Michigan’s ambitious clean energy laws face a peninsula-sized hurdle

Last year, Michigan adopted a clean energy standard

Last year, Michigan became one of the latest states to adopt a clean energy standard, passing sweeping legislation that calls for utilities there to use 100 percent clean electricity by 2040 and sets targets for renewable energy development, among other requirements. 

The Michigan Public Service Commission’s Role in the Clean Energy Transition

Now, it’s rolling out those laws. And the Michigan Public Service Commission, the energy regulators responsible for that rollout, must pay special attention to the Upper Peninsula. The commission has until December 1 to recommend whether — and how — the legislation should be adjusted to accommodate its people, businesses, and utilities. 

Challenges in the Upper Peninsula

They’ve got their work cut out for them: The Upper Peninsula, known colloquially as the U.P., is a huge, sparsely populated region in the north, separated from the rest of the state by the Straits of Mackinac and wedged between lakes Superior, Michigan, and Huron. The U.P. has a lot of utilities for its small population of just over 300,000, requiring a higher level of cooperation among them. Plus, the grid was built with power-hogging industries like mining and paper mills in mind, and fluctuating industrial demand has meant people who live in the region have faced high costs over the years. Some utilities have charged residents rates that are among the highest in Michigan and the country.

The Challenge of Natural Gas Plants

And the Public Service Commission has to ensure that the natural gas plants it approved in 2017 as a cleaner alternative to coal don’t prevent Michigan from achieving its clean energy goals. 

Those natural gas plants are powered by reciprocating internal combustion engines, called RICE units, that went online just five years ago and were built to last for decades — that is, beyond the state’s 2040 goal for clean energy. While the mining company Cleveland-Cliffs agreed to pay half of the $277 million price tag, the rest of the cost was passed on to more than 42,000 utility customers. 

Michigan’s new energy laws specifically mention the U.P.’s expensive new natural gas engines as a hurdle and ask the Public Service Commission to figure out what to do.

Opinions and Perspectives

The commission is juggling a lot of opinions. 

Mining officials and employees spoke in favor of continuing to run the RICE units at a public hearing held by the commission this summer. 

Ryan Korpela, the general manager for Cleveland-Cliffs’ Tilden Mine, asked commissioners to allow the natural gas engines to operate without requiring renewable energy credits or new power generation, calling them “the perfect solution to a difficult problem,” and noting that ratepayers already foot the bill.

Officials with Cleveland-Cliffs say that the engines are cleaner and more efficient than coal, saving customers money on transmission costs. But organizations like the Sierra Club have spoken out against installing them in places like neighboring Wisconsin, arguing that burning methane — the main component of natural gas — harms both the climate and the people living next to the plants. The climate think tank RMI says many comparisons of coal and gas only consider end-use emissions, and don’t account for methane leaks during production and transportation. According to an RMI analysis published last year, those leaks can put the climate impacts of natural gas on par with coal (when emitted into the atmosphere, methane is about 80 times as potent as carbon dioxide).

The utility that operates the RICE units, Upper Michigan Energy Resources Corporation, is working to deploy renewables, said spokesperson Brendan Conway in an email, but they’re balancing that with an immediate need for reliable energy: “These units serve that critical function in a part of the state with limited transmission access.”

Michigan’s Ambitious Clean Energy Goals

Across the country, four states have 100 percent renewable portfolio standards, while 16 states have adopted broader 100 percent clean electricity standards, according to Lawrence Berkeley National Laboratory’s August report. (Clean energy includes a wider array of technologies than renewables, so that number doesn’t include states like Vermont, which put a renewable energy standard into law earlier this year.) 

Galen Barbose, a staff scientist who authored the report, said Michigan’s goals are pretty ambitious. 

“Most other 100 percent states have targets that are further out in time,” he said. “By setting that 100 percent target for 2040, Michigan is one of the more aggressive states in terms of the timeline.” It is also approaching the transition more incrementally than some other states, Barbose said, aiming to get 80 percent of its energy from clean sources by 2035. 

Reliability and Grid Stability

Looming in the background of Michigan’s energy transition is the instability of the electrical grid, which can have serious consequences for the people living in the U.P. 

“A squirrel sneezes and the power goes out,” said Tori McGeshick, describing how some locals see reliability there. McGeshick is a member of the Lac Vieux Desert Band of Lake Superior Chippewa Indians who now lives across the border in northern Wisconsin. She works as the tribe’s climate resilience coordinator.

Utilities often take longer to respond to power outages in more remote areas, she said, and unreliable power has had a profound effect on her community, especially elders and people with specific medical needs. 

“It’s also affecting our harvesting rights,” McGeshick told Grist. “A lot of people harvest or hunt or fish during the different seasons, and when a power outage occurs, all of that — supplies — also is lost.” She added that the Public Service Commission should solicit more tribal input as it weighs the new legislation against the infrastructure, cost, and reliability of the grid. 

The Future of Energy in the U.P.

Not everyone agrees that natural gas is a long-term solution to reliable, affordable energy. Roman Sidortsov, an associate professor of energy policy at Michigan Technological University, said gas prices are variable and hard to predict. “People tend to forget that fossil fuels, and oil and gas in particular — it’s incredibly volatile business,” he said. “There’s very little stability in the prices.”

Sidortsov, who was a member of the state’s U.P. Energy Task Force several years ago, said the U.P. deals with different environmental factors and customers than the rest of the state; the grid was built to serve industries that aren’t as robust as they once were.

He thinks a lot of the region’s demand can be met with distributed generation — getting power through smaller, more localized sources of energy, something energy experts have discussed for years. Sidortsov said the right way forward is to develop the grid’s capacity for energy storage and smaller, spread-out renewable energy sources. 

“So when we are talking about achieving the goals set by the Legislature, it probably will require rethinking the grid in the U.P., updating the grid in the U.P., making sure that it can accommodate local solutions and distributed solutions.”

Michigan’s Leadership in Clean Energy

Michigan has become a leader among the states working toward an all-clean energy standard, said Douglas Jester, a managing partner at the policy consulting firm 5 Lakes Energy who helped develop the state’s laws. 

And while the clean energy standard still allows utilities to sell some amount of fossil fuel power back to the grid, it might not make financial sense come 2040, Jester said, as nearby states increasingly turn to renewables.
