Cranbrook substation upgrade

Upgrading Cranbrook substation for a stronger, more reliable energy future.

Since its establishment in 1972, the Cranbrook substation has served the community well. Now, 53 years later, standards, technology, and network capabilities have advanced.

While the substation has remained resilient, its infrastructure and equipment are reaching the end of their operational lifespan. To ensure the safe, efficient, and reliable delivery of power and to meet the growing electricity demand, we are investing in upgrades.

Cranbrook substation supplies power to approximately 4,800 customers, predominantly residential, with a portion of commercial customers. As part of this project, we will expand the existing substation onto the adjacent Ergon-owned land, with a new, modern building designed for long-term reliability and future growth. This upgrade reflects our commitment to powering the community with stability, efficiency, and sustainability for decades to come.
