Egypt enjoys excellent wind
regimes, particularly in the Suez
Gulf where the average wind
speed reaches 10.5 m/sec.
The wind energy resource is
available in large regions on the
Nile banks in the Eastern and
Western Deserts and parts of Sinai.

Power Management & Grid Connection.
Generation Voltage is 690 VAC.
The voltage is stepped up to 22KV by local transformer
in each Turbine.
Power Factor and Grid frequency are kept synchronized with the
grid by each unit.
Lines are connected to Zafarana Substation by under ground Power
cables.
The voltage is stepped up to 220KV in the substation which is by
sequence linked through El-Sukhna Substation by overhead lines.

Future works and expansions
National Strategy up to 2020
•In February 2008, the Supreme Council of Energy approved an
ambitious plan to:
Satisfy 20% of the generated electricity by
renewable energies by 2020, including 12% from
wind energy,
i.e., reaching more than 7200 MW grid-connected
wind farms.
