High-Level Assumptions & Limitations
  • Theoretical benchmark only — assumes perfect-foresight arbitrage. Actual dispatch and round-trip efficiency losses are not reflected.
  • Capacity-market and balancing-market revenue layers are excluded from this view.
  • Curtailment risk and project-specific connection costs are not modelled here.
  • The Latest Month tier is a relative rank within the displayed month — not an absolute investment grade.

Project-specific underwriting, sensitivity cases, and source-linked investment memos are delivered through pilot engagements.

Public sample benchmark computed from JEPX 30-min spot data. Annual figures reflect perfect-foresight arbitrage with no efficiency discount.
