Utilities in Monaco: Electricity, Gas & Water

How Utilities Work in Monaco

Monaco has dedicated state-concession companies for each utility. There is no choice of provider — each utility has a single supplier for the entire Principality.

Electricity and Gas — SMEG

SMEG (Société Monégasque de l'Electricité et du Gaz) has been the sole electricity and gas distributor in Monaco for over 130 years. SMEG handles supply, distribution, metering, and billing for both electricity and natural gas throughout the Principality. It also operates Monaco's public lighting network.

Monaco uses standard European voltage (230V, 50Hz) with Type C and Type E plugs (two-pin). Visitors from the UK, US, or other non-European countries will need an adapter.

Approximately 75% of electricity consumed in Monaco comes from renewable sources, reflecting the Principality's commitment to its energy transition.

Setting up an account: When moving into a new property in Monaco, your landlord or property manager typically coordinates the SMEG account transfer. For new connections, contact SMEG directly or visit their offices.

Water — SMEaux

SMEaux (Société Monégasque des Eaux) is the concessionaire of Monaco's public water distribution service. SMEaux manages drinking water supply from source to tap, including local water treatment at the Larvotto facility, storage, transport, and customer billing.

Monaco's tap water is safe to drink and meets strict quality standards. The price is set twice a year and covers both supply and wastewater treatment — see where Monaco's water comes from and what it costs for the current tariff and the full picture.

Customer service: 29 Avenue Princesse Grace (opposite the Larvotto beaches). Open Monday–Friday 8:15–16:45 without interruption. Free parking available.

Wastewater — also SMEaux

Wastewater is not a separate provider. SMEaux also operates the UTER, Monaco's wastewater treatment plant, built into the basements of the "Le Triton" building in Fontvieille. It treats sewage from Monaco and from neighbouring Beausoleil, Cap-d'Ail and La Turbie before discharge into the Mediterranean, 800 metres offshore.

Waste and recycling — SMA

SMA (Société Monégasque d'Assainissement) is a different company, and handles household waste, street cleaning and Monaco's waste-to-energy plant — not water. See waste and recycling.

Practical Information

• Utility bills in Monaco are typically included in certain rental arrangements — check your lease to see what is covered
• For new residents, setting up utilities is usually handled through your landlord or the building's property management (syndic)
• Monaco does not have separate electricity or gas providers to choose between — SMEG is the only option
• Power outages are rare in Monaco due to the underground cable network
