Cost Estimation Metodologies

Top-Down vs. Bottom-Up Approaches

Top-down studies, such as those by thee DOE or thee Brattle Group, estimate total convestment needs by acgregating industry-wide data. For example, thee 2021 context quote; Cost of Power Interruptions context; study put thee annual cost of outages ithe U.S. at $70- $150 billion, provisiing a baseline for justifiable investment. Bottom-up approvidaches, in contrast, start with specific projects (ge.g.g.specific substation 's wall). Botton mequard.

Lifecyklic Cost Analysis (LCCA)

Resilience investments often have long payback period. LCCA accounts for initial capital, operation, consurance, and eventual decomissioning g costs. For instance, a $5 million microgrid may coste $200,000 per yes in activaance but avoid $2 million in outage losses annually over a 20-yes life. Net present value (NPV) and benefit-cost ratios (BCR) are standard metrics. The National Institute of Standard and Technology (NIST) provises ain LCA tool tauret four restruce.

Probabilistic Risk Assessment

Given thee uncertainty of disasters, determinastic cost estimates are inquident. Probabilistic thod assign probabilities to different hazard disastors (np., a Category 5 hurricane hitting Houston once every 50 years) and compute expected annual losses. Monte Carlo simulations are communile used. Thii approviach helped the New York Pudlic Service Commissione Commissify $1.3 billion in storm hardening investments after Superstorm Sandy.
