Tucson Electric Power (TEP) plans to build the 200 MW Roadrunner Reserve II, the company’s second large BESS, in southeast Tucson.
The system, slated to store 800 MWh, is scheduled to begin operation in 2026, a year after the similarly sized Roadrunner Reserve is expected to begin operating on the same site.
The side-by-side systems are slated to be the largest energy storage resources in TEP’s portfolio.
“Our new Roadrunner Reserve II system will help us make the most of intermittent resources, especially during the summer when usage is highest and customers are counting on us the most,” says Susan Gray, TEP’s President and CEO.
“We need additional energy storage as part of a diverse energy portfolio to support service reliability.”
The projects will be built next to a southeast-side TEP substation. Construction of Roadrunner Reserve is ongoing, while construction of Roadrunner Reserve II is scheduled to begin later this year.
Currently, TEP has 50 MW of storage capacity, including a 30 MW BESS at the Wilmot Energy Center.
The company will own and operate both systems, which will be designed and built by Scottsdale-based DEPCOM Power. Both systems will use lithium iron phosphate battery units.
TEP and its parent company, UNS Energy, are subsidiaries of Fortis.

Some people may be, but, to a person, the foreigners I’ve met are deeply saddened, and terrified of the consequences of the Trump regime.
Their feeling is simply that America re-elected a convicted felon, rapist, and traitor who attempted to overthrow the U.S. federal government. If we’re willing to do that, we’re capable of anything, regardless of how depraved.
I’ve never understood why those who compose total bullshit like this don’t go for the gusto. Why 95% and not 99% or 100%?
Trump’s actual approval rating among Republicans is somewhere between 75% and 80%, as can be easily verified by anyone on Earth with a cell phone or computer. That number continues to dwindle, as he faces more pressure regarding the war, gas prices, child rape, etc.
Obviously, the president’s supporters are suckers for his lies, but isn’t this a bit over the top?
I get a call every week or so from someone working for a start-up in oil exploration, hoping that I’ll invest. I guess my name and cell number got collected somehow from various online searches I’ve made.
I’m always quick to explain, “Oh, sorry, I don’t support wrecking the planet, even if I can profit from it. Neither should you. Bye now.”
