The Future of Renewable Energy in San Diego: Trends and Predictions

San Diego has always had a paradox at the heart of its energy story: some of the best solar resources in the country, paired with some of the highest electricity rates. That combination has shaped how homeowners and businesses approach renewable energy here, and it's likely to keep shaping what comes next. Here's a look at where things stand and where the region's renewable energy landscape appears to be heading.

Battery Storage Has Moved From Optional to Essential

Perhaps the biggest shift in recent years has been the growing role of battery storage. Since California's transition to its current net billing structure for new solar customers, exporting excess solar power to the grid earns significantly less than it used to, while buying electricity back from the utility remains expensive.

That gap has made pairing solar with a home battery, rather than installing solar alone, the far more common approach for new systems, since it lets homeowners store and use their own power during expensive peak hours instead of selling it cheaply and buying it back at a premium.

Expect this trend to continue. As more homeowners install storage, San Diego is likely to see battery systems increasingly used not just for savings, but for resilience, keeping essential circuits running during outages, wildfire-related power shutoffs, or grid strain during extreme heat events.

Rising Electricity Rates Are Reshaping the Economics

San Diego Gas & Electric's rates remain among the highest in the nation. While that's a real cost burden for ratepayers, it also means the math behind going solar, particularly solar paired with storage, continues to make sense for many households and businesses, even as federal incentive programs shift over time. As rates continue to climb, expect solar-plus-storage adoption to keep growing as a way for property owners to gain more control over their energy costs.

EV Adoption Is Driving New Infrastructure Needs

As more San Diego homeowners and businesses adopt electric vehicles, demand for home and commercial EV charging infrastructure continues to grow alongside it. This is increasingly intersecting with solar and storage decisions, since charging an EV directly from home solar production, rather than pulling entirely from the grid, adds another layer to the savings equation. Multifamily properties, workplaces, and retail locations are also expected to continue expanding charging infrastructure to meet growing demand from residents, employees, and customers.

Policy Continues to Evolve

Renewable energy policy at both the state and federal level has changed meaningfully in recent years, from adjustments to how solar exports are credited, to shifts in available tax incentives and storage rebate programs. These policies directly affect project economics, so what makes sense for a given property can shift over time as programs are updated or phased out. For homeowners and businesses considering a project, working with a contractor who stays current on these changes, and can explain how they apply to a specific situation, is increasingly valuable.

What This Means for San Diego Property Owners

Taken together, these trends point toward a renewable energy landscape that's less about simply "adding solar panels" and more about designing an integrated system, solar, storage, and increasingly EV charging, tailored to how a property actually uses energy. That shift rewards property owners who plan holistically rather than treating each piece as a separate decision.
