LANSING — As Michigan regulators prepare to decide the future of 13 hydroelectric dams owned by Consumers Energy, local officials, business owners and community leaders are urging the state to approve the proposed sale, arguing that removing the dams could damage local economies, reduce property values and eliminate a source of clean, renewable electricity.
The comments were filed with the Michigan Public Service Commission (MPSC), which is expected to decide by early September whether to approve Consumers Energy’s plan to sell the hydroelectric facilities to Confluence Hydro, a newly formed company that has pledged to continue operating the dams and invest hundreds of millions of dollars in repairs and upgrades.
The decision comes as Michigan grapples with two competing priorities: maintaining aging infrastructure while expanding clean energy generation to meet rising electricity demand driven by electric vehicles, advanced manufacturing and increasingly, artificial intelligence data centers.
If the sale is rejected, Consumers Energy has previously indicated it would begin decommissioning the dams, potentially leading to their eventual removal.
Local Communities See Economic Stakes
Supporters of the sale say the dams represent far more than electricity generation.
They argue the impoundments created by the dams support lakefront property values, boating, fishing, tourism and local businesses throughout several Michigan communities. They also contend that removing the dams could fundamentally alter waterfronts that residents have enjoyed for generations.
Business organizations and local governments told regulators that preserving the dams would help protect jobs, tax revenue and recreational opportunities while allowing continued production of renewable hydropower.
Environmental Groups Remain Skeptical
Environmental organizations continue to oppose the transaction, arguing the ownership structure raises questions about long-term accountability and whether the new owner would have sufficient financial resources to maintain aging infrastructure for decades.
Critics also argue some rivers could benefit environmentally if certain dams were eventually removed, restoring fish passage and more natural river ecosystems.
The debate highlights a growing challenge facing Michigan and states across the country as dams built decades ago become increasingly expensive to maintain.
Aging Infrastructure Meets Growing Energy Demand
Consumers Energy has maintained that operating the hydroelectric facilities is no longer financially sustainable under its regulated utility business.
The proposed buyer has committed to investing approximately $275 million over the coming years to modernize and maintain the facilities.
The timing is significant.
Michigan policymakers are simultaneously encouraging development of energy-intensive AI data centers, electric vehicle manufacturing and advanced manufacturing facilities—all of which will require additional electricity supplies in coming years.
Although hydropower represents only a small percentage of Michigan’s electric generation, it provides carbon-free electricity that can operate around the clock, unlike solar and wind resources that depend on weather conditions.
A Decision With Statewide Implications
While the immediate case focuses on Consumers Energy’s hydroelectric portfolio, the MPSC’s decision could influence how Michigan approaches other aging infrastructure assets in the future.
Across the state, hundreds of dams are approaching or have exceeded their original design life, forcing policymakers, utilities and local governments to confront difficult questions about who should pay for maintenance, when removal makes more sense than repair, and how those decisions affect nearby communities.
The Consumers Energy case may become an important test of whether private investment can preserve aging hydroelectric infrastructure that utilities no longer consider economically viable.
The MPSC is expected to issue its decision later this summer.
