The development and implementation of new correlation-statistical models for the operational assessment of technospheric risks arising from the impact of space weather on power electric systems operating within the boundaries of the auroral oval is currently an urgent research problem with a pronounced applied nature. Such models demonstrate the highest practical significance in polar subregions with a low density of coverage by reliable and credible sources of geomagnetic data, i. e., in fact, the overwhelming territory of the Arctic zone of the Russian Federation (AZRF).

The paper is concerned with a new approach, which is proposed to the non-hardware assessment of the level of geoinduced currents (GIC) in the power electric systems of the AZRF, which is based on correlation-statistical modeling of the GIC level according to the observation of auroras as an accessible natural indicator of space weather state.
