Serbia’s state power utility, Elektroprivreda Srbije (EPS), has invited bids for producing a preliminary feasibility study and conceptual design for a solar power plant on the ash disposal site of the Nikola Tesla A (TENT A) thermal power plant in Obrenovac.
The study should assess the feasibility and viability of the project, as well as the total solar potential of the site. The estimated value of the contract is RSD 14.91 million, and the deadline to submit bids is 23 January 2026.
The document must clearly define the proposed capacity of the planned solar power plant, the grid connection method, and the expected operating regime, according to the public call.
The capacity of the future solar power plant will be determined by the study
The project aims to expand EPS’ renewable energy capacities, reduce dependence on fossil fuels, and remediate the ash disposal site.
In July, EPS connected to the grid its first larger photovoltaic facility, the 10 MW Petka solar power plant. The plant is located in the Kostolac coal mining complex east of Belgrade, next to a 66 MW wind farm, which was put into trial operation in late November.
The design of the planned solar power plant at the TENT A ash disposal site should allow for integration with TENT’s existing safety and SCADA systems, while energy stability should be ensured through backup power sources, including solar panels with battery storage and/or an uninterruptible power supply (UPS) system.
The project should envisage battery energy storage
The photovoltaic panels should have a minimum power of 600 Wp, a minimum efficiency of 24%, and guaranteed production over 30 years of operation, while the efficiency of the inverters must be around 98% by European standards.
The part of the TENT A ash disposal site allocated for the solar power plant is slated for closure, and its usable area is about 67.2 hectares. The exact usable area will be determined following the completion of the study.
The selected bidder will be required to complete the task within six months of receiving all necessary documentation from EPS.
