California just hit a jaw-dropping milestone—and it’s a game-changer for solar energy. In late March 2025, the Golden State ran on 100% Wind, Water, and Solar (WWS) energy for 13 straight days. On March 27 alone, WWS output was seven times that of fossil gas, covering 67% of daily demand and peaking at an incredible 130%. At Precis Solar, we’re thrilled to see solar leading the charge toward a cleaner, greener future—here’s why it matters to you.
Breaking Down the Milestone
This isn’t just a feel-good stat. Solar, paired with wind and hydropower, powered homes, businesses, and communities without leaning on dirty fossil fuels. Battery storage—up 74% from 2024—played a starring role, soaking up excess solar energy during the day and delivering it when the sun went down. The result? Fossil gas use dropped 26% year-over-year, proving California’s renewable revolution is hitting its stride.
This milestone ties directly to Senate Bill 100’s goal of 100% carbon-free electricity by 2045, with a big checkpoint of 60% renewables by 2030. Solar’s dominance in this WWS streak shows we’re not just on track—we’re accelerating.
Why Solar Shines Bright
California’s solar boom isn’t slowing down. From massive projects like the 758 MW Eland Solar-plus-Storage site to rooftop systems like the ones we install at Precis Solar, the state added significant capacity in 2025. Batteries are the secret sauce, letting us store midday power to beat those pricey evening Time-of-Use (TOU) rates—think 50 cents/kWh or more from utilities like PG&E. With NEM 3.0 cutting export credits to 5-6 cents/kWh, smart solar setups are all about self-reliance.
This WWS run proves solar isn’t just a trend—it’s a powerhouse. On March 27, renewable output hit 130% of demand, meaning we’re generating more clean energy than we can use in real-time. That’s a win for the planet and a signal that solar’s ready to carry the load.
What It Means for You
This milestone isn’t just for energy geeks—it’s a wake-up call for homeowners. Electricity costs are climbing, fueled by wildfire mitigation (PG&E’s spending $18 billion through 2025), grid upgrades, and growing demand from EVs and data centers. Meanwhile, solar offers a way out:
  • Slash Your Bills: Generate your own power and store it to avoid peak TOU rates.
  • Go Green: Join California’s renewable wave and cut your carbon footprint.
  • Stay Ahead: With storage, you’re not at the mercy of NEM 3.0 or utility price hikes.
At Precis Solar, we’re seeing more Californians embrace solar-plus-storage to lock in savings and energy independence. The WWS milestone shows what’s possible—now it’s your turn to make it personal.
