SIV Procurement for the following day
Internal Security Sales (SiV):
Control area internal security sales (SiV) are measures taken in the light of the risk that the (n-1) security is violated due to overload on the interconnection lines. Energy volumes are purchased on the power exchange and subsequently transferred to a balance group within the control area, where feed-in is reduced by the same volume. Control area internal security sales (SiV) will be published in the afternoon of the trading day, if there are any trades for the following day.
