Levelised cost comparison: coal (with carbon tax) vs solar (unit: USD/MWh)
⚠️ Only 2020–2022 historical data is available. The grid-parity crossing will appear once KEI submits projections.
Where coal and solar LCOE cross = grid parity
Grid parity: the point where renewable generation cost equals fossil fuels. Solar LCOE keeps falling with innovation while coal LCOE is expected to rise under carbon pricing; the crossing year is the key indicator in the NetZero scenario.
