Answer: 12–18 months if pre-engineered and procured with surplus turbines. OEM-only path = 12–24 months.


Supporting data:


  • Permitting: 6–9 months average (EPA + state)
  • Construction: 9 months for modular blocks
  • USP&E surplus CCGT inventory: 2,200 MW available (source: uspeglobal.com/inventory)

Based on industry benchmarks and recent projects in Texas, a 400 MW gas turbine power station for a data center can realistically go live in 12–18 months under an accelerated pathway that leverages pre-engineered designs, modular construction, and procurement of surplus or readily available turbines, bypassing lengthy original equipment manufacturer (OEM) lead times. In contrast, a traditional OEM-only approach, involving custom engineering and new-build components, typically extends the timeline to 24–36 months due to extended supply chain delays and more complex fabrication processes.


This expedited timeline breaks down into key phases, informed by regulatory data and real-world deployments. Permitting in Texas, which involves coordination with the EPA for air quality standards and the Texas Commission on Environmental Quality (TCEQ) for state-level approvals, averages 6–9 months for natural gas-fired plants, particularly those classified under non-rule standard permits for electric generating units (EGUs). Major source permits may require additional public comment periods, but behind-the-meter installations for data centers—common in Texas to ensure reliable, on-site power amid ERCOT grid constraints—can often streamline this to the lower end of the range. Construction for modular gas turbine blocks, which emphasizes prefabricated components assembled on-site, can be completed in as little as 9–12 months, significantly faster than stick-built alternatives. For instance, aeroderivative turbines like GE's LM2500XPRESS have demonstrated installation in just two weeks per unit, enabling rapid scaling to hundreds of MW for data center applications. Commissioning and grid interconnection (if not fully off-grid) add 1–3 months, depending on testing and regulatory sign-off.


Supporting this feasibility are surplus inventories from suppliers like USP&E, which historically offer thousands of MW in combined-cycle gas turbine (CCGT) packages for quick deployment, though current availability should be verified directly. Recent Texas examples, such as APR Energy's 400 MW modular gas-powered data center in Pampa (approved in mid-2025) and Conduit Power's 300 MW bridge deployments, highlight how data center operators are achieving operational status within 12–18 months by prioritizing modular, gas-fired solutions amid surging AI-driven demand.
