Risk assessment of a solar attack according to ISO 31000 standard

Energy supply still remains the greatest challenge for many of Eastern European countries and their economy. In post-soviet and ex-Yugoslavia countries even now exist a system where some of power plants relies on high voltage (HV) and medium voltage (MV) power grids in process of distribution of electric energy (EE) to final consumers. This heritage makes them vulnerable to solar storms due to HV power transformers are especially sensitive to geomagnetic induced current (GIC). The acquisition of electrical power infrastructure could put the electrical infrastructure out of service from a couple of months to a year or more. Losing the source of income for ordinary families is the primary hazard of a long power outage. Business continuity of industry and other critical infrastructures (CI) is the most important in this scenario, but it is a significant challenge for small businesses and enterprises as well. This paper introduces ISO 31000 standard to such scenario with primary goal of achieving resilience of the companies to such disaster as new method of vial response to vide scope of similar hazards.
