Tomorrow's energy supply – local, sustainable and intelligent CIRED – The 21st International Conference and Exhibition on Electricity Distribution Dr. Andreas Roß, Managing Director Frankfurt, June 6, 2011

CIRED, Why “local” and why “sustainable”?
CIRED, 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 megawatts Source: Umweltbundesamt
CIRED, CHP share of at least 25% Combined heat and power CO 2 neutrality 20% of CO 2 neutral power generation 15% of which are from renewable energies Reduction of CO 2 emissions Saving of 550,000 tons of CO 2 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 exit 1) 1) cf.

CIRED, 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, Why “intelligent”?
CIRED, A sustainable, decentralised energy system requires intelligence – especially in the networks! We need intelligent networks to solve technical challenges such 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, "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, 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): billion euros by ) Bundesverband der Energie- und Wasserwirtschaft – BDEW (German Association of Energy and Water Industries): -up to 27 billion euros by ) Bundesnetzagentur (German regulation authority): billion euros spread "over many years" 1) cf.
