California hosts a largely hidden and quick growing grid of dispersed diesel generator generators; those low buzzing large containers positioned at internet server farms, hospitals, police stations, and, during Outside Lands, Golden Gate Park. In 2018, roughly 6,500 back-up generators, often known as “BUGs,” were littered throughout the San Francisco Bay Area, capable of power up a collective 3,810 megawatts (MW). In 2021 – lower than three years later – BUG deployment had reached 8,722 generators, 4,840 MW of energy supply, a 34 percent leap in the again-up generator fleet.
There are enough Bay Area BUGs to light up more than two San Francisco’s, on a day when demand is at its absolute highest.
Similarly, in 2020 there have been 12,104 back-up generators totaling 2,697 MW of capability in the realm regulated by the South Coast Air Quality Management District. Only a 12 months later this inhabitants had grown to 14,785 BUGs, 7,360 MW capability, a 22 p.c increase in the swarm.
California’s electricity grid can supply about eighty gigawatts of power. BUGs within the Bay Area and South Coast alone can generate roughly 15 % of your complete grid.
Throughout the state larger generators are being deployed extra rapidly. Nearly ninety percent of back-up generators positioned within the Bay Area and South Coast are diesel fueled.
Residential generators, which are largely unregulated, and for which population information are unavailable, are equally flying off shelves, like so many cicadas waking up from a long sleep. Despite boosting manufacturing of standby residential generators with a brand new South Carolina plant, Waukesha-primarily based Generac Power Systems, the largest provider of residence-primarily based BUGs, has a six-month backlog and is considering including a West Coast manufacturing unit.
diesel generator set generators are usually positioned close to the place individuals stay, work, and attend faculty. They continuously squat in communities that’re already topic to a number of pollution sources, as measured by CalEnviroScreen, which maps pollution burdens all through the state. Ironically, given state and native climate and net zero emission goals, the public sector is amongst probably the most voracious BUG adopters. In South Coast, governments owns nearly 14 % of the inhabitants, with well being care services responsible for one more roughly 10 percent.

Within the Bay Area, the public sector accounts for thirteen % of nonresidential generators.
Legislators, protective of taxpayer monies, deploy BUGs as a low-price resolution to reliability points. But they’re a major source of greenhouse gases, particulate matter (PM), volatile natural compounds (VOCs), nitrous oxides (NOx), and sulfur dioxide, which may create smog and exacerbate respiratory conditions, like asthma, chronic obstructive pulmonary illness, and lung cancer, especially for kids and older adults.
Non-residential BUG use in the Bay Area and South Coast alone produces annual emissions of no less than 86,899 metric tons of carbon dioxide (MTCO2), roughly 20 MT of high-quality PM, sixty two MT of VOCs, and virtually 1,000 MT of haze-inducing NOx. This pollution, in turn, might set off upwards of $136 million of well being costs a 12 months, attributable to increases in mortalities, heart assaults, hospital visits and other opposed penalties. Costs related to the statewide fleet of BUGs, as well as residential generators, are much greater.
Data associated to the number of hours that diesel generators function is self-reported, with little regulatory scrutiny. The diploma to which BUGs run is influenced by a number of factors, together with wildfires, Public Safety Power Shut-offs, extreme weather, and potentially their use to arbitrage more and more costly electricity costs.
In California, non-residential BUGs are individually permitted by one of 35 air districts wherein they’re situated. Their cumulative magnitude is largely hidden; data from the districts shouldn’t be meaningfully aggregated or reported at the state degree.
Absent new policy directions, the position diesel technology performs in California’s vitality combine will continue to extend. Looking for low-value and expediate methods to make sure reliability within the face of potential provide shortfalls, Governor Gavin Newsom and regulators have greenlit just about unrestricted use of diesel generators in the close to future.
