240 BESS MW OSDn - PSE - 110kV - Zachodniopomorskie

Grid Connection Project for the Distribution System (DSO) – BESS 240 MW / 240 MW

Connection Voltage: 400 kV

Energy storage capacity: 240 MW (grid injection) / 240 MW (grid withdrawal)

Planned energization date: June 2034

Estimated grid connection fee: PLN 25,565,500.00 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 400 kV voltage level, with the connection point at the 400/220/110 kV Dunowo substation (Busbar in the 400 kV switchgear).

The earliest date for ensuring energization has been set for June 2034, assuming the grid connection agreement is concluded in June 2026. This date may change during the negotiation of the grid connection agreement's terms and depending on the Operator's schedule for network investment implementation.

The estimated connection fee, determined based on the connection conditions, amounts to 25,565,500.00 PLN net + VAT, with the possibility of an update during the conclusion of the connection agreement.
