One of the most important indicators that are used in the characterization and analysis of the processes of intensification of agriculture are indicators of the availability of agricultural enterprises with energy resources such as energy security and power supply capacity. The purpose of the work was to analyze the dynamics of indicators of energy security and power supply capacity of agricultural organizations in the Republic of Belarus. A number of important points and indicators characterizing the current state and potential of Belarusian agricultural production has been considered in the article. It has been established that over the past decade in agricultural organizations of the Republic there has been a decrease in the indicator of energy security by 15 %, and the power supply capacity of labour has increased more than 1,4 times during this time. On the overall efficiency of agricultural and livestock production, on the level of labour productivity in agricultural organizations, indicators of power supply capacity have a very significant and very often decisive impact. Under the conditions of the steady decline in the number of people employed in the agro-industrial complex, the increase in the volume of cultivated areas and, in general, with the increase in the physical volumes of products produced in crop production and animal husbandry, the role of energy-saturated machines, machinery, equipment and their rational use is repeatedly increasing. The requirements for productivity, functionality, efficiency, reliability of agricultural machinery, machines and aggregates are seriously increasing. Only the comprehensive and systematic technical and technological re-equipment of agricultural production, its saturation with high-tech, high-performance agricultural machines, complexes and equipment will be able to ensure the significant increase in labour productivity, minimize the expenditures of all types of material, fuel and energy resources and, as the result, maximize the fulfillment of tasks to preserve the country’s food security.
