Moderator: Carol Yin, Facilitator, ETCC
In 2022, ETCC members identified three key areas of market transformation that would be important for reaching California’s decarbonization goals: distributed energy resources, low global warming potential refrigerants, and commercial water heating. We start off our Summit by bringing together these driving forces to discuss their organizations' approach to market transformation and to give an update on the status of these markets with regards to objectives.

Moderator: Martin Vu, Principal, RMS Energy Consulting, LLC
This session will delve into groundbreaking innovations and demonstrations that are driving the transformation of water heating systems towards a low-carbon future. Join us as leading experts and organizations present their pioneering projects and technology evaluations aimed at decarbonizing water heating in various settings.
Gas Absorption Heat Pump Water Heaters
Speaker: Cristalle Mauleon, Engineering Manager, Lincus Inc. (CA Gas ET) | Slides
Gas Absorption Heat Pumps (GAHP) have been around for many years, but applying them to the domestic hot water heating end use is a novel application that the California Gas Emerging Technologies program is evaluating. This presentation will give an overview of the GAHP technology, how GAHPs can improve the coefficient of performance of a system, and how they can support decarbonization and low global warming potential goals and mandates.
Large Capacity CO2 Central Heat Pump Water Heating
Speaker: Nick Young, Director, Zero Carbon Buildings, Association for Energy Affordability | Slides
Through an EPIC Grant, AEA is leading a team to design and install large capacity CO2 central heat pump water heating systems at five existing low-income housing sites in disadvantaged communities across the state of California. All sites include significant pre- and post-retrofit data collection. Through this work, we are learning many important lessons the hard way, and look forward to sharing them with attendees to help advance these low-carbon water heating systems that are so crucial to decarbonizing multifamily housing.
Central CO2 Heat Pump Water Heater Performance and Load Shifting in Multifamily Buildings
Speaker: M M Valmiki, Senior Engineer, ASK Energy (CalNEXT) | Slides
This study evaluates central CO2 heat pump water heating systems installed at two existing low-income multifamily buildings in San Francisco, enhanced with load shifting controls. Central heat pump water heating is a key element to electrification efforts in California (and elsewhere) and accompanying load shifting features are a necessary emerging technology that demands further study and development. Hot water demand, total system performance, and load shifting abilities will be assessed through comprehensive measurement and verification.
This session will explore the efforts of utility programs to harness the power of distributed energy resources (DERs) in order to get useful demand flexibility that will bolster grid reliability and resiliency in California. Join us as our speakers present pioneering projects and innovative solutions that can shape a more secure and sustainable energy future.
Moderator: Rafael Friedmann, Facilitator, ETCC
Investigating the Potential for Residential PV Systems Paired With a Home Battery System to Support California's Grid Reliability
Speakers: Albert Chiu, Product Manager, Pacific Gas & Electric and Stephanie Bieler, Principal, Demand Side Analytics | Slides
Between 2017 and 2022, the installed nameplate capacity for residential battery storage grew from less than 50 MW to over 300 MW. As it grows, a key question is whether and how well those resources can be used as a grid resource based on TOU, DR and RTP signals. In 2021-2022, PG&E implemented a pilot to investigate how residential battery storage systems could be leveraged as a resource when the grid is experiencing stress and dynamic rate optimization. The presentation will focus on how customers are using battery storage on their own and how that impacts the grid.
SDG&E's Virtual Power Plant Project
Speaker: Jeff Barnes, Emerging Technologies Project Manager, San Diego Gas and Electric | Slides
SDG&E’s Virtual Power Plant project is evaluating the control, dispatch, and real-time signaling of behind-the-meter resources installed throughout a vulnerable community in the SDG&E service territory. This project is particularly unique because of its use of multiple end use devices and different technology providers, including thermostats, well water controllers, water heater controllers and battery storage. SDG&E will provide an overview of the project and provide preliminary findings based on signaled events to date.
SCE Flick Power Study: Using Pre-Attentive Color Schemes to Enhance Responsiveness to Time-of-Use Electric Rates
Speakers: Mark Martinez, Senior Portfolio Manager, Demand Response Emerging Markets and Technologies, Southern California Edison and Andre Ramirez, CEO, Flick Power | Slides
The concept of Pre-Attentive Notification (PAN) is defined as the process of providing subconscious information without an observer directly noticing it. The color from the Flick system is pre-attentively processed and that differs from direct stimulus and can be more effective in changing sub-conscience behavior. PAN is naturally occurring all around us (visual clues, sounds, olfactory, etc.) but is typically found in advertising, education, and media marketing as a subtle influence. Learn how the color-changing PAN signals for this project signify time-based electric rate signals directly from SCE to give occupants in the home or building the “nudge” they need to make informed decisions about energy use and to respond to the TOU price signals.
This session will highlight cutting-edge presentations about issues and drivers shaping the future of refrigerants. Join us for an exploration of sustainable heat pump technology, the impact of low global warming potential (low-GWP) refrigerants on the carbon credit market, and the environmental impacts of per- and poly-fluoroalkyl substances (PFASs).
Moderator: Paul Delaney, Facilitator, ETCC
A Near-Zero-GWP Heat Pump System for All-Electric Heating & Cooling in California
Speaker: Aaron Tam, Research Engineer, Electric Power Research Institute | Slides
Heat pumps in the California climate are ideal for the decarbonization of space heating end use. This presentation provides an overview of the design and demonstration of a heat pump with ammonia (NH3) acting as its primary refrigerant, and carbon dioxide (CO2) acting as a thermal distribution fluid. This system can be a near-zero-GWP option for multifamily and small commercial applications with reduced piping installations costs.
How PFAS Restrictions Could Impact Refrigerants
Speaker: Tim Whitehouse, Executive Director, Public Employees for Environmental Responsibility | Slides
This presentation provides a perspective on the latest developments in the regulation of PFAS and how these will affect the business case for synthetic and natural refrigerants.

This comprehensive program not only includes pilot projects but also incorporates a robust data gathering effort to inform critical Commission decisions. By directly addressing the energy needs of disadvantaged communities, this program will serve as a blueprint for extending affordable energy options to other identified communities in the region, promoting equitable access to sustainable energy solutions.
Challenges of Installing HPWHs: Who Do I Call?
Speaker: Ron Kliewer, Principal Building Scientist, Kliewer and Associates, LLC | Slides
Heat pump water heaters are not a simple swap-out like when you would replace a gas water heater with a similar gas-fired model. There are HVAC and Electrical component design considerations, as well as plumbing, that are crucial when installing HPWHs. Adding additional complexity are recirculation loops. Recirculation line losses can be a FAR bigger energy user than hot water use alone. Hot water is a system, and we pay a price when we forget that. Hot water systems need to be designed and built so they are easy to maintain. Unfortunately, new hot water systems are often complex and we need to be prepared for this. Training industry stakeholders is essential to HPWH performance success.
