Earlier this month, Southern California Edison’s outage map again showed Public Safety Power Shutoff (PSPS) warnings across the Santa Barbara South Coast, from the Gaviota Coast to downtown Santa Barbara.

High heat, dry vegetation, and elevated fire risk are recurring realities here. For residents who have lived through wildfires, wind events, and days-long outages, the warnings are familiar.

They are also reminders of how vulnerable our region’s electricity supply remains.

Santa Barbara’s energy vulnerability runs deeper than most residents realize. The South Coast sits within what energy planners call the “Goleta Load Pocket.”

Our electricity reaches us through a transmission corridor that crosses roughly 40 miles of mountainous, fire-prone terrain.

The region does not have a fully independent backup transmission route. When wildfire or extreme weather threatens that corridor, a single event can place electricity service for a large portion of the South Coast at risk, which is why the utility shuts off power to tens of thousands of customers at once.

It’s not a flaw in the system. It is the system.

Now, another weather concern is developing.

Climatologists are tracking what may be one of the strongest El Niño events on record. On Sept. 10, NOAA’s Climate Prediction Center reported that El Niño is strengthening, with a greater than 90% chance of becoming a very strong event this fall and winter, 2026-27.

NOAA also predicts a 75% chance that this year’s El Niño could exceed the strength of previous El Niño events dating back to 1950.

El Niño does not guarantee a wet winter in Southern California. But an event of this magnitude increases the likelihood of significant weather impacts, including storm-related power disruptions, flooding risk, fallen trees, damaged electrical equipment, and the same infrastructure vulnerabilities that every major weather event exposes.

For homeowners who have been weighing solar and battery storage, the relevance expands beyond any weather forecast. A well-designed battery system keeps a home running when the grid goes down, whether the cause is a PSPS event in September or a winter storm in January.

That can mean continued refrigeration, lighting, internet access, and power for medical equipment when the surrounding neighborhood is dark.

Yet just as energy resilience is becoming more valuable, one of California’s longest-standing protections for solar homeowners is about to disappear.

Since 1980, California has maintained a property tax exclusion for homeowners who install solar and storage.

Under Proposition 13, adding a major improvement to a home — a pool, an addition, a new structure — adds the value of that improvement to your property’s tax assessment, on top of your home’s existing base value.

Section 73 of the Revenue and Taxation Code carved out an exception for solar: The installation does not count as newly constructed for tax purposes, and does not trigger a reassessment.

It has been quietly saving solar homeowners money for 46 years. That protection expires on Jan. 1, 2027.

Assembly Bill 2389, which would have extended the exclusion through 2031, was held under submission in the Assembly Appropriations Committee in May, a procedural move that effectively stalled the bill.

Lawmakers did provide some protection for systems already installed. SB 710, signed last year, protects homeowners who already have solar by permanently locking in their exclusion regardless of when the sunset takes effect.

However, that protection lasts only until the property changes ownership.

For anyone who has not yet installed solar and storage, the clock is running.

The deadline is also closer than it sounds. Under California property tax law, what qualifies a solar system for the exclusion is passing inspection with the local authority having jurisdiction, not simply signing a contract.

Permitting, installation, and final inspection all need to be completed before Dec. 31.

Inspection schedules often become congested near the end of the year. With a Super El Niño forecast bringing heavy rain to Southern California this winter, installation schedules in the final weeks of the year are likely to face additional disruption.

Homeowners in this region are accustomed to making do. Generators run during outages.

People fill bathtubs before storms. Community resource centers open in Goleta parking lots when the power goes out for days at a time.

But there is a difference between preparing for disruption and reducing dependence on the system that creates it.

Solar and battery storage do not eliminate vulnerability, but they give homeowners a meaningful degree of control over what happens inside their own homes when the grid cannot deliver.

The incentive landscape for that choice has narrowed considerably. The federal residential tax credit expired at the end of 2025. Local battery rebate programs are currently paused.

And the property tax exclusion, which is the longest-standing financial protection for solar homeowners in California, is now set to expire in fewer than four months.

For homeowners weighing the decision, the question is no longer whether conditions are getting more challenging. They clearly are.

The question is what to do about it.

The Active Solar Energy System Exclusion is governed by Section 73 of the California Revenue and Taxation Code. AB 2389’s legislative status can be tracked at leginfo.legislature.ca.gov.
