Operational Improvements Enhance Service
Twin Springs Substation
Twin Spring Substation:
Located in the southern section of our service territory in Finney County, our new Twin Springs Substation and the transmission line that runs south of Garden City feeding it, have been a long time coming. For many, it achieves a project that’s been twelve years in the making and the cause of many sleepless nights. The transmission line and the subsequent substations allow Lane-Scott and neighboring cooperatives to not only provide more reliable service, but also increase development possibilities previously restricted by low electrical capacity.
Much of the twelve-year project was spent gaining access to a transmission line and securing the land necessary to span such an area. Once the transmission line location was finalized, Lane-Scott faced hurdles involved with securing the location of the substation such as water run-off issues, prairie chicken regulations and landowner concerns. Two years ago, the build of the substation began, and on January 7th of 2020 it was energized!
The need for the substation was apparent to us and all those living in the area. Lane-Scott has limited access to transmission lines in our service territory, especially in the area where the Twin Springs Substation now resides. The load suppling the area came all the way from the Dighton substation, which not only limited the amount of load capacity for members to only a single or double phase line, but the area was affected by interruptions in the line clear to the Dighton substation about 40 miles upstream.
The substation houses two separate voltage transformers each with 10-megawatt capacity, tied with auto transformers. This allows us to more effectively perform maintenance. If one transformer goes down, the second can handle the entire load by itself, eliminating outage time during maintenance events. The equipment’s auto-technology also improves communication with several reclosers, allowing for better interaction and outage detection capabilities. For example, radios are placed in voltage regulators. Before this magical technology was installed, when a customer called with service issues, crews would drive to the substation to check regulators, increasing the time it took to resolve the issue. The new equipment sends notification to our computer system, allowing us to be proactive with outage detection and power quality capabilities.
In addition to the benefit of improved outage detection, the load capacity improvements members will gain are monumental. There will be superior power quality resulting in fewer “blinks” of electricity, while the 3-phase lines will now allow for development opportunities such as irrigation, grain bins and new oil prospects.
Lane-Scott is very excited about this new addition to our system, the advancement opportunities new technology brings and the improved service for our members. As Nate Burns, the Lane-Scott’s Operations Manager said, “There are good things on the horizon for Lane-Scott Electric.”
Jagger Breaker Station
Sunflower Electric decided after conducting an outage study of all their member’s locations, that north of Lane-Scott Electric’s Dighton Substation was their top priority for a breaker station location to better meet their and our member’s needs.
All Lane-Scott’s substations, prior to the addition of the new transmission line feeding Twin Springs, were on Sunflower Electric’s transmission line running from Scott to Ness City. When an outage on the transmission line would occur, every member’s power in our entire service area was knocked-out. Lane-Scott crews would work with Sunflower to sectionalize the line using manual switches located at the Manning, Dighton and Beeler Substations. After opening switches, Sunflower could turn their breakers on in Ness & Scott to energize the remainder portion of the line, isolating the outage area. Lines were then patrolled to find the problem causing the outage, and another manual process of closing switches took place to re-energize the lines. This time-consuming process caused long widespread outages and obvious frustration for members.
The remedy lies in the Breaker Station with automated technology, electronic monitoring and opening of breakers with automatic switches. When a problem on the transmission line now occurs, crews will still drive to one of the substations to sectionalize the line, but only one substation will be down instead of all of them. This eliminates wide-spread system outages and reduces the length to only 30 minutes. Lane-Scott’s service to our members and community is greatly improving with the addition of Twin Springs Substation and Sunflower’s Jagger Breaker Station!
