Today, model checking techniques and corresponding tools are widely applied in diverse case driven scenarios, the safety critical ones in particular. Addressing current situation in Ukraine, an energy domain is among the topical spheres, where safety critical business processes take place. To foster the functional safety of corresponding program-algorithmic solutions, the model checking techniques and related tools are applied to the formal specifications of named solutions. Doing so is not a trivial task: it depends on a particular use case scenario determining the architecture (structure and couplings) of the resulting design artifact. Moreover, the outcomes of formal techniques and tools application directly depend on specification atomicity level chosen – as a tradeoff between the complexity of program- algorithmic constituent addressed to be represented in formal specification and available computational and spatial resources of the computing platform with model checking technique implementation – because of an exponential growth of transition system state space. To this end, to foster the effectiveness of model checking technique application, with respect to a particular case driven scenario, the analysis of broadly applied TLC model checker has been conducted on the basis of a role model from energy domain. Experimentation has been conducted by addressing two alternative implementations of the TLC method. Both – computational and spatial properties – have been covered. To estimate also the domain related spatial expenses on verification, with respect to the number of software threads utilized, the approximation task has been resolved.
