Ambrosia Energy Breaks Ground on Texas Battery Facility

The company, founded by former Swarm executives Ben Longmier and Sara Spangelo, intends to deliver continuous power at a target cost of $100 per megawatt-hour. By simplifying component architecture—specifically solar mounts and in-house battery packs—the firm claims to have reduced part counts by a factor of 100 compared to industry competitors. This manufacturing efficiency allows the company to reach costs roughly 1.3 times that of a bare battery cell, significantly lower than the 5x to 7x multiplier typical for stationary storage systems.

Ambrosia’s first commercial power plant is scheduled to begin construction in West Texas later this year. The facility will integrate 300 megawatts of solar capacity with 660 megawatt-hours of battery storage to provide 30 megawatts of steady power. The startup reports that its pilot-scale system has already maintained continuous operation for over 100 days, demonstrating a path toward the 99.3% uptime requirement necessary to serve high-demand data center clients.
