The project involves the connection of a distribution system, integrated with energy storage systems with a total installed capacity of 240 MW (charging and discharging), to the transmission grid.

In accordance with the grid connection conditions issued by Polskie Sieci Elektroenergetyczne S.A. (PSE S.A.), the investment is planned for implementation at a 400 kV voltage level, with the connection point located at the 400/220 kV Joachimów substation (Busbar Bridge in the 220 kV switchgear).

The earliest date for ensuring readiness for voltage supply has been set for June 2032, assuming the grid connection agreement is concluded in May 2026. This date may be subject to change during the negotiation of the grid connection agreement's terms and depending on the Operator's schedule for grid infrastructure investments.

The estimated connection fee, determined based on the connection conditions, amounts to 22,692,666.67 PLN net + VAT, with the possibility of update during the conclusion of the connection agreement.
