Polish Traders Press PSE for Clarity on November Cross-Border Power Rule Overhaul
With EU changes to cross-border power trade regulations due in November, Polish market participants say their transmission system operator has left them without workable guidance.
Polish energy traders went public on Thursday (2026-07-24) with a blunt message to transmission system operator PSE: the market does not know what the November EU rule change to cross-border power trading will mean in practice, and needs answers before positions can be sized with any confidence. "What we know now is that we know nothing for sure really," the head trader at a Polish firm told Montel News.4
That kind of uncertainty, voiced by active market participants rather than lobbyists or trade bodies, carries weight. Cross-border capacity allocation and flow scheduling are the plumbing of European power trading. If counterparties on both sides of a border are operating under different assumptions about how the new framework will function, the spread between bids and offers widens, liquidity thins, and hedging costs rise.4
PSE sits at the center of this. As Poland's transmission system operator, it is responsible for implementing the EU changes domestically and for coordinating with neighbouring TSOs on the practicalities of daily and intraday auctions. Traders are not asking PSE to rewrite regulation — they are asking it to explain how existing operations will look different after November, and what the transition timeline entails.4
The EU energy regulator ACER has been pushing on grid coordination from a different angle. In a May report, ACER urged southeast European TSOs to accelerate grid upgrades, tighten cross-border coordination, and apply EU market rules more consistently, citing the region's 2024 power price spikes as evidence of what poor interconnection management produces. Poland is not in southeast Europe, but the regulatory direction is the same: Brussels wants TSOs to be more transparent, faster-moving, and better aligned with market participants ahead of rule changes, not after them.1
The November deadline now sits uncomfortably close. Traders typically need several months of lead time to adjust internal systems, renegotiate bilateral agreements, and revise hedging strategies around structural changes in how cross-border capacity is allocated. A rule change that arrives with ambiguity intact forces participants to either sit on the sidelines or take on basis risk they cannot properly quantify. Neither outcome is good for liquidity.4
Poland's power market is not an island. The country is a net importer at certain times and an active transit corridor, meaning that any friction introduced by a poorly communicated rule transition will be felt by counterparties in the Czech Republic and beyond — not just domestic generators and retailers. ICE Endex TTF front-month was flat at €61.90/MWh on Thursday morning (2026-07-24), offering no particular directional signal for European gas. But if cross-border capacity allocation becomes less predictable in November, the risk of price divergence between Polish and neighbouring zones increases.4
Poland has been navigating several overlapping regulatory pressures simultaneously. The European Commission filed suit against Poland earlier this year for failing to fully transpose EU Emissions Trading System revisions into national law, a separate but related sign that Warsaw's implementation of Brussels directives has lagged behind the regulatory timetable. That legal action, filed on Thursday (2026-06-04), adds to the friction that traders are already managing when they try to price Polish market exposure.2
On gas, Poland received clearer news more recently. The national regulator on Wednesday (2026-06-03) approved Gaz System's new tariffs, including a 58% cut from EUR 3.52/MWh for a key import pipeline, which traders described as a significant shift for flows from Germany and for transit volumes to neighbouring markets. That tariff clarity, if anything, makes the absence of equivalent transparency on the power side more conspicuous.3
For now, the traders' public call to PSE is an early signal, not yet a market dislocation. But November is four months away. If PSE does not publish detailed operational guidance in the coming weeks, the period before implementation will be marked by reduced participation in forward capacity auctions, wider bid-ask spreads in the Polish power market, and hedging strategies built on assumptions that may prove wrong. The specific trigger is whether PSE issues formal market guidance — and how quickly ACER responds if it does not.4,1
