Alexander Substation Redesign
The Lane-Scott Electric substation located near Alexander, KS underwent a major redesign to relocate the transformer and increase operability. Construction was finished and the substation was powered back up this past December.
The project was initiated the summer of 2016 when straight line winds knocked down several 34.5kv structures on both circuits of the Alexander substation. The simultaneous faults caused the 115/34 transformer to fail. The transformer lines were repaired to restore power but was now operating the system at a diminished capacity with limited capabilities. In addition, the substation was very small. Vehicles could barely fit inside the fence for service or repairs, and most often the fence had to be let down. The power transformer was also located directly beneath the incoming 115kv transmission line.
To help resolve the issues, Sunflower Electric was commissioned to conduct a study to analyze our options. The conclusion was the substation needed a larger transformer, which would greatly improve operational capabilities. To facilitate additional space, a gas line had to be relocated and additional ground purchased from the landowner. The station was removed from service the summer of 2018 and construction began. Sunflower Electric crews, Lane-Scott Electric, and sub-contractors completed the work by late fall. Testing and outage preparations were completed, and the station returned to service.
The improved station will provide our members with increased capacity and reliability for many years. It also strengthens our operational capabilities, allowing us to back-feed areas and take other stations out of service for maintenance and repairs.
