| # UK Electricity Generation Mix & Carbon Intensity, 2019–2026 (TsFile) |
|
|
| Apache TsFile version of [`Rif-SQL/uk-electricity-generation-mix-2019-2026`](https://huggingface.co/datasets/Rif-SQL/uk-electricity-generation-mix-2019-2026). |
|
|
| ## Overview |
|
|
| Half-hourly electricity generation by fuel type and carbon intensity for Great |
| Britain, sourced from the NESO (National Energy System Operator) Historic GB |
| Generation Mix. Each record is a 30-minute settlement period giving generation (MW) |
| per fuel, aggregated totals, each fuel's share of the mix (percent), and the grid |
| carbon intensity. |
|
|
| - **Time range:** 2019-01-01 00:00 → 2026-03-19 21:30 (UTC). |
| - **Granularity:** 30-minute intervals. |
| - **Records:** 126,476. |
| - **Coverage:** one continuous national (GB) series — no per-region/per-unit split. |
|
|
| ## Schema (TsFile structure) |
|
|
| - **Time** (INT64, milliseconds) — the settlement-period timestamp (source `DATETIME` |
| in UTC). |
| - No TAG columns — this is a single national series. |
| - **FIELD columns** (33) — all kept as-is: |
| - Generation by fuel (MW): `GAS`, `COAL`, `NUCLEAR`, `WIND`, `WIND_EMB`, `HYDRO`, |
| `SOLAR`, `BIOMASS`, `STORAGE`, `IMPORTS`, `OTHER`. |
| - Aggregated totals (MW): `GENERATION`, `FOSSIL`, `LOW_CARBON`, `ZERO_CARBON`, |
| `RENEWABLE`. |
| - Per-fuel / per-group share (percent): the corresponding `*_perc` columns. |
| - `CARBON_INTENSITY` — grid carbon intensity (gCO₂/kWh). |
| |
| Column names are lower-cased in the TsFile table. |
|
|
| ## Usage |
|
|
| Read the `.tsfile` files with the Apache TsFile Java or Python SDK. |

| ## Conversion notes |
| |
| - Time comes from the source `DATETIME` column (UTC), parsed to epoch milliseconds; |
| the `DATETIME` column is folded into Time and not retained as a duplicate field |
| (fixed 30-minute cadence, unique timestamps → lossless). |
| - No TAG columns and no rows dropped; all 33 numeric measurement columns are kept as |
| FIELD. |
