315 MWRunning · 13 batteries
273 MWSwitched on · 14 batteries
2,149 MWBeing built · 12 batteries
971 MWFinanced, not started · 20 batteries
59 batteries of 1 MW and more, each with its status on 20 October 2026 and the dated source for it. 2,034 MWh is running or switched on; 8,199 MWh is being built.
No Polish body lists the batteries that are running, and none lists those being built. This register does, one battery at a time: who owns it, where it is, which grid it joins and where, its power and energy, who supplied and built it, its capacity contract, grant, trader and lenders, and every date from the connection agreement to commercial operation. It starts from the storage registers Tauron and Enea keep under the Energy Law and the four connection lists, joins URE’s capacity results unit by unit, and adds what owners, lenders, suppliers and the trade press have published. Every fact carries its link. The whole register as a CSV.
Of the capacity batteries owe from January 2028, 65% is running or being built and 29% has only a building permit behind it; from 2029, 16% is running or being built
A capacity contract is a promise to be available from 1 January of its first delivery year, with penalties for a unit that is not. Each bar is the obligation batteries won for that year, split by the furthest step the battery behind it has visibly reached: running, being built, financed, or a building permit issued to the contract holder and nothing since. For 2029, 7% is financed and not started, 25% has a permit only, and for 51% nothing has been found at all. A four-hour battery takes a year or more to build, and January 2028 is fourteen months away.

MW of de-rated capacity obligation, URE’s final results; batteries counted unit by unit as on the capacity page. A unit counts as running, built or financed when the register matches it by its unit code; as permit only when its contract holder is named as investor in a battery building permit in GUNB’s register, matched by company name. A unit can be under way without a public report, so the hatched share is the most it could be, not the least.

The two owing from 1 January 2027, Battery ESS-1 and PKE Pomorze, are the ones to check first: their delivery year starts in ten weeks, and no permit in either name has been found.
If every owner’s date holds, Poland will have about 2.0 GW of batteries by the end of 2027 and 3.5 GW by the end of 2028
Each battery by the year its owner or the press says it will start commercial operation, split by its status today. A date said by an owner is a plan; several here have slipped already, and the ones only financed are the least certain. A date given as the turn of two years is counted in the later one.

What is known, and what is still missing
For each fact, how many of the batteries in each status have it. The darker the cell, the more complete. Owners, sizes and statuses are near complete; exact sites, building dates, switch-on dates and balancing qualification are the gaps, and most need a person to ask.

Points to check first
- Two batteries owe capacity from 1 January 2027 with no sign of building, and no building permit in either name. Battery ESS-1 sp. z o.o. holds 9.2 MW of obligation (JRM/777) and its owner is not known; PKE Pomorze holds 6.65 MW (JRM/774) for a 7.5 MW Hynfra project near Wrocław.
- Renegia Bulla won capacity for 2026, and none of its batteries is in Tauron’s register. It holds 11 units around Opole, about 50 MW of obligation from 2028, and quarter-long contracts for 50.2 MW in the first and fourth quarters of 2026, which require delivery this year. GUNB’s register shows building permits in its name in Opole, decided on 31 March 2025, and nothing since.
- PSE’s list of 31 August still shows Turośń Kościelna as an agreement, not as connected, though the plant opened on 30 July and the same row gives 30 July as its delivery start.
- For three large batteries, PSE’s agreed connection date is years after the planned opening. Gdańsk II is due around the turn of 2027 and 2028 and its PSE date is June 2032; Dzięgielewo’s is March 2030; Ełk runs on a temporary 220 kV connection, and its PSE row is for a later 400 kV connection, dated February 2030.
- Stary Grodków’s capacity contract is held by Respect Energy, not EDF. URE lists Respect Energy S.A. for JRM/885, which fits the news that Respect Energy now trades the plant. A search by EDF’s name misses it.
- Tauron’s Proszówek battery does not fit the contract of the company that owns it. The register lists 9.5 MW under FF Park PV sp. z o.o.; the same tax number holds JRM/2150, whose obligation stands for a 55 MW four-hour battery, probably the planned 47 MW Proszówek II.
- The grid operators’ registers carry errors, kept as published and flagged in each row: a 3.084 MW battery at Bytnica listed with 0.006 MWh, company founding dates given as storage start dates, a nine-digit KRS number, and a start date after the entry date.
Where the sources disagree
Where two sources give different figures, both are kept, in the row and here. The register uses the owner’s own figure unless a grid operator’s register is more recent.
Every disagreement, battery by battery
| Battery | What differs |
|---|---|
| Turośń Kościelna BESS | PSE queue row is for 294 MW against 200 MW built. The PSE list of 31 Aug 2026 still shows the agreement in force, not "connected", although its delivery start date (30 Jul 2026) has passed. IFC had planned construction completion for June 2026. |
| Stary Grodków BESS | Size: 50 MW / 120 MWh (EDF, gramwzielone, register 120.36 MWh) vs 50 MW / 100 MWh and two-hour duration (gramwzielone 20 Oct 2026). Register installed power 60.192 MW with 50 MW discharge; ESS News says 60 MW installed, 50 MW grid connection. The URE list names Respect Energy, not an EDF company, as capacity supplier. |
| Nowe Czarnowo I BESS | 24 MW / 56 MWh (Energix, Axpo, gramwzielone) vs 28 MW (Modo, Apr 2026). |
| Łozienica BESS | 9.4 MW / 18.8 MWh (NGEN, press) vs 9.636 MW / 19.272 MWh (Enea register). Modo counts 9.4 MW. |
| Bystra hybrid BESS | Gramwzielone (Dec 2022) said it would be connected to the national system after the pilot phase, so its grid status in 2021-2022 is unclear. |
| Garbce traction BESS | Energy: 1.2 MWh usable (Railway Gazette) vs 1.88 MWh total / 1.5 MWh usable (gramwzielone 15 Jun 2021). Power 5.5 MW (Railway Gazette) vs 5 MW (Railtech). |
| Herby BESS | Register: 5.04 MW / 10.03 MWh vs 5 MW / 10 MWh. Register start date (28 Jul) is after first-entry date (10 Jul). |
| Tauron BESS Przewóz | Register: 4.41 MW installed / 4.0 MW discharge / 17.556 MWh, vs 4 MW / 16 MWh in Tauron statements. Register owner is TAURON Ekoenergia, capacity contract holder TAURON BME4. Register lists the site as Rybitwy; Tauron calls it Przewóz (adjacent Kraków districts); matched by Tauron press saying both Kraków units sit on hydro-plant land. Building permit for "BESS Przewóz" (GUNB ST-MA-KR/WNIOSEK/14947/2025) names TAURON BME4 sp. z o.o. as investor; the register lists the battery under TAURON Ekoenergia. |
| Tauron BESS Dąbie | Register: 4.41 MW installed / 4.0 MW discharge / 17.556 MWh vs 4 MW / 16 MWh (Tauron). |

| Zwartowo III PV + BESS | PSE agreement date 2010-05-05 reflects the original wind-farm agreement. |
| Tauron hybrid Stare Bogaczowice I | Tauron also holds capacity unit JRM/1399 "ME Stare Bogaczowice 3" (TAURON BME7, 63.121 MW = 103 MW four-hour equivalent), which fits Stare Bogaczowice II (105 MW, no grant), not this project. |
| Trześń BESS | Source is sponsored content. Link between Eko Prime's Trześń contract and PEI PV 03's grant is by place name only. |
| CLIP logistics centre BESS near Poznań | Four systems of about 2 MW each; only the total is above 1 MW per site if each is 2 MW (not stated). |

Left out, and why
A project enters the register only with a dated source for building, a signed supply or building contract, or closed financing. Those with only grid conditions, a grid agreement, a capacity contract or a recommended grant are left out; the most notable are here, to be moved in when that evidence appears.

How it was built
Every battery of 1 MW and more in Tauron’s and Enea’s storage registers; the rows marked connected in the four connection lists; then a search for every owner and every capacity contract holder, the storage sections of gramwzielone.pl from May to October 2026 and energy-storage.news back to March 2025, lenders’ disclosures (EBRD, IFC), suppliers’ releases and stock-exchange filings. A status is given only with a dated source: running when a source reports commercial operation or the unit has run for years; switched on when it is connected and powered with no commercial operation reported, which an entry in a storage register shows, since those registers hold connected batteries only; being built when a dated source says building has started; financed when a supply or building contract is signed or financing has closed, and for Tauron alone, a secured grant with Tauron’s statement that the project is in progress. Each battery is matched to its connection row and its capacity unit by tax number, company name, or for Tauron, whose list withholds names, by substation code and size, marked inferred. Money in euros at the ECB rate of 20 October 2026, 4.3768 zł, with złoty in brackets.

PGE Dystrybucja’s area is the weakest: its site could not be read from a data centre.
