Status quo: renewable energy act
Fixed tarif: §5 (1) Netzbetreiber sind verpflichtet, Strom, der in Anlagen gewonnen wird, die ausschließlich
Erneuerbare Energien einsetzen nach §6 bis 12 zu vergüten.
Preference integration : §4 (1) Netzbetreiber sind verpflichtet, Anlagen zur Erzeugung von Strom aus Erneuerbaren
Energien vorrangig an ihr Netz anzuschließen und den gesamten aus diesen Anlagen angebotenen Strom aus Erneuerbaren Energien vorrangig abzunehmen.

Future : integration in the market has to be done
Fixed tarif system is the best for the beginning of integraton of wind power, ...
but with increasing share of wind power it has to be integrated in the power market.
What has to be considered:• Political framework• Development of methods and software for pratical realisation
![Page 10: Dr. Ulrich Focken European Wind Energy Conference Milan,09. May 2007](https://reader033.vdocuments.site/reader033/viewer/2022051620/56813127550346895d979a6c/html5/thumbnails/10.jpg)
Political Framework: Status Quo
Fixed tarif: §5 (1) Netzbetreiber sind verpflichtet, Strom, der in Anlagen gewonnen wird, die ausschließlich Erneuerbare Energien einsetzen nach §6 bis 12 zu vergüten.
Preference integration: §4 (1) Netzbetreiber sind verpflichtet, Anlagen zur Erzeugung von Strom aus Erneuerbaren Energien vorrangig an ihr Netz anzuschließen und den gesamten aus diesen Anlagen angebotenen Strom aus Erneuerbaren Energien vorrangig abzunehmen.

What is special to trade wind power ?
Power trading is for over 10 year daily business, but ...
Convertional power plants: The power plant is scheduled to sold energy.
Renewables: Trading the power which is predicted.

Risk assessment
Price risk
known problem in the energy market
Volume risk
deviation of schedule due to prediction error
How to deal with forecast errors:
balancing power
physical adjustment with conventional power plants
demand site management

Smoothing helps a lot
– Error decrease with
increase of regionsize
– Regional smoothing
depend only on regions
size, not on number of sites
– Error is reduced in
germany to 42 % compared
to single forecast

Start trading in germany with WPD / EWE
• 1.6 GW inst. Capacity distributed over whole germany
• Predictions are available for each single wind farm• A company to trade wind power will be estabished by EWE and WPD
So - methods and software to trade wind energy are available !
