The arrows and figures are measurements, as of 21 October at 23:00. 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.

Project	Flow now	End points	Voltage	Capacity	Length	Cables	In service since	Sources
SACOI (Sardaigne–Corse–Italie)	44 MW→ Corsica	Lucciana↔ Sardegna · Toscana	200 kVdirect current (HVDC)	50 MW (soutirage Corse)	—	—	1967 · Lucciana 1986	[1] [2]
SACOI 3 (renouvellement)	under construction	Lucciana · Bonifacio↔ Sardegna · Toscana	200 kVdirect current (HVDC)	100 MW (150 MW si SARCO indisponible)	—	—	2029	[1] [2]
SARCO (Sardaigne–Corse)	same flow as above	Bonifacio↔ Santa Teresa di Gallura	—alternating current	100 MW	—	—	2008	[1]

The operator publishes one combined flow for these links; it is shown on the first line and applies to both.

Electricity market price

There is no market price for Corsica: the island is supplied under a regulated tariff, without a wholesale market of its own. No price from another zone is shown here.

What data exists and what does not

Real-time data: demand and generation by technology, as published by EDF · Open Data Corse; the page shows the latest reading with its time.
EDF · Open Data Corse does not publish consumption separately: the demand shown is the total of all injections (generation, links and storage balance), which by definition equals what is consumed.
CO₂ emissions: estimated from the generation mix with lifecycle factors; nobody publishes measured emissions for Corsica.
Market price: none. Corsica is supplied under a regulated tariff.
Flows on the interconnections: published in real time.

Frequently asked questions

Where do the figures on this page come from?

From EDF · Open Data Corse. Every value keeps the time of its reading and the link to the source; nothing is estimated except the CO₂ figure, which says so.

Is Corsica connected to another electricity system?

Yes, through: SACOI + SARCO (Sardegna · Toscana). The table above gives the voltage, capacity, length and year of each link, with its source.

Is there an electricity market price for Corsica?

There is no market price for Corsica: the island is supplied under a regulated tariff, without a wholesale market of its own. No price from another zone is shown here.
