Siemens Energy wins its largest order to date for grid connections

Siemens Energy has contracted a German offshore wind farm converter station technology contract worth more than 100 million euros, which is the largest offshore grid connection order
the company has received to date.

It is reported that Siemens Energy will provide converter station technology contracts
for the connection system of two offshore wind farms, DolWin4 and BorWin4, to the land grid.
The two connected systems will transport 1.
8 GW of green wind energy from several wind farms in Germany's North Sea to land, which can meet the electricity needs
of 1.
8 million residents.

"By 2030, the share of renewables in Germany's electricity supply will rise to 80 percent
.
Therefore, it is important to build new wind farms, but it will ultimately be meaningless
if the energy does not reach consumers.
We also need to invest in the grid to reliably provide sustainable energy to the country," said
Tim Holt, member of Siemens Energy Management Board.

Siemens Energy's supply scope includes offshore converter station platforms and land converter stations
.
These platforms convert alternating current generated by wind turbines into direct current
.
The direct current is then transmitted to the high-voltage direct current transmission cable (HVDC cable) for transmission
.
A second converter station on land then converts the power back to alternating current
.
Only then can a large amount of energy cover distances of approximately 215 km (DolWin4) and 280 km (BorWin4) without significant losses (low losses).

The two connections will be installed in parallel and are scheduled to start running
in 2028.
As a result, BorWin4 was connected to the grid
even a year earlier than originally planned.
Since the transmission grid in the coastal region of Lower Saxony is already heavily used by numerous wind farms, the connection point of the link is located far inland
.

In addition to providing the technology, Siemens Energy will take over the complete maintenance of converter station solutions for an initial period of 10 years
.
All high-voltage equipment for the two connected systems, such as converter technology, transformers and switchgear, will be manufactured
by Siemens Energy in Europe.

Currently, 9 of the 15 HVDC grid-connected projects in the North Sea in Germany use Siemens energy technology
.
At the same time, the UK wants to generate enough green energy from offshore wind to power every household in the country by 2030
.
The UK recently approved five more offshore wind farm projects, the largest round of contract
differentials ever.
According to the operator's current plans, four of the projects will be equipped with Siemens Energy's grid connection system
