The dependence of agriculture and the food production sector on electricity leads to the risk of losing an entire crop as a result of a disruption in the supply of electricity from the grid. To ensure the safety and continuity of food production, it is necessary to use an emergency power supply system that will maintain proper growing conditions in case of periodic power shortages. This emergency power system can be based on energy from renewable sources. This paper presents the possibility of using a photovoltaic system with an electricity storage facility as an energy backup for vegetable sprouts cultivation. Based on the simulation model of the sprout production plant developed with the Flownex Simulation Environment software, its maximum electricity demand was determined, which was 25.3 kWe. The simulation results and weather data for a typical meteorological year were used to select the size of the photovoltaic installation components and to develop its simulation model. After commissioning the backup power installation, the results of the simulations were compared with the data obtained from the real system. The total annual energy production was 41.9 MWh higher than the modelling results. The study confirmed the feasibility of the emergency power supply of the crop of vegetable sprouts using a photovoltaic farm and an energy storage facility. Moreover, the backup system may be successfully used within periods between disruption of net electricity supply, and allows form significant decrease of installation operational costs.
