The energy transition is transforming power generation
Previously
• Power generation oriented
towards consumption centers
Today
• Nuclear energy is going offline
step by step
• Wind energy is produced
primarily in the north
• Solar energy is produced
primarily in the south
Conventional
energy producers

Load centers

In the future current will have to cross distances >400 km
• Growing distances between
electricity generation and
consumption necessitate
additions to the transmission
network
• Three new transmission lines
will be built in Germany
• With the converters for the
ULTRANET network expansion
project, Amprion, TransnetBW
and Siemens are partnering to
shape the energy transition

HVDC links – a global issue
Long-distance transmission
E.g. Mundra-Haryana, India
Island interconnections
e.g. Australia-Tasmania
Coupling of asynchronous
systems
e.g. Georgia-Turkey
Energy trading
e.g. Netherlands-UK
Bulk-power transmission
E.g. Yunnan-Guangdong, China
Grid access for offshore
applications
E.g. North Sea platforms
DC for megacities
E.g. Hudson, USA
“Meshing” direct current
networks

Energy transition - paradigm change
The transition in figures: ~ 1.3 million prosumers in Germany
THE TRANSITION IN FIGURES: ~ 1.3 MILLION
PROSUMERS IN GERMANY
•
450 central power plants vs. 1.5 million distributed
generation points
•
Over 30% energy from renewable sources - three times
as much as in 2000 and therefore much more volatile
generation
•
Spatial separation of generation and consumption, with
most generation in the north and most consumption in
the south
•
Temporary reverse in power flow from lower to higher
voltage level
•
Loop flow in neighboring countries

2015: Redispatch in high wind (2)
•
High wind situations and storm systems (like Niklas) currently lead to feeds of 30 GW
(~ 85 % of installed capacity) from wind turbines.
•
Already about 20% of this production has to be reallocated by the TSO.
•
Market-related grid interventions are the order of the day.

New transmission paths
•
Planned new DC transmission corridors in Germany
Length 2600 or 3100 km (depending on the scenario)
Transmission capacity 12 GW
To Belgium, Denmark, Norway: 200 km
•
AC grid new construction planned
Length 900 to 1100 km
•
DC/AC grid strengthening planned
Length 5200 or 5800 km (depending on the scenario)

ULTRANET key figures
•
340 km
•
Transmission capacity: 2 Gigawatts
•
Voltage level: ±380 kV
•
Use of existing lines
•
Mostly hybrid lines: Direct and alternating
current on the same mast
•
The capacity of the line rises without
much change in appearance.
