Multi-criteria analysis of electricity generation technologies in Lithuania

The paper presents the process of choice of electricity generation technologies, which has been solved using a case of Lithuania's power sector and such multiple criteria mathematical methods as AHP (Analytic Hierarchy Process) and ARAS (Additive Ratio Assessment method). Having considered the impact of environment, a set of evaluation criteria was compiled for electricity generation technologies. Analysis of qualitative and quantitative criteria helped to rate the electricity generation technologies considering their economic, technological, environmental social and political aspects and rank them in order of priority. The derived results show that in case of Lithuania it is viable to consider further development of the nuclear power generation capacity. Among the electricity generation technologies related to renewable energy sources a clear priority is assigned to biomass technologies. Sensitivity analysis performed by applying multi criteria method ARAS, has confirmed this result. (C) 2015 Elsevier Ltd. All rights reserved.
