The project involves connecting a distribution system—integrated with energy storage facilities with a total installed capacity—to the transmission grid, with a limit of 49 MW on power fed into the grid and 240 MW on power drawn from it.

In accordance with the connection terms issued by Polskie Sieci Elektroenergetyczne S.A. (PSE S.A.), the project is planned to be implemented at the 220 kV voltage level, with the connection point located at the 400/220/110 kV Polkowice substation (Rail Bridge in the 220 kV switchyard).
