MAPPING THE TERRITORY OF MUNICIPALITY Bad Radkersburg

MAPPING THE TERRITORY OF MUNICIPALITY Bad Radkersburg
AUSTRIA
Introduction
By mapping different sites in Styria and using general instruments like irradiation maps
finally Bad Radkersburg was identified as a current potential spot to foster PVPPs. Following
the selection data criteria this example will be described as follows:
Data sources
The data sources for this case study come from representatives of the municipality of Bad
Radkersburg and of federal state government as well as specific data on photovoltaic come
from PVGIS homepage (http://re.jrc.ec.europa.eu/pvgis ).

Austria
JRC Radiation
PVGIS is a research tool but also a support for the policies of the solar resources assessment.
This tool was used to evaluate the photovoltaic performance of the territory of Bad
Radkersburg with following indicators:
The chosen technology for the modules was the crystalline silicon technology. The peak
power was set on 1kWp. The estimated system losses are generally calculated on a level of
14%. The model plant is free standing. For fixed installation was considered an inclination of
35° to optimize production throughout the year.
The plant configuration will be affected by a fixed annual value of radiation 1330 Wh/mq
which will produce annually 1010 kWh of electricity.
Performance of Grid-connected PV
The following tables sum up the PV performance of the given location.
Location: 46°41'13" North, 16°0'9" East, Elevation: 207 m a.s.l.,
Nominal power of the PV system: 1.0 kW (crystalline silicon)
Estimated losses due to temperature: 8.3% (using local ambient temperature)
Estimated loss due to angular reflectance effects: 2.9%
Other losses (cables, inverter etc.): 14.0%
Combined PV system losses: 23.4%
Fixed system: inclination=35°, orientation=0°

Recognition of marginal areas
By collecting information of potential marginal lands in wider region of East and South-WestStyria we set evaluation grid to identify first spots to be in line with future PVPPs. We
collected information about abandoned industrial areas, agricultural waste ground and specific
areas like landfills and potential of army barracks which will be changed in near future
Main reasons for the decision for potential example of Bad Radkersburg were as follows:
Close to usable road and voltage grid.
Potential space to enlarge PVPP in modularly.
Open-minded attitude of municipality regarding new renewable energy solutions.
Common interests of twin city in Slovenia just separated by river Mur, i.e. an additional
potential for common PVPPs.
In detail the municipality of Bad Radkersburg is interested in valorising areas that are no
longer in use as industrial property. The PV’s in Bloom Project represents therefore a good
opportunity to revalorise these areas. The municipality has identified so far one potential plot
for installing a PVPP in the future. It is situated in Laafeld which corresponds to the environs
of Bad Radkersburg in the federal state of Styria. The surface area of the plot (red marked) is
approximately 9899 sqm.
Owner of the area is the municipality of Bad Radkersburg with “Radkersburg Umgebung”
limited partnership. The building density goes from 0,2 to 1,5. The plot has a sea level of 209
m. Near the area there are no multi-storey buildings so that a complete sun radiation during
the day can be guaranteed. Approximately 800 m to the east of this plot there is a electrical
power substation from STEWAG- steg in which occasionally electrical power can be feeded
in.

Verification of technical and functional criteria and localisation
The technical criteria required for the functional implementation of the project "PVs in
Bloom" are partly fulfilled:
- Exposure to radiation is very good
- The surface is flat
- The area is easily accessible thanks to the roadways and close to the electricity
distribution network.
- The surface area is 9899 mq, which should be enough for a PV plant.
