Turning Water into Electricity

Turning Water into Electricity – Calm lakes surrounded by colorful forest only visible from above. These photos were taken mid September, just as the colors were starting to turn.

A beautiful lake surrounded by forest here at Victoria Dam in Michigan.

Side note: looks like a few bloggers including my site, are having issues with comments and the like button being blocked. So incase you are reading this and the comment sectioned is closed, word press is at fault for this. I have not turned them off. Hopefully it can be fixed, I will let you know if I find anything out about this situation. 😊

At Victoria, water from the diversion dam flows through the intake structure at the dam into wood-stave pipeline and steel penstock to the turbines. The force of the water passing through the blades of the 65-inch diameter cast steel wheels drives the turbine and generators to produce electricity.

The Victoria units operate at 300 rpm with a maximum operating head of 215 feet. (Head—the difference in water elevation at the dam and the tailrace or discharge elevation.) With maximum head, a pressure of 93 pounds per square inch (psi) exists at the turbine water wheels.

After the water passes through the turbines, it is discharged into the west branch of the Ontonagon River, then into the main Ontonagon River, and finally into Lake Superior at the Village of Ontonagon.

Rainfall and melting snow throughout the 801-square-mile watershed upstream of the Victoria eventually end up as water at Victoria Dam. Some of this water is held in storage at UPPCO’s Bond Falls Reservoir, Bergland Dam, or Cisco Dam, and flows as river-run directly to Victoria. (UPPCO refers to the Upper Peninsula Power Company.)

At Victoria, this water is used for power generation. However, if the river-run exceeds the storage capacity of the Victoria Dam and the 850 cubic feet per second utilized by the turbines while operating at a full load, it is necessary to spill the excess water through the radial spill gates. Normally the greatest amount of water is spilled during the spring snow-melt or runoff.

Because water can be stored upstream of Victoria for release and use during dry periods, UPPCO is able to operate the power station about 80 percent of the time during the average year. The least amount of generation occurs during July and August when the river-runs are sometimes down to 150 cubic feet per second.
