Ambrosia Energy Building 10-GWh Battery Factory in Texas for Off-Grid Data Centers

Austin Factory to Drive Battery Production Surge

Ambrosia Energy has begun construction on a 10 gigawatt-hour battery manufacturing facility near Austin, Texas, co-founder and CEO Ben Longmier announced at TechCrunch Disrupt in San Francisco. The 150,000-square-foot factory will enable the company to produce approximately 300 megawatts of power generation capacity annually at its field sites, with full production expected within two to three years. This major infrastructure investment represents Ambrosia's commitment to scaling renewable energy solutions for hyperscale data center operators seeking alternatives to traditional fossil fuel power generation.

Solar-Plus-Battery Model Targets Cost Parity With Natural Gas

Ambrosia emerged from stealth in June with an ambitious value proposition: delivering renewable power plants for data centers at $100 per megawatt-hour. The company's core strategy pairs solar panels with battery storage, allowing panels to power data center loads during daylight hours while simultaneously charging battery systems. At night and during cloudy conditions, batteries discharge to maintain continuous 24/7 operations without grid dependence. Longmier and co-founder Sara Spangelo determined this hybrid renewable approach represented the most cost-effective and rapidly deployable option available. The pricing target positions Ambrosia competitively against natural gas turbines that major cloud providers are increasingly planning to deploy for their facility power needs.

First Commercial Plant Breaks Ground This Year

The company is launching its initial commercial power plant in West Texas later this year, pairing 300 megawatts of solar capacity with 660 megawatt-hours of battery storage to deliver 30 megawatts of continuous power output. Ambrosia targets 99.3% uptime reliability—a critical requirement for data center operators who face severe financial penalties for service interruptions. A pilot-scale facility has already demonstrated viability, operating continuously for over 100 days while generating 200 kilowatts of electricity round-the-clock. This real-world operational data validates the company's technical approach before scaling to larger commercial deployments.

Manufacturing Innovation Cuts Component Costs Dramatically

Achieving profitability at $100 per megawatt-hour required significant engineering optimization. Ambrosia simplified component designs across solar mounting systems and battery packs, systematically reducing part counts to lower manufacturing complexity and costs. Rather than purchasing pre-assembled battery packs from external suppliers, the company manufactures battery packs in-house, achieving a parts-reduction advantage of approximately 100x compared to competitors. This vertical integration allows Ambrosia to produce battery packs at roughly 1.3x the cost of raw battery cells, compared to the industry standard of 5-7x for stationary storage systems. By controlling the supply chain and eliminating unnecessary components, Ambrosia has cracked the cost equation that previously made renewable-powered data centers economically unviable at scale.

Founders' Track Record Signals Execution Capability

Longmier and Spangelo previously founded and sold Swarm, a satellite constellation company, to SpaceX, demonstrating their ability to build and execute on advanced technology businesses. Their combined expertise in hardware manufacturing, systems engineering, and scaling production provides credibility for delivering on Ambrosia's ambitious factory buildout and commercial deployment timeline. The duo's prior exit success also suggests access to capital and strategic relationships necessary to rapidly scale battery production and secure long-term contracts with major data center operators.
