Project Increases Reliable Electrical Capacity Without Changing River Operation
The Twin Falls dam on the Menominee River, bordering Wisconsin and the Upper Peninsula of Michigan, was built in 1912. The hydroelectric dam has been repaired and upgraded many times over its life.
There were two primary issues at Twin Falls dam: inadequate spillway capacity and an aging powerhouse. Both created safety issues, even though the Twin Falls impoundment structures were in good condition and licensed to operate until 2040. However, the powerhouse, also built in 1912, was not in condition to operate safely for the duration of the license.
Black & Veatch solved both challenges by providing design and project management for the new powerhouse and spillways. New spillway gates were installed and a new powerhouse was built on the opposite abutment of the dam from the existing plant. By building on the Wisconsin side of the river, the old facility on the Michigan side was able to remain in operation during construction.
“The key values that Black & Veatch brought to this project were their deep technical expertise and experience building hydroelectric projects.”
