Main changes
One of the main changes introduced by the new regulations is that customers with a power rating equal to or lower than 15 kW will pay the same toll tariff, which is now called 2.0TD. There are also new time periods for energy and power.
New 2.0TD tariff hourly distribution
The 2.0TD tariff periods are defined according to the day of the week, the time of day and by geographical areas of residence which make up the power schedule (Peak and Off-peak) and energy billing periods (Peak, Intermediate and Off-peak). The Peak power period consists of Peak and Intermediate energy periods, while the Off-peak rate is the cheapest period and coincides with both terms. For the Peninsula* the schedule is:

Additionally, weekends (24 hours a day) and public holidays are also considered off-peak periods for both power and energy.
*Schedule applicable to Peninsula and Islands. Ceuta and Melilla have their own schedule, which you can see here [downloadable file]
New 2.0TD rate
All customers who had a version of a 2.0 or 2.1 tariff (A, DHA and DHS) will be switched to the toll structure known as 2.0TD, with the following characteristics:
- 2 energy periods, with the option to have different power rating in each period. On 1 June, the power in both periods will stay the same, but you will be able to choose two power periods (the same or different) optimised for your personal requirements.
- 3 energy periods. For your convenience, Iberdrola will maintain the same energy periods applied to your current bill, such as, for example, the offer period in your Made-to-Measure plan. However, if you prefer, we have contracts with the three energy periods with the new toll tariff.
The energy and power prices must be updated to comply with the requirements of the new regulations, which is why customers must be notified of any upward or downward variations, for accurate information. These changes mean that the price of the power term (fixed) is going down, while the energy term (variable) is going up, so generally speaking your energy bill will not change by too much. However, our customers need not worry about anything, because all these changes are made automatically.
These changes are designed to encourage responsible energy use by giving customers more control over their electricity bills and the ability to influence the variable part of the bill by using more efficient electrical appliances and adopting routines that reduce energy use. It is also more conducive to the integration of emerging technologies like electrical mobility and self consumption.

Main changes
The main change is the restructuring of all the periods and schedules for customers with a power rating over 15 kW and High Voltage. These new schedules include the "seasonal" concept, consisting of different months of the year, and also introduces changes by geographical location. Another very significant change is the new billing for the power rating which we will explain below.
New hourly distribution for 3.0TD and 6.XTD tariffs
The new 3.0TD and 6.XTD share the same schedule and are defined by season (groups of months), the day of the week, the time of day and geographical location. What's more, the time periods will be the same for both power and energy. For the Peninsula* the schedule is:
Additionally, weekends (24 hours a day) and public holidays are also considered off-peak periods for both power and energy.
*Schedule applicable to the Peninsula. Canary Islands, Ceuta and Melilla have their own schedule, which you can see here [downloadable file]
New 3.0TD and 6.XTD
All customers with a 3.0A tariff will have a 3.0TD tariff and customers with a 3.1A or 6.XA will have a 6.XTD tariff according to the voltage. Both these tariffs will have the same characteristics:
- 6 power periods with contracted power rating, the same or different, in each period. The periods must be in "ascending order" so that the contracted power for each period is equal to or higher than the previous period. The change from the three current power ratings to the new 6 power ratings will be carried out as established in Circular 3/2020.
- 6 energy periods which, like power, have different times for each month and day of the week.
With regard to power billing, from 1 June, the power to be billed is always the contracted power rating and only in the event of a higher power demand will it be billed as excess power. This excess use will be billed as an independent item, called "Excess Power Term".
Energy periods and power must be updated to comply with the requirements of the new regulations, which is why customers must be notified of any upward or downward variations, for accurate information. These changes mean that the price of the power term (fixed) is going down, while the energy term (variable) is going up, so generally speaking your energy bill will not change too much. However, our customers need not worry about anything, because all these changes are made automatically.
These changes are designed to encourage responsible energy use by giving customers more control over their electricity bills and the ability to influence the variable part of the bill with improvements in business efficiency and adopting routines that reduce energy use. It is also more conducive to the integration of emerging technologies like electrical mobility and self consumption.
