Mine Energy Resilience Gap Assessment Template

The Mine Energy Resilience Gap Assessment Template is a structured Excel-based diagnostic tool designed to systematically identify, quantify, and prioritize vulnerabilities and deficiencies in a mine’s energy infrastructure relative to resilience benchmarks—encompassing reliability, redundancy, adaptability, and sustainability under operational, climatic, cyber, and supply-chain stressors.

📖 Overview

This template operationalizes energy resilience as the capacity of a mining operation’s power generation, distribution, storage, and control systems to anticipate, absorb, recover from, and adapt to disruptive events—including grid outages, fuel shortages, extreme weather, equipment failures, and cyber intrusions. It integrates quantitative metrics (e.g., uptime duration, backup runtime, renewable penetration ratio) with qualitative assessments (e.g., maintenance maturity, vendor dependency risk, emergency response protocol completeness) across multiple infrastructure layers: primary supply (grid/diesel/solar/wind), on-site microgrids, energy storage (batteries, flywheels), power electronics (inverters, SCADA), and governance (policies, training, monitoring). The assessment follows a gap-driven methodology: first establishing target resilience criteria aligned with ISO 55000 (asset management), IEC 62443 (cybersecurity), and industry-specific frameworks like ICMM’s Climate Risk Guidance; then scoring current-state performance across defined dimensions (e.g., 'Redundancy', 'Diversity', 'Autonomy'); and finally calculating weighted gap scores to inform prioritized capital and operational interventions. Crucially, it supports scenario-based stress testing—such as simulating 72-hour grid loss or diesel supply chain disruption—to validate system behavior and expose latent interdependencies.

📐 Key Formulas

Resilience Gap Score (RGS)

RGS = Σ[(Target_Score_i − Current_Score_i) × Weight_i]

Quantifies the aggregate deficit across resilience dimensions, normalized to a 0–100 scale where higher values indicate greater intervention urgency.

Energy Autonomy Index (EAI)

EAI = (Renewable_Generation_kWh + Onsite_Storage_kWh) / Total_Energy_Demand_kWh

Measures the proportion of mine energy demand met without external fossil-fuel or grid dependence over a defined operational period.

Critical Load Recovery Time (CLRT)

CLRT = Max{Time_to_Restore_Power_for_Critical_Processes_j}

Identifies the longest duration required to restore power to safety- or production-critical loads (e.g., dewatering, ventilation) following a defined disruption event.
