Electricity networks in Finland are subject to adverse winter weather, particularly a combination of heavy snowfall with strong winds, causing electricity outages especially in the rural areas. The severe consequences of such events require that electricity distributors and the entire network of stakeholders establish a proactive risk management for achieving enhanced situational awareness during adverse weather events, efficient and effective recovering after electricity outage as well as improved preparedness against future events. This paper shows how a risk assessment performed with an Action Error Analysis (AEA) were conducted in order to enhance the resilience of electricity networks against adverse winter weather. This also encompassed an assessment of co-operation and communication structures about such risks. Adverse winter weather that took place in Pirkanmaa, in South-West Finland in November 2015, serves as a case study and laboratory for the assessments. The results of the AEA underscore the importance of co-operation and communication-related challenges that electricity distributors, rescue authorities and municipalities face in maintaining and obtaining a high level of resilience of electricity networks during and after heavy snowfalls. Against this background, novel ways and measures related to co-operation and communication of stakeholders to improve the resilience of electricity networks against future events are discussed.
