ZNE Tract Home Retrofit

The purpose of this project is to demonstrate zero-net-energy (ZNE) or near ZNE by retrofitting several homes by applying energy efficiency measures, demand response enabling technologies, and renewable generation source. This is a field demonstration project consisting of simulation, identifying and installing EE measures, M&V, recalibration of simulation models, and recommendations.

With a vision of safely providing a more reliable and affordable electric system, Southern California Edison Company (SCE) was awarded up to $39.6 million in matching funds from the U.S. Department of Energy (DOE) to conduct the Irvine Smart Grid Demonstration (ISGD). This demonstration tested the interoperability and effectiveness of key elements of a modernized electric grid—from the transmission level through the distribution system and into the customer premises. This end-to-end demonstration of smart grid technologies is helping SCE address several profound changes impacting the electric grid’s operation, including increased use of renewable resources, more intermittent generation connecting to the distribution system, the ability of customers to actively manage the way they use electricity, and policies and mandates focused on improving the environment and promoting energy security.
