With its products and solutions, Siemens is making a significant contribution to the energy transition. One milestone along the way to a new energy system was the installation of the HelWin1 platform in the North Sea. This substation on the open sea transforms the alternating current generated by the wind turbines into direct current, which can be transported to shore with minimal loss. HelWin1 will link the Nordsee Ost and Meerwind wind farms to the mainland. Starting in 2014, network operator and client TenneT will be able to supply clean power for more than 500,000 households on the German mainland.
Siemens technology is also the global leader in conventional power plants: The company is constructing the Lausward combined-cycle power plant (CCPP) for Stadtwerke Düsseldorf, the city’s public utility. The Siemens SGT5-8000H turbine alone achieves a peak efficiency level of more 61 percent. In conjunction with the extraction of energy for district heating, the new power plant will even be able to harness roughly 85 percent of the energy of natural gas. This will make the new power plant in Düsseldorf one of the most efficient and environmentally friendly power plants in the world.
Environmental protection is a high priority even with other energy system components. For that reason, Siemens has developed and manufactured the world’s first large transformer that uses vegetable oil. Transformers are usually cooled and insulated with mineral or silicone oils. Compared to these oils, however, vegetable oils are more ecofriendly and are less flammable. In the future, the new transformer at the Bruchsal-Kändelweg substation near Karlsruhe will connect the 380 kV extra-high-voltage level to the 110 kV network.
Diagnostic equipment from Siemens helps to detect diseases at the earliest possible stage and improve patients’ chances of recovery. The Biograph mMR helps as well. This is the first device in the world to combine magnetic resonance imaging (MRI) and positron emission tomography (PET) in a single system. It enables doctors, for the first time, to simultaneously detect changes in the structure of organs, their function, and their metabolism. Biograph mMR is now being used in routine medical care: The trailblazer in Germany was The Center for Modern Diagnostics (ZEMODI), a regional group practice for radiology and nuclear medicine in Bremen.
With conventional ultrasound devices, the transducers are connected to the system with a cable, which limits the mobility of the doctor, increases the time for an examination, and under certain circumstances can pose an infection risk. Siemens thus developed the world’s first wireless ultrasound device and introduced it in Chicago. With the Acuson Freestyle, the transducer is wirelessly linked to the system, and data is transmitted via a new type of ultra wideband radio technology that operates at a very high frequency of 7.8 gigahertz.
With help from Siemens, the University Medical Center Hamburg-Eppendorf (UKE) became the first paperless hospital in Europe. All information, including patient data, X-ray images, and temperature curves, is available digitally for all hospital employees simultaneously – during patient consultations, examinations, therapy, or on mobile devices while doctors are making rounds. State-of-the-art IT systems provide increased transparency, prevent repeat examinations, and conserve valuable natural resources.
With “availability models,” Siemens Healthcare helps customers to bundle their cost structure, optimize procurement processes, and keep pace with increasingly shorter innovation cycles: Over a period of several years, Siemens provides customers with state-of-the-art medical technology. This enables hospitals and medical practices to safeguard their competitive edge and plan and budget effectively. One of the latest partnerships is with the Alb Fils hospitals: The contract includes the innovation and maintenance of 26 systems in total, a service contract for the major imaging equipment, and a training concept. These steps reduce the average system age of the hospital from 12 to six years – without increasing the annual budget.
With state-of-the-art manufacturing processes, Siemens helps industrial companies to become more productive, efficient, and competitive. With its unique portfolio of automation technology, industrial switchgear and drive technology, and industrial software, Siemens equips the entire value-added chain of companies with state-of-the-art technologies – from product design and development to production, sales, and service.
Based on the proven PROFINET standard, the new PROFIenergy data interface is making a tangible contribution to achieving greater energy efficiency. PROFIenergy makes it possible to switch several or all consumers in a production line to an energy-saving mode during downtimes. Thanks to these breaks controlled by PROFIenergy, the energy consumption and the carbon dioxide emissions per produced unit were significantly reduced at Daimler. The energy and production costs dropped – without slowing down production – and the environmental profile was improved.
Siemens software also reduces energy consumption at Volkswagen. The automobile manufacturer purchased a crane system equipped with Siemens software for its press shop in Hanover. The new system has significantly increased productivity and improved production efficiency while reducing energy consumption by 30 percent compared to the old system.
Siemens is also helping to discover distant stars and planets: Using Siemens’ NX CAD software, engineers at OptoTech Optikmaschinen GmbH in Wettenberg were able to optimally plan their UPG 2000 CNC precision optics machine and, with the help of NX CAM Siemens software, manufacture the components without defects. A SINUMERIK 840D-CNC from Siemens controls the machine, and a SINAMICS drive is responsible for the precise movements of the eight-axis ultra-precise generating and polishing machine. The device manufactures highly precise telescope mirrors that are used for astronomy research and designed to concentrate the weak light from space.
For research and testing purposes, the Siemens Infrastructure & Cities Sector and Stadtwerke Krefeld AG (SWK) will work together to convert the existing power supply grid in Wachtendonk on the Lower Rhine into a smart grid. Siemens is supplying the components for the intelligent transformer substations, smart meters, as well as the measuring, monitoring, and communication technology. SWK will link these individual components to form a smart system and will test it in specifically selected low-voltage grids. Efforts will additionally focus on developing and ensuring the data transmission to the SWK control center. Through this project, Siemens and SWK will develop detailed information regarding the behavior of a distribution network with a disproportionately large share of renewable energy sources. Another objective is to test the practical application of technical components to gain insight into the further expansion of smart grids.
Energy performance contracting from Siemens protects the environment and enhances the comfort of individuals who work and study at Hamburg University of Applied Sciences (HAW Hamburg). Siemens renovated the heating and ventilation systems – parts of which were more than 40 years old – to provide better heat distribution and to ensure a more comfortable room climate. In addition, the project includes guaranteed annual savings in energy costs amounting to EUR 500,000 and an annual reduction of CO2 emissions by approximately 2,000 tons. Crucial factors behind HAW’s decision to use energy performance contracting were the guaranteed energy and cost savings, the longterm economic viability, and the sustainable concept from Siemens. With this same approach, Siemens has modernized the energy systems in approximately 1,800 buildings in Germany – with guaranteed savings totaling EUR 310 million and a CO2 reduction of approximately 1.3 million tons.
The Siemens Building Technologies Division is supplying the complete safety and security technology and building automation for the new TaunusTurm highrise building in downtown Frankfurt. The project includes 5,000 loudspeakers for the voice alarm system, 6,600 Sinteso fire detectors, network-based video technology, access control systems, intrusion detection technology, intercoms, garage technology, and a radio system for buildings. All of the systems are linked via a security management system to form a holistic safety and security solution. The Desigo PX building automation system provides optimal energy efficiency with approximately 7,000 data points, which can be used to help regulate and control the heating, ventilation, and air-conditioning (HVAC) technology throughout the building in a highly energy efficient manner. Once the 40-story building is completed at the end of 2013, the TaunusTurm is expected to become the first new high-rise in Frankfurt to be LEED (Leadership in Energy and Environmental Design) Platinum certified.
In Brandenburg, the state government in Potsdam relies on state-of-the-art fire safety and security technology from Siemens: The company has modernized about 20 buildings that house various agencies such as the Ministry of Justice, the Ministry of Economic and European Affairs, and the State Chancellery. The safety and security technology includes a new Sinteso FS20 fire detection system, a CIC 1000 intrusion detection system, and an intercom and video surveillance system from Siemens. They can be connected via IP protocol to the security center for information and positioning service. The danger management system forms the centerpiece of the new fire safety and security technology: All information from the security systems is directed to this integration platform, where it can be monitored and controlled at a central location.
The Siemens Low and Medium Voltage (LMV) Division will supply Vulkan Energiewirtschaft Oderbrücke GmbH (VEO) with a Siestorage battery storage system that will ensure the black start capability of the gas turbine at the Eisenhüttenstadt power plant. If a failure occurs in the local distribution network, the blast furnace gas-fired power plant supplies electricity and heat to the steel mill of ArcelorMittal Eisenhüttenstadt GmbH (AMEH). To enable the gas turbine to start from a de-energized state, a motor brings the turbine up to a minimum speed. During a power outage, this motor draws its current from the battery storage system and thereby safeguards the energy supply. Siestorage is based on lithium-ion batteries and is designed for VEO with a power ratin of 2.8 megawatts and a capacity of 720 kilowatt hours.
