To support the growing Auburn community, CHELCO has added a mobile substation to increase capacity at the existing site. Because CHELCO is a winter-peaking system, electricity demand is highest during colder months when members rely most on heating. The mobile unit will ensure we can continue serving members reliably during these peak times.

This added capacity also provides peace of mind during unexpected events. Earlier this year, in January 2025, our area experienced a rare snowstorm that pushed the system to its limits. By adding extra capacity ahead of this winter, we’re making sure Auburn has the flexibility to handle similar challenges and keep power flowing no matter the conditions.

While the mobile substation supports the existing site, CHELCO, in partnership with PowerSouth Energy Cooperative, is also investing in a long-term solution—the construction of a brand-new substation in Auburn. 

This project represents a major investment in reliability and will nearly double the capacity of the current substation. That means Auburn will be better prepared not only for today’s peak demand but also for future growth as the community continues to expand.

“These kinds of proactive improvements are essential as our service area grows,” said CHELCO CEO Steve Rhodes. “They help us serve our members today while building a stronger, more resilient system for tomorrow.”

Preparations for the new substation are already underway and scheduled for completion in December 2026. Until then, the mobile substation will continue to support the current site, ensuring Auburn members receive safe and reliable power.
