VoltGrid BESS1 MWh — 1000+ MWh

Scale 50–200 MWh

100 MWh Energy Storage — Utility-Grade Installation

Short answer

We build a 100 MWh storage system from 16–20 × 20ft containers at 5–6.9 MWh each, with a power of 25–50 MW and an HV 110 kV connection. The site footprint is 1.5–2.5 ha, and we deliver equipment in 3–4 transport batches.

  • 16–20 × 20ft containers
  • 25–50 MW
  • 0.25C (4h) most commonly, 0.5C for a capacity profile

Who this scale is for

  • A developer with a building permit and an HV connection agreement
  • A fund requiring a bankable package of guarantees and an LTSA
  • An operator of a PV/wind portfolio above 100 MW
