Our Energy Sector is one of the world’s leading suppliers of a wide range of products, solutions and services in the field of energy technology.
We enable customers to generate, transmit and distribute electrical power at the highest levels of efficiency. We also help them produce, convert and transport the primary fuels oil and gas. We’re the only manufacturer worldwide with know-how, products, solutions and key components spanning the entire energy conversion chain.
In fiscal 2013 (ended September 30), the Energy Sector had revenues of EUR 26.6 billion and received new orders totaling approximately EUR 28.8 billion and posted a profit of approximately EUR 2 billion. On September 30, 2013, the Energy Sector had a work force of approximately 83,500.
High-voltage direct current (HVDC) transmission enables large quantities of electricity to be transmitted with few losses over great distances of more than 1,000 kilometers.
Electricity from renewable energies is seldom generated in cities. More often, it’s produced far away from the places where it’s needed most. As the following examples illustrate, our high-voltage direct-current (HVDC) transmission systems are transporting large amounts of electricity over great distances with minimal loss – all around the world.
We’ve built a 295-kilometer HVDC undersea cable connection between Australia and Tasmania that is capable of transporting up to 626 MWs of electricity. Long Island, New York and Sayreville, New Jersey have been linked by a 750-MW HVDC system since mid-2007. In India, our HVDC technology is improving the energy efficiency of the 660-MW link between Ballia and Bhiwadi while reducing annual CO2emissions by 250,000 tons compared to conventional alternating-current systems. In China, we have constructed the world’s first 800-kV HVDC system. The new system’s high voltage will ensure that losses during transport are even lower than with other types of HVDC transmission. Linking the Yunnan and Guangdong provinces, the system will transport up to 5,000 MWs of carbon-free hydroelectric power over a distance of 1,400 kilometers – reducing CO2 emissions by some 30 megatons a year.
In the future, floating wind turbines will be able to supply a substantial amount of energy.
It’s been 18 years now since our company first became active in the field of offshore technology. We’ve already installed several offshore wind farms and are currently involved in constructing a number of further projects. For instance, together with our Norwegian partner, StatoilHydro, we’re now testing the world’s first multi-megawatt floating wind turbine off the coast of Norway. The Hywind prototype turbine went into test operation on September 8, 2009. The pilot project aims to demonstrate that wind turbines which are not firmly anchored to the seabed can generate substantial amounts of energy. Located some 12 kilometers southeast of the Norwegian island of Karmøy, the innovative turbine is held by three steel cables moored to the seabed at a depth of 220 meters. Supplied by Siemens, the floating turbine has a capacity of 2.3 megawatts and a rotor diameter of 82 meters. It will be tested over the next two years, and the electricity generated will be transported to the mainland via a marine cable. All our turbines feature high corrosion protection, remote monitoring options, lightening protection systems and position lights. With over 800 megawatts of installed capacity and an order backlog of more than three gigawatts, we’re now the market leader in offshore wind power.
