5 billion and received new orders totaling more than EUR30.1 billion and posted a profit of more than EUR3.3 billion. On September 30, 2010, the Energy Sector had a work force of more than 88,000. Further information is available at: http://www.siemens.com/energy
