By Carmen

The University of Arizona Science and Technology Park – Battery Energy Storage System is a 10,000kW energy storage project located in Tucson, Arizona, US.

The electro-chemical battery energy storage project uses lithium-ion as its storage technology. The project was announced in 2015.


The University of Arizona Science and Technology Park – Battery Energy Storage System was developed by E.ON Climate & Renewables. The project is owned by Tucson Electric Power (100%), a subsidiary of Fortis.

The key applications of the project are demand response, electric bill management, electric bill management with renewable, ramping, renewable capacity firming, resiliency and transmission upgrades due to solar.

Additional information

Tucson Electric Power has entered into long-term agreements with E.ON Climate & Renewables and NextEra Energy Resources for the construction of two 10 MW energy storage systems. The systems will help maintain the required balance between energy demand and supply while satisfying other energy management requirements. The systems also can help prevent power outages during periods of high energy demand by supporting stable voltage on TEP’s energy delivery system. In the event of an outage, the systems could provide about 5 MW of power for up to an hour.
