Tucson Electric Power (TEP) has boosted its service reliability with energy storage capability at three facilities.
A 10-megawatt lithium nickel-manganese-cobalt energy storage system was completed at a TEP substation near Interstate 10 and West Grant Road. The system is designed to help maintain reliable service during periods of high energy demand by supporting stable voltage.
Slated to be completed in the spring are a 10-megawatt lithium titanate oxide storage facility and an accompanying 2-megawatt solar array at the UA Tech Park southeast of Tucson.
A 1-megawatt lithium ion energy storage system is under construction at TEP’s Prairie Fire Solar Array and a 5-megawatt system will be located near Interstate 10 and East Valencia Road. They will be used to study how efficient use of battery energy storage systems can improve electric reliability in Arizona’s extreme summer climate.
