The article describes the research direction of situational awareness in the cyber environment on energy facilities. A model based on a Bayesian Belief Network and a numerical method for determining cyber situational awareness are proposed to increase awareness of the cyber environment state on such facilities. The model is based on causal relationships between the vulnerabilities of the local area network and possible cyber threats, presented in the form of vectors of penetration into the network, vectors of the development of cyber attacks and attack vectors on the target asset, combined in scenarios. The work focuses on scenarios, the consequences of which can be regarded as extreme situations in the energy sector caused by cyber threats
