The most affordable home backup in Texas (and we mean a lot more affordable)

The way power should be

Traditional energy providers are middle-men guilty of confusing plans, hidden fees, and gimmicky sales tactics.
Base is a new kind of power company — transparent, reliable, affordable.

Join our reliable and affordable retail electric provider (REP).

Base is the first power company to include a home backup solution. We also don't believe it should cost you to switch, so we cover up to $250 in early termination fees.

Specific rates are dependent on your zip code. See rates in your area by entering your information here.

No rollover, less than market

No gimmicks, no seasonal prices, no hidden fees.

Our rates are transparent and below market average (and guaranteed to stay that way).

Fastest solar payback in Texas.

Because of the battery, Base is able to offer one of the best solar buyback programs. We pay for all export, whether to the grid or to the battery at a rate of real-time wholesale plus 3 ¢/kWh

Installation cost and energy charges are the same for solar homeowners. While solar is not required, Base integrates with existing solar panels, and homeowners can always add solar after installing Base.

FAQ

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 contract also legally guarantees your rates stay below the market average.

To get started with Base, you pay a $50 refundable deposit to secure your spot and kick off the permitting process. If you decide to not move forward prior to permitting, Base refunds the deposit. 

Once your battery is installed, this deposit goes toward your one-time installation cost, which typically is $3,000 depending on your zip code and battery size. 

Base also offers payment plans to make installation as affordable as possible. Base does not want cost to be a barrier to people who need energy backup. 

After installation, you pay monthly utility bills just like you would with any energy provider. The difference is that Base guarantees your rates will be below the market average. 

If you have solar, Base will also buy back any excess energy you produce at real-time wholesale rates + 3¢/kWh. To see how much you can save, send Base your latest energy bill at team@basepowercompany.com, and a Base energy advisor will provide a personalized cost comparison.

Check Availability

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 prediction technology tries to ensure that your battery has over 90% charge before 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.

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.
