The “Regulation energy” graph shows the average of regulation energy minute values obtained as a result of the activation of all ancillary services (AnS) categories and procurement from the balancing market (BM) and abroad (either purchased or received as emergency assistance). A preliminary estimate of the level and direction (negative or positive) of system imbalance can be made based on these values (the activation of positive AnS is required to correct negative system imbalance). The data displayed serves only for preliminary information; ČEPS is not responsible for any damage incurred by the use of the values shown in the graph. Official system imbalance levels are available on the OTE (the electricity and gas market operator) website.

Displayed data define average minute power in MW. For “Hour” aggregation, average power is equal to energy in MWh.
