Thank you to @WSJ for covering the launch of Base Core and our $1B Series D.
The U.S. is undergoing a foundational shift in energy demand, and traditional power generation can't scale fast enough to meet it. Meeting demand this fast calls for new technology that works alongside the grid and adds capacity where it's needed most.
Base Core does just that: one of the largest home batteries on the market at 39.2 kWh, designed and built by Base in Austin, and engineered for rapid deployment at scale.
This new capital will go toward bringing Core to more homes, expanding nationally, and hiring exceptional talent.
The Series D is led by @RibbitCap, Addition, Valor Equity Partners, and @jpmorgan’s Strategic Investment Group, with participation from @AltimeterCap, D1 Capital Partners, Sands Capital, @coatuemgmt, Layer Global, and @EnergyImpact_ . Base’s major existing investors are re-investing, including @ThriveCapital, @a16z, @lightspeedvp, Trust Ventures, @CapitalG, and more.

Delivering affordable, reliable power takes engineers, and we want to hire the next ones here in Texas.
The Base Power x AITX Talent Hackathon runs September 25 to 27 at our Austin headquarters. For 48 hours, we’re inviting engineers into our office for a weekend of heads down building.
Apply here: luma.com/aitx-94j6
Thank you to @aitxcommunity , @ThriveCapital, and @a16z.

The first half of the 20th century saw exponential growth in electricity demand in America, and so we built the largest synchronous machine on the planet. This exponential growth is back. Enormous new productive load is being connected to the grid and new generation, transmission, and storage capacity is needed to make, move, store, and ultimately sell energy to people at an affordable price.
ERCOT is leading the way with the ADER program, and the introduction of Phase IV is creating a powerful new tool to help meet these needs.
@cpatdowling , our founding power systems engineer, outlined how what’s happening in Texas can help solve the capacity crunch: basepowercompany.com/blog/ag…

Proud to be working with @ARizzo44 to bring more reliable, affordable power to Chicagoland. Welcome to Base, Chicago.
Excited to partner with @basepowerco as they launch in Chicagoland. More than 500,000 Chicagoans have dealt with outages just this summer, all while energy bills keep going up. Base is trying to do something about both.
For $95, they install a home battery that can keep your power on during an outage for up to 36 hours—and help save on your monthly energy bills.I’ll be honest, when they first told me, I was skeptical too. Then I met the team, saw how it worked, and wanted to be part of bringing it to Chicago. I spent a lot of years covering first here. Now it’s time to cover home.
Chicago saves on Base. Chicago’s safe on Base. Learn more: bit.ly/anthony-rizzo

Dino, our Head of Hardware, designed and built Base Core to protect families and cut their power bills, with his own family in mind first.
In this first episode of Building Base Core, meet Dino and his family, and see how they lived with and tested Base Core before bringing it to others.

Last week, Base Power Company announced that it had raised $1B at $13B and launched Base Core.
The perfect opportunity to write Chapter 3 of the Book of Base.
This one is about bringing manufacturing in-house, capturing the High Ground, building a Capability Cannon, aiming it at new geographies and customer types, and where it might aim next.
There are only two companies I've written multiple Deep Dives on: Ramp and Base. I plan to write a Chapter every year until IPO, and then turn it into a book.
The ambition grows each time I come back, and now it's about as big as it gets. Base wants to become the world's largest energy company.
"Because if we are the best energy technology company, and energy is going through this kind of once in a generation demand inflection as the result of AI, the company who does this should become the world’s largest energy company and perhaps the world’s largest company," Zach told me. "But we'll see."

Somewhere along the way, a collaborative tradition took hold between @basepowerco and @terraincap: a poster for every major milestone. Today that collection grows:
> The first, at launch, captured a future with storage in every home.
> The second focused on deployment electricians, echoing the WPA posters of the 1930s.
> The third came last year alongside the newspaper: a call for talent to join Base.
> And now, marking the launch of Base Core, one of the largest backyard batteries ever built.

The cost center of energy has become more about delivery than production. Excited to see @basepowerco launch Base Core today, and to keep backing Base Power and others re-industrializing the US grid.

Honored to have @JJWatt on team @basepowerco and had fun showing him around Base Factory 1.
Base told me they save people money on their electricity bills, keep the lights on during power outages and strengthen the overall power grid.
I couldn’t understand how that was possible or why everyone wouldn’t switch to Base, so I wanted to find out for myself.
I’m now a customer, investor & endorser.
I toured the factory, met the team, visited a home install and asked a whole bunch of questions.
I went on the Base website and typed in my address to see how much they could save me on my electricity bill and it said 35%. I switched right there on the spot. No special VIP pricing, no endorsement trick, I literally logged on and did it myself on the regular website right from my phone.
The one question I kept coming back to was “Save money, protect your home during outages, help support the power grid. Why wouldn’t everyone want to get Base?”
I still haven’t found an answer to that yet.
Today they're launching Base Core, a new home battery fully designed by Base and built right here in Texas.

We need energy abundance.
Let @ZachBDell @basepowerco 👨🍳
Today, we're launching Base Core, our own battery designed & built in Texas, and announcing our $1B Series D to bring it to homes across the country.
Three years ago, we started Base with a belief that batteries were the unlock to energy abundance. We saw battery storage as the foundation of a modern energy system, and believed we could win the market with vertical integration, technology, and relentless execution (what we now call Base Pace). So we set out to build a network of distributed batteries to deliver affordable, reliable electricity to homeowners and utilities.
While the job is far from finished, the launch of Base Core is the most meaningful step in that plan. We’ve spent the last few years learning hard lessons about building a distributed battery fleet, going from 1 install per day in June of ‘24 to 100 installs per day in June of ‘26. These lessons - how the battery is shipped, installed, used, and monitored - informed the design of Core. Now, Core will be the foundation of the company's next phase of growth.
Base Core is a first-of-its-kind home battery. At ~40 kWh it is 3x the size of most home batteries, providing up to 36 hours of backup for the average home. In the event of multi-day outage, Core is equipped with a (first of its kind) generator port - pull out a small portable generator and charge the battery back up to keep your home running as long as you need. When an outage does happen, the backup is seamless - most members won't even notice the grid went down. It's built to withstand Texas summers, Chicago Winters, and everything in between. And finally, it’s manufactured by our team in Austin, at Base Factory 1, right across the street from our HQ.
This new capital will bring Core to more homes and to accelerate our ambition beyond batteries. The round is co-led by Ribbit, Addition, Valor, and JP Morgan, with participation from new major investors D1, Sands, Coatue, Layer Global, and Energy Impact Partners. All of Base’s major existing investors are re-investing, including Thrive, Altimeter, Lightspeed, a16z, CapitalG, Trust, and more. This brings our valuation to $13B.
As we enter the most important growth period in the history of the electricity industry, our mission has not changed - advance human prosperity by delivering the world's most affordable and reliable electricity. Our strategy has not changed - technology, plus vertical integration, plus relentless execution, leads to a compounding cost advantage. What has changed is the scope of our ambition - this new capital, along with the team and capabilities we've built over the last three years, positions us to build technology across the electric stack, including what it takes to serve surging demand from AI, and to deepen our partnerships with utilities as they work to meet rising demands.
Electricity is the largest and most essential industry in the world, and it does not have a defining technology company. The company that delivers the most affordable, reliable power will be one of the largest and most impactful companies in the world. We intend to build it. If you'd like to join us, reach out.
Onwards.

Many companies will announce a factory by standing in suits and shoveling some dirt.
That always seemed strange to me, so we built the factory, got it running, and now we’re ready to announce it.
We've raised a $1B Series D at a $13B valuation to expand to more homes, and launching Base Core; built here in Texas.

This week's storms left over 530,000 without power across Chicagoland.
Omar Bashqawi, an IT executive in South Elgin, recently became a Base member and had his Base battery installed in April. The battery kicked in during outages and kept his entire home running. The Base battery does more than provide backup, it also lowers monthly energy bills. Omar’s ComEd bill has dropped from $350 a month last summer to about $250 this summer.
Thank you to Robert Channick at The Chicago Tribune for covering the story this week, along with Base's expansion into Chicagoland.
