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.
