    The Failure of California Electricity Policy, Part 2

    By Carl Wurtz

    When “The Failure of California Electricity Policy In One Image” was published in early April, comments
    left by readers seemed to indicate they had overestimated California’s progress with clean energy.

    That might have been expected; my op-ed had explained why “California just hit 95% renewable energy,”
    a claim made by California’s Independent System Operator (CAISO) last year, was either a distortion, was inept, or was an outright lie.

    This year CAISO offered a followup – but I’ll warn readers, any hope their error would be redeemed would be in vain.
    Our ISO, it seems, has doubled down. It now claims that at 3:40 PM on April 3 of this year,
    electricity on California’s grid had hit “an all-time peak of more than 97% renewables.”
    Whether intentional or not, CAISO’s claim again wildly exaggerates the value of renewables to the grid it’s charged with operating.

    Here’s why:

    • to determine the percentage of renewable electricity Californians were using April 3
      requires comparing the power generated by renewables to the power of all sources added together
      – not simply to in-state demand (if some power is exported or used to charge batteries the grid mix remains unchanged).
    • At 3:40 PM, all sources combined were generating 22,782 megawatts (MW),
      while renewables were generating 18,058 MW, or 79.3% of the current grid mix.

      CAISO’s 2022 claim thus exaggerates the contribution of California’s renewables by a generous 23%.

    Some might argue that generating 79% of California’s electricity from clean sources deserves recognition.
    If correct, it would be an achievement on par with that of 1980s France, which lowered its CO2 emissions by 75%
    with a rapid buildout of nuclear power.
    California’s achievement, however, was a fluke, a mistake that lasted for a few seconds.
    In contrast, France’s nuclear plants have provided a full ¾ of the country’s electricity for decades.

    It isn’t a lack of renewable electricity that is holding California back
    – it’s that renewables provide too much electricity at the wrong times, and not enough when the time is right.

    It’s attempting to lower carbon emissions by using resources that require gas-fired electricity to back them up,
    or keep them from destroying the grid.

    It’s putting blind faith in solutions that may work for flashlights, or even electric cars, but will never be practical
    for providing the immense power needs of an electrical grid
    (enough battery capacity to power our state for one day, and the extra solar and wind infrastructure
    to charge it, would cost at least twice California’s annual budget).


    But most of all, California’s environmental policy is failing for a lack of honesty.

    The only thing remarkable about comparing last April’s grid mix to this year’s is their sameness
    – despite all of CAISO’s hyperbole, we’re making little or no progress at lowering climate emissions.

    Some have simply been exported by replacing in-state gas consumption with “unspecified imports,” a euphemism for  electricity from out-of-state gas and coal plants.

    We still need to curtail (limit) solar production between the hours of 9 AM and 3 PM to avoid overloading the grid,
    and we still need to pay our neighbors to accept our unwanted electricity at mid-day.
    Our solar farms are still generating no electricity at 8 PM, when clean electricity is needed most,
    yet we build more, and more, and more of them
    – as if making the sun shine at night was a problem that could be solved by more investment.

    It should be obvious that California can’t possibly meet its climate goals continuing on this errant path, yet we soldier on anyway.
    There’s a chance, of course, that preventing the worst effects of climate change is already impossible.

    But worse would be failing to prevent them because our leaders didn’t have the humility to admit they were wrong about how to get it done.

Carl is a lifelong environmentalist and clean-energy advocate, and credits his pro-nuclear leanings to spending his youth in a state which generates more than half of its electricity with nuclear energy.
