​System improvements at Kelker Substation   

  by  Ellen T.  on  5/24/2018

 

Moving an object that weighs 355,000 pounds is no small feat.

In April we transported a new autotransformer to the Kelker Substation for installation. After completely installed, it will weigh more than half a million pounds.

This enormous piece of equipment is an important addition to our electric system. Not only can it carry one third of our system’s peak load, it is also a necessary component of multiple transmission solutions that allow for the retirement of the Martin Drake Power Plant. 

 

What does a transformer do?

After electricity is produced at a power plant, a transformer increases the voltage of the power to allow for efficient travel on transmission lines across long distances to substations and regional interconnections.

Once at the substation, another transformer reduces the high-voltage electricity to allow it to safely enter local, or distribution, lines that serve homes and businesses.




The addition of this autotransformer to the substation will allow us to maintain North American Electric Reliability Corporation compliance and maintain a high standard of reliability and performance.

This new autotransformer will be crucial to the operation and reliability of our system for more than 40 years.
