1. Merging energy management and spatial planning Case study: Delfzijl Anne-Lorène Vernay master thesis, august 2007

2. To generate heat Current situation Waste heat To generate heat Electricity To generate electricity

3. Energetic potentials: Possibilities to generate renewable energy from wind, water, biomass, ground (geothermal). large quantities of waste heat available  Diverse potentials in the area Political will: Province of Groningen shows an interest in implementing innovative ideas to improve energy use  Favorable political climate Why Delfzijl energetic potentials and political will

4. Hot spots of electricity consumption

5. Installed isolated windmills Projected and installed wind parks Potential osmosis plant Potential waste fired plant Potential micro biomass CHP Projected biomass incinerator Existing CHP Potential for geothermal energy Import of energy from the Eemshaven Existing railway Energy production and renewable energy potentials

6. Current heat demand the area (90°C used) Waste heat generated (average 40°C) Waste heat generated (average 32.5°C) Waste heat generated (average 30°C) Waste heat availability and heat demand

7. Potential developments Legend: Area link to the DH network Upgrading plant Simplified DH network Anaerobic fermentation installation Transport of biomass Residential areas linked to geothermal district heating Osmosis plant Greenhouses Implementation of renewable energy technologies Residential areas link to biogas micro CHP plant Zonneterp

8. Ideas for discussion Is this approach relevant when it comes to optimizing energy use? What is needed for implementation? Or what could slow down (or even prevent) implementation?
