IBERDROLA COMPLETES THE FIRST STAGE OF THE EXPANSION OF THE SIGÜENZA SUBSTATION
As part of its commitment to improve service quality
- The Company, which has connected the new 66 and 20 kilovolt switchgear modules to the grid, already has in place the infrastructure that will house the new 20 megavolt ampere transformer
- The new substation will improve service quality for around 10,000 customers in the northern area of the province of Guadalajara
IBERDROLA has completed the first stage of the expansion of the Sigüenza substation, in the province of Guadalajara, which involves the installation of a new 20 megavolt ampere (MVA) transformer and the upgrading of the 66 and 20 kilovolt (kV) systems.
Following this project, which has consisted of connecting the new 66 and 20 kV switchgear modules to the grid, IBERDROLA has in place the infrastructure needed for installing the new transformer, which will increase the service quality offered to its customers and guarantee supply during peak demand times.
Specifically, this power increase will improve the supply quality for around 10,000 customers in Sigüenza, Atienza and Mandayona, among other towns, and will guarantee the transmission of the energy produced at the special-scheme generation plants in the area.
For upgrading the facility, IBERDROLA has used cutting-edge technology and invested a total of 2.6 million euros.
Thanks to an extensive distribution grid, IBERDROLA operates around 92,000 supply points in 130 municipalities across the province of Guadalajara. Specifically, it has 11 substations, over 1,200 transformer stations, and almost 1,700 kilometres of overhead and underground medium- and high-voltage power lines.
Thanks to the power distribution investments made by IBERDROLA in this region, the quality of the supply in Castile-La Mancha is among the highest offered by the Company in Spain. Last year, the Company achieved the highest index of its history with a SAIDI (system average interruption duration index) of 55.6 minutes, a 27% improvement over 2011.
The Company serves around 700,000 customers in Castile-La Mancha and has an extensive distribution grid, comprising over 60 substations, around 8,000 transformer stations, 2,500 kilometres of ultra-high and high-voltage power lines, approximately 12,000 kilometres of medium-voltage power lines, and 10,000 kilometres of low-voltage power lines.
