If you sell EPC & grid connection
25 units

planned at ≥ 100 MW: 65% of all planned MW.

Only 3 run at that size today. Largest planned: 1,000 MW; largest running: 140 MW.

If you sell O&M & asset management
4.4 GW

registered to start by Q3 2027 (322 units).

2.1 GW actually went live in the last 12 months. 2026: 1.8 GW so far vs 0.8 GW in all of 2025.

If you sell EMS, trading & insurance
44%

of planned MW is long-duration (≥ 3.5 h).

vs 1% of what runs today. Average 3.0 h planned vs 1.8 h operating.

If you sell anything that needs a site visit
43%

of planned MW sits in Sachsen and Brandenburg.

Bayern has the most planned units (236), but they are small.

Map & data sources

Datenquelle: Marktstammdatenregister (Bundesnetzagentur) · Datenlizenz Deutschland – Namensnennung – Version 2.0 · Daten bearbeitet

Sites: registered battery units ≥ 1 MW (status In Betrieb / In Planung), export of 17 Oct 2026. Units at the same point are merged per registered start quarter; positions are rounded to ~100 m, and to ~1 km unless the operator is a capital company or public body (so e.K., GbR, KG, oHG and unclear legal forms are approximate). “Start” is the registered commissioning quarter, not a forecast. Group counts are resolved from public register data and are approximate.
