US energy storage solutions provider Eos Energy Storage has announced forward pricing for its Eos Aurora DC Battery System and has started taking orders with what it said are costs at 30% below those of the existing storage system in the market.
Eos offers volume purchases at a price of $160/kWh for shipment in 2017 and $95/kWh for shipment in 2022.
The firm said it is the first to accept orders below $100/kWh for a complete DC battery system, including battery modules, battery management system, and outdoor-rated enclosure, with up to 20-year performance guarantees at additional cost to optimise capacity.
Using its patented Zynth (zinc hybrid cathode) technology, the Eos Aurora battery system can reach 5,000 full depth-of-discharge cycles, the company said.
The system comes in 250kW/1MWh, but its scalability is only limited to the project’s available footprint, Eos said.
Michael Oster, Eos CEO, said: “From the bill of materials to the manufacturing process and simplified installation strategy, Eos is taking a fundamentally different approach – one that gives us a significant and sustainable cost advantage over lithium-ion while delivering a battery that is inherently safer, with a longer life, lower maintenance, and more tolerant of extreme operating conditions.”
Meanwhile, Eos and Northern Power Systems (NPS) have announced they will work together to install a 1MW/4MWh grid-scale energy storage solution for a hybrid solar and wind demonstration project, developed by French natural gas distributor ENGIE.
The fully-integrated battery storage system will be co-located with more than 5MW of wind and solar generation capacities at a medium voltage substation in Tubarão, Brazil.
The project represents ENGIE’s first large-scale deployment of an Eos Aurora system in South America and follows extensive prototype testing at ENGIE’s Batteries Lab in Linkebeek, Belgium.
Eos and NPS will partner up to manufacture and supply the energy storage system combining the Eos Aurora battery with Northern Power’s FlexPhase power conversion technology and intelligent controls.
Northern Power’s engineering design team will be leading the field installation of the energy storage system with construction starting in the summer of 2017.
Last month, BBB also reported another partnership between Eos and a major integrator.
Eos is working alongside Siemens Corporation, a subsidiary of German firm Siemens AG. Eos and Siemens have jointly developed energy storage systems that include AC power conversion and controls to enable cheaper system upgrades.
