+# 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.
