If you want to be connected to the electrical or piped natural gas grid, you have to pay tolls. It doesn't matter which company you are with or where you live. If you are on the open market, the cost of tolls will be included in the price of kW of power and kWh of consumption. If you are on the regulated market (PVPC rate), it will be broken down. Regardless, the tolls will be the same.
The cost of the tolls or access tariffs is decided by the competent Ministry responsible for Energy. Its impact is distributed throughout the entire bill (both fixed term and variable term) to protect the viability of the system, even in times of low energy consumption.
Types of tolls or access tariffs
Even though tolls are regulated costs and it does not matter if you're in the free market or PVPC, not everyone pays the same.
You cannot choose your access tariff, but it is allocated in accordance with other aspects of your contract, such as your contracted power and your consumption.
- Electricity: most households have a power of less than 15kW, so their access tariff is 2.0TD. Those who need more power, like some businesses and many companies, will have 3.0TD or 6.XTD access tariffs. If you want to know more about tolls, you can consult Endesa's information on new electricity tariffs.
- Gas: here what is taken into account is not the contracted power but the annual consumption and the pressure of the supply. We will focus only on pressures equal to or less than 4 bars, which are those that the vast majority of domestic consumers have.
For these pressures, the most common annual consumption for Spanish households is less than 5,000 kWh per year or consumption between 5,000 and 50,000 kWh per year. These values correspond to access tariffs 3.1 and 3.2, which with the new regulations on gas access tariffs have been re-named as RL.1 and RL.2 respectively.
There are many more access tariffs, but almost all Spanish households have one of these two. To give you an idea: A home that uses gas for hot water and heating has an annual consumption of about 9,000 kWh. However, if the heating does not use natural gas, consumption goes down to 3,000 or 4,000 kWh per year.
