Abstract: Starting from a basic Unit Commitment problem as published in [3], we develop a fully functional, running

implementation for FICO Xpress-Mosel, useable in power market modeling. The constraints of the model are

discussed in detail and solutions to implementation problems are presented. We also provide guidelines on

how to handle data input (from both, databases and Excel), as well as data output (to Excel).
