1 Energy Efficiency in Energy Consumption Achim Neuhäuser Berliner Energieagentur GmbH CODE, 2nd Regional Workshop Budapest, 6th May 2010

2 General Information on Berlin Berlin A City and a Federal State Statistics: Surface area: c. 892 km²* Inhabitants: t 3.4 m Density: 3,750 inhabitants per km² GDP: 87.5 billion * 1 square kilometre = sq. mile Source: Senate Department for Health, Environment and Consumer Protection, Berlin

3 BEA Facts and Figures Foundation in 1992 as Public-Private Partnership Shareholdersh Federal State of Berlin Vattenfall Europe GASAG KfW Banking Group Disposes of 2.5 million of capital stock Energy Services Contracting Consulting International Know-How Transfer Based in Französische Straße Berlin Phone: (030) Internet: Annual Turn-Over approx. 6.5 million 370 K Company earnings (EBIT) Know-how 50 members of staff

4 BEA Facts and Figures Energy Services Contracting: Planning, financing, construction, o and operation o of CHP and Heat stations, s, of special supply components such as emergency power, cooling energy and compressed air, solar energy as well as lighting systems Consulting: Advice on all aspects of efficient energy use for customers from industry and commerce as well as the housing, service and public sector International Know-how Transfer: Transfer of successful models of efficient use of energy and of the deployment of renewable energy to developing markets Generation Data at about 60 sites in the region of Berlin 27 CHP-units (incl. 5 micro CHP), annual electricity generation ca. 5,600 MWh direct electricity supply for around 1,500 households in Berlin CO2 savings of ca. 2,240 t/a

5 CHP Technologies (1) M G G motor / generator gas turbine / generator vegetable oil bioethanol fuel oil natural gas coal wood and straw fuel CHP unit electricity heat biogas municipal waste fuel cell steam turbine / generator G

6 CHP Technologies (2) Stirling Motor Fuel Cell Block CHP (Otto) Block CHP (Diesel) Steam Turbines Gas Turbines Gas and Steam CHP Thermal Capacity kw 2 kw 150 MW 7 kw 6 MW 10 kw 25 MW 1500kW 1,500 2,500 MW 50 kw 700 MW MW Electric Power 1 1 kw 1 kw 5 kw 40 kw 100 MW 5MW 20 MW 500 kw > 1,000 MW 25 kw MW 700 MW Total Utilisation Ratio up to 0.85 up to 0.9 up to 0.9 up to 0.9 up to 0.9 up to 0.85 up to 0.9 Electric Utilisation Ratio Usual Fuel Gas, Wood Gas Gas Diesel (Gas) Coal, Waste Gas, Diesel Gas (Coal)

7 CHP in Berlin Accomplishments and Aims Central CHP Total DH system in Berlin: over 1,500 km length (No 1 in Western Europe) 42 % of power consumption in Berlin is coming from CHP (No 1 in Germany) Ca. 11,500 GWh/a heat (30% of the demand in Berlin) CO 2 emission: ca. 150 g/kwh (separate generation of energy: g/kwh) Decentralized CHP 230 block-chp in Berlin High potential of gas driven block-chp

8 CHP and District Heating Example of Heizkraftwerk Mitte Plant operator: Vattenfall Europe Berlin Construction phase: Gas and Steam Cogeneration Plant 398 MW heating capacity 440 MW electric capacity Utilization ratio: 90% Very high CHP coefficient > 1

9 CO 2 -saving Potentials of Mini-Block-CHP in Berlin Block-CHP < 50 kw el Scenario: Realisation of the total potential, which is technically possible Maximal CO 2 - savings: maximal quantity ~ 1,325,000 t CO 2 /a

10 Combined Heat and Power Good Practice Residential Building Cooperative Bremer Höhe, Berlin 516 residential units and 16 businesses Roof-heating stations with boiler system and CHP modules to provide heat and power CHP-units 1 x 34 kw el / 80 kw th 2 x 18 kw el / 43 kw th Condensing boiler 531 kw and 2 x 950 kw heat Environmental effects: Amount of energy savings 600 MWh p.a. Carbon Dioxide savings: 225 t p.a.

11 Energy Services General Project Scheme local gas supplier Energy service company (Contractor) energy services customer back-up supply re-feeding local electricity utility financing, planning, construction & operation of supply unit heating, cooling, electricity emergency power

12 Trigeneration Trigeneration Königstadt- Terrassen Berlin Electricity Demand CHP unit 214 kw th 120 kw el In summer trigeneration units can produce cooling energy for Heating Demand air conditioning or industrial purposes in buildings Cooling Demand Powered only by heat, absorption chillers provide energy for cooling systems independent of electricity Hydraulic to compression Switch refrigerating production District i t Cooling Potsdamer Platz Berlin Up to 30% less of primary energy needed compared Higher investment costs compared to compression Boiler Boiler chiller units 1,400 kw 500 kw CHP unit 214 kw th 120 kw el Absorption Chiller 350 kw Grid Trigeneration with Mini-CHP

13 District Heating and Cooling Example of Trigeneration at Potsdamer Platz 3 absorption chillers in combination with the local DH-system District cooling system: 7.5 km main length Total cooling capacity: 36.6 MW, ca 46,000 MWh/a Absorption chillers: 7.5 MW ca. 9,400 MWh/a cold production DH-heat: MW, ca. 12,500 MWh/a Driven by gas and steam cogeneration plant Heizkraftwerk Mitte CO 2 saving potential: up to t/a

14 Urban Strategies and Action Plans CHP Pilot City Berlin Starting position: Berlin CHP hot spot 42 % of power consumption (No 1 in Germany) 1,500 km district heating grid (No 1 in Western Europe) Need for action: Knowledge and interest Sensitize all relevant stakeholders Initiate interest in innovative CHP energy solutions Approach: broad information campaign Place CHP as enabler for climate protection Trigger eagerness ess for knowledge

15 Urban Strategies and Action Plans Communication to the general public Press Conferenc e Website Posters and Ads Brochure Communication to special target groups Teaching Symposia Pilot material project BEA, GASAG, Vattenfall, SenGUV

17 CHP in Berlin What s next? Aims Increase use of regenerative fuels Expansion of the DH network, remarkable increase of the decentralized CHP 60 % of CHP-power consumption in Berlin (until 2020) Substitution of CO 2 -intensive heating technologies Combination of smaller units in virtual power stations

18 KWK Modellstadt Berlin CHP in other pilot regions or cities CHP goes Green ¾ Start: 1st June 2010 still under negotiation with EACI ¾ For example: ¾ Paris: 440 km district heating ¾ Frankfurt: 150 decentralised CHP units ¾ Riga: Big biomass potential for RES in CHP
