Investing in a Smarter, More Reliable Grid

When you flip a switch or charge your phone, you’re tapping into one of the most reliable electric grids in the nation. That’s no accident. It’s the result of decades of hard work and innovation.

For 19 consecutive years, SDG&E has earned the prestigious ReliabilityOne® Award for Outstanding Reliability Performance in the Western Region. This recognition reflects our unwavering commitment to keeping the lights on, even as California’s energy landscape grows more complex.

But what does reliability really mean for you?

It means fewer outages, faster restoration times and peace of mind. It means your home stays powered during extreme weather, and your business avoids costly disruptions. In fact, SDG&E’s reliability investments have helped avoid millions in outage-related costs, savings that ripple across our communities.

Innovating for a Stronger Grid

These investments include advanced technologies like automated switching systems that reroute power instantly, power quality tools that prevent outages before they happen and grid modernization efforts that support California’s clean energy integration.

We’re also expanding our network of energy storage systems like the Westside Canal Battery Energy Storage site (BESS), to ensure SDG&E’s electric grid is reliable and leveraging clean, renewable energy.  

SDG&E has recently commissioned microgrid capabilities at the Cameron Corners Microgrid and advanced the Borrego Microgrid to ensure critical facilities, like health centers, schools, fueling stations, public safety and markets to get food and water are online when it matters most.

Building for Tomorrow

In total, SDG&E has 20+ energy storage and microgrid sites with 442 megawatts (MW) of utility-owned energy storage and another 40+ MW in development.

And we’re not stopping there. Every upgrade we make is designed to serve you better, today and tomorrow. Whether it’s undergrounding power lines to reduce wildfire risk or deploying smart sensors to detect issues before they escalate, we’re building a grid that’s smarter, stronger and more responsive.

Because when you pay your energy bill, you’re not just buying electricity; you’re buying reliability. And that reliability saves money, prevents heartaches and keeps life moving safe and uninterrupted. 

At SDG&E, we believe understanding your energy bill shouldn’t be a mystery; it should be empowering. That’s why we’re committed to transparency and to showing you exactly how your dollars are working to deliver dependable energy every day.
