What is Spatial Energy Planning? Heat is local Focus on a municipality/region and its heat supply and demand Identify optimal strategies for the future Link local renewable heat supply with demand

What is Spatial Energy Planning? First step: Know the local heat demand

What is Spatial Energy Planning? Second step: Know potential (local) heat sources – renewable and waste heat

What is Spatial Energy Planning? Conclusion: Link heat demand with supply – design optimal strategies and identify specific opportunities and measures

Spatial Energy Planning: Local Heat Demand Density of heat demand How much heat is used where? Which customers: Residential? Industry? What temperature levels? What is the future heat demand?  Crucial for rentability of district heating

Spatial Energy Planning: Local Heat Demand Existing energy infrastructure What is today’s situation of heat supply? Existing networks for district heating and gas distribution

Spatial Energy Planning: Potential Heat Supply Waste Heat Opportunity: District heating Spatial Energy Planning: Identify local sources of waste heat Are they a suitable source for district heating? What is the heat demand in their proximity

Spatial Energy Planning: Potential Heat Supply Waste Heat Opportunity: District heating Spatial Energy Planning: Identify local sources of waste heat Are they a suitable source for district heating? What is the heat demand in their proximity

Spatial Energy Planning: Potential Heat Supply Ambient Heat Opportunity: Use ambient heat for single buildings or in district heating Spatial Energy Planning: Map possible sources of ambient heat: geothermal, ground water, ambient air, rivers and lakes Identify areas where use of ambient heat is feasible

Opportunities and Measures identified in Swiss Energy Plans

City of Bern: “Energiezentrale Forsthaus” Strategic Coordination of a City’s Heat Supply

City of Bern: “Energiezentrale Forsthaus” Strategic Coordination of a City’s Heat Supply

City of Zofingen: Heat supply from the new Hospital Coordination of a large building project with the need of a new energy source in the old town of Zofingen

Municipality of Koeniz: Heat supply for a new district Coordinating the heat supply for a newly developed district

Municipality of Riggisberg: Securing local heat supply Negotiating supply and demand for district heating in a small Swiss village

Region of Goms: Use of regional Biogas Use of local renewable resources and strengthening of the local economy in a region in the Swiss Alps

Why Spatial Energy Planning? Opportunities and benefits Identify and coordinate optimal strategies for the future heat supply Seize opportunities and identify further measures: coordinate building projects with developing energy infrastructure Improve rentability of district heating and energy infrastructure in general Create value for the local economy and increase security of supply Achieve environmental benefits: greenhouse gas emissions and pollution
