Everything below comes from what CATL publishes about the TENER Sodium: 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 |
|---|---|---|---|
| Modular block, 'more than 30 MWh' rated capacity; 1/2/4/6/8 h configurations | 30 MWh | not published | not published |

Key facts
- First CATL sodium-ion utility BESS; >30 MWh modular block, each module ≈42 t, 34 units per 1 GWh site
- Energy and power blocks decoupled: 1, 2, 4, 6 and 8-hour durations
- Dedicated bidirectional DC voltage-regulation stage for the wide sodium-ion voltage range (claimed ~2% RTE gain); auxiliary consumption 1%
- Same footprint/enclosure as CATL LFP systems; 65 dB noise; upgrade path to 2000 V architecture reserved
- Deliveries in China from September 2026 (1 GWh planned by end-2026), international from June 2027
What CATL does not publish for this model
These fields are empty because no public datasheet or release states them. That is information too: ask for these numbers before you shortlist.
