In Richmond, California, Zenaida Gomez is ready to say goodbye to the gas stove in the apartment she has rented for over a decade. She has a hunch that the pollution it emits is exacerbating her 10-year-old son’s asthma attacks, and she has heard from public health experts and doctors who’ve said it probably is.
“I’ve learned that not only do we have contaminated air when we are outside in Richmond, but there’s contamination and toxins within our homes,” Gomez said in a recent phone call.
She started attending City Council meetings and organizing with her neighbors as a member of the Alliance of Californians for Community Empowerment (ACCE) Action, because, she said, “I wanted something different. I wanted something better.”
But ACCE Action’s goal isn’t simply to get rid of gas stoves. In a city where about one in four people — nearly double the national average — suffer from asthma due in large part to pollution from heavy industry, the group wants to shut off or “prune” the lines that send natural gas into homes in some neighborhoods. The phenomenon is called “neighborhood-scale decarbonization,” and it’s just getting off the ground in California.
Pacific Gas & Electric, the utility in the area, is on board with the idea. It has expressed a willingness to spend a portion of the money it would otherwise use to maintain gas lines to help electrify the homes in the neighborhood that will no longer use the gas.
David Sharples, county director at ACCE Action, says the group is looking at different neighborhoods that PG&E has identified as likely candidates. Once the group chooses an area, it plans to run a pilot project with the goal of electrifying all the appliances and adding solar panels and batteries for up to 80 homes.
“We’re looking at the Coronado, Iron Triangle, and Santa Fe neighborhoods, which are working-class, Black and brown neighborhoods where ACCE has been organizing for years,” Sharples said. “They all have old gas lines that need to be replaced, so it represents an opportunity to electrify.”
To understand the appeal of neighborhood-scale decarbonization, which is also sometimes called “zonal decarbonization,” it helps to be able to envision the vast network of gas pipelines that exist under most cities in the Western U.S. That network holds a potentially explosive gas, and it requires constant, expensive upkeep.
Experts say a large-scale effort just makes more sense than a piecemeal approach in many parts of the state. And as dramatic as it might sound to transition a whole block or neighborhood off gas at once, the approach may also cost less overall and make it easier to employ people fairly.
Neighborhood-scale decarbonization has also been popular with lawmakers. Last fall, the California Legislature voted to adopt SB 1221, a bill that will enable up to 30 neighborhood-scale projects of this type over the next five years.
The catch is that most residents in the neighborhoods must agree to the change. While the state’s obligation to serve currently requires 100% approval, SB 1221 will lower the threshold to 67% as the pilot projects start rolling out. Several groups have begun the work of educating communities about the benefits of the switch.
In Albany, a city of about 20,000 people north of Berkeley, Michelle Plouse, the city’s community development analyst, has spent the last few years working with PG&E to pilot one of the first neighborhood-scale projects in the state. Using the gas line mapping tool developed by the utility, Plouse and other city staff worked with the Albany City Council to identify 12 potential blocks. This spring, they narrowed it down to three.
The goal, Plouse said, is to find blocks that are easier to electrify while also focusing on lower-income parts of the city, where residents are less likely to be able to afford to electrify.
