System power balance reflects the net volume of all cross-border energy flows.
Positive net physical flows reflect energy withdrawals from the Estonian power system through cross-border lines and negative net physical flows reflect energy injections to the Estonian power system through cross-border power lines.
System AC (alternating current) balance reflects net energy flows with Latvia and Russia with whom the Estonian power system is connected through AC lines.
Planned system balances for next day shall be published at 16:00.
