CalMTA’s Room Heat Pumps (RHP) Market Transformation Initiative (MTI) aims to accelerate market adoption of room heat pumps to provide efficient heating and cooling in existing small, single-family, and multifamily households.
With a forecasted Total System Benefit (TSB) of $521 million, RHPs offer a significant, cost-effective opportunity to reduce energy demand and associated infrastructure costs, which are a primary driver of electric rates in California. Over time, the initiative will transform the market and lock in energy savings, grid benefits, and greenhouse gas (GHG) reductions to help meet California’s climate goals.
The Room Heat Pumps MTI Plan is based on 18 months of development, research, outreach, and analysis. It was submitted to the California Public Energy Commission (CPUC) via an Application on December 20, 2024.
This appendix includes the baseline assumptions and a thorough assessment of the market state, supply chain, market actors, and other programs that support the MTI.
This Advancement Plan summarizes available information and essential research activities for the proposed Market Transformation Initiative (MTI) that CalMTA recommends advancing from Phase I: Concept Development into Phase II: Program Development.

CalMTA’s Phase II research for the Room Heat Pumps Market Transformation Initiative (MTI) identified the need for research to better understand how consumers install, interact with, and utilize this technology. The Room Heat Pumps Self-Installation Practices Strategy Pilot was developed to yield greater insight into two primary assumed benefits of
The 2024 Annual Report highlights CalMTA’s key activities and achievements in developing a market transformation (MT) portfolio and advancing California’s energy efficiency and decarbonization goals. Notable highlights in 2024 include:
CalMTA made substantial progress on several operational and market transformation initiative (MTI) development milestones in the 1st quarter of 2025. The CalMTA team shared activities related to market transformation idea development, stakeholder outreach, operational aspects, and financial status. This included reports on two Strategy Pilots for Induction Cooking and Room
CalMTA’s Phase II research for the Induction Cooking market transformation initiative (MTI) identified key barriers to adoption, including low consumer awareness of induction technology and its benefits, cultural and consumer attachment to gas cooking, and concerns about the durability of newer induction products. To address these challenges, CalMTA sought to test interventions
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.
