Pricing Multiple Interruptible-Swing Contracts

In this article we price a multiple-interruptible contract for the electricity market in England and Wales under a mean-reverting jump-diffusion model with seasonality. We do so by combining forward contracts with a swing option which can be exercised a pre-specified number of times. We price this swing option by means of an extension of the Least-Squares Monte Carlo methodology for American options. We additionally compute the lower and upper bounds for this contract. For the computation of the lower bound we provide a semi-analytical formula which reduces greatly the required computational time.
