PG&E’s Electric Operations executive vice president Geisha Williams said: "These new substations will enable PG&E to continue to provide safe, reliable, affordable and clean energy to our customers in the greater Bakersfield and Morgan Hill areas.

"The investments in these communities will be key to helping enhance our region’s continued success and the state’s long-term economic vitality."

Planned to be built at Wheeler Ridge Junction, the new high voltage substation will help enhance electric service reliability in Bakersfield, especially in the hot summer months when demand for power is higher.

The new Spring substation will boost service reliability as well as provide additional grid resiliency for customers in the Morgan Hill area.

The two projects are scheduled to be commissioned in 2020 and 2021, respectively and are due to undergo an approval process by the California Public Utilities Commission.

The substation projects have been approved by the CAISO during its annual Transmission Planning Process in 2014.
