| `ts` | timestamp (UTC) | Year |
| `variable` | str | Renewable share / Carbon intensity / Elec price / Gas price / Import dependency / GHG |

## Coverage note

The file runs to **2026-01-01**, but 2 of 6 `variable` values stop earlier. This reflects the upstream publication schedule, not a gap in processing - the remaining values are current.

| variable | last value | behind by |
|---|---|---|
| `Energy import dependency (%)` | 2024-01-01 | 731 days |
| `Total GHG emissions (Mt CO2e)` | 2024-01-01 | 731 days |
