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.

‍

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

Monthly Energy Bills

• Energy rate: 9¢/kWh plus your utility’s transmission and delivery fees
• If you have solar panels, Base buys back any excess energy you produce at:
  • 3¢/kWh plus a real-time wholesale rate bonus

Base operates today in select deregulated regions of Texas. A deregulated region means you can choose your energy provider. 

Base currently operates in the north of Austin area and DFW Metroplex (excluding Dallas City). We're expanding quickly to both regulated and deregulated regions and can join our waitlist here.

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.

How long your Base battery lasts depends on four main factors:

1. How much power you use: This is the most important factor. A battery stores a fixed amount of energy when the grid is down, so running high-usage devices (like A/C or laundry machines) will shorten backup time, just like a bigger water hose will drain a bucket more quickly. Reducing your power usage will extend it. We deploy larger batteries than the typical market size so that you can last longer.
   
   
2. Battery charge at the start of an outage: Backup time depends on how charged your battery is when the power goes out. Base actively monitors charge levels, maintaining an average 93% charge over the course of a month. Our outage protection software tries to ensure that your battery has sufficient charge to las most outages, even though we sometimes lower it to 20% to perform our grid-balancing operations.
   
   
3. How many batteries you have: Most homes get one battery (20-25 kWh), though some may qualify for two batteries (50 kWh). More batteries mean more backup power.
   
   
4. Additional generation sources: Base batteries integrate with solar panels, which can extend your backup duration during an outage.

We calculate backup duration based on your battery's charge level and capacity. The high range shows backup time 90% of the time, while the low range reflects a 10% chance of a lower charge during an outage. Backup time won’t go below the low range unless appliance usage increases.

Here is a breakdown of how energy usage translates to battery duration:

• Low usage (e.g., fridge, freezer, and lights):
  • Single battery: 30–40 hours
  • Two batteries: 60–81 hours
• Average usage (typical appliances, some A/C):
  • Single battery: 10–13 hours
  • Two batteries: 20–27 hours
• High usage (heavy appliances like A/C or electric heaters):
  • Single battery: 2–3 hours
  • Two batteries: 4–5 hours

When your power goes out, we’ll notify you and monitor your battery’s status. If it’s running low, we’ll recommend turning off high-usage appliances to extend your backup time. 

You can review our Electricity Facts Labels (EFLs) here. 

In deregulated markets—where you can choose your energy provider—power companies are required to provide an EFL. This document includes all the key details about a plan. EFLs are designed to help you make an informed decision when selecting your electricity provider.
