Reno, Nev.-based Altair Nanotechnologies Inc., a manufacturer of high-performance lithium-titanate battery and energy storage products, has announced the successful completion of a demonstration and validation program for a 2 MW 500 kWh battery system purchased by AES Corp.
The program was developed and validated by consulting firm KEMA Inc. and executed by AES personnel and subcontractors. KEMA's testing showed the battery system successfully met the milestones for the program, which was conducted to demonstrate the applicability of Altair's large-platform technology to frequency regulation, a key service currently provided by power plants to the electric grid. Altair says this demonstration suggests that the technology could be used for several other utility applications.
‘Fast-responding, high-efficiency energy storage systems such as these will create a more resilient grid and allow for increased use of variable generating sources such as wind and solar,’ says Chris Shelton, director of energy storage development at AES.
The 2 MW battery system was installed and operated at a substation owned by Indianapolis Power & Light (IPL), an AES company. The system contained two 1 MW battery storage units, each consisting of one Altairnano 250 kWh lithium titanate battery stack, AC-to-DC power conversion system, high-voltage alternating current units, a control system and transformers to connect to the IPL grid.
