CalMTA’s Commercial Rooftop Units (CRTUs) Market Transformation Initiative (MTI) aims to accelerate market adoption of high-performance heat pump RTUs with advanced features as an efficient heating and cooling solution for California’s commercial buildings.
CRTUs offer a significant, cost-effective opportunity to reduce commercial building energy consumption, increase HVAC system resilience, reduce peak demand, and unlock grid-supportive flexibility at scale. Over time, the initiative intends to transform the market and lock in energy savings, grid benefits, and greenhouse gas (GHG) reductions to help meet California’s efficiency and decarbonization goals.
This MTI Plan is based on more than two years of development, research, outreach, and analysis. Links to the supporting appendices are listed to the right. Additional appendices and the full plan will be available soon. CalMTA will submit this the full plan and appendices to the California Public Utilities Commission (CPUC) via an Application in 2026 following MTAB review in November.

The Heat Pump Water Heating Collaboration Webinar brought together stakeholders to learn more about the proposed Market Transformation Initiative and our collaborative approach to its development. Attendees had the opportunity to ask questions, share feedback, and engage in discussion directly with the MTI development team, helping to foster transparency, alignment,
Market transformation initiatives (MTIs) typically begin with market research to validate or identify strategic interventions needed to remove market-level barriers and leverage opportunities to accelerate adoption of a technology, practice or service. Once an MTI moves into the market deployment stage, those interventions must be translated into specific strategies, tactics
The Residential Heat Pump Water Heating (HPWH) MTI seeks to accelerate market adoption of HPWHs in California’s residential markets. HPWHs are a proven, high-efficiency technology and are a key solution for achieving the state’s building decarbonization, grid reliability, climate, and installation goals of 6 million heat pumps by 2030.
The CRTUs MTI seeks to accelerate adoption of advanced heat pump RTUs with innovative features that optimize efficiency and performance but are not currently widely available – unlocking new pathways to cost-effectivedecarbonization in the commercial sector.
CalMTA’s Residential Heat Pump Water Heating (HPWH) Market Transformation Initiative (MTI) aims to accelerate market adoption of heat pump water heaters in the single-family and small multifamily property sectors. HPWHs offer a substantial grid and energy efficiency benefit to California’s housing stock and are a foundational technology for achieving the
This Market Characterization Report is an output of the Phase II research for the Residential Heat Pump Water Heating (HPWH) Market Transformation Advancement Plan, finalized in September 2024. The plan outlined a high-level research approach that focused on investigating the target market, barriers, and opportunities with the goal of supporting
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.
