following procedure: Daily radiation data from the PV-GIS 2 (calculated as<br />
average <strong>for</strong> Austria from the easternmost, westernmost, northernmost <strong>an</strong>d<br />
southernmost point in Austria) are multiplied with the given average efficiency <strong>of</strong><br />
the modules <strong>an</strong>d multiplied with the given data on used area <strong>for</strong> PV from the<br />
feasibility study.<br />
4. Comparison<br />
In the fourth step, the dem<strong>an</strong>d <strong>an</strong>d <strong>supply</strong> curves are compared to derive daily<br />
<strong>an</strong>d <strong>an</strong>nual storage dem<strong>an</strong>d.<br />
5. Final assessment<br />
<strong>The</strong> last step compares the capacity <strong>for</strong> 2050 <strong>of</strong> Pumped Hydroelectric Storage<br />
with the total dem<strong>an</strong>d <strong>of</strong> <strong>electricity</strong> storage, to define how much storage capacity<br />
has to be gained additionally.<br />
