1 Trias Westland geothermal exploration Hans Veldkamp (TNO Geological Survey of the Netherlands) on behalf of Floris Veeger (Trias Westland)

2 Presentation outline Background of the project Making the project a technical success Making the project a public success Making the project a financial success Current status With exploitation of Triassic aquifer Westland can become self-sufficient in its renewable (heat) demand

3 Current status of geothermal in the Netherlands

4 Introduction: municipality Westland

5 Heat demand Heat demand glasshouse industry Approximately 28 PJ Equivalent of 1,000,000 houses Decrease 25% Heat demand PJ What if geothermal provides heat demand Lower Cretaceous (15 x 17,5 MW) 6,61 PJ Triassic (15 x 30 MW) 11,34 PJ Total geothermal contibution 18 PJ 55% of total energy demand in Netherlands is heat

8 NIMBY: could you please move that doublet to my neighbours backyard? Quote from Larry Susskind (MIT) National Public Radio featured a story this week about growing opposition to renewable energy facilities, particularly wind power. Wind advocates were asked how they might overcome such local opposition -- dubbed the NIMBY syndrome -- in the future. The spokesperson said, "We've got to get in there earlier and educate people." Wrong! How arrogant! You think people are opposed because they don't understand? No, they're opposed because the "costs" and "impacts" ON THEM are likely to outweigh the likely benefits TO THEM. The only way to overcome the NIMBY syndrome, regardless of the type of facility, is to make sure that the overwhelming majority of people in the area believe that the benefits TO THEM if the facility is built will outweigh the costs and impacts THEY are likely to experience.

9 Avoiding NIMBY around controversial technologies: It is all about balance between (perceived) costs and benefits

11 Project: The Cooperation Model Project is financed by 3 parties No clients but owners Royal Flora Holland 10% Capturam 45% Based on true costs Project success will result in lower tariffs After break-even Participants get full ownership HVC 45% Participants 100% Heat network can be used to optimise sustainable heat supply

12 Project: The Cooperation Glasshouse owners Extending current heating network Towards sustainable heat supply Independency from gas supply/prices HVC WI FH Cooperation TRIAS WESTLAND Power of control Return on equity 1. Participant signs a contract for X amount of heat (in MW) 2. Capacity fee based cost price (with a ceiling) 3. Participants can trade excess heat through trading platform 4. Profits of maximum use of full load hours go to participants 5. Further cooling (below 35 C) profits the participants
