GIC recordings from auroral Vykhodnoy (VKH) and subauroral Kondopoga (KND) sub-stations together with data from near-by magnetometers have been examined. Extreme bursts of GIС are mainly observed in the pre-midnight and post-midnight magnetic local time sectors during substorms. From 92 extreme events (GIC >20 A) at sub-station VKH 53.2% were caused by CME magnetic storms, 34.8% occurred during CIR storms, 3.3% are caused by SC/SI and 8.7% occurred during substorms without magnetic storm. From 31 extreme events (GIC >5 A) at sub-station KND 80.6% were observed during CME storms, 12.9% occurred during CIR storms, and 6.5% took place without a magnetic storm. Therefore, for the prediction of the space weather impact on power lines, both CME and CIR storms and even non-storm intervals should be taken into account. Maximal GIC magnitude grows on average with an increase of geomagnetic field variability dB/dt, but for many events the actual GIC is less than the maximal possible value due to a localized nature of magnetic field disturbance. There is no clear linear dependence of the GIC amplitude on the parameters of the interplanetary medium (V, Es, ε) and geomagnetic indices (IE, AE, SYM-H), which indicates the difficulty of predicting GICs in particular technological system. On average, with an increase of the intensity of magnetic storm (SYM-H), substorm (IE index), higher GIC values are registered.
