Every plan comes with the full Base experience
When the grid goes down, your battery kicks in instantly—keeping lights, fridge, and Wi-Fi on. No gas, no noise, no drama.
Get the most affordable backup in Texas. Similar backup solutions cost upwards of $18k. Base covers maintenance and service for the life of the battery.
From first call to the moment your battery kicks in, everything just works. Easy installations, real-time updates, and people who show up.
If you receive your monthly energy service from GVEC, you will continue to do so with the installation of a Base battery.
When the grid is up and running, our grid-balancing software automatically detects spikes in demand through price surges. During these periods of high energy demand, the batteries pass some energy back to the grid, stabilizing it. When there’s plenty of energy to support the grid, the batteries recharge.
Our batteries are engineered for rapid charge and discharge. This design enables them to respond instantly to brief demand fluctuations and balance the grid faster than any other energy source.
Base discharges its batteries to save you money, and to support the grid.
Support the grid. You can think of grid-balancing as sharing energy with your neighbors during brief moments of high energy demand. When Base discharges energy during these short peaks, it helps prevent blackouts and keeps the grid running smoothly for everyone.
Grid balancing might seem tricky to understand, but Base’s mission is simple: install as many batteries as possible to strengthen the grid and lower costs for Base members (both for backup and for monthly energy). More batteries mean a more reliable grid and more affordable energy for our members.
No. Your energy provider does not change when you get a Base battery. If you see language about energy provider services on Base’s website, this is because Base also serves customers in competitive (deregulated) service areas of Texas. If you live in a competitive area, your zip code will return plans here.
During an outage, the batteries automatically detect the loss of grid voltage and immediately disconnect your house from the grid. At that point, the battery supplies energy exclusively to your home—you are legally entitled to this energy, and our batteries will never discharge to the grid during an outage. Once the outage is over, your battery seamlessly reconnects your house to the grid and resumes normal operation.
