Decision

What the current evidence supports

Agent-assisted assessment · independently reviewed · 2026-10-01

Treat Kemmerer as an active development project for long-term power planning.

Why
Construction and regulatory design findings are substantial, but electricity production remains ahead and the EPC arrangement is changing.
Next
Track replacement EPC contracting, fuel delivery, operating licensing and integrated commissioning before relying on output.

Constraints

Blockers

  • Replacement EPC contracting introduces execution uncertainty.
  • Operating authorization and integrated commissioning remain ahead.
  • Electricity output and storage performance remain undemonstrated.
  • Fuel delivery, final costs and completion schedule require confirmation.
