Note: The length of the OHTLs shown in the figure above has since been revised and the figure
above is meant to show the interconnectedness between the Dzhankeldy & Bash Projects and
the OHTL associated facilities.
Power generated by the wind farms will be exported to NEGU
via the plant electrical
interconnection facilities/500kV AIS of One and Half Breaker Scheme. Preliminary details of the
Air Insulated Substation (AIS) is shown in the
figure below and in Appendix G.

The 500kV unit bay for the Dzhankeldy and Bash Wind
Farm will comprise of
Circuit breaker;
Isolator;
Earthing;
Switches,
Measuring CTS & amp;
Protection relays
and associated control
Both the AIS for the Dzhankeldy and Bash Wind Farm will be designed for 500kV level and will
employ one and half breaker scheme. It is understood from ACWA Power that the Bash 500kV
pooling switch sub-sta
tion will be operated by both the FE “ACWA Power Dzhankeldy Wind”
LLC and FE “ACWA Power Bash Wind” LLC. To allow independent project implementation, the
AIS at Bash Wind Farm will be equipped with section disconnector that will be connected after
commissioning both Wind Farms.
