Outstanding customer service. Base Power always responds on time and never leaves you unattended after installation. They don’t just install the system and disappear — they regularly come back to check and make sure everything is running smoothly. I’m extremely satisfied. There was a power outage at night that lasted 3–4 hours and then came back, and I didn’t even notice it. Since we have two AC units at home, a soft starter was required, and Base Power installed it free of charge. Truly professional and reliable service. Highly recommended.

Levent Sakar, MEd. (STEM)

I had my batteries installed - February 2026. I am totally 100% pleased with Base - They exceeded my expectations with the installation and energy cost. Gavin and Emanuel did a superb job with the install - showed up on time and kept me informed of the process. When they finished they cleaned up the area better than I expected and made sure that I understood how the system worked before they left. My energy bill has decreased more than I expected. When the power goes out my batteries take over immediately. This has been the best purchase for my home since I moved here 6 years ago !! It’s clean - quiet - no maintenance required on my part and odor free!

Cathy Mendez

Great company, seamless process, that they have totally figured out. Update... I've received about 4 monthly billings and I couldn't believe the savings. This company is legit. My area has lost power for anywhere from 30 min. To a couple of hours, I knew nothing about the outage. System transfered so quickly that nothing in my house was flashing or flicked off and back on. It is totally amazing. Highly recommend you look into Base Power. Approximately 1year update: I referred my son who now has Base Power as well and he is amazed with the savings he has seen. We both have there Largest system they offer. System has been flawless, power has gone out since I have been on Base, if transfers over instantly. Only reason I knew power went out was our fiber optic internet rebooted due to the second delay power transfer. Love it... honestly recommend the system, glad I didn't go with back up generator I was thinking about installing.

I had planned to install a backup generator but due to cost had never proceeded. When I first learned about Base Power and the backup battery systems l became very interested. The cost was very reasonable and we chose to go with a dual 25 kVa system. The process was very easy and went exceptionally smooth from start through installation. Our electrical service switched several weeks ago and the batteries were installed today. I am very happy with this choice and having this option for backup power for our home. I highly recommend Base Power!

Kenneth Harbin

Great company to deal with, the install went smooth. There is a long vetting process to ensure their battery systems are a good fit for your location next to your electrical panel. I have had savings soon on my electrical bill, the app is great shows you what your daily power spending is. I had a generator connection to allow you to charge the system during the day and run on batteries at night on the event there is a long outage. Highly recommend this company.

R B

We’ve had our Base Power system for about 3 months now and I honestly can’t imagine going back. The peace of mind alone is worth it—we’ve already had one outage, and everything just worked. No noise, no scrambling, no stress. The install was super clean, the app is easy to use, and the team was actually helpful (which is rare these days). It was also the cheapest option when I compared other energy providers. One of the best decisions we’ve made for our home.

Rachel Jones

Top notch customer service throughout the entire process from initial contact to battery installation and beyond. Base Power personnel were very friendly, respectful, and responsive when I called for help with an issue after installation. A technician was sent out promptly and was able to fix the problem at no cost to me. I’m so glad I learned about Base Power before I committed to a whole-home backup generator which would have been 10x more expensive. I highly recommend Base Power.

Fantastic job by Rene Rodriguez (Electrician) and battery techs Matthew and Trey. The team was professional, arrived on time, and left the workspace spotless. Their technical knowledge and friendly attitudes made the whole process stress-free. Highly recommended for anyone looking for reliable, high-quality home battery backup system.

Anoop Moyan

Love having the battery backup! Great service and very simple process. Lowered my electric bill while stabilizing the power at my house. Best switch I've made after 8 years switching between different power companies. HIGHLY RECOMMEND!!!

Adam Roig

Base Power has been nothing but exceptional. I was skeptical at first, but they were always there to answer any questions or concerns that I had. Install was seamless and customer service is on point. I'm so glad to have backup power at such a reasonable price. It feels good knowing I'm protected while also helping the grid. Now I can sleep peacefully especially during winter knowing my pool pump won't freeze over cause of an outage. Thank you Base!

Matthew Miranda

The install of my base battery was seamless. The crew was very knowledgeable and answered all my questions. Base brings in all the equipment and they removed all the empty containers and pallets. I was very impressed and pleased with the entire process, from ordering to install. My electric bill has been very reasonable, actually a lot less than the service I switched from.

Debbie Bush

Great communication. Easy installation process. I loved monitoring my up to the minute electric usage. My house is powered, according to the App, 1/3 of the time by battery power and 2/3 by the grid. No indication of switching from one Source to the other. Smooth, smooth, smooth.

Janis Hillis

The batteries were dropped off on pallets the day before installation. The day of installation crew was right on time, was respectful, informative, and efficient. The area was cleaned up of all excess material before they left. So happy with all of the communication from the start. Highly recommend especially for the peace of mind during hurricane season.

Melody Chew

Huge shoutout to Base Power Company for a seamless installation today. We had two 25kW batteries put in, and I couldn't be happier with the service. Kyler led the team and did a phenomenal job ensuring everything was set up perfectly. The three technicians were professional, fast, and genuinely nice people to have working at our home. It’s rare to find such a combination of technical expertise and great customer service. I’m very grateful for the peace of mind they’ve provided. Five stars.

Ordered battery backup system from Base Power after I read local newspaper article describing it. Keeping it simple, they have a great home battery backup system that has capacity to power my fridge for 4-5 days, at very very low cost. Very good plan and good people doing the work. Note, this is not whole house power backup. AC on will draiin battery in a day. I suffered a 5 day and 2 day outage in past 3 years, must dump food from fridge/freezer. Now. I keep my food. I also have my portable generator as backup, but Base battery kicks on automatically when power outage occurs.

How Base shows up on your ComEd energy bill

You keep one bill, and it still comes from ComEd. The difference is your supply rate — Base handles that with time-of-use pricing that's at least 25% below what ComEd would charge you by default. Your battery does the rest.

What changes on your ComEd bill

On your ComEd bill, you'll see “Base Retail LLC” on the supply line. This is the cost of the actual electricity you use. This is the part that Base will handle for you.

How the savings actually happen

ComEd still delivers your power and sends the bill

Nothing about the physical grid changes. ComEd owns the infrastructure, manages outages, and sends you one bill — every month, same as always.

Base replaces the supply rate on your bill

On the supply line, you'll see "Base Retail LLC" instead of ComEd's default. On-peak rate: 7.8¢/kWh. Off-peak: 7.6¢/kWh. Both are at least 25% below what ComEd would charge you.

Your battery charges cheap and runs during peak hours

The Base battery charges overnight when power is cheapest — and you don't pay for that charging. During peak hours, when the rate is higher, it powers your home instead of the grid, delivering you a lower rate without changing anything about how you use electricity.

And when the grid goes down, your home keeps running

Same battery. When there's an outage, it automatically powers your home — up to 36 hours of backup with reduced energy consumption. No generator, no gas, no noise.

SIGNING UP IS EASY

Affordable reliable power is just a few clicks away

See if your home qualifies

We're happy to answer all your questions

If you are raising a complaint to our team, you have the right to receive our response to your complaint in writing. Base will respond to your complaint as soon as possible, typically within (1) day and always within fourteen (14) days. You also have the right to file a complaint with the Illinois Commerce Commission at 1-800-524-0795 or at www.icc.illinois.gov, and with the Illinois Attorney General’s Consumer Fraud Hotline at 1-800-386-5438.

A negative balance on your Base supply means your credits exceeded your energy supply charges for that billing period. This can happen when Base uses your battery frequently to support the ComEd grid. Credits on your ComEd account roll forward to offset charges in future billing periods. Base handles this automatically. Base cannot independently issue refund checks for negative balances.

ComEd performs two roles: it delivers electricity to your home through its grid infrastructure, and it sends you one consolidated monthly bill.

What you’ll see on your ComEd bill:

Base Energy Supply Charge

The amount Base Retail LLC charges for supplying your electricity. Base sets this rate to be indexed at least 25% below ComEd’s price to compare.

ComEd Delivery Charges

Fees for ComEd’s infrastructure: power lines, distribution equipment, and grid maintenance. These are the same regardless of which energy supplier you choose. Base does not control these and receives no portion of them.

Why they’re listed separately

Your bill separates energy supply (Base) from delivery (ComEd). Both appear as distinct line items on your single ComEd bill.

Your energy bill comes from ComEd — not directly from Base. ComEd consolidates all charges into a single monthly statement. Here’s what you’ll see:

Base Energy Supply Charge

Base Retail LLC’s charge for supplying your electricity. Calculated as your monthly usage (kWh) × Base’s rate, which is indexed to be at least 25% below ComEd’s price to compare.

Battery Dispatch Credit (if applicable)

When Base uses your battery to support the ComEd grid during peak demand, you receive a credit. This appears as a line item on your ComEd bill.

ComEd Delivery Charges

Fees for maintaining the infrastructure that delivers electricity to your home (power lines, poles, transformers, meters). These are set by ComEd and the ICC — Base has no control over these charges and receives no portion of them.

Taxes & Other Fees

State and municipal taxes, the Illinois Renewable Portfolio Standard charge, and other regulatory assessments.

Base is Illinois’s only Alternative Retail Electric Supplier (ARES) that provides members with a home backup battery system — at little cost. Unlike traditional energy suppliers, Base makes money by using your battery to help stabilize the grid during peak demand. This lets Base offer energy rates at least 25% below ComEd’s price to compare — not by cutting corners, but by earning revenue from grid services rather than from you.

What you get as a Base member

  • • A home battery system installed at your property (owned and operated by Base)
  • • Energy supply from Base Retail LLC indexed to be at least 25% below ComEd’s price to compare
  • • Backup power during outages
  • • A single consolidated ComEd bill that includes Base’s energy supply charges alongside ComEd’s delivery charges

Your rate commitment is built into your Energy Service Agreement when you join Base. Base earns revenue by providing grid-balancing services through your battery, so your rate stays competitive without the need to profit from your energy usage.

Base Retail LLC (an affiliate of Base Power) supplies your electricity as an Alternative Retail Electric Supplier (ARES), with ComEd maintaining distribution and emergency management responsibility. Your energy rate is indexed to be at least 25% below ComEd’s price to compare. ComEd publishes their price to compare periodically, and Base’s rate adjusts accordingly.

Your energy supply charges appear on your monthly ComEd bill — not as a separate Base invoice. You pay ComEd directly for your energy.

Last updated: 06/15/2026

Here’s an overview of the process:

After we receive your authorization, we will submit your switch request to ComEd. We will send you confirmation when ComEd approves your switch. ComEd will also send you confirmation of the pending switch. Your confirmed service start date will be dependent on your battery installation date and your meter read cycle. We will notify you as soon as we have a confirmed start date. It will typically be on the next billing cycle after battery installation.

Until your Base service starts, ComEd remains your electricity supplier. Once your Base service starts, your monthly energy bill will still come from ComEd — it’ll just have your new Base supply rate as a line item.

Activating Base in Illinois involves six (6) agreements* that work together:

  • Energy Service Agreement (ESA) — your supply agreement with Base Retail, LLC
  • Uniform Disclosure Statement (UDS) — a one-page summary of your rate, your right to cancel, and how to reach us
  • Battery Services Agreement (BSA) — your battery service terms
  • Net Metering Addendum — how credits work on your bill
  • Automatic Contract Renewal Notice — what happens at the end of your 24-month term
  • Letter of Authorization, Supplier Switch — your permission for us to switch your service
  • Letter of Authorization, Interval Data — your permission for us to access your usage data from ComEd

*These summaries are (1) provided for convenience purposes only and (2) do not describe the full contents of the agreement and (3) that the user agrees they have read and agree to the terms of the agreements themselves.
