PSE Launches Unilateral Monthly Capacity Auction for Poland-Ukraine Radial Interconnection (November 2026)

PSE S.A., acting as the Auction Office, began on 14 October 2026 the process of a unilateral monthly capacity auction for transmission capacity on the radial interconnection between PSE S.A. and NEK Ukrenergo, covering the reservation period 1 November 2026 – 30 November 2026, under the published '2026 Auction Rules' (Zasady Przetargów).

This establishes the concrete operational timeline and procedural steps (registration, capacity publication, bid submission, results publication, invoicing) by which market participants obtain cross-border transmission capacity on the Poland-Ukraine interconnector, directly affecting access to and pricing of this limited non-EU interconnection capacity.

The communiqué documents the recurring execution of a bilateral, non-EU-regulation capacity allocation mechanism (distinct from EU-harmonised CACM auctions) governing a radial interconnector with Ukraine. As a unilateral PSE-run process (not a joint PSE-Ukrenergo auction platform), it reflects the unique governance arrangement needed for interconnection with a non-EU, non-synchronized system. Tracking the monthly cadence, deadlines and published rules is important for understanding how Poland-Ukraine cross-border capacity is allocated, which affects regional security of supply, price convergence at the border, and participant access, especially amid wartime grid conditions in Ukraine.
