Utilities are forced to reduce fossil fuel consumption and ultimately to decarbonize its heat generation. The local operator is forced to pay penalties as their natural gas demand eceeds contractual agreements. Patch operation of fossil-fired boilers are highly cost intensive in contrary to steady operation. To cover all risks of Panĉevo district heating, the collaboration under the umbrella of the EBRD program ReDEWeB* between SOLID and the local utility led to a comprehensive evaluation for implementing a BigSolar system. The specific framework conditions and individual stakeholders’ needs were comprehensively evaluated. Different concept solutions were fed with a dynamicsimulation based sensitivity analysis by also consideringpotential available land nearby. BigSolar has shown to be integrated straight forward into the existing district heating supply system. The results show an attractive decarbonized option for a strategic renewable energy supply. In the next phase of the project SOLID proceeds with a detailed feasibility study as basis for starting the a detailed engineering process. As added value, BigSolar in Panĉevo has the potential to be a lighthouse project in Western Balkan countries leading to significant CO2-reduction in district heating. The customer received a tailor-made, feasible, competitive and green solution, which additionally reduces the variable OPEX of natural gas consumption. *Renewable District Energy in the Western Balkans

The installed heat storage, with a capacity of 165 m³, results in an overall efficiency increase via energy management.
Energetika Vransko, the local utility, wanted to increase their green energy supply to the district heating system. The signs were good – especially lucrative funding
