In the serene region near the town of Ub, there is a company that has nurtured a tradition and dedication to agriculture for generations – Stočar LSB d.o.o.
The family story has been passed down for generations, culminating in the formal establishment of the company in 1991, deeply rooted in the land and traditions of the Leontijević family.
Today, the estate cultivates as much as 1,400 hectares of arable land, of which 1,000 hectares are under corn and 400 under wheat – all dedicated to feeding livestock exclusively with crops grown on their fields. This closed-loop production system, from field to table, is the foundation of the trust consumers place in their products.
The grains are stored in silos with a capacity of 30,000 tons, while bulky feed is stored directly on the farms. Within the silo complex, there is a mixing facility for preparing complete feed mixtures for cattle.
At the heart of this story are two farms – Farm Orašac, with a capacity of 2,000 head of cattle, and Farm Radobić, which currently accommodates 1,000 head but is undergoing reconstruction that will increase its capacity by an additional 500 head.
However, the company’s self-sustainability is also reflected in its electricity production. At the Radobić farm, a 1 MW biogas plant is in its final phase of construction. It will be powered by organic waste from farms and silos.

The company MT-KOMEX, specialized in building solar power plants and experienced in energy infrastructure, has had a long-standing collaboration with the Stočar LSB, starting with the installation of two rooftop solar power plants. The first plant, with a capacity of 40 kW, is registered as a prosumer, meaning that part of the electricity is used on-site, while the surplus is fed into the grid. This power plant currently meets approximately 80 percent of the facility’s energy needs. The second power plant, with a capacity of 350 kW, is also installed on the company’s rooftops.
Following the successful implementation of these projects and the high-quality technical support, the company once again turned to MT-KOMEX to carry out energy connection works for the biogas plant under construction at the Radobić farm, which will have an installed capacity of 1 MW.
During the final construction phase of the biogas plant, MT-KOMEX completed the following key electrical infrastructure works. Two transformer substations were built: the first is intended for supplying the farm’s and plant’s internal energy needs. It contains the main distribution switchgear for the entire complex, which will be transferred to Elektrodistribucija’s ownership upon completion of the connection. The second substation, with an installed capacity of 1,600 kVA, is designed as a grid connection point for the biogas power plant. It includes complete low-voltage equipment and a medium-voltage switchgear manufactured by Schneider Electric. This substation also houses a step-up transformer, which raises the voltage from low (the output of the cogeneration unit) to medium (10 kV), ensuring the necessary conditions for grid connection. This solution by MT-KOMEX enables efficient use and grid integration of electricity produced from biogas, closing the energy loop and further enhancing the sustainability of the entire Stočar LSB system.
