Excess heat from energy-intensive industries is often suitable for use in district heating systems but is usually unutilized. A detailed overview of the potentials available in the EU is now provided by a database of the sEEnergies project. In Germany, 29 petajoules of excess heat from industrial sites could be used, which corresponds to the demand of more than half a million households. The information is available as maps and downloadable datasets.
In the study "Medium-term forecast of electricity supplied to final consumers in Germany in the calendar years 2016 to 2020" the Fraunhofer ISI determined the final consumption for 2016 across which the cost of refinancing renewable energies will be split in Germany.
study "Medium-term forecast of electricity
supplied to final consumers in Germany in the calendar years 2016 to 2020" the Fraunhofer ISI
determined the final consumption for 2016 across which the cost of refinancing
renewable energies will be split in Germany. The decline in final consumption
can be traced back to a drop in net electricity demand to about 512 TWh, which
is mainly due to efficiency improvements in electricity-based applications and
processes. There has also been a slight increase in self-generation to about 52
TWh, for example from installing PV systems in private households, which has
contributed to the decline in final consumption as well.
combination of these trends results in the final consumption for 2016 dropping
to 460 TWh compared to 2015. The privileged share of final consumption – the
part that only has to pay a reduced EEG surcharge – amounts to 104 TWh next
year. This means a non-privileged final consumption share of around 356 TWh, for
which the EEG surcharge has to be paid in full. The drop in the share of final
consumption subject to the full surcharge combined with a further cost increase
for expanding renewable energies results in the EEG surcharge rising to 6.354 cent
per kilowatt hour in 2016.
the final consumption subject to the EEG surcharge, the Fraunhofer ISI’s study
also estimated the associated cash flows. The surcharge payments of final
consumers (privileged and non-privileged) contribute 22.88 billion euros to
financing renewable energies.
surcharge finances the difference between the revenues from selling
EEG-financed power on the market and the payments made by transmission network
operators for power generated from renewable sources. This surcharge is paid by
the non-privileged and partially privileged end consumers of electricity. A
special equalization scheme regulates which consumers only have to pay a
limited EEG surcharge. The 2014 amendment of Germany’s Renewable Energy Sources
Act (EEG) has resulted in a much more complicated special equalization scheme, primarily
due to the introduction of various exceptions and hardship case regulations.
The Fraunhofer ISI‘s final consumption forecast was differentiated by the
various privilege categories in order to account properly for the different
rates of EEG surcharge.
