Altairnano selected for 26 MW San Fermin solar project in Puerto Rico

Altairnano will provide a 2 MW ALTI-ESS Advantage advanced energy storage system to provide frequency regulation and ramp-rate control

Reno, Nev., October 3, 2012 — Uriel Renewables, Coqui Power and TSK Solar, chose Altair Nanotechnologies to provide an advanced battery energy storage system for a renewable integration project at the San Fermin 26 MW photovoltaic solar farm in Loiza, Puerto Rico.

Altairnano will provide a 2 MW ALTI-ESS Advantage advanced energy storage system to provide frequency regulation and ramp-rate control. The system will satisfy the technical requirements established by the Puerto Rico Electric Power Authority. Altairnano will deliver, install and commission the system before Dec. 31, 2012.

The ALTI-ESS Advantage is Altairnano's newest product for the electric grid market. Building upon the success of its 1 MW ALTI-ESS, the Advantage system provides twice as much power in a container almost 25 percent smaller, and can achieve peak power of 3.6 MW.

The batteries are housed in a standard 40-foot container that also includes fire safety, heating and cooling, and computer systems necessary to safely and economically operate the system.

The ALTI-ESS Advantage will provide ramp-rate control for smoothing the power fluctuations associated with photovoltaic applications in addition to frequency regulation required by PREPA.
