Author ProfileAbstract
The ambitious Algerian program for diversification of electric energy
sources is targeting 22 000 MWe from the renewable energy to the horizon
of 2030. This study is a thermo-economic assessment of an integrated
solar combined cycle system installed in the Saharan region, which
during the nights or cloudy days works as a conventional combined cycle
and does not need storage or back-up systems. The obtained results show,
in one side that the solar electricity ratio may reach about 17 % and
the global thermal efficiency up to 63 %, leading to lower fuel
consumption and carbon emission. In the other side, the economic
assessment depicts that the levelized cost of energy may reach a value
of 0.0222 $/kWh which is about 28 % higher than CC plants. By
considering the environment this latter is even more and may reach about
0.0272 $/kWh, but the annual solar contribution, relatively to that
installation site, allows about 18.45 million $ of fuel saving and
avoidance of 0.89 million ton of CO2 emission over 30 years of
operation. operation.
