What changed

PSE announced that pre-auctions for the additional capacity market auctions covering all four quarters of the 2028 delivery year will be held on 5 November 2026 from 08:00 to 15:59 (UTC+01:00). The pre-auctions determine admission of foreign physical units located in the synchronous profile zone, Lithuania, and Sweden to participate in the subsequent additional auctions, will be run via the Capacity Market Participant Portal (PURM), executed as separate pre-auctions per quarter but in parallel, and require separate financial collateral for each pre-auction.

Why it matters

The pre-auction stage is the gatekeeping mechanism that qualifies foreign capacity to bid into Poland's additional capacity auctions for the 2028 delivery year, directly shaping cross-border participation in the Polish capacity market and the pool of resources available to meet resource adequacy obligations. Its procedural details (parallel quarterly runs, separate collateral per auction) affect operational complexity and market access for foreign market participants from Lithuania and Sweden.

MD analysis

This announcement operationalizes a specific, recurring procedural step within Poland's capacity market design: the pre-auction mechanism that screens and admits non-domestic ('foreign') physical capacity units before they can bid in the main additional auctions. By running four separate pre-auctions (one per 2028 delivery-year quarter) in parallel, PSE is scaling an existing cross-border capacity market access process rather than introducing a new market design principle. The requirement for distinct financial collateral per pre-auction, with explicit instructions on payment reference labeling, indicates an administrative tightening likely driven by prior participant confusion or enforcement needs. For design tracking purposes, this event sits within the broader EU effort to enable cross-border participation in national capacity mechanisms (as foreseen under the Electricity Regulation's cross-border capacity market participation rules), and the Polish-Lithuanian-Swedish configuration reflects existing physical/electrical interconnection and synchronous area linkages. The practical effect is procedural/operational rather than a structural redesign, but it is a concrete, dated implementation milestone with direct consequences for market access timing and collateral management for capacity providers in the three jurisdictions.
