Project Result
Eos completed the installation, commissioning, testing, and data collection at UCSD for the C&I system in June 2020. Eos is nearing completion of testing the residential system at its facility in New Jersey. Eos will finish the data analysis and complete the final report in early 2021.
The Issue
Residential, and commercial and industrial (C&I) customer electricity rates are increasing. Also, outages as a result of natural disasters or to prevent wildfire ignition are increasing. Currently available energy storage technologies for these markets are not economical because of their high cost and short life. Also, safety and energy density limitations have prevented wide-spread deployment of energy storage on a distributed basis or at the point of consumption. Additionally, with new requirements for residential solar, the market is expecting a corresponding increase in the desire for safe and effective residential storage.
Project Innovation
This project is developing and testing behind-the-meter residential and C&I battery storage applications, on both a stand-alone basis and modeled with solar PV. This project is utilizing several kW-scale, AC-integrated Znyth battery technology storage systems. The project team is developing, modeling, and testing experimental rate designs and evaluating the impact on customer load profiles; developing control algorithms and demonstrating aggregation of multiple storage units to create virtual power plants that maximize the value of behind-the-meter storage to the utilities; and modeling, simulating, and extrapolating the economic impacts of installed systems and quantifying the benefits to California utilities and ratepayers.
Project Benefits
This project aims to validate the safety, reliability, and performance of a new aqueous, zinc-based battery technology to support customer adoption in behind-the-meter energy storage markets and applications. Behind-the-meter application of energy storage has been identified as a major commercial market for energy storage, which requires detailed field performance data to open up this market for new and emerging energy storage technologies.
Affordability
This project will help lower energy costs for residential and C&I customers by providing behind-the-meter energy storage options that may help offset peak use rates and lower demand charge costs.
Environmental Sustainability
Expanding the use of behind-the-meter storage in the residential and C&I markets will reduce overall loads in conjunction with increasing solar PV, which will reduce greenhouse gas emissions, NOx, and SO2 from existing fossil fuel generators.
Safety
Eos is the only company offering a battery technology that is inherently safer than competing technologies. This technology is non-flammable and non-toxic. In addition to being backed by UL- and ISO-certified quality assurance and control, the manufacturing process involves no toxic or hazardous materials.
