4,337 MW of batteries are registered as operating in Germany. 9,326 MW more are registered as planned. A further 3,304 MW registered as planned is held apart as doubtful. The queue behind them is not public.

Where the batteries are

One circle per battery of a megawatt or more, at the coordinates its operator registered, sized by power. Yellow operates; blue is registered as planned and counted; pale blue is registered as planned and held apart.

1367 of 1372 units carry coordinates in the register. Pumped storage is left off this map and drawn in grey on the Atlas.

What the register can say, and what it cannot

A unit registered as planned is one its operator chose to register before it was built. The connection queue is a separate list, and Germany publishes it only as totals: the Bundesnetzagentur counted 18,158 connection requests for batteries in 2025, about 574 GW, and 1,937 connection promises, about 54 GW, some of them answering older requests. Those figures are the regulator’s own, published on SMARD in August 2026, and they sit beside the register here, never inside it. The transmission operators moved in 2026 from first come, first served to allocation by how far along a project is.

What is held apart from the planned figure, and why

707 batteries with 12,630 MW are registered as planned. We count 9,326 MW of them in the planned figure and hold the other 3,304 MW apart, because each of those entries looks doubtful for one of the four reasons below. Nothing is deleted: every unit stays on the Atlas and in its download, marked with the reason.

3,000 MW in 3 entries are registered, but we found no announcement of them by the owner. They are held apart until the owner confirms them.

7.5 MW in one entry looks like a duplicate: the same plant appears twice, under two operators.

197 MW in 14 entries are one series that a single operator registered together. Each sits at its own site, but every one passed its planned date without being updated, so the series is held apart until its operator updates it.

100 MW in 34 entries have a planned date that passed more than a year before this export, the oldest in October 2019. Their operators have neither marked them as built nor withdrawn them.

The entries above were decided by hand, on 11 October 2026 and, for the series, on 16 October 2026. The Atlas lists each of them with its evidence, and the 34 overdue entries as well.

Pumped storage

6,267 MW of pumped storage in 73 units operates in Germany. The register also lists 30 units with 3,633 MW in Austria and Luxembourg, because they are wired into the German grid, and gives them no German state. We count them apart from the plants in Germany. Neither group is ever added to the batteries.

A check against the regulator’s own figure

The Bundesnetzagentur counted about 3.6 GW and 6 GWh of batteries in operation at medium voltage and above, as pv magazine reported on 25 August 2026. The batteries on this page commissioned by 30 June 2026 come to 3,660 MW and 6.3 GWh, which agrees. The regulator draws its figures from this same register, so the agreement shows that we read the register as the regulator does; it cannot show that the register is right. The regulator’s count of 1,292 units takes in units of any size, many of them under a megawatt, so it cannot be set beside our count of units.

Corrections shown on these pages

Some entries carry an obvious slip, and these pages show them corrected. Four batteries have their storage entered in MWh where the register asks for kWh, so a 5 MW battery appears to hold 9.556 kWh, about 7 seconds of its power. We read the figure as MWh. They are Batteriespeicher Saarlouis-Lisdorf, Strs, Stromspeicher 1 and ABR955057773547. The register and the owner disagree on the power of two batteries: Big Battery Lausitz (66 MW in the register) and Batteriespeicher Cremzow (2.8 MW in the register). We count the register’s figure, which is the power the operator declared for the grid. One unit is registered as commissioned in 1923, which cannot be right, and the date is left blank. The register’s own values stay in the Atlas download, beside ours.

Checks

25 entries look odd when read mechanically: a net power above the gross, a capacity under a quarter of an hour or over twelve hours of the power, no state given, or two planned units of one operator in one municipality with the same power. They stay in every count and are listed on the Atlas with the reason. The check is where the work on this register starts.

The queue figures are the Bundesnetzagentur’s evaluation of its 2025 monitoring data, published on SMARD in August 2026. The flags decided by hand were checked on 11 October 2026 against the register and the owners’ own announcements. Nothing on this page is modelled.
