CalMTA hosted a Residential Heat Pump Water Heating (HPWH) Market Acceleration Summit from Aug. 26-27 in Oakland, California. This invitation-only event brought 40 leaders, innovators, and decision-makers together to help define the pathways that will make heat pump water heaters (HPWHs) the preferred choice for California homes.
HPWHs are a high-value technology that are critical to helping California meet its energy efficiency and decarbonization goals. While many important programs are already working to increase installations across the state, market share for key HPWH products remains relatively low.
CalMTA is investigating a potential initiative that aims to support current efficiency interests focused on residential HPWHs to accelerate market adoption to achieve statewide goals. This summit helped define which actions or interventions CalMTA could pursue to fill the gaps and accelerate market adoption of HPWHs.

CalMTA is a market transformation program of the California Public Utilities Commission (CPUC) and is administered by Resource Innovations. The program uses market-level strategies to break down barriers and accelerate adoption of identified energy efficiency and GHG reducing technologies and practices.

The California Market Transformation Administrator (CalMTA) develops and manages market transformation initiatives in the state to reduce energy use and reduce greenhouse gas (GHG) emissions.


CalMTA follows a rigorous process for reviewing, scoring, and then developing relevant, timely market transformation initiatives. The process supports market transformation initiative creation from concept to program development to market deployment, as well as the eventual exiting of the market.
