Episode notes
INSIGHT

Modular On‑Site Gas Is The Fast Path

  • On-site gas power is scaling rapidly via modular turbines and reciprocating engines to meet AI data-center urgency.
  • These smaller, factory-made units shorten lead times compared with large CCGTs and enable fast deployment.
INSIGHT

Gas Replaces Diesel Spending

  • On-site gas installations are cannibalizing diesel generator spend by serving first as primary then as backup power.
  • Data centers shift dollars from diesel to gas because turbines serve dual roles as onsite power and later backup.
ADVICE

Forecast CapEx From Pre‑Leasing Signals

  • Use on-the-ground indicators like construction starts and pre-leasing to forecast hyperscaler CapEx.
  • Track data-center model signals because they provide near-term visibility into next-year CapEx commitments.
