Lack of competition – Open Access for everyone?
Theory: since 1998 open access for all network users in former Western Germany
Practice: many obstacles remain for many network users on low network levels like: few players with a lot of market
power,rather high prices for consumers remain, lack of real competition,open access

The Leipzig Power Exchange – Trade Data (II) – Anomalies
in December 2001 the „market-clearing-price“ reached a peak with 1000 Euro/MWh
the average weekly price moved to 50 Euro/MWh
‚prices are economically not logical nor explainable‘ (MVV)
problem: data about production, network problems not available to all traders
Conclusions considering Prices (I)
• Volatility seen in Power Prices is exremely high and unprecedented in other Commodity Markets • Prices vary substantially by time of day, week or year• Positive and Negative price „spikes“ can be observed• Frequency, Magnitude and complexity of Fluctuations also unique in commodity markets
Behaviour of prices suggests challenges associated with modelling these prices, e.g.
Conclusions considering Prices (II)
• Prices follow similar daily, weekly and annual patterns• Even the price volatility follows certain patterns, price volatility is strongly correlated with price levels • Basic relationships between power prices at different geographic locations show e.g. similar volatility
However.....
.....the challenge is to build models that capture this complex behaviour of prices
