Consumers Energy announced Friday morning that emergency public warning sirens and speaker systems near its dams will be tested next week.

Sirens near the Rogers, Hardy, and Croton hydroelectric generating plants on the Muskegon River will be tested on Tuesday, Aug. 15, at about 9:00 A.M.

Near the Tippy and Hodenpyl hydroelectric generating plants on the Manistee River, sirens will be tested on Wednesday, Aug. 16, at about 9:00 A.M.

Each test will include a voice message, a 30-second siren and a second voice message. The public does not need to take any action during the test.

The siren systems are tested each August and December and are required by the Federal Energy Regulatory Commission.
