WapakonetaArea Improvements Project

The proposed Wapakoneta Area Improvements Project would involve constructing approximately 15 miles of 138-kilovolt transmission line, two new substations and expanding an existing substation. The project area includes Pusheta, Washington, St. Marys, Duchouquet and Moulton townships in Auglaize County. The proposed project is being developed in coordination with the city of Wapakoneta and its electric department. The new transmission line and substations will add an additional power source to the area’s electric transmission grid. The improvements would benefit customers by improving reliability and supporting economic development.
