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.

Column	Description
`dem`	Total electricity demand
`eol`	Wind (Eólica)
`nuc`	Nuclear
`gf`	Natural gas (Gas natural)
`car`	Coal (Carbón)
`cc`	Combined cycle (Ciclo combinado)
`hid`	Hydropower (Hidráulica) — can be negative (net pumping)
`sol`	Solar (legacy total; may overlap with `solFot` + `solTer`)
`solFot`	Solar photovoltaic
`solTer`	Solar thermal
`termRenov`	Renewable thermal (biomass)
`cogenResto`	Cogeneration & other
`aut`	Self-generation (Autogeneración)
`conb`	Pumped storage consumption
`turb`	Pumped storage generation
`gnhd`	Non-distributable hydro minus pumping
`bat`	Battery discharge
`consBat`	Battery charging
`vap`	Steam (Vapor)
`inter`	Net international exchange (positive = export)
`icb`	Islanded consumption blocks
`expAnd` / `expMar` / `expPor` / `expFra` / `expTot`	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

hid negative values indicate net pumping (pumps consume more than turbines generate).
sol vs solFot/solTer: sol is a legacy aggregate. Prefer solFot + solTer for accurate solar.
