Izgrev, Elhovo municipality, Yambol region.

Characteristics of the investment proposal:

1. Summary of the proposal:
The subject of the investment intention is the implementation of a combined project consisting of the installation of a local electrical energy storage facility at a photovoltaic power plant – FTPP with an installed capacity of 0.3996 MWp and a maximum inverter AC capacity of 0.4 MW in PI with identifier 32576.33.48 , UPI I-048, m. 33, “Bey Bair” street, h-shte s. Izgrev, Elhovo municipality, Yambol region” and AC cables for connection to an existing substation of the FTPP, according to the conditions for application under procedure BG-RRP-4.032 “Support of new capacities for the production of electricity from renewable sources and storage of electricity with an installed capacity of 200 kW to 2 MW” to the National Plan for Recovery and Sustainability of the Republic of Bulgaria, Component “Low Carbon Economy”
According to Art. 61c. (New – SG No. 11 of 2023) of the Energy Act “Electricity storage facility” is a facility within the power system in which energy is stored, with the exception of energy storage facilities for own consumption to producers or end customers, which does not transfer the stored electrical energy to the power transmission or distribution network of the Spatial Planning Act.
