Why “local”and
why “sustainable”?
CIRED, 6.06.2011 9
Nuclear exit and the shift in energy policy require a sustainable, decentralised energy system
Power generation in Germany is still characterised by:
large central power plants
an oligopoly (E.ON, RWE, EnBW, Vattenfall)
an energy mix with close to 2/3 coal and nuclear power (status 2009)
However, to realise the nuclear exit and the energy system transfor-mation, we increasingly need:
decentralised generation capacities
utilization of renewable energies
bundling of municipal competence (capital and brain power)
German power plants 100 megawattsSource: Umweltbundesamt
CIRED, 6.06.2011 10
CHP share of at least 25%Combined heat and
power
CO2 neutrality20% of CO2 neutral power generation
15% of which are from renewable energies
Reduction of CO2
emissions
Saving of 550,000 tons of CO2 up to 2015
Sustainable, decentralised energy supply taking Mainova as an example
Main pillars of Mainova's generation strategy up to 2015
Mainova: planned investments of about 500 million euros up to the year 2015
According to the Verband kommunaler Unternehmen VKU (Association of Municipal Utilities), public utilities plan to invest additional 6 billion euros by 2020 in the event of a rapid nuclear exit1)

Sustainability and decentralisation offer advantages for citizens, municipal politics and administration
From our point of view, sustainability and decentralisation offer different advantages:
Strengthening the scope of municipalities to take action: political co-determination and subsidiarity
Acceptance by citizens: guaranteed implementation
Knowledge of location: planning reliability
Well-established relationship with local authorities: prompt action
CIRED, 6.06.2011 12
Why “intelligent”?
CIRED, 6.06.2011 13
A sustainable, decentralised energy system requires intelligence – especially in the networks!
We need intelligent networks to solve technical challengessuch as
dealing with future load development
managing fluctuating power in-feeds
balancing supply and demand
reducing network losses
avoiding investments by better managing concurrence
integrating electricity, gas and heat in generation, storage and transport
But we also need – above all – intelligence in the networks to solve strategic issues such as
What does the energy system of the future look like?
Who are the players and what roles will they play in this system?
Which roles will network operators assume?
How can the key processes of the network business be linked intelligently to the processes of other players (Smart Cities, eGovernment, Smart Mobility, etc.)?
CIRED, 6.06.2011 14
"Smart grids" have to be implemented differently at each of three levels!
Level: transmission system operators
"Electricity highways" (transnational transport and load balancing)
System stability
Level: regional distribution system operators
Investment requirements to handle in-feed from renewable energies
Increasingly fluctuating in-feed
Level: municipal distribution system operators
Load management ("balancing")
Integration of the electricity, gas and heat sectors in generation, storage and transport
CIRED, 6.06.2011 15
Extension and restructuring of networks requires investments!
Different estimates are currently available for the investment requirements to extend and restructure networks to become smart grids:
Verband kommunaler Unternehmen – VKU(Association of Municipal Utilities):
- 25-30 billion euros by 20301)
Bundesverband der Energie- und Wasserwirtschaft – BDEW(German Association of Energy and Water Industries):
- up to 27 billion euros by 20202)
Bundesnetzagentur (German regulation authority):
- 20-40 billion euros spread "over many years"
