Base never sells batteries
Base Power
Keeping the battery on its own balance sheet turns Base from a one time hardware seller into a utility like asset operator. That matters because the monthly fee is far too small to repay a $10,000 installation on its own. The real payoff comes from combining three cash flows around the same box, membership fees, electricity margin, and selling stored power back into the Texas grid during expensive hours, while also making the customer offer look dramatically cheaper than a bought outright battery.

A typical Base plan charges $695 upfront and $19 per month for one 25 kWh battery, plus an electricity plan. That pricing only works because Base keeps ownership and earns from the grid behind the scenes, instead of asking the homeowner to fund the hardware up front.

This model makes Base look less like Tesla, Enphase, or Generac, which mostly sell equipment, and more like a fleet owner. Base says lease fees alone would imply a 20 plus year payback, so the business only closes if retail power margin and wholesale arbitrage do the heavy lifting.

Owning the fleet also gives Base tighter operational control. It can remotely manage charge levels, reserve backup power, dispatch many homes at once into ERCOT, and standardize installation and maintenance. That is what lets each added battery increase both customer count and tradable grid capacity.
The next step is proving this fleet model can travel beyond Texas. In ERCOT, battery ownership unlocks the full stack of customer payments and grid trading. In regulated markets, Base will need utility contracts to replace that missing value, which means future scale depends on turning battery ownership into an infrastructure business, not just a clever retail offer.
