UDS designed the new feeder exits from the substation – including 2 new manholes, associated cable and station risers. To accommodate the new feeder configuration, UDS designed the conversion of the surrounding facilities from 8kV to 24.9kV. In addition, UDS worked with two clients to co-locate distribution facilities both on and underneath the towers, so that a corridor could be shared between the companies.
Fairmount Santrol’s Wedron, IL silica sand mining and preparation facilities were rapidly expanding, requiring a new 10/14 MVA, 34.5-12.47kV distribution substation. Short deadlines required a quick turnaround on the substation design and procurement of materials. Utility Design Services was retained to design the substation and provide procurement services. At the request of the client, UDS purchased the substation equipment directly, providing Fairmount Santrol with a single point of contact for all the major material purchases.
UDS served as the interface for coordination of the physical location of the new 34.5kV tap point, metering requirements, protective device coordination, and joint pole use.
The expansion projects at Fairmount Santrol, including the new substation, required a rebuild of 34.5kV line servicing the mine facilities. As part of the mine’s expansion, a portion of the line on mine property had to be relocated. UDS provided engineering and construction staking services for the line on mine property and an additional five miles of the 34.5kV line serving the mine.

Utility Design Services was retained by a large utility company in Illinois to provide field engineering to rebuild, re-span and line harden approximately 10 miles of existing 34.5kV line. Wood poles were replaced with composite poles due to the fact this project was located on various terrains including timber and strip mines.
Construction coordination between Ameren, IDOT, local cooperatives, governments and municipalities
An Illinois municipality had recently completed construction of an addition to their sports complex and needed assistance with lighting design and construction bidding. Utility Design Services was retained to design the lighting layout and power distribution for two football/soccer fields, four baseball/softball fields and the roadway and sidewalk inside the complex.
UDS provided a complete bid package for the municipal’s use in obtaining competitive bids. UDS coordinated the extension of the utility three phase primary underground circuit (12.47kV) into the sports complex property and worked with utility representatives to develop the most economical method of providing a new service to the sports fields. Multiple lighting system manufacturers were consulted to produce bid documents that would provide the Village with a lighting system to meet their needs, and not exceed budgets.
An Illinois municipal client was preparing to relocate a major highway leading into the city. In order to accommodate this need, the municipal would need to remove and relocate approximately 2 miles of overhead line. Utility Design Services was retained to provide the design and layout of the new electrical sub-transmission and distribution lines that would serve the city.
UDS provided construction drawings utilizing PLS-CADD design and the necessary electrical standards and specifications. We provided the required field engineering, design survey and construction staking along the major highway. This project required coordination and permits with the Department of Transportation and the municipal. UDS also provided the procurement of 30 self-weathering steel poles for this project. The project was completed on time and under budget.
Utility Design Services was retained for the addition of a new 69kV line terminal, addition of a bus main breaker, replacement of the protection and control system, and replacement of the existing 69kV circuit breaker.
UDS provided a complete design package for the protection and control systems, as well as the physical layout and design of the new line terminal and 69kV bus breaker. UDS will also provide commissioning assistance, relay testing and in-service operational checkout of the protection system.
Utility Design Services was retained to design the replacement of a 138kV circuit switcher and all protection and SCADA control systems at the station.
The switch station sectionalizes and taps a 138kV transmission line to supply a 138kV line to a coal mine substation. It was desired to retrofit the existing outdoor control panel enclosure with a new pre-wired panel front to minimize cost and outage length. UDS made field investigations and took measurements to develop a custom fit relay panel to bolt directly into the existing outdoor enclosure. The single panel includes two SEL 311C relays to provide line protection and SCADA control of the circuit switchers. An SEL-3530 RTAC serves as the SCADA communications hub. A GPS satellite clock was utilized to maintain high accuracy time for sequence-of-event recording. Relays are connected to the RTAC via fiber optic communications.
UDS provided complete control panel design, including bill of materials, panel wiring diagrams, one-line diagram, three-line diagrams and schematics; as well as foundation design for the new circuit switcher.
