Siemens is modernizing 15 converter transformers at the Cahora Bassa dam in Mozambique for the operator Hidroeléctrica de Cahora Bassa (HCB). The transformers form part of the HVDC transmission link built in the 1970s to transmit electrical power from the hydropower plant over a distance of 1,450 kilometers. The order volume is about €26 million, and the project as scheduled by Siemens will take three years.
As the global population experiences rapid growth, more people around the world are moving from the countryside to the city. In addition to the inner-city challenges posed by the urbanization megatrend, there is also an increase in the average traveling distance. As a result, the challenges for train systems are also increasing. To meet these demands, Siemens Mobility and Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) have jointly developed new auxiliary converters to improve the efficiency of on-board power systems using power semiconductors based on silicon carbide (SiC).

medium-sized buildings. The latest addition to the Siemens Xcelerator
portfolio, Connect Box is a user-friendly approach for monitoring building performance,
with the potential to optimize energy efficiency by up to 30 percent and to substantially
improve indoor air quality in small to medium sized buildings such as schools, retail
shops, apartments or small offices. Siemens Xcelerator is an open digital business
platform that enables customers to accelerate their digital transformation
easier, faster and at scale.
- Attica-Crete interconnection will ensure a more secure power supply and increase integration of renewable energy
- HVDC project will reduce half a million tons of CO2 emissions in first year of operation
- Total order volume for Siemens-led consortium €370 million
A consortium led by Siemens Gas and Power (Siemens Energy) has been awarded a turnkey contract for two converter stations for the Greek high-voltage direct-current (HVDC) link that will connect Crete, Greece’s largest and most populous island, with the mainland of Greece. The project will enable an exchange of electricity of up to 1,000 megawatts (MW) to enhance reliability of the power supply and facilitate integration of renewable energy sources in the power grid. Customer is Ariadne Interconnection S.P.S.A., a wholly owned entity of the Greek independent power transmission operator IPTO. Commissioning of the interconnector is scheduled for mid-2023. Total order volume for the consortium is €370 million.
- Low-loss transmission of wind
energy for 1.1 million households
- Further contribution toward
decarbonizing energy supplies
Siemens Energy is supplying the
high-voltage direct-current (HVDC) power transmission technology for a further
offshore connection in the German North Sea. A corresponding contract was just
signed by the German-Dutch network operator TenneT and the BorWin5 Offshore
Consortium, consisting of Siemens Energy and Dragados Offshore. In 2025, the
platform BorWin epsilon, which is part of the BorWin5 project, will begin the
low-loss transmission of electricity produced by the EnBW He Dreiht wind farm
off the island of Borkum to the Garrel/Ost converter station around 230
kilometers distant. The transmission capacity of 900 megawatts is calculated to
serve over 1.1 million households with electricity. The project is a further
contribution toward decarbonizing Germany’s energy supply. BorWin5 marks the
seventh HVDC offshore grid connection project undertaken by Siemens Energy in
Germany with TenneT.
- Siemens will upgrade control and protection system of Moyle Interconnector
- Refurbishment increases security of supply, improves integration of renewable energy and enhances provision of ancillary services
Siemens Gas and Power (Siemens Energy) has been awarded the project to refurbish the Moyle Interconnector, a high-voltage direct-current (HVDC) link between Ballycronan More in County Antrim, Northern Ireland, and Auchencrosh, Scotland. Owned and operated by Mutual Energy, the Moyle Interconnector control and protection system is almost 20 years old and is being modernized to enhance its operation. The refurbishment of the 500-megawatt interconnector will increase the security and reliability of the power supply to consumers in the United Kingdom. The project to upgrade the technology originally installed by Siemens in 2001 is now underway and the refurbishment is scheduled to be completed in September 2022.
- An Avenio vehicle equipped with SiC technology spent one year transporting passengers in Munich and covered 65,000 kilometers in the process
- Energy use was cut by 10 percent and motor noise was reduced as well
- Joint research project conducted as part of the European development and research program PINTA
Siemens Mobility and Stadtwerke München (SWM) successfully completed a one-year test of semiconductor technology based on silicon carbide (SiC) in an Avenio streetcar in Munich in August. They have now presented the results of their research. The study found that the motor noise produced by the vehicle fell sharply and that energy use declined as well during the trips that the tram made on Munich’s public-transportation rail network. The semiconductor technology was produced by Infineon Technologies. The tests were conducted as part of the European research and development project PINTA. By taking part in the trial, Siemens Mobility significantly contributed to efforts to integrate SiC power semiconductors into rail vehicles.
The digital transformation of the producing industry is gaining momentum. Companies from a wide variety of industries are already unlocking this potential – they are using end-to-end digitalization to create a lasting competitive edge by reducing time to market and increasing flexibility, efficiency, and quality. With Siemens Digital Enterprise solutions the technical prerequisites for the implementation of Industrie 4.0 are available and can be deployed in every application and companies of all sizes. At the SPS IPC Drives in Nuremberg, Germany, from November 27 to 29, 2018 – which took place this year under the motto "Digital Enterprise – Implement now" – Siemens showed in hall 11 how this can be done.
- Dynamic load flow control solution for grid stabilization and resilience
- UPFC PLUS controls load flow in milliseconds
- Facilitating the increasing integration of renewable energy
With its new Unified Power Flow Controller, called UPFC PLUS, Siemens Energy is expanding the options for grid stabilization. The UPFC PLUS will help system operators stabilize the grid by dynamically controlling the load flow in alternating-current grids. Easy to integrate into existing infrastructure, the UPFC PLUS improves the efficiency of today’s power grid while providing the grid stability and resilience required in the ever-changing energy landscape.
