In the recent years the runaway electrons have been intensively investigated at the COMPASS tokamak. It has proved to be a suitable experimental device for runaway electrons studies due to its safe operation concerning the presence of runaway electron beams and a set of diagnostics, which is useful for runaway investigation. The future runaway experimental campaigns at the COMPASS tokamak will be dedicated to investigation of interaction of runaway electrons with solid state pellets. In order to achieve this goal the solid state pellet injector will be moved from ASDEX Upgrade tokamak and implemented into tokamak COMPASS environment. This contribution reports on future experimental plans and discusses physics goals, which could be accomplished. The experiments will be mainly focused on generation and also on the possible mitigation of runaway electrons beams.
