The system will be deployed and tested at the new GDF Suez Batteries Lab at Laborelec, in Linkebeek, Belgium.
The lab intends to develop the capability to estimate the evolutions of battery technologies in terms of cost and performance.
The performance of the Eos system will be estimated over a range of applications like facility energy management, integration of distributed solar photovoltaics, participation in grid balancing markets and energy arbitrage in wholesale markets.
Aurora, the Eos’s grid storage product, is a containerized MW-scale DC battery system designed to improve the integration of renewable energy into the grid in terms of reliability, efficiency and resiliency while reducing costs and electricity bills.
The company intends to divest the Aurora DC battery system for $160 per kWh, and will work with several parties to sell, install, and service AC-integrated battery systems.
GDF Suez research & technologies director, executive committee member Raphaël Schoentgen said: "We are looking forward to testing Eos’s Aurora system — which shows promise of being amongst the lowest cost energy storage solutions on the market.
"Rigorous testing and evaluation of Eos’s technology will allow us to characterize performance and focus on best-fit applications of highest profitability in European retail and wholesale energy markets."
Eos said the sale of Znyth battery system is part of its demonstration program, following third-party testing with DNV GL, and sets the stage for commercial deployment in several European markets.
