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