What it is

California aims to install 6 million heat pumps by 2030 as part of building decarbonization strategy, but a Harvard study finds the state’s highest-in-nation residential electricity prices make heat pumps economically unattractive compared to gas in many areas. The study analyzed utility bills, usage, and winter temps across U.S. counties to map where heat pumps save or cost money.

Why it matters

Facilities managers and building owners evaluating electrification retrofits face a tension between policy mandates and operating cost increases. When electricity rates are high relative to gas, heat pump conversions may raise tenant or occupant utility bills, undermining adoption despite streamlined permitting and incentives. This rate-vs-fuel-cost dynamic directly affects project feasibility and payback calculations for multifamily and commercial retrofits.

Evidence from source:

  • California aims to install 6 million heat pumps in homes by 2030
  • Harvard study analyzed residential energy costs, usage, and winter temperatures in every U.S. county to determine where heat pumps increase vs. decrease utility bills
  • Lawmakers proposing to streamline permitting and make it easier to electrify homes this year

Open questions

  • What electric rate structures or demand charges make heat pumps pencil in California commercial/MDU contexts?
  • Are there upcoming CA rate reforms or grid modernization efforts that would improve heat pump economics?
