1- Why Zafarana?

2- Zafarana On-land & Future Projects.

3- Availability and capacity factor in Zafarana.

4- Routine and Predictive Maintenance.

5- Dust Contamination and Blades cleaning.

6- Projects in near future.

7- Other plan for Zafarana.

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.

In 2003, a detailed Wind Atlas of Suez Gulf area

which includes accurate wind data over period

from 1991 – 2001 for ( 10 ) sites was finalized by

cooperation with RISǾ

Zafarana site location

In the south east of Cairo by

190 km

Zafarana site features:-

* Average wind speed ( 9.5 ) m/s * Flat area * Low turbulence * High capacity factor

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.
