The Public Works Board and the City Council will be touring the new substation this week. The substation is scheduled to be online by the end of October.
The Light and Water Utility recently constructed a new open framed distribution substation on Tyranena Park Road just west of Rock Creek. The new substation consists of two three-phase transformers with load tap changers with an approximate rating of 25/46.6 MVA that will step voltage from 138,000 volts to 24,940 volts, transformer protection, circuit reclosers/breakers operated at 24,940 volts, and associated steel structures and materials required to connect the equipment to the transmission and distribution systems. The developed area for the new substation site is approximately 77,000 square feet (325 feet by 240 feet).
The substation construction consisted of stripping unsuitable soil from the construction site, filling with appropriate granular backfill, installation of foundations to support equipment, ground grid for safety, conduit and wiring for power and control of equipment, equipment and steel for operation, and other typical items for a municipal substation to ensure a safe and effective installation.
