breos.economics.calculate_lcoe_from_projection(cost_projection, total_investment=None, discount_rate=0.0, production_column='PV_Production_kWh')[source]#

Calculate LCOE from a simulated multi-year projection.

This variant is intended for simulation outputs that already contain year-by-year PV production and replacement costs. It uses system CAPEX, operation costs, and replacement costs as the cost basis; grid import charges, fixed grid charges, and export revenue are excluded because those are tariff outcomes rather than generation costs.

Parameters:

  • cost_projection (DataFrame) – DataFrame from cost_analysis_projection().

  • total_investment (Optional[float]) – System CAPEX. If omitted, uses cost_projection.attrs["total_investment"] or infers it from the first cumulative/annual system-cost row.

  • discount_rate (float) – Discount rate used for production and annual costs.

  • production_column (str) – Column containing yearly production in kWh.

Return type:

float

Returns:

LCOE in €/kWh.
