What to Expect on the Call


During your consultation a Base representative will answer any final questions you might have and guide you through your potential savings by switching to Base as your provider.

Site Survey

At the end of the call, we'll take a couple of pictures together of your main panel and sub-panel ("breaker box") to ensure that our battery can configure with your existing electrical system. If you have an Iphone, we'll facetime you. If you have an android or other phone, we'll guide you as you take the following photos and measurements:

(1) A photo of your meter (circle with number on it on side of your home).

(2) Open up your main panel by the meter and take a photo of it. Be sure that the numbers that indicate the amperage and the labels for each breaker are visible in the photo.

(3) Take 15 paces back from the wall with your main panel and meter (or as far as your property line will allow) and take a picture, ideally capturing all available wall space on the side of your home with the main panel. We need a photo that is flat to the wall (no side angles). If you are unable to capture all available wall space, or there is a fence, repeat this process for the section of wall that was not captured.

(4) Measure the distance between any two points in the above photo so that we can scale it.

(5) Finally, take a photo of your sub panel, which is typically found in the garage. Be sure that the numbers that indicate the amperage and the labels for each breaker are visible in the photo.

The Base representative that conducts your consultation and site survey should be able to answer questions about the location of the items listed above.

The Base engineering team will review these photos to ensure that we can configure with your existing electrical system. You will be notified within 48 hours.


Battery Enrollment

To confirm your enrollment, you'll be prompted to:

Sign the battery agreement, which is described further below.

Pay a $250 deposit, which will be applied toward your $2000 installation fee for the battery.

After signing the agreement and submitting the deposit, We'll notify the permitting team, who will begin submitting paperwork to the utility and municipality for approval.

Battery Agreement Details

Read the full Agreement by clicking this link.

Our battery agreement is 15 years. You will need to be signed up with Base’s retail electricity provider for the full duration of the battery contract. When the contract expires and if you decide against renewal, we’ll come retrieve the battery from your home at no cost to you. There is also no de-installation fee if:

You decide to move after 5 years,You decide to move before 5 years and the next homeowner will take over your agreement.

The battery is damaged from unforeseen circumstances or Base is unable to meet its obligations to keep the price of its REP offering below the market average.

Worst case scenario, if the agreement is breached, the de-installation fee is $1000. In the unlikely event that Base is unable to retrieve the battery, you will be charged its market value.

Does electricity that's stored in the Base battery flow back to the grid?

The reason we were able to offer the battery at such low up front cost is that we use it to perform grid balancing operations, which we can monetize in energy markets. This pays back the $15,000+ up front investment that Base makes in the hardware, while you still get the benefit of outage protection.

Why is there no reference to my electricity rates in my battery agreement?

The battery agreement is entirely divorced from the retail energy agreement with the exception that the battery agreement can be severed if Base does not meet its obligations to maintain rates in stride with the industry average. Once the battery is installed, we will transfer you to our retail electricity service and you'll receive the rate that we quoted you in our consultation and site survey.

Is there a minimum state of charge guarantee?

Base will make every effort to maintain a minimum state of charge of 20%. We'll also make attempts to charge your battery in anticipation of predictable, long-duration outage events. We are unable to write these commitments into the agreement because unlikely technical faults in the battery could cause the state of charge to dip below 20% or fail to charge in anticipation of an outage. Most other batteries/generators will have similar "no-guarantee" terms.

What happens if something goes wrong during installation or over the useful life of the battery?

Installation issues would be covered by the liability insurance of the contractor. If helpful, our licensed, bonded, insured and certified electrician contractor license through the Texas Department of Licensing & Regulation is #476697. Our hardware is UL certified & fire safety rated, adhering to the latest standards. We also have comprehensive general liability insurance to address any unforeseen incidents. In the unlikely event of a problem, we're prepared to handle it responsibly. Separately, Base is in charge of warranty & maintenance.

Are there protections from Base raising its REP rates at renewal?

Base has committed to always being at or below the 50th percentile of comparable retail plans every time we renew your plan. We're also incentivized to keep you as a customer since our income stream is tied to the number of years that the battery remains on your property.

Retail Electricity Provider (REP) Enrollment

Once we install the battery, we'll transfer you over to our REP at the flat subscription price we quoted you in the consultation and site survey.

REP Contract DetailsPlease read our Terms of Service and Your Rights as a Customer.

Is there a limit to the amount of kWhs I can use at the flat subscription rate?

Yes. If you use above 115% of your consumption in the same month from the previous year, you will be charged a per kWh figure that is stated in the contract. We ensure that this usage cap is well above what you have used previously.


Once you have submitted your contract and deposit, our team will work to coordinate with your municipality and your distribution utility to acquire the proper permits. Although Base will assume the leading role in driving these permits forward, we'll need your signature on a couple of documents.

Gaining the proper permits can take between 2-8 weeks.

Utility Permits

Base will submit permits on your behalf to gain permission to connect the battery to the distribution grid. We'll need your signature on two documents in order to gain approval:

Tariff Application - Your distribution utility will verify that you have granted us permission to submit permits on our behalf. Please e-sign that document as soon as it lands in your inbox

Interconnection Agreement (AI) - You will also need to sign the final agreement for interconnection.

It's crucially important that you sign these documents in a timely manner. Your distribution utility will not proceed with the permitting process until they receive your signature.

Municipality Permits

Each municipality has slightly different requirements. Depending on your location, we may need your signature on various documents, or we may not need a permit entirely. Your Base Representative will contact you if there are any required actions.


When Base has obtained the proper permits from your municipality and distribution utility, a Base representative will personally coordinate with you regarding your installation.


You will likely schedule your installation date 1-2 weeks ahead of time. When the installation is scheduled, you will receive a calendar invite and an email with any other information specific to your installation.

Installation Day

Battery Installation will only take one day from 9AM to 5PM. There will be a period during which power will be cut to your home as we configure backup functionality.

Base electricians will be in touch with you via text to inform you of their arrival and departure, connect the battery to your wifi, and give you notice of power being cut to your home – it's important that you are accessible via text on installation day. When your installation is complete, one of our electricians will give you a short demo of the system. It is helpful, but not necessary if you are home.

How to use the Battery

Our Rep will provide you energy from the grid when the grid is working and our battery will back you up when it’s not. The switch from on-grid to off-grid is automatic – the .3 second delay during the transfer will seem to you like a flicker or dimming of your lights. Although our coverage is largely automated, there are a few reasons we may need your help to ensure proper functionality. If you notice that your battery is not powering your home and there is still capacity stored within it, call Base immediately and we will talk you through how to resolve the issue.


A Base representative will reach out to you with a stripe link to collect your final payment.
