Whirlwind Substation. 1. Install a dedicated double breaker 220 kV line position to terminate the new Aura-Whirlwind 220 kV Transmission Line which will include:
Whirlwind Substation. The Participating TO shall install the Whirlwind 2nd and 3rd (3AA and 4AA) transformer banks.
Whirlwind Substation. The supporting infrastructure at Whirlwind Substation, specified in the AV Solar Ranch One LGIA, which has already been installed, for the termination of the Solar Ranch – Whirlwind 220 kV Transmission Line. A relay coordination study and re-set/test of protection relays will be performed, as required, to account for the new Small Generating Facility tap connection.
Whirlwind Substation. Line Drop
Whirlwind Substation a. Equip one 220kV position at Whirlwind Substation to terminate the Avalon Hybrid – Whirlwind 220kV Transmission Line. Install the following equipment at the 220kV Switchyard:
Whirlwind Substation a. Utilize the 220 kV switchrack position to terminate the Desert Star- Whirlwind 220 kV Transmission Line. This work includes: one (1) 220 kV dead-end substation structure, three (3) 220 kV coupling capacitor voltage transformers with steel pedestal support structures, and three (3) 220 kV line tie-downs (Note: subject to detailed engineering, this position may be ultimately shared with a 500/200 kV transformer bank).
Whirlwind Substation. Perform a relay coordination study and re-set/test of protection relays, as required, to account for the new Large Generating Facility interconnection.
Whirlwind Substation. Utilize the Network Upgrades portion of the 220 kV position at Whirlwind Substation, as specified in the TOT573 (Q746) LGIA, to terminate the Xxxxxxx West Project generation tie-line with the following Network Upgrades: i. Two (2) 3000A – 63 kA 220 kV circuit breakers ii. Four (4) 3000A – 80 kA horizontal – mounted group-operated disconnect switches iii. One (1) grounding switch attachment iv. Two (2)-1590 KCMIL ACSR conductors as required
Whirlwind Substation. At Whirlwind install two (2) G.E. N60 logic processing relays or equivalent successor to send additional tripping signals to the generation project.
Whirlwind Substation. Equip one (1) 220 kV position at Whirlwind Substation to terminate the Desert Flower-Whirlwind 220kV Transmission Line with the following Network Upgrades (plan of service): Two (2) 3000A – 63 kA 220 kV circuit breakers Four (4) 3000A – 80 kA horizontal–mounted group-operated disconnect switches One (1) grounding switch attachment 2-1590 KCMIL ACSR conductors as required Two (2) G.E. C60 breaker management relays (breaker failure)
