VoltGrid BESS1 MWh — 1000+ MWh

Scale axis

Battery energy storage by project scale — from 1 MWh to 1000 MWh

Short answer

The offering covers five scale bands: 1–3 MWh, 3–10 MWh, 10–50 MWh, 50–200 MWh and 200–1000+ MWh. Every band is built from the same 1 MW / 2 MWh block in a 20 ft container; only the number of units and the connection voltage level change.

  • The same architecture at every scale band
  • Voltage level from 400 V LV up to 220 kV HV
  • CAPEX and lead time stated explicitly for each scale
