The unmanned aircraft systems program on Kansas State University’s Polytechnic Campus is working with industry partner Westar Energy on integrating drone technology into the electric utility sector.
Kansas State University’s Polytechnic Campus and Kansas-based power company Westar Energy are propelling the electric utility industry forward by innovating inspection and maintenance methodologies with drone technology.
With a focus on increasing reliability for customers, improving employee safety and reducing costs, Kansas State Polytechnic’s unmanned aircraft systems program and Westar Energy have been collaborating over the past year to integrate unmanned aircraft into the power company’s services. The partners, whose relationship dates back to 2013, have been working to establish an in-house UAS team at Westar Energy as well as redefine inspection and maintenance techniques using unmanned aircraft — often referred to as drones — for transmission lines, power plant boilers and electrical substations.
“One of our program’s strategic objectives has been to help introduce UAS technology to the commercial market, and we are proud to have Westar Energy as a partner because this collaborative relationship is a win-win for both of our interests,” said Kurt Carraway, executive director of the UAS program on K-State’s Polytechnic Campus. “The opportunity to assist Westar Energy in building an organic UAS program from the ground up has been tremendously rewarding for us — we get to learn about the power industry while helping Westar Energy provide first-class service to its valuable customer base. We look forward to continuing this developmental work.”
Westar Energy has implemented this technology in the day-to-day inspection of thousands of miles of transmission lines and utility towers that run across Kansas. UAS platforms capture imagery of the structures to identify needed replacements and inspect completed repairs. The standard procedure for all power companies has been employees either using binoculars to examine the lines and towers, or riding lifts high into the air —which can be dangerous.

Westar Energy has a team of employees who have completed multirotor and fixed-wing training at Kansas State Polytechnic and lead the power company’s internal UAS division. Together with Kansas State Polytechnic, 3-D mapping of substations and boiler inspections also have been explored. The Kansas State Polytechnic UAS program has assisted Westar Energy’s UAS program with developing and testing protocols, providing additional flight instruction and creating operational guides for these new areas with UAS technology.
“Our UAS program saves money for customers by making our operations more efficient and our work safer. It also makes our service more reliable,” said Jason Klenklen, supervisor of transmission maintenance for Westar Energy. “We can use UAS or drones to identify struggling equipment before it causes an outage. Drones also make it safer and faster to inspect lines in difficult-to-reach areas when crews are locating the cause of a power outage.”
With photogrammetry, Westar Energy can generate authentic images, 3-D maps and drawings with accurate measurements of their substations so maintenance in a specific area can be outlined ahead of time instead of in the field where space can be compact and precarious. Westar Energy employees have been trained how to set up an autonomous flight plan, which is necessary for the camera on the UAS platform to take photos based on either time or distance, as well as how to execute the mission to ensure quality data.
Kansas State Polytechnic and Westar Energy’s most recent exploration has been focused on using unmanned aircraft to inspect boilers. The use of UAS inside a boiler reduces risks to personnel while allowing assessments to be conducted in an efficient and timely manner.
“Incorporating UAS, or drones, into the inspection process of boilers adds an element of safety. It allows employees to view the internal components of the boiler through real time imagery captured by a drone while securely staying on the outside,” said Sam Sharp, a researcher in the Kansas State Polytechnic UAS Laboratory and Westar Energy’s primary liaison. “Because there are no lights inside the boiler and a GPS signal is not accessible, extensive training is needed to control the aircraft. This is one of the most valuable applications of a drone within the energy sector, so the lengthy training is worth it.”
The Smoky Hill UAS Pavilion was built in part by Westar Energy and is housed on the Polytechnic Campus. It measures 300-feet-long by 200-feet-wide and is 50-feet-tall, providing a space for accessible flight training and research.
In October 2015, Westar Energy and Kansas State Polytechnic collaborated on opening one of the largest enclosed unmanned flight facilities in the nation. Built on the Polytechnic Campus, it measures 300-feet-long by 200-feet-wide and 50-feet-tall, and employs 25 wooden poles donated and installed by Westar Energy as well as custom fabricated netting panels on all sides and across the top. The structure, called the Smoky Hill UAS Pavilion, provides a space for accessible flight training and research for students, staff and faculty in addition to outside industries for company instruction and short courses.
Kansas State Polytechnic is recognized as having the No. 2 UAS program in the nation by Drone Training HQ. The program, which began almost 10 years ago, consists of a bachelor’s degree with two focus areas — UAS flight and operations and UAS design and integration — as well as a UAS minor, research and flight operations. Kansas State Polytechnic was the first entity in the United States to be awarded statewide access for unmanned flight operations by the FAA and is a member of the FAA Center of Excellence for Unmanned Aircraft Systems.
Westar Energy provides electricity to about 700,000 homes and businesses in the eastern third of Kansas. In early 2017, Westar will provide about half the electricity needs of its retail customers from emission-free sources.
