## Governing Mathematical Formulation & Units
- Formula: `LCOE ($/MWh) = [ Σ_{t=0..N} (CAPEX_t + OPEX_t + Fuel_t) / (1 + r)^t ] / [ Σ_{t=1..N} E_t / (1 + r)^t ], where E_t = Capacity (MW) × 8,760 h × CF × (1 − d)^{t−1}`
- Units: Capacity in MW; CAPEX in $/kW; OPEX in $/kW-yr; discount rate r in %; degradation d in %/yr; annual generation E_t in MWh; LCOE in $/MWh (real price-year currency).

## Reproducible Worked Example
Scenario 1 (Utility Solar PV Cohort, 2027 commissioning, CAPEX = $950/kW, -2%/yr cohort capex trajectory): Discounted lifecycle cost divided by discounted energy ledger yields LCOE = $50.02/MWh for the 2027 cohort, declining to $49.18/MWh (2028), $48.36/MWh (2029), and $47.56/MWh (2030) under identical discount and capacity-factor assumptions.
