Base Power recently raised a $1 billion Series D at a $13 billion valuation and is launching its new standalone home battery, the BaseCore. In this episode, the guest walks the host through their Austin, Texas manufacturing facility, explaining their vertical integration strategy and how they produce home batteries designed for whole-home backup and grid support. They discuss the differences between retail choice and non-retail choice electricity markets, the mechanics of how the batteries are assembled using both automated robotics and manual steps, and their plans to scale production significantly.
Base Power announces a $1B Series D, $13B valuation, and introduces its new BaseCore home battery.
Walkthrough of the Austin facility, staffing, and rapid build-out of the production line.
Explanation of how BaseCore plugs into homes, provides backup, and supports the grid.
Host wraps up, promotes newsletter and podcast platforms, and signs off.
Discussion of retail choice vs non‑retail markets, partnership with utilities, and revenue streams.
Overview of the automated assembly line, robot use, and vertical integration benefits.
Brief mentions of Brex and Public investing sponsorships interspersed throughout the episode.
Current output, projected 4,000 units per week, and plans to double installations.
Insights into the workforce, roles, and the company’s hiring focus.
Massive New Standalone Home Batterydata
The guest introduces the BaseCore, a 40 kilowatt-hour system with a 20-kilowatt inverter that is three times larger than traditional home batteries.
Rapid Factory Setupstory
The production line and factory floor were built in just a few months, starting construction in February or March of the current year.
Whole-Home Backup Architectureinsight
Unlike other batteries that require homeowners to choose specific circuits, the Base Power system connects directly to the electrical panel for full-home coverage.
Electricity Market Business Modelsstrategy
The guest explains how their business model differs between retail choice markets where they sell power directly and non-retail markets where they partner with utilities.
Extreme Reliability Testingstrategy
Thermal chambers simulate extreme environments, such as 85 degrees Celsius and 85 percent humidity, to ensure the batteries can function maintenance-free for 15 years.
Balancing Automation and Manual Laborinsight
The factory uses a mix of automated robotics for tasks like glue application and manual labor for high-dexterity steps like screw placement and connector installation.
The guest notes that the facility aims to produce around 4,000 battery units per week by the end of the year, translating to one unit every few minutes.
“Base Power just raised a $1 billion Series D at a $13 billion valuation led by Ribbit, Edition, Valor, and JP Morgan Chase, bringing total funding over $2.5 billion,”
“We can cut down costs. We can reduce lead time. We can change the hardware much more quickly because we can change, we can have the engineer drive the golf cart or, or run over here and go change something on the line, uh, from HQ.”
Justin Lopas, Co-Founder and COO of Base Power, joins Sourcery at Factory 1 in Austin for the launch of Base Core and the company's $1 billion Series D. The round values Base at $13 billion post-money and is led by Ribbit, Addition, Valor Equity Partners, and JPMorganChase's Strategic Investment Group. Existing investors Thrive Capital, a16z, Lightspeed, Trust Ventures, and CapitalG re-invested, bringing total capital raised past $2.5 billion. Base Core is the largest standalone home battery on the market at 40 / 80 kWh. Justin walked me through the factory floor, the install demo, and why Base builds the hardware itself. "It is so critical to bring manufacturing back to the US, especially for critical infrastructure." We cover: › The $1B Series D at a $13B post-money valuation › Base Core, 40 kWh of storage and 20 kW on the inverter › Whole home backup versus circuit-level backup › Retail choice markets versus utility partnership markets › Installing batteries around data centers to offset interconnection load › 4,000 units per week by the end of the year › Over 100 installs a day › 100% US and Mexico supply chain › Factory 1 built in under 6 months Justin Lopas: https://x.com/JLopas Molly O’Shea: https://x.com/MollySOShea Sourcery: https://x.com/sourceryy 𝐄𝐏𝐈𝐒𝐎𝐃𝐄 𝐋𝐈𝐍𝐊 YouTube: https://youtu.be/zfFGgfI2Xog https://youtu.be/zfFGgfI2Xog 𝐒𝐏𝐎𝐍𝐒𝐎𝐑𝐒 • Brex https://brex.com/sourcery—The modern finance platform, combining the world’s smartest corporate card with integrated expense management, banking, bill pay, & travel. https://brex.com/sourcery • Turing https://turing.com/sourcery—Turing delivers top-tier talent, data, and tools to help AI labs improve model performance—and enables enterprises to turn those models into powerful, production-ready systems. https://turing.com/sourcery • VCX https://fundrise.com/vcx—VCX is the public ticker for private tech, allowing investors of all sizes to invest in venture capital.
