The arrows and figures are measurements, as of 19 October at 08:25. The transmission grid is not shown: we do not have its routes for this country yet.
Interconnections and submarine cables
The flow on each link is the one published by REE, every five minutes. The diagram is not to scale.

There are two cables between Lanzarote and Fuerteventura (the 66 kV one from 2005 and the 132 kV one from 2022); REE publishes a single flow, the total of both, and that is what is shown.
System operator and transmission owner
Red Eléctrica de España (REE) operates the electricity system, balances generation and demand, runs the transmission grid and the submarine cables, and publishes the official real-time data. [1]
Distributors
The local grid, meters, outages and connections are the responsibility of the area's distributor. The CNMC register lists two companies operating in the Canaries. There is no official figure for the territory each one covers. [1] [2]
- e-distribución (Edistribución Redes Digitales, S.L.U. — grupo Endesa) CNMC R1-299
- Distribuidora Eléctrica del Puerto de la Cruz, S.A. CNMC R1-294
Retailers (comercializadores)
Consumers choose their retailer, under the same rules as in mainland Spain. On the regulated market (PVPC) supply comes from the reference retailers; on the free market, from any authorised retailer. No company is the islands' sole supplier. [1]
Reference retailers with national scope (CNMC list, consulted on 2026-09-18) [1]
- Energía XXI Comercializadora de Referencia, S.L.U. (Endesa)
- Curenergía Comercializador de Último Recurso, S.A.U.
- Comercializadora Regulada, Gas & Power, S.A.
- Baser Comercializadora de Referencia, S.A.
- Comercializador de Referencia Energético, S.L.U.

Electricity market price applicable to the Canary Islands
This price is not an individual commercial tariff and may be common to several islands.
Spain · day-ahead market (OMIE)
the cheapest third of the hours the most expensive third
The Canary Islands have no electricity market of their own: REE dispatches the plants, with no bidding. The figures are those of the Spanish day-ahead market (OMIE), in EUR/MWh — a wholesale price, not a bill. The price at which island demand buys its energy is derived from the daily average mainland price, shaped by the hourly profile of Canary demand (Royal Decree 738/2015, Annex I). BOE-A-2015-8646
The regulated PVPC price, paid by household consumers (in EUR/kWh), is published by e·sios for the Canary Islands too. We do not show it yet: access requires a personal token from REE.
- Demand, generation by technology and the flow on the two inter-island links: published by REE for the system and for each of the seven islands, every five minutes.
- Scheduled and forecast demand: for the system and for each island.
- There is no market price specific to the Canary Islands, and REData publishes no prices for the Canary system. The price shown is that of the Spanish market.
- The Canary PVPC, the average demand price and the generation cost of the non-peninsular systems: published by e·sios, but accessible only with a personal token. They are not shown.
- REE data is shown for information purposes, citing the source and the time of the last update, in line with REE's legal notice.
