240/110 BESS MW OSDn - PSE - 110kV - (Śląskie)

Distribution System Connection Project (DSO) – BESS 240 MW / 110 MW

Connection voltage: 110 kV

Energy storage capacity: 240 MW (grid injection) / 110 MW (grid consumption)

Planned energization date: December 2028

Estimated connection fee: 22,045,666.67 PLN net + VAT

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 110 kV voltage level, with the connection point located at the 400/220 kV Łośnice substation (Busbar Bridge in the 110 kV GIS switchgear).

The earliest energization date is set for December 2028, assuming the connection agreement is concluded in June 2026. This date may change during the negotiation of the connection agreement's terms and depending on the Operator's grid investment implementation schedule.

The estimated connection fee, determined based on the connection conditions, amounts to 22,045,666.67 PLN net + VAT, with the possibility of adjustment during the conclusion of the connection agreement.
