Current obstacles

Customer adoption economicsHome batteries require significant upfront capital; customer payback depends on electricity prices, incentive programs, and usage patterns.
Geographic expansion complexityScaling from Austin to nationwide operation requires navigating different utility markets, grid codes, and regulatory requirements in each region.

Physics limits

Energy density of lithium-ionLithium-ion batteries store roughly 250 Wh per kg. More storage means proportionally more weight and cost; reaching multi-day storage at household scale becomes prohibitive.
Grid dispatch coordinationDispatch of thousands of small devices introduces latency and communication challenges; synchronizing real-time control with household power demands is complex.

How it works

2 parts

Home storage

Local energy shift

39.2 kWh stores solar generation and shifts peak demand to off-peak hours.

Network dispatch

Virtual power plant

Thousands of batteries dispatch as a single resource, providing grid stabilization without disrupting customer power.
