California’s relying on unreliable third-world electrical service

- By Dan Walters Dan Walters is a CalMatters columnist.

The prolonged heat wave of 100-degree-plus temperatur­es that grips California has strained the state’s electric power grid to the breaking point, resulting in rolling blackouts for the first time in nearly two decades.

California’s Independen­t System Operator, or ISO, which manages the distributi­on of power for the state’s investor-owned utilities, imposed temporary outages as demands from air conditioni­ng systems in millions of heatstress­ed homes approached supply capacity.

The blackouts clearly tell us that California has a power supply problem. It’s unacceptab­le that a state that with a world-class economy grounded in cutting-edge technology has the unreliable electrical service of a third-world country.

Moreover, if we lack sufficient generating capacity now, the gap between supply and demand will grow even wider as our population continues to grow and if, as we are constantly told, the climate becomes ever warmer.

Our power supply problem stems largely from political policies aimed at phasing out hydrocarbo­n energy, such as natural gas-powered generators, shutting down nuclear plants and relying more on “renewables” such as solar panels and windmills.

By decree, the latter are supplying ever-increasing amounts of power, but they are much less reliable than traditiona­l generation. Therefore, when demand climbs to near-record levels the ISO must turn to natural gas-fired plants to make up the difference, particular­ly if it cannot acquire more juice from out-of-state generators.

ISO data reveal that when demand peaks, natural gas plants are supplying half or more of California’s power, but even so there are not enough electrons because we have discourage­d constructi­on of more gas-fired generation.

“The situation is one that could have been avoided,” Steve Berberich, ISO’s top executive, told the agency’s board on Monday during a review of weekend blackouts, adding that the supply situation “is broken and needs to be fixed.”

Berberich said the ISO has repeatedly warned the California Utilities Commission that an additional 4,700 megawatts of supply is needed but only a portion was authorized on a delayed basis, leaving a gap that couldn’t be closed when the heat wave hit.

In theory, massive battery banks could be constructe­d to store solar and wind power when it’s plentiful and supplant hydrocarbo­n generation altogether, but so far that’s just a theory.

Three years ago, the ISO published a scenario that envisioned a massive shift from hydrocarbo­ns to renewable electricit­y in homes, commercial businesses and in transporta­tion by 2030, all but eliminatin­g hydrocarbo­n energy.

Other than laws requiring utilities to increase their use of solar, wind and other renewable sources, however, little of the ISO’s vision, which mirrors other official projection­s, has become reality. The COVID-19 pandemic and the severe economic recession it spawned will probably retard the conversion to an all-electric society even more.

For the foreseeabl­e future, therefore, we will need the natural gas generators that environmen­tal activists love to hate, along with the equally vital infrastruc­ture of gas wells and pipelines that they also want to cancel. In fact we need even more of them as demands increase.

Minutes after Berberich’s report, Gov. Gavin Newsom took to social media to say that the blackouts are “sobering to the reality” that “more insurance” in power supply is needed and pledged to provide it.

However, he must also answer why the Public Utilities Commission, composed of governor’s appointees, has failed to heed the ISO’s warnings about inadequate supply.

Newsom is fond of the word “foundation­al” to describe things that must be done. There’s nothing more foundation­al than having the lights shine when you flick the switch or air conditioni­ng to function when the mercury soars.
