Containerised energy storage technology — parameters and figures

Short answer

The 2026 standard: a 20 ft container rated 5.0–6.9 MWh, liquid cooling that holds cell-to-cell temperature spread below 3 K, LFP cells of 314–1,130 Ah and PCS units of 1.25–2.5 MW with efficiency up to 98.8%.

  • Unit capacity of 5.0–6.9 MWh
  • AC round-trip efficiency of 86–89% at 0.5C
  • Cooling system parasitic load of 1.5–2.5%
