35 GW of the battery projects in PSE’s queue had until 30 October to pay or lapse. That is 178 of the 279 projects in PSE’s last list before the date.

35 GW had to pay by 30 October 2026, or leave the queue

Two groups faced the date. 141 projects hold connection conditions issued before the act came into force on 30 April 2026 and have signed no agreement: their conditions lapse unless the holder tops up the advance to 60 złoty a kilowatt, up to 6 million złoty, within six months of that date (article 9). 37 projects signed an agreement before the act with a connection date after 30 April 2029: their agreement expires by law unless the holder lodges a quarter of the new security within the same six months (article 11).

Counted from the dates in PSE’s list: the date conditions were issued, the date the agreement was signed and the connection date it sets. The act: Ustawa z dnia 13 marca 2026 r. o zmianie ustawy Prawo energetyczne oraz niektórych innych ustaw, Dz.U. 2026 poz. 516, articles 9, 11 and 38. PSE gives 30 October 2026 as the date in its notice of 15 October 2026. A project that paid stays; one that did not has lapsed. Which paid will show in the editions after the date, which this page reads as they come.

Two more deadlines follow, on building permits

59 agreements, 9.3 GW, were signed between 30 April 2022 and 30 April 2026. They expire unless a final building permit for 80% of the battery’s power and 80% of its energy is notified within 30 months of the act, by 30 October 2028 (article 13). 6 older agreements, 1.5 GW, must show a final building permit within three months (article 14). The act counts those three months from 30 April 2026, but brings article 14 itself into force only six months after publication, so from when they run is disputed, and this page does not choose. 19 of the 59 agreements facing the first of them, 2.6 GW, belong to a company already named in a battery building permit near the site. Every building permit for a battery.

Poland has 65.3 GW of batteries in its grid queues and 11.2 GW with capacity contracts, 2.1 GW being built, and 588 MW running or switched on

One square for every 100 MW. The queue, drawn hollow because it exists only on paper, is standalone batteries with grid offers or signed agreements, from PSE’s national totals. The contracts are the four-hour batteries behind every battery’s capacity obligation for 2027 to 2030. Being built and running are counted battery by battery in the register of every battery. The last row is the reserve product batteries chase most, as PSE buys it each hour.

Sources: PSE’s national totals of 30 September 2026 (distribution part 30 September 2026); the capacity contracts, unit by unit; the batteries running and being built; PSE’s reserve purchases, the average of the last twelve months.

Across all of Poland’s grids, 65.3 GW of standalone batteries hold grid offers or signed agreements, and the lists read here name 86% of it

Every grid operator must publish its own list of the projects asking to connect, and PSE publishes the national totals. PSE’s list covers its transmission grid; Energa’s, Enea’s and Tauron’s cover most of the distribution grids, at 110 kV and below. PGE Dystrybucja’s site refuses automated reading, and Stoen’s list for Warsaw was not found, so their share is shown by difference.

Standalone batteries (type MEE) with connection conditions issued or an agreement signed, at their installed discharge power. PSE’s national totals: Wykaz Zagregowanych Informacji o Przyłączeniach under art. 7 ust. 8n, Table 2. The distribution lists are read row by row from the PDFs each operator publishes; Tauron withholds every applicant’s name, and Enea never states the battery inside its hybrids and often records a battery’s connection only as power drawn from the grid. The national totals and the lists carry different dates, so the comparison is approximate.

The signed agreements peak in 2028 and 2029, and only 1.3 GW is due to connect by the end of 2027

Every connection agreement sets the date the battery is to start taking and giving energy. These are those dates for the 81 agreements that give one, by year, in GW of battery power. A date in an agreement is a plan, not a promise: projects slip, and the Grid Act’s deadlines will end some of them.

PSE’s list (30 September 2026) and Energa’s and Tauron’s lists, the column “data rozpoczęcia dostarczania energii”. 558 signed agreements in the distribution lists give no date, most of Tauron’s and all of Enea’s, so the distribution grids are under-counted here. Every battery project in the four lists as a CSV.

PSE’s own list holds 56 GW of storage in 279 projects

Each project counts at the battery power PSE lists for it, never the whole connection of a hybrid with solar or wind. 12 GW of it is in 81 hybrids.

PSE S.A., the art. 7 ust. 8l list, edition of 30 September 2026, the rows of type MEE (storage) and MIX (a hybrid with storage), at their storage discharge power. A project whose agreed connection date had come by the edition’s date is counted as connected.

Where the queue is

One circle per project, sized by battery power, at the substation PSE names where OpenStreetMap maps one of that name. Blue has a signed agreement, pale blue has conditions only, grey is an application or has left.

283 of 319 projects placed.

Who holds the queue

PSE names every applicant. Most are project companies, one per site; the company register (KRS) says who stands behind each, and who owns the pipeline traces every one to its group.

A megawatt in PSE’s reserves was paid up to about €411,000 over the last twelve months

PSE buys most of its balancing capacity the day before, hour by hour, in seven products, and publishes every price. One megawatt accepted in every hour of its aFRR up procurement would have been paid about €411,000 from November 2025 to October 2026. PSE buys a few hundred megawatts of each product; the queue holds tens of gigawatts of batteries. Every product, month by month.

173 batteries hold capacity contracts for 2027 to 2030, about 11.2 GW of four-hour batteries

URE’s auction results never say which units are batteries, so every published total is an estimate. Counted unit by unit, batteries hold 5,063 MW of de-rated obligation, which stands for about 11,157 MW of four-hour batteries. Every unit, its holder and why it counts as a battery.

315 MW of batteries runs commercially, 273 MW more is switched on, and 2.1 GW is being built

No Polish body lists the batteries running or being built, so this site keeps the list: 59 batteries of 1 MW and more, each with its owner, site, grid, size, suppliers, contracts and dates, and the source for every fact. Of the capacity obligation batteries owe from January 2028, 65% is held by a battery visibly running or being built.

What is not here, and why

A meter on any battery, because PSE publishes output only for its largest units and no battery is among them, and ENTSO-E shows none. Any instruction PSE gives a battery, because PSE publishes balancing only in totals. PGE Dystrybucja’s and Stoen’s connection lists, not yet read: PGE’s site sets a picture test for every visitor, and Stoen’s bars automated reading.
