What the current evidence supports

Human editorial judgment · 2026-09-22

Adopt with guardrails

Why
Most mature next-gen geothermal asset: real non-recourse debt ($421M), fully contracted offtake (SCE/Shell), record drilling-cost reductions (70% YoY) and flow triple Project Red; Q1 2026 results show all Phase I wells complete and a GeoBlock at mechanical completion — but headline productivity rests on a single test and grid power is not yet flowing
Next
Track Phase I first-power (Q4 2026 COD) and the ramp via GeoBlocks 2-3 (Q1 2027) as the proof point before treating 500 MW scale-up as bankable; verify sustained multi-well flow vs single-test figures and the new Gen 3.0 lateral performance
