Construction of PPPsChelnik 1

The built power plant transforms solar radiation into electricity through polycrystalline photovoltaic modules generating direct current and voltage. The resulting voltage is transformed into an alternating voltage by three-phase invertors, then increased to 20kV and the generated electricity is supplied to the medium-voltage distribution grid of the country.

According to the project, a concrete complete indoor distribution system (BKZRU 20kV), with three inputs, was installed on the site of the power plant. A transformer 630 kVА, as well as such 100 kVA, was installed in it. The MV distribution system was equipped with a switchgear (KRU) 20 kV, 630 А, 16 kА.

Along the property perimeter, a wire fence was built, lighting columns were installed, access control system and video surveillance were built.

Project value: BGN 16 million
