Skybox Austin II

Government ReviewMonitorReview in progress — 3 sources cited

Proposed size

30 MW

Building area

148,500 sq ft

Cooling

Closed-loop air-cooled chillers (no evaporative cooling)

Investment

Developer

Skybox Datacenters

Skybox Austin II is a planned 30 MW, 148,500 sq ft data center at 2515 S Kenney Fort Blvd in Pflugerville (Travis County), developed jointly by Skybox Datacenters and Prologis. TDLR building records show a $63 million shell-and-core filing (start Dec 2023, target completion Oct 2024), with an interior fit-out filing of approximately $60 million. Total campus investment is stated at $548 million. The facility uses the same closed-loop air-cooled chiller design as Skybox Austin I.

Water Impact

Daily water use (estimated range)

375 – 54K gal/day

Water returned per day

None reported

Per Skybox closed-loop design (same as Austin I). Developer states less water than 5 households. High estimate from LBNL 9,000 gal/MW/day discounted 80% for closed-loop., based on Skybox has used closed-loop air-cooled chillers exclusively since 2016. Ongoing daily water use negligible.

Estimated daily water use375 – 54K gal/day

vs. 5M gal/day (typical 400 MW facility)

The higher estimate is equivalent to the daily water use of approximately 540 households. San Marcos has approximately 25,000 households.

Water intake
375 – 54K gal/day
Lost to evaporation
100%
Returned to system
0% (None reported)
Water flow: 375 – 54K gal/day enters the facility per day. Approximately 100% (54K gal/day) is lost to evaporative cooling and cannot be recovered. No return flow is reported.
For comparison: A sustainable seawater-cooled data center can return over 95% of water to the system. A typical land-based evaporative cooling tower loses 80–95% to evaporation — the primary method used in Texas.

Direct water figures are estimates from permit applications and developer disclosures. Indirect (power generation) figures are calculated estimates. Actual water use depends on technology choices, operating capacity, and weather conditions.
