Ambrosia Energy will build a 10 GWh factory in Texas to make batteries for off-grid data centers
At a TechCrunch Disrupt keynote, Ambrosia’s CEO Ben Longmier announced that the new plant near Austin will churn out enough battery capacity to support roughly a 300‑megawatt power plant each year. The facility, sized at 150,000 sq ft, targets full‑scale output within two to three years and will assemble its own packs from commercially sourced cells, cutting component counts by about two orders of magnitude compared with conventional stationary storage solutions. By keeping the bill‑of‑materials close to 1.3 times the raw cell price—far lower than the typical 5‑7 times multiplier—the company claims it can deliver electricity at $100 per megawatt‑hour, a price point that rivals natural‑gas turbine generation currently favored by large cloud providers.
The venture slots into a rapidly evolving market where hyperscale operators are seeking reliable, carbon‑free alternatives to diesel or gas‑fired peaker plants. Ambrosia’s first commercial site, slated for West Texas later this year, will pair 300 MW of photovoltaic arrays with 660 MWh of storage to provide a steady 30 MW output and 99.3 % availability. This “over‑built” configuration—excess solar capacity plus ample battery reserve—mirrors a broader industry shift toward renewable micro‑grids that can guarantee uptime without fuel logistics. The founders’ background in satellite constellations (Swarm, sold to SpaceX) underscores a pattern of leveraging high‑volume, low‑cost manufacturing to disrupt entrenched infrastructure markets, a play also seen in firms like Tesla’s Megapack and emerging lithium‑iron‑phosphate pack makers.
The success of Ambrosia hinges on whether its aggressive cost engineering scales beyond pilot modules. The 200‑kW test unit has run continuously for more than 100 days, but moving to multi‑hundred‑megawatt deployments will test supply chain resilience, thermal management, and regulatory approvals for grid‑interconnection. Moreover, the $100/MWh claim assumes stable raw‑cell prices and minimal margin erosion as production ramps. Investors and data‑center operators will watch the West Texas rollout for real‑world performance metrics, especially the ability to meet the promised 99.3 % uptime under variable weather and load conditions. Competition from established storage OEMs, as well as potential policy shifts around renewable incentives, could also influence the economic calculus.
Key Takeaways
Ambrosia’s Texas factory is designed to produce 10 GWh of battery packs, enough for a 300 MW power plant each year, within a three‑year build‑out.
The company’s in‑house pack assembly reduces part count dramatically, driving battery costs to roughly 1.3 times the cell price.
Its first commercial solar‑plus‑storage plant aims to deliver continuous 30 MW power with 99.3 % uptime at a target price of $100 per MWh, directly challenging natural‑gas turbines.
The upcoming West Texas deployment will be the first real‑world test of whether Ambrosia can sustain its cost and reliability promises at scale.
