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.

Here’s How to Clean Away a Messy Toilet Using Today’s Incredible Technology

I’ve never seen a toilet this soiled by diarrhea.  But thankfully, there are now products that use pressurized steam to clean messes like this more-or-less instantly.

Apparently, they’re selling like hotcakes, but only to people incapable of asking themselves, “Where does all this fecal matter actually go? Does it seem like a good idea to blast it all over the bathroom?  And if the bathroom door’s not closed, all over the house?”

Home Schooling Is a Bit Controversial

Published

on

In an average month, I meet at least one person who is homeschooling their child.  I’m always tempted to ask about their reasoning, but I don’t, as it would bring up politics in at least 90% of cases, and I don’t like to alienate people by putting them on the defensive.

They probably know that homeschooling comes at a cost in terms of depriving the kid of the socialization that comes along with being surrounded with children their own age, but they believe they are protecting their kid from the multiplicity of dangers in public, and perhaps worse, private schools, starting with required vaccinations, then continuing into indoctrination into godlessness, socialism, science, and questioning the morality of America.

Obviously, as U.S. citizens, we have an extremely broad range of rights when it comes to how we raise our children.  If we keep them fed and get them medical treatment when required, we’re home free.

If I had any inclination whatsoever to challenge these people, I’d ask about their proficiency with history, writing, and math.  Even the common MAGA parent can teach his kid to read at a basic level and get through the multiplication tables, but how well is he equipped to take on geometry and the developments made by the Sumerians?

Clearly, such a discussion on this topic could get ugly very quickly.

To me, a pride flag says, “We accept LGBTQ people, and we bear them no malice.”

That seems just fine.
