Rezumat:

Cogenerarea de mica putere este o solutie interesanta pentru problema dezvoltarii retelelor de alimentare cu energie electrica. Scopul acestei lucrari este de a prezenta o metoda mai rapida pentru estimarea oportunitatii economice a proiectelor de cogenerare de mica putere considerand si subventiile. Criteriul „Venit Net Actualizat” este folosit pentru evaluarea financiara a proiectelor. Se compara solutia de cogenerare cu varianta clasica: cumpararea energiei electrice din retea si producerea locala a caldurii. Reducerea emisiilor de CO2 joaca un rol cheie in gasirea unei cai de dezvoltare a cogenerarii de mica putere. In lucrare sunt prezentate rezultatele aplicarii metodei propuse pentru conditii specifice diferitelor tari din UE. The small-scale cogeneration is an interesting solution for the problem of the electric grid development. The aim of this paper is to present a faster method for estimating the economical opportunity of a small-scale cogeneration project by taking into account the subsidies. The payback period criterion is used for financial evaluation. It compares the cogeneration solution with the classical one: electricity from the grid and local heat production in a boiler. The CO2 emissions reduction plays the key role for finding a way for small-scale plants development. There are presented the results of the method application for different EU countries conditions.
