Everything below comes from what CATL publishes about the TENER: the datasheet, the product page and press releases. Where a figure is not published, the field says so — we do not estimate.
Variants
Energy figures are nominal (beginning of life) as published by the manufacturer. One model, several duration options — the same enclosure with different power ratings.
| Variants | Energy | Power | Duration |
|---|---|---|---|
| 6.25 MWh 0.5P (2 × 1562.82 kW); brochure states 2 h/4 h system compatibility | 6.25 MWh | 3.126 MW | 2 h |

Price signal
$75–100/kWh
Our estimate from benchmarks, not a CATL offer: 4-hour LFP systems averaged RMB 541.3/kWh (~$75) in Chinese H1 2026 tenders (CNESA), FOB-China 5MWh DC blocks for Europe ran $71–89/kWh (SMM, June 2026); the market prices a premium over average for TENER's five-year zero-degradation claim. Ex-works China DC block; US/EU turnkey installs run multiples higher ($150–320/kWh installed).
