Delivering on the Promise
As the community electricity provider for San Mateo County and Los Banos, WestLight Energy is keeping costs lower, reducing emissions from fossil fuels, and investing in a cleaner future. Here’s what 10 years of progress looks like.
Customer Savings
A decade of helping people save money while improving health & comfort
Customer Stories
Meet the people behind the numbers
Margarita Mendez
“Now we have air conditioning to boot and didn’t have to pay more… that’s like icing on the cake.”
Wayne Szeto
“Our initial motivation to go electric was to really capture some of the cost savings with solar panels.”
Community Reinvestment
A decade of working with local governments & partners to deliver lasting benefits
Community Spotlights
Reducing emissions & saving money in the public spaces where we live, travel & gather
Brisbane Pool Heating System
The first of its kind in the nation, the heat pump electric pool system project reduces the City of Brisbane’s emissions by 86%.
Peninsula Pines Apartments EV Charging
It’s currently the largest retrofit EV charging project at an apartment complex in California.
San Carlos Youth Center goes Solar
Our decade-long partnership with San Carlos has delivered 29 EV chargers and solar on three community buildings.
Solar for Los Banos Community Center
Solar carports provide shade while offsetting 95% of the Community Center’s energy use and saving the city more than $1 million.

Electric Grid Transformation
A decade of investing in the clean energy grid California needs
*Based on existing contracted resources
Clean Energy Portfolio
Building the grid of tomorrow
Over the past decade, our investments have expanded from solar to a more diverse mix of renewable energy and storage—helping provide clean energy when California needs it most.
Together, projects like these help provide clean electricity when and where it is needed most, and replace the use of dirty fossil fuels on the grid.
More Renewable Generation
Wright Solar Park
200 MW solar
Our first major renewable energy project, producing enough electricity annually to power approximately 100,000 homes.
Greater Resource Diversity
SunZia Wind
220 MW solar
Our largest wind investment, adding clean energy from a different region and at different times of day.
Long-Duration Clean Energy
Willow Rock Energy Storage Center
15 MW / 120MWh advanced compressed air storage
Designed to store clean electricity for long periods, helping meet demand when solar production falls.
The Next Chapter: Local Solutions
The electricity system is becoming more connected and more local.
Cleaner energy, closer to home
Cleaner energy, closer to home: Solar and battery systems on homes, businesses, and public buildings generate and store clean electricity closer to where it’s used, reducing strain on the grid and improving resilience.
Smarter homes
Electric vehicles
Responsive local grids
Community microgrids and virtual power plants coordinate local energy resources to improve reliability, reduce emissions during periods of high demand, and make communities more resilient.
Working together, we deliver cleaner air, lower costs, and greater reliability.
Innovation Scaled
From pilots to statewide practice
See how ideas tested in our communities have grown into solutions influencing programs, policies, and clean energy practices across California.
Reach Codes
Helping local governments advance cleaner, all-electric buildings.
LOCAL IMPACT
Supported 18 jurisdictions with technical analysis and implementation guidance.
BEYOND OUR SERVICE AREA
This work helped inform updates to California’s statewide building standards.
Apartment EV Charging
Making EV charging at multifamily properties more practical and affordable.
LOCAL IMPACT
Developed right-sized charging approaches across multifamily properties that maximize the number of chargers at the lowest possible cost.
BEYOND OUR SERVICE AREA
The approach helped influence EV charging programs across California.
Regenerative Braking
Turning energy generated by electric trains into a new clean energy resource.
LOCAL IMPACT
Partnered with Caltrain and San José Clean Energy on one of California’s first programs of its kind, compensating Caltrain for regenerative braking energy returned to the grid.
BEYOND OUR SERVICE AREA
Demonstrated a new model for electrified public transit and clean energy collaboration.
Lower-Cost Electrification
Finding practical ways to electrify homes without costly, unnecessary electrical upgrades.
LOCAL IMPACT
Developed right-sized approaches that help customers electrify while avoiding electrical panel or service upgrades when possible.
BEYOND OUR SERVICE AREA
Helped inform statewide programs and practices designed to make home electrification more affordable and accessible.
