DAS ENERGIEREFERAT - Municipal Energy Agency Frankfurt on the way to 100 % renewables Wiebke Fiebig Head of Energy Department, City of Frankfurt, Germany Frankfurt, June, 28th, 2017 1
Target: 100% renewables by 2050 50 % reduction of energy consumption by 2050
50 % of the supply will be provided from within the city of Frankfurt itself 50 % of the energy needed will be delivered by renewables from the surrounding Rhine Main region
Energy supply will be sustainable in terms of social, technical and economical aspects Source photo: Mainova 4
Expenditure for energy supply In Frankfurt, nearly 2 billion Euro per year are being spent for energy Renewables are a chance to increase the added value by keeping the money in the region
Challenge Expanding renewables Potential of waste, biomass and water is already used to a great extend Few open spaces left in the city Greatest potential: reduction of energy consumption
Result of the study: by 2050 Frankfurt will be able to supply its requirements solely with renewables
Structure of the energy system Frankfurt 2050 based on an hourly simulation done by Fraunhofer ISE 2014 Federal state»hessen«surrounding region»frankfurtrheinmain«wind PV Hydro Generation on cityarea 22% 20% 84% 0,4% Export District Import -18% 10% Electricity 24% Building level Storage 2.0 GWh 5% -5% City of Frankfurt am Main 4964 GWh 100% Consumer Local mobility 17% Efficiency: Reduction of the energy demand from 2012 to 2050 From fossil fuels + electr. to electric vehicles only - 79% Waste Solid Biomass Biogas 23% 17% 6% CHP CHP CHP CHP Boiler Heat pump Residential 9% 21% Services 32% 18% - 64% - 72% - 53% - 78% Solar thermal All data final energy Total generation 9759 GWh District and heating 42% industry 12% 22% Heat 36% Storage 2.3 GWh 5276 GWh 100% Industry 42% 61% - 11% - 10%
It is time for a transformation We, as a society, need to rethink the way we use energy and create a better awareness of energy consumption
What actions can we take to protect our climate?
Together with the FrankfurtRheinMain Region- Cooperation Agreement since 2013 Compilation of a regional energy concept Joint implementation of projects Involvement of all the stakeholders in the region Establishment of long-term cooperation
Together with partner cities Cooperation in city networks theme-based work group Joint statements on political processes Creation of key general frameworks for climate protection at local government level Transfer of knowledge and exchange of experience 12
DAS ENERGIEREFERAT - Municipal Energy Agency To reach this target, we need to reduce our energy demand by at least 70 % for buildings
Renewal Cycle: Today's new buildings and renovated buildings will not be substantially renewed again before 2050
What type of energy standards do we need now for different types of buildings in order to reach our climate goals? Measure: Development of an internet-based simulation program
City of Frankfurt - Leading by example: New municipal buildings and retrofitting - the best energy efficiency standard we know Passive House
DAS ENERGIEREFERAT - Municipal Energy Agency Considering energy efficiency by reconstruction of the old town center special energy consulting Source: Dom Römer GmbH
Example: Innovative project of the municipal housing company - the Active Town House Combines energy efficiency with renewable energies The building should produce more energy than it needs Tenant gets energy credits 18
85 % of the buildings in Frankfurt are over 30 years old Retrofitting is one of our main focuses Measure: Municipal funding programms for energy retrofitting Budget per year: 1 million Foto Quelle: Arch + E, Bad Vilbel
Example: Free advice for home owners concerning energy-efficient retrofitting Establishment of an Energy Advice Centre
Outlook Energy Concepts Development of energy concepts for existing residential areas Involvement of the local stakeholders Introduction of local retrofitting managers as contact persons and energy advisors Results should be the basis for developing a retrofitting road map for the whole city 21
Benefits: More comfort and reduced energy costs for inhabitants
Expansion of district heating an important strategy Strategic direction Conversion to renewable energies Cascading and low temperature grids District cooling Diverse Feed-in-sources (Solar thermal, excess heat) 23
Vision of district heating in Frankfurt Technical and ecological transition Open heating network : Industrial surplus Biomass CHP Heating Network Heat Store Solar and Geothermal input Heat pumps Self supply (CHP) (electricity) Heat from CHP Power to heat/gas Source: Fernwärme 3.0, HIR Hamburg Institut Research ggmbh, 19.02.2015/ Mainova 24
Vision district heating data center Producer of excess heat for district heating Customer base using district cooling
Strategic direction Industry sector biomass preferable for industrial sector and cogeneration Use of the waste heat and Hydrogen infrastructure Infraserv Höchst
Possible actions for local authorities- our strategy in Frankfurt Cooperation with local energy supplier Development of energy concepts for new urban and existing residential areas or for industrial estates Waste heat map registration of potentials in Frankfurt 27

Together we can change the world Thank you for your attention 29
