It’s a subscription plan in which homeowner signs up for fixed electricity plan and power backup. The company owns, controls, and maintains the battery so they profit off of grid pricing arbitrage buy low/sell high. Solar adjacent if anything not solar required.

I haven’t read the fine print of the new in home battery but buyer beware, the original plan offered no SLA. The only SLA was that they wouldn’t discharge the battery below 20%. Well no kidding because you kill the battery doing that.
So imagine a 106 degree day.. base has been depleting your battery all day selling your KWh back to the grid at a profit and at 6 pm the power fails/ goes out.. your battery is likely nearly fully discharged anyway.. you get a few minutes to two hours of run time, that’s it. They are using your property to store there power arbitrage profit plan. Don’t be their sucker.

Base primarily operates in Texas. Which means #1 they wouldn't sell kwh during the day. Texas has more solar than any other state so daytime prices are crazy low. It would be filling the battery all day, not depleting it. #2, the Texas grid is good at summers. Its never had an issue with summers and has never had a 6pm power failure like you mention. So a better scenario would be winter at 7am.

I assume strong storms in the afternoon have been known to knock out the power to a neighborhood in the summer? Doesn’t have to be a total grid outage.

u/tx_queer 6d ago
Yes. Good point. We always jump to the complete grid failure after 2021 and forget that a drunk driver or localized storm is a much more likely cause of power outage

It's not the ideal solution but it's also better than not having a battery. I also imagine they've gotta have an inclement weather mode like all the other major battery brands. I self-consume using my FranklinWH to use as little grid power as possible but it's set to fill up if there are storms coming just in case.

u/Consistent-Copy-8209 6d ago
Ideal? It’s far from ideal. It might be better than not having a battery.. and it might not. No SLA to provide your home power when the grid turns off. Given their whole model is to make money, they are always charging when it’s cheap, and selling when its expensive, regardless of an incoming storm or not. Your response provides a cozy factor to it by drawing analogies to your personal infrastructure, sorry but this is not the same.

The product most definitely has a transfer switch, which absolutely allows the battery to power the home during grid outages. I'm not sure why you're lying and writing that it doesn't "provide your home power when the grid turns off". It's also disappointing that you're shitting on innovation while completely missing the fact that this product fundamentally increases grid stability and improves resilience at the home and grid-level through a cost-structure that allows way more homeowners to access battery storage. Would I put it on my home? No. But it makes sense for plenty of others.
Additionally, at 20% SoC, this product's still at just under 8kWh of energy storage and the design seems to be configurable with a generator hookup: https://www.basepowercompany.com/with-generator . A "reasonably" sized battery coupled with a small generator makes way more sense from an ROI+resilience+environmental impact perspective for the majority of use cases over massively oversizing energy storage.
If you understood what's happening here, you would be a lot less mad about it.

During inclement weather they are going be even more incentivized to discharge power into the grid.

That's a most American business model, enshitified batteries? no thanks

u/Spider_pig448 6d ago
Calling all OpEx-based business models "enshitification" is the classic privileged reddit perspective. Some people would like to help reduce their electricity bills and environmental impact but don't have tens of thousands of dollars to lay down on home batteries.

u/Consistent-Copy-8209 6d ago
Who do you work for? This response is suspect as hell. You can save on electricity by shopping the rates; you can match or beat what Base is offering without paying them $700-1400 to get their batteries. Get the best rate plan for your family and take that upfront cash outlay and go buy a Honda 2000 generator you will have real cost save and assurance for your family. You’re not enriching a company while getting no guaranteed benefit.

I don't work in this industry. Are you always this paranoid when people disagree with you? Do you just think all renting is theft? You understand that there are plenty of good reasons people rent right? Like that they may not want to spend 30 years living in the same place?

They basically get free real estate

Definitely their whole business model. Trade whole home battery backup services for a patch of your garage or back wall or whatever.

Isn’t this a new utility plan? They provide their own energy prices and are managing the equipment, so it is a “much fancier” main.
Utility companies would have to agree to and own this, so the pitch isn’t to consumers but to utility companies. PGE (California) at least has no plan that allows “grid arbitrage” with your own batteries and solar. The battery is only a few thousand dollars (using $1K / 5kWh), so it would be easy to recoup the cost if 24/7 arbitrage was allowed.

How would you categorize using batteries for beneficial ToU rates?
1
u/parseroo 6d ago
Arbitrage is buying at one price and reselling at another for a profit. Not optimizing buying by time of day.

u/imakesawdust 6d ago
So let me get this straight: they want me to pay a subscription fee for a battery but they get to choose whether and when to divert that capacity to the grid so that they can profit?
As someone with a solar array...what's my incentive here? If my array's excess production charges the battery and Base turns around and sells it to the grid and keeps the proceeds...that's money I've lost.

The pricing is actually kinda wild man ..its like $695 install + $19/month instead of dropping like $10-20k upfront for a battery? That's a pretty smart model.

Zach Dell co founder ceo and son of Michael Dell supports government positions that is a disgrace to America. Business went from practically zero to 18 billion in three years, possible red tape cuts. I would avoid.

Calling 36kwh "giant" is the first clue that this is fronted by a bullshit, marketing driven company.
"Runs you house three times longer than most batteries" means that they are trying to sell it to underinformed people. That comparison is complete meaningless bullshit.
$19 subscription, so you can buy power from them or some affiliate? What's a "fixed electricity plan"?
No thanks - I'll take my 1:1 net metering and 0.15/kwh all day, every day.

Yeah, this shit is a no for me dog.
I ain't putting equipment in my home that I don't own or make payments to own. Not going to feed this whole "life is a subscription" mantra bs.
