Supplier companies and their tariffs

You must sign your Gas Natural contract with a supplier company. You can opt for one of its deregulated tariffs, in competition with those of the other suppliers, or for last-resort tariffs (LRT).

1- The last-resort tariff is the regulated price at which suppliers of last resort sell natural gas to end consumers. Last-resort tariffs are set by the Administration.


Last-resort tariffs can be used by consumers that have gas-pipeline connections with a pressure under or equal to 4 bars and an annual consumption under 50,000 KWh.


There are two last-resort tariffs, depending on the customer's annual consumption:

a) T.1 for a consumption equal to or under 5,000 kWh/year. This is the usual consumption range in a household with a natural-gas cooker and/or boiler.

b) T.2 for a consumption over 5,000 KWh/year and equal to or below 50,000 kWh/year. This is the usual consumption range in a household with natural-gas central heating. 


The marketing companies that undertake to provide last-resort supplies are as follows:


- EDP Comercializadora de Último Recurso, S.A.

- Endesa Energía XXI, S.L.U.

- Gas Natural S.U.R. SDG, S.A.

- Iberdrola Comercialización de Último Recurso, S.A.U.

2- Deregulated tariffs. If you wish, you can also hire your supply at a price and under conditions that are freely neogotiated with a supplier. You can consult several aspects of the natural-gas market on the CNMC webpage, in the Energy/Consumers/Natural Gas area; or by calling 914329600.
