REE Iberian Peninsula Electricity Generation
Electricity demand and generation by source for the Iberian Peninsula, sourced from REE (Red Eléctrica de España). Covers 2008–present at 5-minute resolution, fully deduplicated.
Dataset Summary
- 1,931,443 rows × 38 columns
- Date range: 2007-12-31 → 2026-05-14
- Resolution: 5 minutes
Columns
33 columns from the REE API, plus ts (timestamp). All values in MW.

Exports by destination / total |
impFra / impPor / impMar / impAnd / impTot |
Imports by origin / total |
dif |
Balancing difference |
Column History
The API schema has always contained all 33 columns, but several transitioned from zero to active (or vice versa) as infrastructure was built or reporting changed:
| Column(s) | Change | Date |
|---|---|---|
icb |
zero → active | 2013-02-28 08:50 |
sol |
zero → active (solar aggregate) | 2013-07-24 09:10 |
solFot, solTer |
zero → active (solar split into PV + thermal; sol kept as legacy aggregate) |
2015-04-30 22:00 |
termRenov, cogenResto |
zero → active | 2015-04-30 22:00 |
gnhd, conb |
zero → active (pumped storage detail) | 2022-01-25 |
turb |
zero → active (pumped storage turbine) | 2024-09-19 08:45 |
exp*, imp* |
zero → active (per-country exchange breakdown) | 2024-09-18 02:00 |
bat, consBat, dif |
zero → active (grid-scale batteries) | 2024-10-24 |
vap |
zero → active (steam generation) | 2025-07-14 14:00 |
gf |
active → zero (natural gas fuel discontinued) | 2024-10-01 13:00 |
aut |
active → zero (self-generation reporting discontinued) | 2025-12-11 11:10 |
Usage
from datasets import load_dataset
ds = load_dataset("daniel-dona/ree-data")
Notes
hidnegative values indicate net pumping (pumps consume more than turbines generate).solvssolFot/solTer:solis a legacy aggregate. PrefersolFot+solTerfor accurate solar.- Static snapshot as of 2026-05-14.
