Energy security and implicitly the regional energy architecture composed of critical energy infrastructures (power substations and overhead lines at 400 kV), can undergo various mutations and transformations caused by a possible syncope in the extraction, transport and exploitation of energy resources and energy, due to energy dynamism. The vulnerability of these critical energy infrastructures generates a number of risks and threats to them, thus endangering societal life, creating malfunctions and generating extreme damage to the state. Critical energy infrastructures thus become indispensable to society, without which the state and its mechanisms cannot function and ensure societal well-being, and their protection becomes a major national and European objective, prompting representatives of the member states of the European Union to take action to identify and manage any risk or threat. In the face of the vulnerabilities, threats and risks Romania faces in the new dynamic, turbulent and unpredictable geopolitical context of global, regional and Euro-Atlantic security, amid the military and health crisis and amplified by the global energy crisis manifested by the unfounded and unexpected increase in energy price, the Romanian state should have a strategy for strengthening the resilience of critical energy infrastructures, based on predictability, flexibility, continuity, adaptability and resilience.

Energy security, which is defined by the availability at all times of energy in all its forms, in sufficient quantities and at affordable prices, without unacceptable or irreversible environmental impact, must be the central pillar of the strategic analysis of the national security of the Republic of Moldova, in the context of accession and integration to the European Union. Easy access to energy resources is an essential condition for the security and well-being of Moldovan individuals, businesses and communities. Given the status of the Republic of Moldova as an acceding state to the European Union, which is at the forefront of defense of the entire Euro-Atlantic space against the offensive of the hostile interests of the Russian Federation, the region has become the hottest geopolitical, geoeconomic and geostrategic space for direct confrontation of the interests of the West and East, with a huge potential for escalation to a military conflict. Against this background, the preferred means of threat of the Russian Federation proves to be the energy weapon, used both for the promotion of major economic interests, as well as as as an instrument of influence and political blackmail. Therefore, energy is no longer only a factor of the equation of economic power of the Moldovan state, but also an element of political influence and control, with reflections in the military capabilities. The authors want to analyze the state of energy security regarding the state of energy resources and electricity.

The aim of occupational health and safety in the context of industrial safety is to provide the national industry with a proper operation state, an ergonomic, optimal and healthy work environment, safe workers and workplaces, safety of industrial processes, to limit and mitigate any unforeseen situation generated by events which might negatively affect the occupational health and safety level. The current paper approaches the risk assessment in terms of occupational health and safety within a cross-border 400/220 kV power substation interconnected to the European power grid, identified and assigned as European critical infrastructure. The assessment is carried out using the INCDPM Bucharest method, in order to establish the risk/safety levels in a quantitative manner, based on a systemic analysis and on the assessment of risks of accidents and professional diseases. The application of the method ends in a workplace assessment sheet which comprises the global risk level of the power substation and which sets the grounds for the plan for preventing accidents and professional diseases within the analysed power substation.

In increasing occurrence for the cases of energetic collapse around worldwide, manifested by the lack of finite primary energetic resources (oil, gas, coal and uranium) or electricity to the final consumers, and even the desiring for the world’s major energy powers in owning and controlling, the entire chain of global energy in order to use primary energetic resources or electricity as a possible energetic tool or pressure tool in the context of blackmail and profitability, makes this thesis of a great importance and relevance. By the lack of supplying the primary energy or electricity to final consumers leads to the crises that cause societal disproportions causing extreme damage to the safety of citizens, industry, the national economy and thus national security, because all areas of a state economy depend on primary energetic resources or electricity. In this context, the energy security of a state becomes an important pillar of national, regional and international security, bringing safety, stability and well-being to the final consumers for electricity usage.
