First new transformer arrives at Boomer Lake substation this week

May 15, 2019

STILLWATER, Okla. (May 15, 2019) - Stillwater Electric Utility received one of the two substation transformers replacing older versions at the Boomer Lake substation Tuesday. The second transformer will arrive later this week. This transformer is the first of six substation transformers ordered to replace aging transformers at other distribution substations.

These new, more reliable transformers will offer a significant increase in capacity for Stillwater’s electric system. The new transformers will provide an increase in capacity from 20mVA (million Volt Amps) to 28mVA each. This increase will not only help with reliability, but will accommodate increasing load on the system.

The transformer arrived Monday evening after a multiday trip from the factory in Canonsburg, Pennsylvania. A 775-ton crane placed the 85,000-pound transformer on its foundation Tuesday morning.
