Rezumat: In sectorul energiei, demersul internalizarii presupune integrarea in costul energiei a valorii daunelor produse mediului natural prin producerea, transportul, distributia si consumul energiei. Internalizarea externalitatilor se traduce prin plata sub forma taxelor sau amenzilor acordate producatorilor de externalitati negative pentru pagubele sau daunele produse asupra mediului si sanatatii umane astfel incat costurile private sa ajunga la nivelul costurilor sociale. In aceasta lucrare s-a determinat nivelul optim al taxelor si amenzilor ce trebuie impus pentru a se atinge optimul social, deoarece prin rentabilitatea unui sistem termoenergetic se intelege capacitatea sistemului termoenergetic de a obtine profit, adica de a fi rentabil, de a nu inregistra pierderi care sa il aduca in starea de faliment. S-a realizat o aplicatie in programul de calcul Matlab – Simulink cu ajutorul careia impunand taxele pe emisiile de poluanti se determina valoarea taxelor platite suplimentar in cazul depasirii valorilor limita de emisie (VLE) legale sau impunand aceste taxe suplimentare se determina valoarea taxelor pe emisiile de poluanti aplicate in cazul incadrarii emisiilor in VLE legale.

Abstract: In the power system, the approach to the internalization supposes the integration in the energy cost of the value of the damage caused to the environment by the production process, by the transport, distribution and consumption of energy. The internalization of the externalities is translated by the payment of taxes or fines by those who cause damage to the environment and to human health in such a way that private costs may reach the level of social costs. In the present paper there has been determined the optimum level of the taxes and fines that have to be required in order to reach the social optimum, as by means of the profitableness of a thermo-power system one understands the capacity of the thermo-power system to obtain profit, that is to be lucrative, not to record losses that could lead it to bankruptcy. There has been made an application in the Matlab-Simulink programming language and with its help imposing the taxes on the pollutants emissions there can be determined the value of the supplementary taxes in case the legal limit values are exceeded or by imposing these supplementary taxes there is determined the value of the taxes on the applied pollutant emissions in the case of the legal limit values.
