1. Waternet, oktober 2011 Rob Kemmeren Jannnis van Zanten Waternet Heat and cold

2. Summary introduction Policy of the municipality District heating: explaination; usefullness and neccesity Central or decentral megadeal

3. Amsterdam Energy demand 4 billion kWh 850 million m3 natural gas Amsterdam 760.000 inhabitants 400.000 houses 8 million m2 office space

4. Seweage system Drinking water Groundwater; Waterway Management Surface water; Sewage treatment plants

5. Energy strategy2040 Energystrategy reliabale, affordabele, sustainable City council: two motions: “heat, unless…” and “climate neutral buillding” Energytransition: –heat: replacement conventional gas by different sources (wasted heat, geothermal, heatpumps) –cold: replacement electricity by different sources (districtcooling, districtheating)

6. CASCADING: ELECTRICITY High voltage: 380.000 V Industrial 700 V Industrial: 400 V household: 220 V E power plant, gas, coal, nucleair, wind off shore Wind on shore Solar cells middle: 10.000 V Middlevoltage: 50.000 V

9. Total real estate (totale heat demand Real estate intensity (heat demand / ha) Individual solutions Urban area: collective solutions Choice: collective or individual Building, optimalisation

10. All possible sources –now: gas fired power plant; 50% CO2 reduction; Waste incineration: 80% CO2 reduction; RWZI: 100% sustainable No source is excluded (eg: gas-infra excludes geothermal or straw-burning). Most optimal exergetic use of gas; Combination Heat and Electricity grids: future ready

11. Example sustainable source: RWZI Waternet – waste incineration AEB RWZI Waternet Waste incinetarion AEB sludge biogas elektricity heat

12. Sustainability in the whole chain! The grid Isolate Buffer Close ring Consumer Isolate Low temperature cold Bron: Choose the most sustainabele source (see next sheet) NB: passive ≠self sufficient

13. Decreasing heat demand in 30 jaar Temporary heat demand Future heat demand geothermal Residual heat biogas MW Load curve

16. Realised New (Yburg-II, existing real estate!!) Districtheating: connections Gecontracted (Parkstad, Noord / Houthavens, ZBE)

17. WPW Vision: busines Task –delivering –Increasing sustainability; –Growth network Real estate owners Vision: affordabel en sustainable real estate Tasks : –Isolate building –Sustainable energy –connections Municipality Vision: sustainable heat and cold, with central and decentralised sources Task: making preconditions DEAL: Growth and continuous sustainability (RAS) Public / private partnership (ROI) Policy (“heat unluss”, climate neutral building,, heat cold maps) Tarifs connections
