Enhancing grid reliability with a prefabricated control building solution

As utilities continue to modernize aging infrastructure, substation upgrades play a critical role in improving reliability, safety, and overall system performance. Replacing legacy assets with fully integrated, modern control systems allows utilities to better manage growing demand while reducing the risk of outages and operational inefficiencies. This project represents a key step in enhancing the capability and long-term resilience of an existing substation.

Manufacturing a fully integrated control building is a significant undertaking—but delivering a drop-in-place 24’ x 60’ split control building for a utility customer takes it to another level.

Built and fully tested in a controlled factory environment, this approach ensures all systems are verified prior to delivery, reducing onsite commissioning time and minimizing risk during installation.

That’s exactly what Crown Technical Systems delivered for a Southern California utility project. Fully assembled at our Fontana, California facility, this 24’ x 60’ control building was designed as a complete, factory-integrated solution—featuring 11 control panels and ready for immediate deployment.

Utilizing a split-building design, the structure was optimized for transportation and enabled rapid, efficient onsite assembly, minimizing installation time and disruption to the existing substation. This project reflects Crown’s commitment to delivering reliable, fully integrated solutions that help utilities modernize infrastructure and meet the evolving demands of the grid.
