Dynamic Resilience Return (DRR) answers a better question: How much robust value does this project generate across plausible futures, and how does it improve the resilience of the whole portfolio?
DRR prioritizes projects that add anti‑fragility to the enterprise: they earn well across scenarios, lower drawdowns when things break, and reduce dependency on any single risk driver.
Outcome: fewer write‑downs, stronger cashflow convexity, faster capital cycles.Tip: Ω increases with multi‑market optionality, modular capex, and switchable inputs. ρ* drops with natural hedges and counter‑cyclical cashflows.
Project | E[R] (€m) | σeff | Ω | ρ* | DRR | Decision |

Battery + Trading | 130 | 0.22 | 1.6 | 0.78 | — | — |
Wind (merchant) | 160 | 0.30 | 1.2 | 0.95 | — | — |

No. Sharpe ignores portfolio correlation and real‑option resilience. DRR multiplies scenario‑robustness (Ω) and marginal correlation (ρ*) on top of a scenario‑weighted value/volatility core.
Use DRR as the primary capital ranking. Keep NPV for accounting and debt sizing. If DRR and NPV conflict, resilience risk is likely mispriced—investigate.
Define a rubric (fuel/market switchability, modularity, ramp agility, regulatory adaptability). Calibrate with back‑tests and stress events.
Natural hedges (counter‑cyclical revenues), geography/market diversification, flexible dispatch, and contracts that decouple from existing risk factors.
