Overview • Status Quo: Renewable energy act • Concept of renewable trading platform
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. • realisation: physical balancing by TSO
TSO TSO Renewable energy act (EEG) - delivery of renewable energy to customers Distribution Network EEG-energy is passed on from the producers to the final customers. Payment (feed in tariffs) are passed on as well. EEG-Quota Sales Company EEG Plant (e.g. Wind Park) Final Customer
e.on Vattenfall Europe RWE EnBW Installed wind power & energy consumption • TSO in the north with high wind energy penetration
e.on Vattenfall Europe RWE EnBW Installed wind power & energy consumption • TSO in the north with high wind energy penetration
e.on Vattenfall Europe RWE EnBW Physical distribition of wind power between TSO`s • Energy is passed from E.on and Vattenfall grids towards EnBW and RWE-grids • Quarter-hourly exchange based on upscaled productions of representative wind-farms
e.on Vattenfall Europe RWE EnBW Physical distribition of wind power between TSO`s • Smoothing effect of wind power forecast error and load forecast error
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
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. „Grid operator are obliged to take, but the wind park owner is not obliged to give“

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.
Supply information • Include availabity • Pooling
Price information Trading platforms: • Power exange (EEX) • OTC • Forecast of price
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
Standard products for the energy market • Generate products is a challange Wind Power Peak Base
Standard products for the energy market • Consideration of all uncertainties Combined Uncertainty Wind Power Prediction Contracts
Which topics a trading tool should cover ? • Easy to access via internet: multiple user like trader, wind power maintenance, wind power operator • User dependend settings • All information together • Historic data available
