Electricity costs don’t stay flat. Over decades, rates have steadily climbed across the U.S., and California is no exception. For homeowners considering solar, understanding how fast utility prices rise helps you forecast your true savings—and why acting now matters more than ever.

Historical Increase: How Much Do Electric Rates Go Up Yearly?

  • Nationally, electricity prices have increased by an average of about 2.85% per year over the past 25 years.
  • In California, rate increases have outpaced the national average. Some analyses report average annual growth in the 3.7%–4.5% range for recent decades.
  • In fact, California is frequently listed among the states with the highest long-term rate increases.

Because utility rates compound, even small annual increases accumulate significantly over 10–20 years.

Why California’s Rate Increases Are Steep

Several local factors drive steeper increases:

  • Wildfire mitigation & safety upgrades: Utilities invest heavily in infrastructure, vegetation management, and grid hardening, passing costs to customers.
  • Grid upgrades & aging assets: Maintenance, replacement, and technological upgrades push rates upward.
  • Regulatory and subsidy structures: Programs supporting lower-income customers, solar export credits, and other mandates shift costs across customer classes.
  • California’s high base cost: California already has some of the highest rates in the U.S., so additional increases hit harder.

The Impact: What That Means for Homeowners

When electricity rates rise:

  • Your monthly bill increases even without changing usage.
  • The value of a solar system (in offsetting costs) increases accordingly.
  • Delays in going solar mean you miss out on years of compounding savings.

For example: If your current rate is $0.30 per kWh, a 3% annual increase means in 10 years, that rate becomes ~$0.40 per kWh. Over thousands of kWh per year, the difference is large.

Positioning Solar as Your Hedge

Solar + battery systems help protect you against future rate hikes. Here’s how:

  • Fixed-cost production: Once installed, your energy from solar is “free” beyond maintenance, insulating you from utility escalations.
  • Compounding benefit: Every year utility rates rise, your savings (versus paying the utility) grow.
  • Better ROI projections: Solar quotes that assume static rates often undervalue real savings. Use reasonable escalation (3–4%) to model a truer payback period.

Call to Action (Tailored for You)

Don’t let rising utility rates eat into your earnings from solar. Secure your future energy savings now—before the incentives phase down and rates climb even more.
