This paper will show how, in the conditions of the Covid-19 pandemic, the laboratory hours could be continued, without the physical presence of the students in the classrooms. The present paper deals with an electricity market software package developed for educational purposes. The discussion will be carried out for Electricity Market applications, but the principles have been applied for other disciplines, such as Energy Optimization Techniques. The central element of this approach is represented by the provision to the students for the remote work of packages of specialized software tools created for their training.
