Base Power, an Austin-based energy startup, has secured $200 million in a Series B funding round. This funding marks a turning point in the company’s journey to reshape how households consume and store electricity. Founded in 2023 by Zach Dell and Justin Lopas, Base Power offers homeowners an alternative to outdated and unreliable power systems. The company focuses on solving two urgent challenges: grid instability and increasing electricity costs.
The startup provides a new kind of home energy service—one that doesn’t depend on solar panels or utility grid reliability. Instead, Base Power installs large-capacity batteries in homes, allowing customers to receive continuous, affordable electricity even during blackouts or peak pricing hours. With its latest funding, the company plans to grow beyond Texas and build a vertically integrated manufacturing facility, positioning itself as a key player in the national energy transition.
Offering a Smarter Home Energy Solution
Base Power designs its battery systems to work independently of solar infrastructure. Homeowners choose from two options: a 25 kilowatt-hour or 50 kilowatt-hour backup battery system. These units provide seamless power during outages and contribute to grid support during times of high demand.
To access the system, customers pay a one-time installation fee, typically between $595 and $995, and sign up for a three-year energy service agreement. The contract includes energy delivery, battery maintenance, and monitoring. This model removes complexity from the process and allows customers to enjoy reliable electricity at competitive rates without the burden of ownership or long-term maintenance.
Instead of requiring customers to install solar panels or purchase expensive battery hardware, Base Power assumes responsibility for installation and performance. The company integrates the battery systems with its own energy retail service, providing end-to-end electricity delivery.
This approach allows Base Power to operate as a licensed energy provider in Texas, one of the most competitive deregulated electricity markets in the United States. The combination of hardware, software, and service gives the company an edge over both traditional utilities and solar-battery providers.
Scaling Up with Strategic Partnerships
Since launching operations, Base Power has expanded rapidly across Texas. The company formed critical partnerships with homebuilder Lennar and Bandera Electric Cooperative to bring its battery services to more households. These collaborations accelerated adoption across major Texas markets, including Dallas-Fort Worth, Houston, and Austin.
In March alone, Base Power installed over 10 megawatt-hours of energy storage across customer homes. The company expects to deploy 100 megawatt-hours of battery storage by summer 2025. This pace of deployment reflects both market demand and the operational efficiency of Base Power’s model.
By aligning with major homebuilders, Base Power embeds its systems directly into new residential construction projects. This strategy simplifies customer acquisition and ensures that the batteries function as core components of the homes’ energy systems, not aftermarket add-ons.
Fueling Expansion and Manufacturing with New Capital
The $200 million raised in the Series B round will fund Base Power’s nationwide expansion. The company plans to enter new markets across the U.S., focusing first on states with deregulated electricity markets and high demand for backup power.
A significant portion of the funding will also support the construction of Base Power’s first manufacturing facility in Texas. This factory will produce key components such as battery modules, power electronics, and interconnection hardware. By bringing production in-house, the company intends to lower costs, speed up installation timelines, and reduce reliance on external suppliers.
Base Power’s vertically integrated model will help it scale efficiently while maintaining high quality standards. Manufacturing its own hardware will also allow the company to tailor products specifically for residential applications, a segment often overlooked by large industrial battery manufacturers.
