EPS IS LOOKING FOR CONTRACTORS TO BUILD SOLAR POWER PLANT NEAR KOSTOLAC

The public company Elektroprivreda Srbije (EPS) plans to build a solar power plant within the tailings dump from the Ćirikovac surface mine. The future Petka solar power plant is located on the left side of the Pozarevac-Kostolac road, and EPS has announced a tender for construction.

The Petka site is an external tailings dump from the Ćirikovac surface mine. The landfill has a maximum length of 2.2 km, a width of 1.2 km and a maximum height of 60 m. The landfill is formed in the form of floors, conical slopes of different widths and heights.

The regional road P-103 passes nearby. Based on the available areas and the relief of the site, the areas on which the solar panels will be placed were selected. According to the optimal inverter configuration, 17,100 panels can be installed at the location in question. Panels with a power of 650 W and an efficiency of 20.9% were selected.

The fixed position of the panel was adopted. It is not planned to manually adjust the inclination of the panels during the year, depending on the season, but it has been adopted to place the panels at an angle of 20 ° in relation to the horizontal.

Solar panels are placed in rows of different lengths, with one row formed by two rows of panels placed vertically. The distance between the rows is 4.5 m. The panels are placed at an angle of 20⁰.

The solution is the application of inverters connected to a single power of 100 kW, with a distributed layout of 10 transformer stations with transformers of a single power of 1 MVA, with LV distribution and construction of a 35 kV switchyard to connect the power plant to the distribution network. Inverters and transformers are distributed over the surface of the power plant, and the 35 kV switchyard is located in one building.

The use of 10 dry transformers with a single power of 1 MVA with a transformation coefficient of 35 / 0.4 kV is envisaged. Dry transformers are about 35% more expensive than oil ones, but they do not have a negative impact on the environment, so there is no need for an oil pit and problems with storing transformer oil.

The deadline for submitting bids is February 8, 2022, and see more details HERE.
