Electricity spot price modelling with a view towards extreme spike risk

Sums of Levy-driven Ornstein-Uhlenbeck processes are appropriate for modelling electricity spot price data. In this paper we present a new estimation method with particular emphasis on capturing the high peaks, which is one of the stylized features of such data. After introducing our method we show it at work for the EEX Phelix Base electricity price index. We also present a small simulation study to demonstrate the performance of our estimation procedure.Financial mathematics, Extreme value theory, Energy derivatives, Energy markets,
