The City of Piqua Power System has completed its final primary voltage cutover, officially retiring the last 4 kilovolt (kV) power lines in the city and marking the end of a project that has spanned multiple decades.
On Wednesday, September 17, crews transitioned 76 customers on Gray, McKinley, Wilson, Garfield, Grant and South streets from the 4 kV system to the modern 13 kV distribution network. Power was interrupted from approximately 9 to 11:30 a.m. during the switchover, which was the last step in eliminating all 4 kV infrastructure from Piqua’s electric grid.
“This milestone is the result of years of steady progress and investment,” said RJ Monnier, director of the Piqua Power System. “The conversion to 13 kV service means our customers will benefit from improved reliability today and a grid prepared to support Piqua’s growth tomorrow.”
The upgrade enhances reliability, safety and capacity for residents and businesses and allows Power System crews to move forward with other important projects throughout the city. The conversion from 4 kV to 13 kV distribution has been underway for over two decades, with crews gradually replacing older infrastructure throughout the city.
