Paging YC application reviewers. If you're looking at applications related to the energy - here's some frameworks for how to think about the KPIs for energy systems. LCOE – Levelized Cost of Electricity (lifetime cost per kWh generated) VALCOE – Value-Adjusted LCOE (cost adjusted for grid value & timing) EROI – Energy Return on Investment (energy returned vs energy invested) WTW – Well-to-Wheel efficiency (full fuel/energy chain efficiency) LACE – Levelized Avoided Cost of Electricity (revenue it actually earns) System LCOE – Integration costs of variable resources on the grid LCOS – Levelized Cost of Storage (real cost per discharged kWh) LCA/CED – Life Cycle Assessment + Cumulative Energy Demand (full cradle-to-grave energy & material footprint) EPBT – Energy Payback Time (years to recover invested energy) ELCC – Effective Load Carrying Capability (reliable capacity credit) Exergy – Second-Law efficiency (true useful work potential) Grid Stress / Reliability Metrics: LOLE – Loss of Load Expectation (expected shortfall days per year) LOLH – Loss of Load Hours (hours at risk of blackouts) PRM – Planning Reserve Margin (% capacity buffer above peak) N-1 – Contingency Analysis (system survives loss of any single major element)
