Installation of a new 22-megawatt transformer at Ameren Missouri's Tisdale Substation in Boonville is complete, wrapping up a $1.86 million substation upgrade designed to improve reliability and accommodate growth in several mid-Missouri communities.
The new transformer replaces an older, 14-megawatt Tisdale Substation transformer that has been helping supply power to Boonville, Pilot Grove and Jamestown. It will meet the area's growing demand for power while backing up a second transformer that also distributes electricity from Tisdale Substation, at Tisdale and Sonya drives in the south central portion of Boonville.
"With the Tisdale Substation upgrade complete, we've increased our power delivery capacity in mid-Missouri," said Jason Haynam, an Ameren Missouri engineer. "That improves our service reliability and accommodates the growth we've seen in the Boonville area."
A segment of the project that will serve New Franklin and Franklin is currently under way. Ameren Missouri crews are in the midst of rerouting the power lines and individual transformers in both New Franklin and Franklin to connect them to the new Tisdale Substation transformer.
Those communities have been receiving their power from a nearly 100-year-old substation south of New Franklin, which will be decommissioned once the area's homes and businesses have been rerouted to the Tisdale Substation. Because the Tisdale Substation's distribution voltage differs from the voltage provided by the New Franklin lines, the project also calls for replacing the transformers connecting nearly 650 Ameren Missouri customers in the area to the electrical network.
The $742,000 rerouting project is expected to be complete by the end of July.
