Levelized Cost of Energy vs Project Lifetime

Levelized Cost of Energy (LCOE)

LCOE is the average cost per unit of energy over the entire lifetime of a generating asset, allowing fair comparison between different energy sources.

Simplified Formula

LCOE = (Capital Cost + Lifetime Operating Costs) / Lifetime Energy Output

A full LCOE includes discounting future costs and energy, but this simplified version gives a useful first approximation. Lower LCOE means cheaper energy.

Example Calculation

A $50,000 solar system produces 10,000 kWh/year with $500/year maintenance over 25 years.

  1. 01Total cost = $50,000 + ($500 x 25) = $62,500
  2. 02Total energy = 10,000 x 25 = 250,000 kWh
  3. 03LCOE = $62,500 / 250,000 = $0.25/kWh
  4. 04That is 25 cents per kWh
