Implementing a Unit Commitment Power Market Model in FICO Xpress-Mosel

Starting from a basic Unit Commitment problem as published in [Carri\'on2006], we develop a fully functional, running implementation for Xpress Mosel, useable in power market modeling. The constraints of the model are discussed in details and solutions to left open implementation problems are presented, guidelines on how to handle data input (from both, databases and Excel), as well as data output (to Excel) are given.
