The system will be leased to Energy Storage Holdings, for a project which will evaluate energy storage technology for large-scale frequency regulation projects.
The Altair system is slated to be installed later this year.
Altairnano president and chief executive officer Terry Copeland said the company designed battery cells have greater fast charge and discharge capabilities.
Copeland said "Based upon our commercial experience in these markets, and the outstanding results of the ALTI-ESS, we are confident in raising the bar to this new level of performance."
The ALTI-ESS demonstrates excellent reliability and uptime and the battery performance has a expected life of more than 20 years.
