Evaluation of capacity expansion scenarios for the Hellenic electric sector
Επιτομή
During the last years, fossil fuels covered the largest share of the produced electricity of the Greek electric sector. In the near term, many units’ decommissioning is expected, a fact that provides the landscape for more investments in gas fired plants and renewable energy resources. The present study analyzes the current state of the Greek energy system, focusing on the historical evolution of electricity consumption and electricity generation. Next, scenarios of future power system expansion that differ in the composition of power generation are examined. The scenarios are compared to the baseline scenario of the 10-year transmission system development plan issued by Independent Power Transmission Operator (IPTO) SA. The objective is to examine the impact of various power generation technologies on the capacity expansion costs and the emission of environmental pollutants and to provide a detailed study for interested parties concerning the expected benefits and limitations of increased penetration of various sources on the power system. © 2021 Elsevier Inc.
