New Jersey energy utility PSE&G has installed a 250kW/1MWh Eos Aurora battery system, using zinc hybrid cathode technology, for a solar microgrid project.
The zinc hybrid battery system, developed by US firm Eos Energy Storage, has been deployed at a wastewater treatment plant— to act as “a central component” of PSE&G’s on-site solar-plus-storage microgrid to keep the facility running during extended power outages.
Eos and German company Siemens jointly built the system, which is connected directly to PSE&G’s electric grid.
PSE&G said Siemens Energy Management integrated the Eos Aurora system, solar facility, and existing diesel generator, using Eos’ zinc battery technology as the “backbone” of the microgrid to reinforce emergency resiliency for the infrastructure.
The Caldwell microgrid is part of a 3MW-DC portion of the PSE&G Solar 4 All programme, which is developing 158MW of solar capacity to generate enough energy to power about 25,000 New Jersey homes.
