Boletín eléctrico in Tomares, Seville, Spain: more power, pools, three-phase and new homes

Boletín eléctrico in Tomares: almost always a villa that has grown

Tomares has about 25,492 residents and is a town of villas and townhouses on their own plots, high on the Aljarafe ridge next to Triana and Los Remedios. Many estates, such as Aljamar or those around El Zaudín, were built between the 1980s and 2000s with wiring that was correct for its time but certified for far less consumption than today. That is why the boletín eléctrico, the official installation certificate the distributor relies on, rarely comes here with a change of account holder and nearly always with an extension.

More power for the summer

The most common Tomares case: air conditioning in every room, pool pump, induction hob and now an electric car. The potencia contratada, the maximum power in your contract, falls short, the limiter cuts out in August and, to raise it above what the old boletín states, a new one is needed. Before signing it we check:

1. That the riser cable (derivación individual) from the meter can carry the new power.
2. That the main switch (IGA) is rated for it.
3. That the fuse board has the RCDs and circuits the regulations require.

If any of these fails, we give you its price first. The process is explained on our increase contracted power page.

Three-phase for heat pumps and faster charging

Some large villas need to switch to three-phase supply for a powerful aerothermal heat pump or to charge a car at 11 kW. It changes the riser, the board and the contract, and it is always certified. The charger itself is covered on our home EV charger for houses page.

The pool: an alteration and sometimes an inspection

Refurbishing the pump panel, adding a pool heat pump or switching the pool light to 12 V LED are alterations that get certified. It is a good moment to check the equipotential bonding required by ITC-BT-31, often missing in older pools. If the pool exceeds 10 kW, regulation ITC-BT-05 also requires an inspection by an authorised body. Everything electrical about pools is on our swimming pool electrics page.

Solar panels: a certificate of their own

With so many free roofs, Tomares sees plenty of self-consumption installations. They carry their own certificate, separate from the home’s boletín. If installing them changes the board or raises the power, each part is documented. More on our solar panels page.

Altos del Aire: new flats with a garage

Up beside the Olivar del Zaudín park, the Mistral, Siroco and Poniente phases of Grupo Insur’s Altos del Aire are handed over with their certificate, so none is needed to connect the supply; a new boletín appears when the owner adds a charger in their space, extends circuits in the kitchen or on the terrace, or wants more power than certified. More about the area on our Altos del Aire new-build page.
