How to Upgrade an Electricity Supply


UPGRADING AN electricity supply is required when you need more power than you are currently contracted for with Iberdrola, or your electricity supplier. This is evident when the electricity supply constantly cuts off when using electrical appliances. This is caused by having too many switched on at the same time, and this produces an overload to the system. It indicates that the amount of electrical power required to work all of the appliances is insufficient for your consumption needs. Hence you need to upgrade the electrical installation in order for Iberdrola to permit an increase to the contracted power supply. 

Your contracted power supply (potencia contratada) is stated in kilowatts (kW) on your contract and electricity bill. This is the amount of electrical power that you sign up for with Iberdrola, when moving in to the property. It is the maximum amount of electrical power you are allowed under the terms and conditions of your contract. A standing charge for the contracted power supply is calculated by the contracted power supply x the daily supply rate (€/kW dia). The more power that you are contracted for, the higher the standing charge will be. 

ICP penalty charge for  a 3.3 kW contracted supply 

The contracted power supply is controlled by a power limiter switch called an Interrupter de Control de Potencia, most commonly referred to as an ICP. Failure to comply and fit an ICP, if instructed to do so by Iberdrola, will result in a penalty charge on your electricity bill. Currently there are three types of ICPs for domestic dwellings in operation: 

ICP(M)
1. ICP(A) – old automatic type, housed in the meter cupboard (discontinued) 

2. ICP(M) – manual type, housed in, or next to, the Consumer Unit (current) 

3. ICP(A) – automatic type, integral part of the new digital Smart Meter (new) 

Smart Meters will replace the traditional electric meters all across Spain by the end of 2018. They are fitted with an integral ICP, which will supercede the old ICP(A) and ICP(M), making them redundant. A possible consequence of having a Smart Meter fitted may result in owners having to arrange an upgrade to the electricity supply. The introduction of Smart Meters prevents the malpractice of illegal upgrades. 

An illegal upgrade is one where the ICP has been subject to tampering. It will have been disconnected, by-passed or changed without the authorisation of Iberdrola, normally evident by the seal being removed or tampered with on the ICP box, next to, or part of, the Consumer Unit. To legally upgrade an electricity supply an electrician must be employed to supply a BIE aka boletin (electrical installation certificate). The boletin is then presented to Iberdrola so that a new contract for an increased power supply can be arranged. The boletin is also presented to the regional industrial department of the government by the electrician. 

New homes built after 2003 are generally provided with a 5.5 kW or 5.75 kW (25 Amps) contracted power supply on completion, which is generally a sufficient amount of electrical power for running an average home. This is arranged by the developer, and it is currently the minimum requirement by regulation for a domestic dwelling. If an owner requires additional electrical power, then the onus is on them to arrange an upgrade. 

Homes built before 2003 had a minimum requirement of 3.3 kW (15 Amps), and are generally those which need to upgrade their electricity supply. This was the minimum amount developers were obligated to provide before the current regulation, and again, it would be up to the owner to arrange a power supply upgrade if required. This low amount of contracted power can cause a lot of overloading problems with the ever increasing demand of new electrical appliances. To give you a better idea of the problem, a 15 Amp electricity supply is 75% less than the standard 60 Amp electricity supply you would receive in a UK home. It’s not uncommon for old properties in rural areas to have a 2.2 kW, a 1.5 kW, or even a 1.0 kW contracted supply. Running a modern day home in Spain with only 3.3 kW or less electric power available is practically impossible, and those who do, have to supplement gas appliances for cooking, heating and the production of hot water. 

Smart Meter alongside traditional electric meter

A legal contracted power supply for an electrical installation is one where the rating of the ICP(M) or ICP(A) does not exceed the amount stated on the contract. For an installation where a Smart Meter is fitted, the legal process for contracted power is done automatically. 

If you currently still have the traditional electric meter and are on a contracted supply of 3.3 kW or less, you should evaluate your electricity consumption to consider whether or not to upgrade your electricity supply in the near future. The automatic ICP in a Smart Meter, operates digitally with zero tolerance, unlike the IPA(M). Once your Smart Meter is fitted, you may find out that you are not contracted for sufficient electrical power to run all of your appliances.

Warning: Do not allow unqualified persons to upgrade Circuit Breakers. Only a trained professional will understand the correct circumstances when a Circuit Breaker can be upgraded. Insurance companies will not cover claims for an electrical fire proven to be caused by an illegal upgrade. An authorised upgrade must be covered by a valid boletin.

    Can see the new smart meters causing a few problems with the automatic ICP tripping out and the meter in a locked meter cupboard in the street that only Iberdrola can open!

  2. The "Iberdrola padlock" causes a lot of confusion for consumers and their rights. Meter cupboards are not the property of Iberdrola, the ownership and responsibility is shared equally by the consumers whose meters are in the cupboard. The only equipment in the cupboard owned by Iberdola is usually the electric meter, and new legislation now allows you to own your own meter, ending the exclusive right of Iberdrola from renting meters to consumers. Consumers have the right to access the cupboard, and are quite within their rights to remove the padlock. In fact, if you contact Iberdrola because you need access to the cupboard, that's what they tell you what to do.

  3. I have been through the upgrading process in a 10 year old house, from 3.3kw to5.75kw;it cost 600 euros, involved new cabling etc. However when I spoke to a neighbour on the same urbanisation, he said he merely asked Iberdrola for a new dual tariff meter, and they installed it a and changed the tariff to 5.75. Alocal electrician put in a sronger fuse for 30 euros. no boletin , no modifying work in the house;how can this be done when i paid all that money?

  4. It is not possible to have a power supply legally upgraded without obtaining a new boletin. Your neighbour has employed the service of someone who obviously misled him and probably could not arrange a boletin. Any cowboy can change a fuse (CB) !!!

  5. Furthermore, the neighbour will be downgraded back to 3.3 kW when the ICP becomes operational in his Smart Meter.

  6. 600 euros does not sound unreasonable to upgrade from 3.3kW to 5.75kW when taking into account the work involved, the cost of the boletin, and Iberdrola's charges.

  7. Electrical certificates must be obtained regularly to ensure that electrical appliances and your property’s wirings are able to meet the standards that guarantee their safety and optimum performance.
