The intraday electricity market is increasing its importance within the energy markets. This article introduces a case study, basing on real examples of the contribution electricity markets make to prevent and/or solve emergencies in electric system. The case study was conducted in four possible states on short-term markets – different variants of trading period lengths and intervals in which the system imbalance is evaluated. The outage of the biggest power plant´s unit in the transmission system was always considered, and together with the situation in the short-term markets, the impact on the operation and maintenance on a transmission system was evaluated from that point-of view, system imbalance, and necessity to activate necessary ancillary services by an operator.
