Investments to strengthen the network in the Polígono Sur
Endesa allocated nearly €2.5 million in actions to improve the quality and security of electricity supplies in the Polígono Sur Industrial Estate in Seville in 2022. These investments in the Low- and Medium-Voltage networks were undertaken not only to ensure the supply to customers, but above all to protect them from the serious consequences resulting from the manipulation of distribution networks, something which has become a reality in this part of Seville.
The saturation of the networks causes the fuses in the installations to blow in order to protect the people who live in these areas, which is why Endesa made this investment effort to strengthen this safety by renovating the electricity infrastructure.
In this regard, Endesa acted in this area by undertaking 21 civil-engineering works that enabled the strengthening of 23.3 kilometres of medium- and low-voltage circuits. This was in addition to the improvement of 9 transformers and the installation of a new transformer in the Ronda Nuestra Señora La Oliva.
These actions were in addition to those undertaken by the company in 2021:
- Increase in the power at 6 transformer centres that increased from 1,000 KVA of power to 2,000 KVA each.
- Channelling of 8 kilometres of low-voltage cabling and 2 kilometres of medium-voltage cabling.
- Installation of 6 remote controls, to digitalise the transformation centres so immediate action could be taken in the event of an incident.
- Repair of the Martínez Montañés transformation centre as a result of the fires suffered in July and November 2021. Almost all the installation's elements were replaced, including the Medium-Voltage cells, the two 1,000 kVA transformers, the telecommunications cabinets and the medium- and low-voltage cabling.
In addition to the investment in the maintenance and development of the network, Endesa also allocated very large amounts to the repair of sabotaged installations, which sometimes involved the complete replacement of the electrical infrastructure following the fire caused by overload, as in the case of the 4 transformation centres that caught fire in the Polígono Sur in 2022.
In addition to these investments in these areas of Seville, Endesa is also working at the institutional level, since the problem is not so much network deficiencies, but rather a much more complex problem that requires the participation of all institutions.
In this regard, Endesa is participating in all the initiatives and working groups called by the Regional Government of Andalusia, the Government Sub-delegation, the Commissioner for the Polígono Sur and the City Council of Seville to try to alleviate the problem of supply cuts, as well as to seek joint solutions giving priority to the most critical cases.
Safety of the installations and personal safety
Illegal hook-ups are made using unsuitable materials and without complying with any type of safety standards. Homes with illegal connections do not have the basic protection systems that every home should have. In areas where massive illegal connections are recorded, the only protection that would work is that provided by Endesa's networks, but these are also boycotted so safety for both people and the environment is eliminated.
