Base adds customers and grid capacity

The key advantage is that Base is not adding a battery to a fixed customer base, it is adding a customer and a grid asset in the same transaction. One install brings a new retail power account, another 25 to 50 kWh of dispatchable storage, more capacity to discharge into ERCOT price spikes, more aggregated value for grid balancing, and now incremental contracted capacity for Austin Energy as the portfolio ramps toward 40 MW.1 2 3

• The stacking matters because lease fees alone do not pay for the hardware. Base estimates roughly $10,000 upfront cost per battery before the $3,000 tax credit, while customer pricing is only about $650 upfront plus $19 to $29 per month, so the economic engine has to come from retail margin, wholesale arbitrage, and now utility capacity payments.1
• The new utility layer is concrete, not theoretical. Austin Energy approved an agreement for up to 40 MW of capacity at up to $4.08M per year, and city documents state that available capacity grows with each customer installation over an 18 month buildout. That means Base can monetize the same distributed fleet both as household backup and as contracted local capacity.2 3
• This is what separates Base from most home battery sellers. Tesla also pairs batteries with a Texas retail plan and VPP credits of $400 per Powerwall per year, but Base keeps battery ownership and builds its payback around a broader stack of recurring revenue streams tied directly to every new installation.1 4 5

If Base keeps scaling, the business can look less like a hardware installer and more like a distributed power fleet with built in customer acquisition. The next step is proving this stack travels beyond core ERCOT retail choice markets, either through more utility tolling deals or through other deregulated regions where one install can still compound value across several revenue lines at once.1 2 3
