- Greenlink interconnector will increase power supply security and foster the integration of
renewable energy
- Consortium of Siemens Energy and Sumitomo Electric to supply HVDC cable and converter
technology
Siemens Energy, together with its consortium partner Sumitomo Electric, have signed a contract
with Greenlink Interconnector Limited. Siemens Energy will deliver the high-voltage direct current
(HVDC) converter technology for the 190km electricity interconnector Greenlink. The 500-
megawatt HVDC link will connect the power grids of Ireland and Great Britain. As the power can flow in either
direction, depending on supply and demand in each country, it allows both countries to benefit
from increased grid stability, security of power supply and cost-effective growth and integration of
low carbon energy. Work will begin at the start of 2022 following financial close.
- Framework agreement for construction and upgrade of substations in Southern Norway
- Norway is a front-runner in phasing out climate-harming gases in power transmission
- Siemens Energy’s vacuum interrupter technology in combination with clean air insulation
reaches almost 6-million hours of commercial operation
Siemens Energy and Norwegian distribution system operator Lyse Elnett signed a framework
agreement to strengthen the Norwegian power grid. Under this agreement, Siemens Energy will
provide services and transmission products for various substations in the Sør-Rogaland region in
Southern Norway. By constructing new substations and modernizing existing ones, Lyse Elnett not
only rises to the challenges of increasing energy demand and the volatile feed-in of renewables: the
framework agreement also stipulates that Lyse Elnett can, over time, fulfill its objective of more
environmentally friendly power transmission by eliminating fluorinated gases (F-gases) in their
substations.
On June 5 (World Environment Day*), Siemens Energy and Mitsubishi Electric signed a Memorandum of Understanding (MoU) to conduct a feasibility study on the joint development of high-voltage switching solutions with zero global-warming potential (GWP) that substitute greenhouse gases with clean air for insulation. Both companies will research methods for scaling up the application of clean-air insulation technology to higher voltages. They’ll start with a 245-kV dead-tank circuit breaker that will speed up the availability of climate-neutral high-voltage switching solutions for customers around the globe. Both partners will continue to manufacture, sell, and service switchgear solutions independently.
- SuedOstLink will transport environmentally friendly electricity from northern to southern Germany
- High-voltage direct current transmission enables low-loss transport of up to two gigawatts over more than 500 kilometers
The demand for renewable energy is rising. In 2020, global production of electricity from renewable sources, such as wind or solar energy, increased by 10.3 percent. Most environmentally friendly electricity in Germany is produced on land and at sea by large wind power plants in the north. At the same time, Germany also needs electricity in its south region where most industrial plants are located, and a growing number of conventional power plants are being taken offline. To ensure a continued reliable supply of energy in Southern Germany, transmission system operators 50Hertz and TenneT are planning to build the SuedOstLink electricity highway. It will transport excess energy from northern Germany and ensure that green electricity can be supplied to the South. Siemens Energy will deliver the converter technology, that will enable the low-loss transport of electricity over more than 500 kilometers.
- Two static synchronous compensator (STATCOM)
systems and two synchronous condensers will ensure stability of Italian
grid
- First space saving, single
phase and containerized 125 Mvar STATCOM solution
Italian transmission system
operator Terna. S.p.A (Terna) has ordered two static synchronous compensator
(STATCOM) systems for grid stabilization from Siemens Energy. It is Siemens
Energy’s first STATCOM order from Italy and will help the country meet new power
grid challenges posed by the energy transition.
- Supply of Ireland’s first turnkey synchronous condenser system
- Installation of the world’s largest flywheel
- Ensuring grid stability by
providing sufficient inertia, short-circuit power and reactive power
Siemens Energy will supply a synchronous
condenser system to the Electricity Supply Board (ESB), Ireland’s leading
energy company. The grid stabilizing system will be developed at the Moneypoint
power station located in South-West Ireland near Kilrush, County Clare. ESB
recently announced the launch of Green Atlantic @ Moneypoint, an ambitious plan
to transform the County Clare site into a green energy hub, where a range of
renewable technologies will be deployed over the next decade with the capacity
to power 1.6 million homes.
- Finland’s first SF6-free gas-insulated switchgear will enable climate-neutral power transmission
- Zero global warming potential due to vacuum interrupter and clean-air insulation technology
Siemens Energy has been awarded a contract to deliver ten bays of sulfur hexafluoride(SF6)-free
gas-insulated switchgear (GIS) to Fingrid, Finland’s transmission system operator. It will be the first
GIS in Finland that replaces SF6 as the most potent greenhouse gas in the world with “clean air”, a
pure mixture of nitrogen and oxygen with zero potential for global warming. It represents Siemens
Energy’s largest order for SF6-free high-voltage GIS in Europe to date.
- Systems will be among the most powerful STATCOM installations worldwide
- Innovative grid-supporting technology for stabilizing important nodes in the German
transmission power grid and for a successful energy transition
German transmission system operator Amprion has commissioned Siemens Energy with the
construction of two static synchronous compensator (STATCOM) systems based on SVC PLUS technology to further
stabilize the German transmission power grid. The plants will be in Polsum (North Rhine-Westphalia) and Rheinau (Baden-Württemberg). Both systems are designed for a reactive power
range of +/- 600 Mvar making them among the most powerful systems in the world. In addition,
the STATCOMs will feature innovative grid-supporting control mechanisms allowing the systems to
efficiently compensate for increasing voltage fluctuations in the electrical transmission network.
- SensSolution® connects turnkey transmission solutions securely to the cloud
- Full substation transparency, anytime, from anywhere
- Supports system availability and operational efficiency
- Company’s high-voltage direct current systems will be equipped first with SensSolution technology
Siemens Energy launches the world's first power transmission solution with holistic cloud connectivity and designated web application suite at Hannover Messe, Germany. SensSolution enables the secure transmission of substation data to the cloud, allowing for valuable real-time analyses and monitoring, supporting system operation and availability as result. Siemens Energy will deploy SensSolution to its complete transmission solutions portfolio, starting now with high-voltage direct current systems (HVDC).
- Siemens Energy extends its
digital power transmission portfolio for a successful energy transition
- Grid operators will be able to
make the right decisions faster to operate the grid more efficiently
- Highest cybersecurity standards
due to on-site data processing and storage directly in the substation
The energy transition is challenging the
power grids: Wind and sun feed in renewable energy in a highly fluctuating
manner, and the complexity and connectivity of our energy infrastructure
continues to grow. At the same time, the importance of cybersecurity is
increasing, because more and more components are digitally networked and thus
potentially vulnerable. This poses major challenges for grid operators. For the
energy transition, the digitization of transmission infrastructure is playing a
decisive role. Siemens Energy is extending its switchgear and transformer portfolio
to include new digital products such as the world's first high-voltage system
with integrated edge computing technology. With these innovative products, grid
operators will be able to react faster to changes in the system, make the right
decisions, and increase the transparency, productivity, and reliability of
their plants. The seamless integration of the systems into the existing
customer network is local, secure and simple. This also ensures a highly
cyber-secure system.
