Simple, transparent energy pricing

No gimmicks, no hidden fees—just clear, honest pricing. Base plans have an average energy charge of 9¢/kWh, with bills always accessible via our iOS and Android app.

Forget ‘free nights’ and confusing buy-back rates—Base keeps it simple with transparent, predictable energy rates.

Protection from ~97% of outages

The average power outage in Texas lasts 2.5 hours. Even with our most compact battery and typical power consumption, Base members have at least 20 hours of backup power.

That means eight times the coverage of a typical outage—without relying on the grid.
