The report concludes that diesel generators in the South Coast and Bay Area communities alone have 12.2 GW of generation capacity and produce roughly 20 metric tons (MT) of fine particulate matter, 62 MT of VOCs and almost 1,000 MT of haze-inducing NOx annually. Of these, 20,907 are diesel-fueled.ĭiesel generators release greenhouse gases, particulate matter (PM), volatile organic compounds (VOCs), nitrous oxides (NOx) and sulfur dioxide (SO2), harmful pollutants that create smog and exacerbate respiratory conditions.
In 2021, the two districts were collectively home to 23,507 backup generators with a capacity of 12.2 gigawatts (GW), about 15 percent of California’s entire electricity grid. Over the last year, the generator population jumped by 22 percent in the South Coast Air Quality Management District (SCAQMD), and by 34 percent in the Bay Area Air Quality Management District (BAAQMD) over the last three years. SAN JOSE, Calif.-( BUSINESS WIRE)- New research by economic and public policy consulting group M.Cubed finds a proliferation of backup generators across California, with nearly 90 percent being diesel-fueled, posing significant obstacles to achieving greenhouse gas reduction targets and driving nearly $136 million in annual health costs.
