The paper investigates the effect of the carbon tax on the optimal parameters and indicators of two coal power plants: a steam turbine power unit with coal dust burning in a steam boiler and an internal gasification combined cycle power plant.

Throughout the entire range of carbon tax values, IGCC power plant has the best economic and environmental indicators.
