Power that stays on
Power you don’t have to think about.
Your rate stays low. Your power stays on. And you can monitor it all through a simple mobile application (for Apple or Android).
Your energy rate is fixed for 3 years, then legally guaranteed to stay below-market-average for as long as you’re with Base.
No time-of-use traps, no seasonal spikes. Just a flat, reliable price that makes your bill easy to understand, and even easier to trust.
You run on 100% renewable energy, with a battery that backs up your home and supports the grid.
Built for Texas homes, and the Texas grid
Your battery keeps your home powered during outages and supports the grid when it’s not. That’s how Base keeps energy affordable and reliable, year-round.
That earns money, and thus helps keep your rate low.

Locked-in rate: 8.5¢/kWh for 3 years

The way energy should be

100% renewable—and grid‑smart.
Your power is fully renewable. Between outages, Base uses your battery to support the Texas grid—discharging briefly, then quickly recharging. It’s how we help stabilize demand and keep your rates low.
Your backup is always protected; we never discharge during an outage.

Base offers a significantly less expensive backup battery solution compared to alternatives due to the unique shared business model: Base earns income from the power grid instead of homeowners.
This business model allows you to get energy backup without paying tens of thousands of dollars for a traditional generator. An expensive solar system and solar battery also requires a massive upfront investment which often can take longer than the lifespan of the system to pay back. With Base, you pay just a one-time installation cost that pays the team of electricians to install the battery on your home.
Base offers fair, fixed rates and reliable backup power. Since revenue comes from the grid, not customers, Base avoids hidden fees and surprise rate hikes. Your agreement also legally guarantees your rates stay below the market average.
No, you don’t need solar to use our batteries. You don’t need solar to use Base because the batteries are designed to store energy directly from the grid. This allows you to access reliable backup power and lower energy costs without relying on solar panels.
That said, if you already have solar, Base works seamlessly with it. Plus, you can always add solar later—our batteries are designed to easily integrate with solar systems. And Base offers competitive solar buyback prices.
