Altair Nanotechnologies Inc.’s one megawatt (MW), 250 kWh lithium-ion battery storage system has met requirements to participate in the PJM Regional Transmission Organization (RTO) control area. This marks the first commercial acceptance of an advanced Lithium-Titanate battery to provide grid regulation services in one of the largest electricity markets in the US.
Altairnano has a joint development agreement with AES Energy Storage LLC, a subsidiary of the AES Corporation, to develop grid-scale energy storage applications. PJM Interconnection is a regional transmission organization (RTO) that coordinates the movement of wholesale electricity in 13 states and the District of Columbia, serving approximately 51 million people.
AES Energy Storage LLC completed the standard acceptance testing for regulation service within the PJM service territory earlier this week. The tests were completed by a one MW energy storage unit incorporating Altairnano’s Lithium-Titanate cells. This unit was part of an earlier AES technology validation effort in Indiana. The unit is now available for commercial operation as a qualified market participant for regulation service by AES Energy Storage.
Earlier this week, AES Energy Storage also installed its first Hybrid Ancillary Power Units (H-APU) from A123Systems. (Earlier post.)
