The Effect of Regionally Integrated Energy Systems on CO2 Emissions Reduction and Wind Integration: the Case of South East Europe

Regionally integrated energy systems can have significant benefits for countries which need extensive replacement and rehabilitations of the existing installations, have small energy markets and energy intensive economy. This paper examines benefits from integration of high share of intermittent renewable energy sources (RES) into energy system of the South East Europe (SEE). The energy system of the SEE is analysed on the basis of two scenarios in the EnergyPLAN model. First scenario is the “national scenario” which analyses benefits from RES integration into national energy systems of SEE countries. Second scenario is the “Integrated scenario” which analyses integration of intermittent renewable energy sources into regionally integrated energy system of the SEE. Total installed capacity of intermittent RES and its impact on the CO2 emission reduction in both scenarios are determinate by taking into account economic limits for critical excess of electricity. The main findings are that total installed capacity of fluctuating RES and CO2 emissions can be significantly increased in the SEE through integration of energy systems.
