Abstract: This thesis has 8 chapters. The chapter 1 is an introduction to the issues encountered in the energy market : low frequency trading, high transaction costs, spread option pricing. The chapter 2 studies the hedging error convergence of a call option in the Bachelier model, for proportional transaction costs (Leland-Lott's model) and when the intervention frequency becomes infinite. We prove that this error is bounded by a random variable proportional to the convergence rate. However, the proof of convergence in probability requires some restrictive regularities on the sensitivities. The following chapters avoid these difficulties by studying the almost sure convergence. The chapter 3 develop new tools for the almost sure convergenc...
