Contracted power (potencia contratada) is the amount of electricity you can use at the same time. With induction hobs, air conditioning, electric water heaters and electric cars, many homes in Málaga now find 3.45 or 4.6 kW isn't enough.
Increasing your power isn't just a matter of asking your supplier. Your installation certificate states a maximum permitted power: if the new power exceeds it, the supply line from the meter, the fuse box and the protection devices need checking, and a new certificate must be issued. That's what we do.
Signs you don't have enough power
The main switch trips when cooking
Oven and induction hob together exceed your contracted power.
You can't run the air-con and water heater together
You have to keep switching appliances off so the power doesn't cut out.

An electric car adds 3.7 to 7.4 kW if there's no load management.
You've renovated the kitchen
More powerful appliances than when the installation was done.
You're considering a heat pump
Heat pumps (aerotermia) and electric heating need more power.
Premises with more equipment
Businesses adding cold rooms, ovens or air conditioning.

Standard power levels and distribution company charges
For single-phase 230 V supplies, the usual power levels are 3.45 kW, 4.6 kW, 5.75 kW, 6.9 kW, 8.05 kW and 9.2 kW. The REBT treats up to 5.75 kW as basic electrification and anything above as high-demand, which means additional circuits in the home.
On top of our work, the distribution company may charge access and extension fees when the new power exceeds what was already assigned to your supply. Those amounts are set by regulation and are paid to the company, not to us.
Frequently asked questions
Do I need a certificate to increase my power?
Only if the new power exceeds the maximum permitted shown on your current certificate, or if the installation isn't documented. If your installation can already take the power, you simply ask your electricity supplier for the change.
How much power do I need?
It depends on which appliances you use at the same time. A home with an induction hob, oven and air conditioning usually needs at least 5.75 kW; with an electric car, more, unless the charger has dynamic load management.
Does increasing my power make my bill more expensive?
Yes, the power charge (término de potencia) is a fixed monthly cost. That's why we calculate just the power you need and, if you install a charger, recommend load management so you don't have to increase it as much.
How long does the process take?
Our part (inspection, upgrades and certificate) is usually done within a few days. After that, the electricity supplier and distribution company have their own timescales for activating the new power.
Can I switch to three-phase?
It's possible when you need a lot of power (for example, 11 kW chargers or machinery), but it means replacing the supply line and the fuse box. We assess it on the visit.
