California public power utility Imperial Irrigation District is investing approximately $23.5 million to replace aging transformers in the Coachella Valley, strengthening electric reliability, reducing the risk of equipment-related outages and preparing the system to meet customers’ growing energy needs.
The projects include transformer replacements at Monroe Substation, North La Quinta Substation, and the Coachella Switching Station. The work will replace aging equipment that has served customers for more than 30 years as part of IID’s long-term infrastructure planning.
“This is exactly the kind of proactive work that supports reliable service for our customers,” said IID Board Chairwoman Karin Eugenio. “By replacing aging transformers before they become a larger issue, IID is investing in the infrastructure our communities depend on, especially during the hot summer months when reliable power is most critical.”
The transformer replacement projects align with IID’s Powering Our Community Together initiative, which focuses on strengthening the electric system, modernizing infrastructure and supporting reliable public power service across IID’s energy service area.
Transformers are essential pieces of equipment that help move electricity safely and reliably through the grid. Replacing older transformers helps maintain system performance, supports growing energy needs, and reduces the risk of equipment-related reliability issues over time.
The work includes projects at Monroe Substation Bank 1 and Bank 2, North La Quinta Substation Bank 1 and Coachella Switching Station Bank 1. Due to long equipment lead times, engineering, procurement and construction work will occur over multiple years, with the projects expected to be placed into service between 2028 and 2029.
“These investments may not always be visible to customers, but they are critical to keeping the electric system strong,” Eugenio said. “As a community-owned public power utility, IID is planning ahead and making responsible investments that support reliability today and for years to come.”
IID said it will continue advancing infrastructure projects that improve reliability, address aging equipment, and support the long-term needs of customers in the Imperial and Coachella Valleys.
