Case studies
Cities (adaptable at the regional level)
EIfER12
Energy & CO2 balance
Energy system: modeling energy flows, emissions and costs(all sectors, all energy vectors)
Erstein 2003 Alsace 1999 France 1999
Recommendations, action plan (energy efficiency, CO2 mitigation)
EIfER13
Case study: energy efficiency
Émissions 2003
Narbonne:
Transports = 52% of total emissions
Mainly motorways and main/secondary roads
Energy efficiency plan directly linked with the regional level (traffic & emissions models)
[ Same with industry ]
EIfER14
Local energy mix
Erstein:
Energy mix for public buildings
Option: wood-fired boiler room
Feasibility depending on resource parameters cities can not easily identify
> importance of regional resources studies
Contribution of the wood-fired boiler
(C02 emissions)

Biomass: GIS-based energy wood resource assessment in the northern Black Forest region (I)
Study area and partners
• Black Forest• 57% forest (mainly public)
Source: http://www.nordschwarzwald-region.de/
• The Forest State Administration (Landesforstverwaltung B.W.)• The regional planning authority (Regionalverband NSW)• University of Karlsruhe (EIfER, IPF)• EDF
EIfER18
Biomass: GIS-based energy wood resource assessment in the northern Black Forest region (II)
Diameter of the tree (BHD)
Production costs rise exponentially with smaller tree diameters
Slope
Applicability of highly automated machines is limited to max. 30% slope
Tree species
Wood energetic value depends on the tree species
Transport distances
Wood chip production chain and related cost factors
EIfER19
Biomass: GIS-based energy wood resource assessment in the northern Black Forest region (III)
Model the theoretical potential
Model costs for wood chip production for each forest stand
Model transport costs
Layers: - road network's nodes- forest plots- digital terrain model
Methodology
EIfER20
Biomass: GIS-based energy wood resource assessment in the northern Black Forest region (IV)
Wood chip processing costs for each forest stand
Show all forest stands that offer more than x tons dry mass/ha and where mobilization costs is less than y €/m³
Supply curves for scenarios with respect to several parameters
Wood energy potential can be modeled as steady function of wood chip market price supply curves
Some results

Biogas: Optimized sitting of co-fermentation plants in Baden Württemberg
Total accumulated methane potential differentiated into distances
Applied road distances around the locations – restricted to the study region

• EIfER• BRGM Alsace• ADEME• ÉS
Potential for geothermal power production depends on :
- depth of the aquifer- temperature of the aquifer- thickness of the aquifer

• In practice, the accessible resource that can be extracted is only a part of the total resource.
• The ratio depends on the availability of fluids in the aquifers (expressed by the transmissivity of the aquifer) and the time during which the extraction can be economically carried out.

Conclusion (I)
Real world
Analysisof data
Decisionmaking
Data collection and
management
Strategic levelmulti-criteria
geographical analysis=
link between regional and local levels
A regional opportunity study (e.g. renewable energy resources) can provide realistic potentials and localization recommendations directly usable for local feasibility studies.
Every local detailed study can enrich the regional database.
EIfER28
Conclusion (II)
Energy planning at the regional level:
assessment of the potentials (RES, energy efficiency, …) using multi-
criteria geographical analyses
modeling of energy flows and impacts of scenarios (derived from
potentials)
Benefits:
facilitation of the implementation at the local level (feasibility information,
best practices)
improved orientation (modeling, prospective)
possible definition of precise regional targets (monitoring)
