California state government and the climate and environmental communities take great pride in California’s “progress” toward a fossil fuel free clean energy future, as illustrated by the images and text below, recently published on Facebook.

1. California Achieves Record Hours of 100% Clean Energy in Early 2026

In January 2026, California's main grid ran on 100% clean energy (wind, solar, hydro, and other renewables) for a total of 102.6 hours across 22 days—part of a strong start to the year. This continues the state's trend where clean sources met or exceeded demand for portions of the day on most days in 2025 (1,856 hours across 77.3 days). These records highlight California's massive investments in solar, wind, batteries, and grid upgrades, proving reliable 100% clean power is possible and bringing hope for the 2045 goal of zero-carbon electricity!

NOTE: There were 31 days and 744 hours in January, 2026, so 102.6 hours of 100% clean energy is 13% over 71% of the month.

NOTE: There were 365 days and 8760 hours in 2025, so 1856 hours of clean energy exceeding demand is 21% of the year and 77.3 days is not “most of the days in 2025”.

2. California Adds Record Battery Storage Capacity in Late 2025 – Early 2026 Momentum Continues

California reached 16,942 MW of available battery storage by late 2025 (announced at COP30), with additions of ~1,200 MW in just six months—a 2,100% surge since 2019. This record capacity (enough to power ~13 million homes for 4 hours) helped avoid blackouts and enabled more renewable integration. Early 2026 trends show continued growth, positioning California as a global leader in grid reliability and clean energy transition.

NOTE: California annual electricity consumption is approximately 250 TWH, or 250,000,000 MWH. Four hour storage of 16,942 MW equals 67,768 MWH, or less than 1% of the storage theoretically required to support a reliable 100% renewable grid.

3. California's Renewable Share Hits New Highs – Solar and Wind Drive Historic Progress

California's renewable generation (including solar, wind, and other sources) reached 52.3% of the power mix in 2024 (latest full-year data), with non-hydro renewables at 41.3%—the highest annual increase on record. Early 2026 shows continued momentum, with solar and wind output rising and fossil fuel share dropping to record lows (36.3%). This progress, driven by state investments, is reducing emissions and proving clean energy can power the world's 4th-largest economy reliably.

NOTE: California imports approximately 105,000 GWH each year, or approximately 40% of its electricity consumption, of which approximately one third is generated from fossil fuels according to California Energy Commission data.

The images below from the Cal ISO Live Dashboard provide interesting insights into the operation of a renewables intensive, capacity constrained grid. Solar generation dominates the generation mix on most days over the period shown, with the exception of 2/16, during daylight hours. Wind generation was available variably but continuously over the period. Storage provided power each day during the evening “duck curve” peak. Large hydro was also increased during the evening “duck curve” peak. Nuclear, geothermal, biomass and biogas generation operated continually throughout the period. Load following generation was provided primarily by natural gas generation and imports. CA ISO does not estimate the contribution of behind-the-meter solar generation, though it totals approximately 20 GW of generating capacity.

Renewable generation exceeded system load on 2/14, 2/15 and 2/18, reaching a high of 129% of load on 2/14 & 2/15.

CA ISO imported electricity at widely variable rates throughout the period. No power was exported from CA ISO during the period. Imports exceeded 8 GW at peak on 5 of the 6 days, or approximately 25% - 40% of daily peak load.

CA ISO charged and discharged battery storage each day over the period, discharging at rates as high as approximately 8 GW.

CA ISO curtailed renewable generation, mostly solar, on each day during the period, even while storage was being recharged, as shown below. Curtailments peaked at approximately 4 GW on 2/14.

Curtailment - CAISO

California is clearly a long way from an independent, fossil fuel free grid. It relies heavily on imported electricity, much of which is fossil fueled, and remains woefully deficient in storage capacity and deliverability.
