HV Substation Guindo and Pueblo Seco in Chile

In February 2019, ANDRITZ signed a contract for electro-mechanical equipment for two High Voltage Substations GUINDO 220/66 kV and PUEBLO SECO 154/23 kV in Chile with Besalco Energia Renovable.

The scope for ANDRITZ includes design, engineering, special studies, supply as well as supervision of installation, test on site and commissioning of the complete electro-mechanical equipment including primary equipment, power transformers, control and protection, tele-communication and distribution. The project will be executed by a consortium of ANDRITZ Hydro Italy and ANDRITZ Chile.

The Guindo project is situated very close to the town of Concepcion and will cut the existing transmission lines 1 x 220kV Lagunillas-Hualpen and 2 x 66kV Coronel-Concepcion while Pueblo Seco is situated close to the village of Pueblo Seco and will cut the existing transmission line 1 x 154kV Charrua-Monterrico. The Chilean government through the National Electric Coordinator (CEN) projected an expansion of the national electrical grid in order to be able to meet the continuously growing demand of energy. With these orders, ANDRITZ, thanks to their large experience in HV substations, strengthens its presence in the Chilean Transmission Market.

The commissioning of the Guindo substation is scheduled for the first months of 2021. The Pueblo Seco substation will commence commercial operation at the end of 2020.
