Your guide to everything Base.

Base is your energy provider and backup power provider in one.

We install a large 39.2 kWh battery at your home for a low upfront cost. You get power from us at competitive rates because our batteries help balance the grid—charging when demand is low and discharging when the grid needs support. When the power goes out, your battery automatically kicks in to keep your home running. Our current system protects against 97% of outages.

To get with Base, you pay a $50 refundable deposit upfront. This deposit applies toward your one-time installation cost once your battery is installed.

Installation costs

• Installation fee: $695 or $995 (varies by zip code and plan)
• Your $50 deposit will be credited toward this fee

Ongoing costs

• Membership fee: $19/mo or $29/mo, depending on your plan
• Energy rate: 7.7¢/kWh plus your utility’s transmission and delivery fees
• If you have solar panels, Base buys back excess energy at 4¢/kWh

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. 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.
