New Study Warns Net-Zero Energy Plans Could Threaten Grid Reliability in the Great Lakes Region

Midland, MI. -As the Great Lakes region moves toward ambitious net-zero energy goals, a new study from the Mackinac Center for Public Policy raises alarms about the potential risks to the region’s electricity reliability. Titled Shorting the Great Lakes Grid: How Net Zero Plans Risk Energy Reliability, the study explores how the push for renewable energy sources like wind and solar could lead to power shortages and blackouts across seven states in the region: Illinois, Indiana, Michigan, Minnesota, Ohio, Pennsylvania, and Wisconsin.

Net-Zero Transition: A Double-Edged Sword for the Grid?

Across the United States, policymakers are pushing for a transition to net-zero carbon emissions by 2050. In the Great Lakes region, 32 of the 38 major investor-owned utilities have committed to these targets. This means that many states are retiring coal and petroleum plants and increasing their reliance on wind and solar energy.

While this transition is seen as crucial for reducing carbon emissions, the study warns that the move could compromise the reliability of the electric grid. Renewable energy sources like wind and solar are weather-dependent, meaning they cannot consistently provide the steady supply of electricity needed to meet daily demands. According to the study’s co-author Joshua Antonini, this reliance on weather-dependent energy sources could leave the region vulnerable to energy shortages.

Concerns Raised by Grid Operators

The report highlights that grid operators in the region have serious concerns about the readiness of the current infrastructure to support the transition to renewable energy. The Midcontinent Independent System Operator (MISO), which oversees much of the Midwest’s electricity grid, has projected that by 2032, none of the five Great Lakes states in its area will have enough electricity capacity to meet expected demands. This gap between supply and demand could result in rolling blackouts and energy shortages during peak times, especially if renewable energy sources fail to deliver adequate power.

“The modern electric grid is an essential aspect of our modern lives,” said Jason Hayes, co-author of the study and director of energy and environmental policy at the Mackinac Center. “We all rely on it to turn on the lights, to keep food refrigerated, to warm us in the winter, and cool us in the summer.”

A Larger Issue: Grid Dependence and the Domino Effect

One of the key findings in the study is the interconnected nature of the grid. Utilities that cannot generate enough power from their own renewable sources often plan to purchase electricity from neighboring states. However, this strategy assumes that those neighboring states will not be facing the same energy shortages. If multiple states within the region adopt similar net-zero policies and experience power shortages at the same time, the study warns that there could be widespread blackouts across the entire grid.

Antonini stressed the importance of course-correcting before it’s too late: “If we continue down this path, we should expect shortages and blackouts. Lawmakers and utilities must dismantle these harmful policies and reassess their energy strategies.”

Recommendations for a More Reliable Energy Future

The study doesn’t just highlight the risks; it also offers key recommendations to help ensure a more reliable energy future. These include:

• Maintaining a diverse energy portfolio: Instead of relying solely on renewable sources, states should ensure their energy portfolios include reliable power sources, such as natural gas and nuclear energy.
• Balancing environmental goals with basic energy needs: While reducing carbon emissions is important, the study argues that states must also ensure they are meeting the basic electricity needs of their residents.
• Reevaluating incentive structures: Current incentives that push utilities to focus heavily on renewables may need to be rebalanced to prioritize reliable and affordable energy.

By diversifying their energy sources and ensuring that the grid can handle periods of peak demand, states in the Great Lakes region could avoid the risks of shortages and blackouts while still working toward their environmental goals.

The Energy Debate: Finding a Balance

As the energy debate heats up, the Mackinac Center’s study serves as a stark reminder of the complex challenges that accompany the transition to a net-zero future. The balance between environmental sustainability and reliable energy will be a key issue for policymakers and utility companies in the coming years.

For the Great Lakes region, the stakes are high. As the push for clean energy accelerates, the need to ensure that electricity remains reliable and affordable will be more critical than ever. The study’s authors hope that their findings will prompt a reevaluation of energy policies across the region before it’s too late.
