Golden State Water Takes Proactive Approach to Limit Impact of Power Shutdowns on Water Service
Wildfires are now a year-round threat in California, and electric
utilities throughout the state are proactively de-energizing
their grids (Public Safety Power Shutoffs) as a measure to
protect communities from danger when conditions present a
heightened wildfire risk.
As a water provider that relies on power to operate our water
systems, Golden State Water Company is investing approximately
$10 million to install 31 power generators throughout the state
to help safeguard against water service interruptions during
Public Safety Power Shutoff (PSPS) events. These new power
generators are being installed at key facilities to supplement
and bolster our existing network of generators throughout Golden
State Water’s systems to provide alternative power during PSPS
In the event of a PSPS, customers will be asked to limit water
use for life-essential purposes. The water system may not remain
fully operational during an extended outage, and the community’s
conservation will help to ensure available water supplies can be
directed to aide firefighting efforts.
What is a PSPS?
A Public Safety Power Shutoff (PSPS) is a safety measure in which
electric utilities may proactively de-energize portions of their
power grid to protect the community from potential wildfire
danger when conditions present a heightened risk. Some factors
that could trigger a PSPS include Red Flag Warnings, forecasts of
sustained gusts and winds, dry fuel conditions and low
How Could a PSPS Impact Local Water Service?
Water providers like Golden State Water rely on electricity to
power portions of our water infrastructure, including wells and
booster pumps that are critical to deliver reliable water service
Our water systems typically rely on water storage tanks to
provide water supply during short-term isolated power outages;
however, a PSPS event can take out the entire power grid serving
a water system and span multiple days before power is restored.
Permanent generators with automatic startup switches located at
key facilities will enhance Golden State Water ability to
minimize water service impacts to the community during a PSPS
