Byron-Bethany Irrigation District 69 kV Substation Project

​

WAVE Engineers provided design and construction management services for the new 69 kV substation which included new optical ground overhead power wire, wood power poles, a three-phase manual disconnect switch, three (3) 69 kV current and potential transformers, three (3) single-phase 69 kV fuses, a 12.47 kV to 69 kV power transformer with primary arresters, secondary arresters, oil level alarm, oil temperature alarm and over-pressure alarm, two (2) 15 kV reclosers, three (3) 12 kV potential transformers, 15 kV disconnect switch, and a single-phase pole mounted distribution transformer.

​

The Substation receives power at 69 kilovolts from Western Area Power Administration (WAPA) by-way-of a 2100 feet wood pole transmission line and steps the voltage down to 12.47 kilovolts for system distribution by Byron-Bethany Irrigation District.

The 69kV Substation is a critical element in the operation of the BBID facilities. Loss of available power could result in disruption of water delivery.  In the event of a substation outage it is important to ascertain the cause of the outage, repair the condition, and restore power as quickly as practical.  The BBID SCADA system is interconnected to the substation by radio communications to provide active alarms conditions and operational information; such as, analog values for Kilowatts, Kilovars, Kilovolt-Amps, Kilowatt-Hours, Percent Power Factor, Kilovolts, Amps, and Frequency.
