San Mateo commission reviews Electrify San Mateo plan, hears broad public support and cost concerns

San Mateo’s Sustainability and Infrastructure Commission on May 14 heard a staff presentation and community feedback on “Electrify San Mateo,” a city project laying out policy pathways to replace natural‑gas appliances with electric alternatives in existing buildings.

The commission received an overview from Andrea Chow, the city’s sustainability analyst, and Ryan Gardner of Rincon Consulting on five policy pathways — business as usual (new construction reach codes and voluntary adoption), renovation reach codes (for example, replacing central air with reversible heat‑pump systems), a faster local ban on gas space and water heating (a 0 NOx path), commercial building performance standards, and a municipal “electric‑first” policy for city facilities.

Gardner framed the work as part of the city’s climate goals and said electrification focuses on “replacing natural gas‑fired equipment with electric equipment,” noting efficiency advantages: “What is really cool about heat pumps is they’re about 400% efficient.” He added that local modeling from regional providers shows household bill savings after electrification, saying, “the average household is gonna save about $20 a month when they switch to a heat pump water heater and about $20 a month when they switch to a heat pump HVAC.”

Why it matters

The plan aims to reduce greenhouse gases and indoor air pollutants that public‑health researchers link to childhood asthma and other conditions. Staff and the consultant emphasized that policy design must balance near‑term costs, possible electric‑service upgrades, and equity considerations so savings over time are not outweighed by unaffordable up‑front costs for renters or homeowners.
