Energy in Portugal (2026)
Updated August 2026. Portugal's energy market is liberalised. You can choose your electricity and natural-gas supplier on the mainland, but the distribution grid is a regional monopoly. ERSE regulates prices and the official simulator helps compare tariffs. Bills split into energy, grid access, and taxes. All household contracts require a NIF, supply address, and IBAN.

How does the energy market work in Portugal?
The electricity and natural-gas market is liberalised on the Portuguese mainland. You can choose your supplier freely, but distribution belongs to regional grid operators: E-Redes on the mainland, EDA in the Azores, and EEM in Madeira. Switching supplier does not interrupt supply.
ERSE sets the regulated electricity tariffs (SU Eletricidade) annually and monitors the free market. The ERSE simulator compares tariffs using your delivery point code (CPE) and consumption.
How much do electricity and gas cost in Portugal?
For a typical profile of 1,900 kWh/year at 3.45 kVA, annual electricity bills range from EUR 397 to EUR 485 on the free market. Bills split into energy and supply (about 45-55%), grid access tariffs (30-35%), and taxes and levies (15-20%).
Natural gas depends on network availability at the address. For 2,000 kWh/year, fixed tariffs in August 2026 range from EUR 270 to EUR 311 per year.
How do you set up electricity and gas in your own name?
You need a NIF, supply address, and the CPE for electricity or CUI for gas from the meter. Contracts can be signed online, by phone, or in store. Most discounts require direct debit from a Portuguese IBAN and electronic billing.
When moving house, request a change of titleholder or a new contract. If the meter is disconnected, ask the grid operator for reconnection, which may require a technician visit.
