Structure a PPA against your actual load

How the numbers are computed

1. Coverage profile factor maps the load profile to the share of consumption a renewable PPA can cover:
   • industrial-flat: 0.72 — flat industrial load is well-matched to wind + solar.
   • 24-7: 0.55 — hour-matched coverage requires storage; lower share.
   • peaky: 0.85 — daytime-weighted load aligns with solar generation.
2. Covered MWh = annual consumption × coverage factor (clamped to plant availability of 0.95).
3. Annual savings = covered MWh × (grid price − PPA price).
4. Tenor savings = annual savings × tenor (undiscounted; for a discounted view, apply your WACC).

// coverage factor by load profile
const COVERAGE = {
  'industrial-flat': 0.72,
  '24-7': 0.55,
  'peaky': 0.85,
};
const covered = consumption * min(COVERAGE[profile], 0.95);
const annualSavings = covered * (gridPrice - ppaPrice);
const tenorSavings = annualSavings * tenor;
