PSE&G Installs and Commissions 1 MWh Eos Aurora Battery System for Solar 4 All® Microgrid Project at New Jersey Water Treatment Facility
Advanced Solar Products, Eos, and Siemens Team Up to Deliver Solar-Plus-Storage Microgrid to Enhance Storm Resiliency While Providing Value-Added Grid Services
WEST CALDWELL, NEW JERSEY, October 25, 2017 - Eos Energy Storage announced the installation and commissioning of a 250 kW | 1 MWh Eos Aurora® DC battery system at the wastewater treatment plant in the Borough of Caldwell, NJ. The batteries are a central component of Public Service Electric and Gas Company's (PSE&G's) on-site solar-plus-storage microgrid that will help keep the facility operating during extended power outages. The Caldwell microgrid is part of the New Jersey utility's Solar 4 All® program.
The microgrid includes an Eos Energy Storage system and an 896 kW-DC solar PV system designed and installed by Advanced Solar Products of Flemington, NJ. Siemens Energy Management integrated the Eos Aurora system, solar facility, and existing diesel generator, using the Eos Znyth® battery technology as the backbone of the microgrid to reinforce emergency resiliency for this piece of critical municipal infrastructure. Siemens also provided the intelligent control technology to monitor, manage and distribute power across the system.
The solar and battery storage systems are connected directly to PSE&G's electric grid. Under normal conditions, the solar panels deliver power to the grid and the battery storage system can provide value-added grid services for integrating solar onto the grid and participating in ancillary markets.
The Caldwell wastewater treatment plant microgrid is part of a 3 MW-DC portion of the Solar 4 All program. The initiative develops projects that integrate solar with other technologies to reduce the impact of solar on the grid or to demonstrate reliability and grid resiliency of solar for critical facilities during prolonged power outages. The solar installation, combined with Eos' long-duration energy storage, significantly extends backup power capacity and emergency operation of critical water treatment capabilities.
"One of the goals of our Solar 4 All program is to help support the growth and development of solar and related industries in New Jersey," said Todd Hranicka, director - solar energy at PSE&G. "So we were especially happy to include the battery technology from a fellow New Jersey company like Eos into a project that helps make our electric system and a piece of critical infrastructure more reliable and resilient."
Construction of the solar-plus-storage system at the Caldwell wastewater treatment plant was a joint effort between Advanced Solar Products, Eos, and Siemens Energy Management. The Eos Aurora battery system was selected on the basis of its multi-hour duration and the benefits of its simple, sustainable and inherently stable zinc hybrid cathode design.
"Increasingly, we are deploying batteries as an add-on to solar not only because they provide critical power reliability when needed but also because they can generate revenues when the grid is up and running," said Lyle Rawlings, CEO at Advanced Solar Products.
The integrated product solution combines Siemens' AC power conversion and intelligent controls with Eos' modular Energy Stack™ design to enable quick deployment and ease of maintenance. The project is backed by Siemens' installation support and warranty services.
"This project is a leading example of the role technology can and should play in making our regions more resilient," said Dan Wishnick, Principal Business Developer, Siemens Medium Voltage Systems. "We value our work with this project not only as the integrator, but also in providing the intelligent control technologies that help monitor, manage and deliver the power necessary to run this facility rain or shine."
"The Caldwell project is truly a landmark for us," said Michael Oster, CEO at Eos. "It shows that municipalities and utilities are embracing large-scale, long-duration energy storage in a manner that will greatly enhance public safety and grid resiliency. We are proud to partner with these industry leaders and look forward to setting new standards for energy reliability and cost effectiveness."
Eos is headquartered in Edison, NJ and was recently awarded a $2M loan through the Edison Innovative Green Growth Fund (EIGGF) to advance its energy storage technology in the Garden State. Eos is expanding operations in New Jersey and expects to create 71 new jobs in the state within the next five years.
