Substation Rebuild/Expansion
Northwest Arkansas

Background
In response to continued regional growth, the Electric Cooperative needed to expand and modernize a key substation originally constructed in 1962—based on an Allgeier Martin design. Though multiple additions had been made over the years, portions of the existing drawings were incomplete. The Cooperative brought AMA back to assist with a comprehensive rebuild and expansion of the low-voltage side, including the removal and replacement of station transformers, relocation of the capacitor bank, and addition of feeder positions for both current and future needs.
Additional improvements included reworking the connection from the high-voltage bay to the station transformer and moving the sectionalizing switch on the HV structure.
