Objective The goal of this article is to describe a conceptualization case study in the power supply sector, in which around 1,200 technical engineering terms were extracted to build an ontology. Methodology: For this purpose, we here first delimit the theoretical framework, then present the context of the project, in addition to list the set of candidate terms. We also describe some of knowledge acquisition techniques, as well as discuss techniques for defining terms and deriving categories. Results: Our research resulted in the record of techniques applied to the candidate terms, in the understanding of the domain peculiarities and, as far as possible in a case study, in obtaining experience and good practices to be applied in similar domains in strategic areas of society. Conclusions: it is clear the need for a methodology for building ontologies aimed at Information Science professionals, which includes the conceptualization phase.
