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

Wind energy

Solar energy

Load centers

Conventional energy producers


In the future current will have to cross distances >400 km

ULTRANET

• 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


Europe also needs new HVDC links

• Large-area balancing of local

power surplus and deficits

• Reliable and economical long-

distance transmission systems,

e.g. for energy trading

HVDC links – a global issue

Island interconnections

e.g. Australia-Tasmania

Coupling of asynchronous

systems

e.g. Georgia-Turkey

Long-distance transmission

E.g. Mundra-Haryana, India

Energy trading

e.g. Netherlands-UK

Grid access for offshore

applications

E.g. North Sea platforms

DC for megacities

E.g. Hudson, USA

Bulk-power transmission

E.g. Yunnan-Guangdong, China

“Meshing” direct current

networks

Offshore grid links and Interconnector

Interconnector • Double the power exchange capacity

• Increased supply security

• Integration of renewable energy sources without

endangering grid stability

Offshore grid links • Dependable grid connection >100 km from the coast

• Currently four Siemens platforms in operation

• BorWin3 commissioning planned for 2019

Ultranet Converters

A joint project of Amprion GmbH and TransnetBW GmbH April 8, 2016 Dr. Werner Götz, TransnetBW Trade press conference in Nürnberg

• Employees: 580 (January 2016)

• Revenue: € 5.9 billion (fiscal 2014)

• Wholly owned subsidiary of EnBW Energie

Baden-Württemberg AG and certified

independent transmission system operator

• Supply area:

34,600 km²

Power circuit length: 3472 km

Peak power in Baden-Württemberg:

approx. 11 GW

Electricity demand: max. 62 TWh

TransnetBW – the company

Energy transition - paradigm change

• 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

The transition in figures: ~ 1.3 million prosumers in Germany

THE TRANSITION IN FIGURES: ~ 1.3 MILLION

PROSUMERS IN GERMANY

DIMENSIONS OF SUPPLY

SECURITY

• National vs. European:

Own production or copper plate?

• Integration of renewable energy

• System stability

Energy transition - supply security

Germany’s energy future...

• Long distances between generation

and use

• Power transmission up to 800 km

• European internal electricity market

and trading

• Large volume of fluctuating

renewable generation

... is already here!

2015: Redispatch in high wind (1)


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.

2015: Overloading of “side routes” in other countries

• Heavy north-south trade flows

towards south and southeast Europe

• Strong physical transit flows

e.g. via Poland, Czech Republic and

Slovakia and further south

• Stress on foreign networks

Example from August 2015:

Because of unavailability of additional KW,

Poland could not meet its electricity

demand and had to cut off industrial users.

2023: Continued progress of energy transition

Source: NEP 2025, 2nd draft of Feb. 29, 2016

Decrease in controllable generation Increase in renewable capacity

The energy transition - ULTRANET as a solution module

• 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)

• Investment volume:

27 to 34 billion euros (depending on the scenario and

amount of wiring)

The need has been officially confirmed and set by law.

Amprion – the capable energy grid

Platzhalter für ein Bild

~29 MILL. people

are supplied with energy

by the Amprion.

11,000 KM is the size of the

Amprion transmission

grid.

~59 GW is the total capacity of all

power plants in the Amprion

grid.

1100 employees work at

Amprion.

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.

... to implement the next generation grid today

It started with an idea ...


But how? HVDC PLUS: the right technology for every application

Full-bridge module

Tested in more than 100 industry references

Half-bridge module

So far used in all HVDC PLUS installations
