WEG participated in the development of the new Los Cabos desalination plant in Mexico, supplying a complete package of electrical, automation, and systems solutions for ACCIONA, a global leader in sustainable water infrastructure. 

The project represents an important step forward in ensuring drinking water supply for the Cabo San Lucas region, which faces ongoing challenges in meeting the population’s water demand. The new plant will have a production capacity of 250 liters per second of drinking water — equivalent to 21,600 m³ per day — helping to meet projected demand over the next 20 years and benefiting more than 464,000 residents. 

Using reverse osmosis technology, the system was designed to ensure operational efficiency, reliability, and sustainability throughout the seawater desalination process. The infrastructure also includes a submarine outfall for brine discharge back into the ocean and an open seawater intake system. 

To meet the plant’s requirements, WEG supplied a broad portfolio of integrated equipment and solutions, including transformers, medium-voltage switchgear, motor control centers, electrical panels, automation systems, variable frequency drives, electric motors, and UPS systems. 

Among the supplied equipment are: 

  • 8 substation-type transformers rated at 3,000, 500, and 250 kVA;  
  • 15 AIS medium-voltage switchgear columns, model CCW07;  
  • 21 low-voltage distribution panels ranging from 1,600 A to 4,000 A;  
  • 24 CCMX02 motor control center columns;  
  • 7 Distributed Control System (DCS) panels;  
  • Panels incorporating 95 variable frequency drives and soft starters;  
  • 4,000 A busway for interconnection between the transformer and the distribution panel;  
  • 55 low-voltage motors;  
  • 3 UPS systems.  

Although it is a smaller-scale facility within the desalination segment, the project demonstrates WEG’s technical capability to supply virtually the entire electrical and automation infrastructure required for this type of critical application. 

This supply also represents the largest scope ever developed by WEG’s Automation and Systems business in Mexico, strengthening the company’s presence in strategic infrastructure projects and reinforcing its position as a global provider of complete solutions for water, energy, and industrial automation. 

With this project, WEG reaffirms its commitment to technologies that drive sustainable development, expand access to safe drinking water, and contribute to improving the quality of life of communities.
