Fuel cell plant-a proposed analysis for economical feasibility of implantation

When we settle a distributed generation in distribution systems, the other segments above the "injection point" notice this installation as a load reduction, relieving all to the demand requested by this system. The implementation of the distributed generation justifies itself when its implementation cost goes smaller or equal at the cost avoided in the installation point, both expressed in US$/kW or US$/MWh. Such evaluation can be translated correctly with the aid of the long term marginal costs. The present paper presents a methodology to allow accomplishment of an analysis of the economical feasibility of the implementation of fuel cell plants. The paper presents practical applications for an important Brazilian utility.
