Room Heat Pumps MTI Plan
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. Below are links to the full plan as well as the supporting appendices.
- Appendix A: Logic Model
This appendix includes the MTI’s full Logic Model. The Logic Model is a systematic and visual way of presenting CalMTA’s understanding of the interventions necessary to remove barriers, expected outcomes of those interventions, and a pathway to the desired end state. - Appendix B: Market Forecasting and Cost-Effectiveness Modeling Approach
This appendix details the inputs, sources and methods used to develop the market forecasting, Total System Benefit (TSB), and cost-effectiveness model for this MTI. - Appendix C: Product Assessment Report
This appendix presents the findings on the technology research conducted in Phase II and on behalf of the MTI. - Appendix D: Market Characterization Report
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. - Appendix E: External Program Alignment & Coordination
This appendix describes how CalMTA will communicate and collaborate with key market actors and program stakeholders. - Appendix F: Evaluation Plan
This appendix describes the plan to track the progress and assess the impact of the MTI over time. - Appendix G: Risk Management Plan
This appendix documents the potential risks and obstacles to the MTI and CalMTA plans to mitigate the risks. - Appendix H: Phase III Cost Estimate
This appendix details the budget requirements for the MTI. - Appendix I: MTAB Feedback
This appendix contains feedback on the MTI Plan from the Market Transformation Advisory Board.
