Contracted power review in Seville, Spain: pay only for the potencia you use

Contracted power review in Seville, Spain: a saving that does not depend on using less

On a Spanish electricity bill you pay for two things: the energy you consume and the power you have contracted, whether you use it or not. That second item is the potencia contratada, the maximum power in kW your home can draw at once. A contracted power review in Seville, Spain matches it to what your home really needs. On the 2.0TD tariff the power charge costs roughly 30 euros per kW per year in access tolls, so having 2 kW too many means paying every year for nothing. Having too little means the supply cuts out every time the oven, the washing machine and the air conditioning coincide.

How power works on the 2.0TD tariff

The 2.0TD is the standard tariff for homes and small supplies in Spain. In practice:

• Two power levels: one for the peak period (P1) and one for the off-peak period (P2). They can be different.
• Off-peak (valle) includes nights, from 0:00 to 8:00, and weekends, when it is usually cheaper to charge the car or run appliances.
• The limiter, the old ICP now built into the smart meter, cuts the supply when you exceed your contracted power. Everything goes off, you unplug the kettle and press the button on the meter: most foreign residents live that scene in their first week.
• Common steps: 4.6 kW, 5.75 kW, 6.9 kW or 9.2 kW, among others.

Access tolls and charges are set by CNMC Circular 3/2020 (the Spanish energy regulator) and Royal Decree 148/2021.

What we do

1. We review your bills and the power contracted in each period.
2. We measure your real peaks with a monitor in the consumer unit for a few days, day and night. If you want to keep watching afterwards, we leave it installed with its app: see energy monitoring.
3. We check the installation: main switch, individual supply cable (derivación individual) and consumer unit, in case anything needs upgrading before an increase.
4. We recommend the peak and off-peak power, with the annual saving or cost of each option.
5. If you need more, we issue the boletín and deal with the distributor through increase contracted power.

Typical cases in Seville

• Flats in Nervión or Triana with power contracted decades ago that nobody has reviewed: sometimes there is too much and sometimes the limiter trips every summer.
• Homes in Sevilla Este or Dos Hermanas moving to induction and aerothermal heat pumps: before increasing blindly, measure.
• Houses with an electric car in Mairena del Aljarafe or Alcalá de Guadaíra: raise only the off-peak power, or charge with dynamic load balancing without touching the power.
• Holiday homes used part of the year, where the power was set for a family that no longer lives there and is paid for every month.

Tariff and time periods

As well as the power, we go through which periods you consume in, so you can move whatever possible to the off-peak hours: washing machine, dishwasher, water heater or charging the car. The 2.0TD has peak, standard and off-peak energy bands (punta, llano and valle). We give you your consumption by period so you can compare tariffs from different suppliers (comercializadoras) with good judgement. For businesses, power is studied as part of an energy audit, and if you want to cut the energy part of the bill too, look at solar panels.
