Wind energy is at the center of the transition to a less carbon-intensive and more sustainable energy system.  Although the share of renewables in global electricity generation is rising, renewable power as a whole still needs to expand to meet decarbonization targets set by governments around the world. Siemens Energy is committed to driving this potential into real growth for the future of renewable power and offers a whole range of power transmission equipment, grid access solutions and services for the wind industry. To date Siemens Energy received orders for 21 grid connections with more than 12 gigawatts of offshore wind and produced more than 4,000 units of sustainable high-voltage products such as distribution transformers and switchgear for original equipment manufacturer of wind turbines.

WindEnergy Hamburg 2020

Siemens Energy at WindEnergy Hamburg 2020

Online, 1 December to 4 December 2020
Under the motto “Bringing wind home for tomorrow’s greener generation”, Siemens Energy is going to present its power transmission portfolio at the WindEnergy Hamburg 2020, a leading trade fair for the wind industry. It will take place completely virtual from December 1 to 4, 2020. At the event Siemens Energy is showcasing its state-of-the-art products, solutions, and services ranging from products and systems like eco-friendly distribution transformers or sustainable gas-insulated switchgear as well as turnkey grid access solutions to offshore wind services.
On the 1st of December at 14:00 (CET) Siemens Energy experts, namely Ulf Katschinski, Senior Vice President Switching Products & Systems, Tilo Else, Vice President Distribution Transformers, and Andreas Barth, Head of Grid Access, will discuss how the deployment of a sustainable grid infrastructure can be accelerated on the fair’s WindTV Open Stream.
We cordially invite you to join the event on the 1st of December at 14:00 (CET) live on the internet under the following link:

Alternating current (AC) or direct current (DC)? The best grid access solution depends on various factors including output and distance. As the world’s leading partner for offshore wind farm grid connections Siemens Energy has extensive experience in this area.
To date Siemens Energy accounts for 14 offshore grid connections with 6 gigawatts (GW) of alternating current transmission. Four of them (ca. 2.5 GW) with the company’s innovative Offshore Transformer Module (OTM) technology. The modular solution is significantly smaller in size and weight compared to conventional AC platforms. For the grid connection of the 950 megawatts (MW) Moray East Offshore Windfarm project in Scotland, Siemens Energy is connecting in a world’s first three of its Offshore Transformer Modules® (OTM).The greater the distance, the more important it becomes to minimize the unavoidable physical power losses, and this is where DC technology comes into play. To date Siemens Energy received orders for seven offshore grid connections with 6 GW of DC transmission. In the German North Sea alone the company successfully completed five grid connections with two more to come. A total of about seven million households will be supplied with electricity generated from wind power via these seven links. 

Transforming wind energy efficiently and reliably

Driving decarbonization with Blue technology
While wind turbines were producing 0.5 megawatt (MW) of power at a height of 40 meters in 1990, today’s wind turbines produce 10 MW and beyond requiring higher voltage levels and innovative technologies. To manage the voltage reliably and efficiently step-up transformers are crucial. They convert generated electricity to the requisite voltage level for power transmission on high-voltage lines and cables. 
For on- and offshore wind farms Siemens Energy delivered about 30.000 units of fire-resistant GEAFOL cast-resin transformers for up to 40.5 kilovolt (kV), 1.000 of them for offshore wind projects. More than 2.500 units of the company’s ester fluid immersed FITformer REN transformer were installed in wind offshore applications worldwide. The lightweight and compact transformers can be placed in the wind turbines nacelle and are equipped as Siemens Energy Sensformer, that means they come with inbuilt connectivity and optimized operation.

Driving decarbonization with Blue technology

Transforming wind energy efficiently and reliably
Switchgear protect the wind turbines from overloads and short circuits and thereby ensure an uninterruptible power supply. Siemens Energy’s gas insulated switchgear (GIS) of type 8VM1 was developed specifically for use in offshore wind turbines. The innovative switchgear represents an answer to new market requirements for two reasons: Due to increased wind turbine power, there is a movement to high voltage within the wind turbine network to decrease the current and therefore the cable losses. The GIS 8VM1 has a capacity of up to 72.5 kV, thus enabling higher voltages within wind turbines. As part of Siemens Energy’s eco-friendly “Blue Portfolio”, it utilizes vacuum interrupters for switching functions and clean air (industrially purified air) as the insulation medium representing an environmentally friendly alternative to the potentially climate-harming insulating gas sulfur hexafluoride (SF6).
An example: 1,400 tons of CO2 emissions can be saved by the application of one of Siemens Energy’s 8VM1 bay, compared to a standard SF6-filled gas-insulated switchgear bay.
Just recently, Siemens Energy commissioned an eco-friendly 66 kV power transmission system with a 8VM1 blue GIS, which complements one of China’s largest offshore eight-megawatt wind turbines.

Bringing wind home for tomorrow's greener generation
To date Siemens Energy has connected more than 12 gigawatts of offshore wind energy to the grid and produced more than 4000 units of sustainable high-voltage products such as distribution transformers or SF6-free switchgear for original equipment manufacturer of wind turbines.
Siemens Energy delivers technology for seventh offshore wind farm connection in the North Sea
In the German North Sea high-voltage direct current technology from Siemens Energy connects around 7 million households with offshore energy.

Siemens Energy will deliver 114 low-loss 66kV distribution transformers for the Seagreen Offshore Wind Farm in Scotland. The solution has been specifically designed to pass through the opening in the tower base without disassembly. Earlier Siemens Energy’s compact transformers also helped to enable the Deutsche Bucht offshore wind farm (in the picture) in the German North Sea, together with MHI Vestas Offshore Wind.
A growing number and size of offshore wind parks require efficient and sustainable systems for power transmission. Siemens Energy is committed to driving the potential of offshore wind energy into real growth for the future of renewable power and offers a whole range of power transmission products and systems, turnkey solutions, and services for the wind industry. 
To date Siemens Energy has connected more than 12 gigawatts of offshore wind energy to the grid. In the German North Sea alone the company successfully completed five grid connections with two more to come. The offshore platform of the grid connection BorWin3 in the picture can transmit up to 900 megawatts of wind energy, enough to supply over one million German households.
