240/49 BESS MW OSDn - PSE - 110kV - Dolnośląskie

Distribution System Connection Project (OSDn) – BESS 49 MW / 240 MW

Connection Voltage: 220 kV

Energy storage capacity: 49 MW (grid injection) / 240 MW (grid withdrawal)

Planned energization date: December 2034

Estimated grid connection fee: PLN 22,692,666.67 net + VAT

The project involves the connection of a distribution system to the transmission network, integrated with energy storage systems of a total installed capacity, with the power injected into the grid limited to 49 MW and withdrawal to 240 MW.

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

The earliest date for ensuring energization readiness is set for December 2034, assuming the grid connection agreement is concluded in July 2026. This date may be subject to change during the negotiation of the grid connection agreement's terms and conditions, and depending on the Operator's network investment implementation schedule.

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