120V HPWH products are completing lab (UL) testing at this time and are expected to be available for field testing in Q1 2021. A field study of 8 units in SCE service area using 120V products will enhance the understanding of how the products perform and how they can be deployed. This field study...

The project will consist of an assessment of energy and non-energy impacts of moderate-low GWP refrigeration design on three newly constructed supermarkets. Each of the supermarkets will be newly opened and operating as of August 2020 with low-GWP (less than 150) and moderate-GWP systems (less than...

The project will consist of an assessment of energy and non-energy impacts of low-GWP retrofits on three supermarkets. Each of the three supermarkets are scheduled to upgrade their existing systems, replacing traditional HFC refrigerants with low-GWP (less than 150)  and reduced charge moderate-GWP...

The proposed project is an extension of an existing SCE EP project being implemented that is designed to enhance grid reliability, replace high GWP refrigerants with ammonia and/or carbon dioxide, improve efficiency, process optimization, and achieve decarbonization goals at a large bakery site....

The purpose of this project was to evaluate the impact of heat conduction losses through attic ductwork on the energy performance of variable capacity heat pumps (VCHP). Four duct scenarios were evaluated:Ducts in conditioned spaceAttic ductwork with surface area and insulation typical of...

This project evaluates the performance of a production prototype residential three-function heat pump (TFHP) system. TFHPs are called “three function” systems as they utilize a single compressor to serve indoor heating, indoor cooling, and domestic hot water loads. The system evaluated in this...

The California Air Resources Board and Southern California Edison recognized the need for robust primary research among key decision-makers to help California achieve the state’s ambitious climate goals – specifically through the adoption of zero-emission appliances such as heat pump water heaters,...

This Demand Response Emerging Technology (DRET) Voice Automation demonstration project (pilot) leveraged residential voice-assistant technology (i.e., Amazon’s Alexa smart speaker) as well as cellular telephone app functionality to engage with and educate residential customers on energy usage, bill...

The 2022 C&S Planning and Coordination Key Initiatives Report presents the activities and achievements of the P&C subprogram in the program’s five elements: Decarbonization, Grid Harmonization, Code Harmonization, Strategic Planning and Coordination, and Program Coordination. For the...

Residential heat pump space conditioning and water heating can greatly reduce energy consumption compared to typical natural gas combustion or electric resistance equipment. Multi-function heat pumps are a product type that uses one efficient outdoor compressor and heat exchanger unit to provide...
