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
Though tolls are the same for the entire country and it does not matter if you are on the open or regulated market, not everyone pays the same.
You cannot choose your access tariff; rather, it is set by other aspects of your contract. Your toll depends on your power contracted (in the case of electricity) or your annual consumption (in the case of gas).
- Electricity: most homes have less than 10 kW of power, and so their access tariff will be 2.0. There are three types: simple (2.0 A), which has an hourly breakdown in two periods (2.0 DHA) and that which has an hourly breakdown in three periods and is used especially for electric cars (2.0 DHS). If someone needs more than 10 kW of power, they will follow this same scheme but with the 2.1 access tariff, which logically, will be more expensive. Those with power greater than 15 kW will have 3.0.
- Gas: here, the power contracted is not important, rather, the annual consumption and pressure of the supply is what counts. We will only focus on the pressures equal to or less than 4 bars, which the vast majority of domestic consumers have. For these pressures, the access tariff will be 3.1 in annual consumptions lower than 5,000 kWh and 3.2 in consumptions between 5,000 and 50,000 kWh per year. There are many more rates (3.3, 3.4) but almost all Spanish homes have between 3.1 and 3.2.
To give you an idea: a home that uses gas for hot water and heating has an annual consumption of 9,000 kWh. However, if heating is separate from natural gas, consumption drops to 3,000 or 4,000 kWh per year.
