Lead Performer: National Renewable Energy Laboratory – Golden, CO
Partner: SPAN – San Francisco, CA
DOE Total Funding: $710,000
Cost Share: $140,000
Project Term: October 1, 2021 – September 30, 2023
Funding Type: CRADA
Project Objective
The objectives of this project are to improve the home’s utility bill savings (under time-of-use, real-time pricing, or demand charge rate plans), reduce carbon emissions, and extend the resilience operation period by at least 10%. NREL will collaborate with SPAN to develop, validate, and demonstrate a smart electrical panel-based home energy management system (HEMS) to reduce energy costs, provide resilient operations during extreme weather events, and reduce emissions. The team will integrate NREL’s HEMS in the SPAN smart electrical panel to leverage the high-frequency, circuit-level power measurements and perform multi-objective optimization-based control of the household loads and behind-the-meter distributed energy resources. In this project, the team will develop new capabilities to enable high-value applications such as utility bill reduction, decarbonization, enhanced resilience, auto-calibration and self-learning, and circuit-level miscellaneous electric loads monitoring and analytics. In 2023, the team will develop a prototype of the HEMS-integrated smart panel, perform laboratory validation and field demonstration, and explore commercialization pathways. The proposed technology will start at technology readiness level (TRL) 5 and reach TRL 7 by the end of the project; SPAN will continue the system development and plan to launch the product in 2024.
Project Impact
The expected outcome of the project is a field-proven, production-ready, smart electrical panel-based HEMS that helps homeowners save on utility bills, reduce carbon emissions, enhance resilience, and detect anomalies in building equipment.
