As signs of climate change surface in Minnesota, policymakers and utilities are making a hard charge to transition to clean energy sources, but questions remain about whether the power grid will be ready.

Citing independent estimates, the U.S. Department of Energy said to meet demand for sources like wind and solar, the nation will need to expand transmission systems by 60% by 2030 and possibly triple them by 2050.

Amelia Cerling Hennes, managing director of the group Clean Energy Economy Minnesota, said the nation's current grid system is old, and was not designed for the newer approach to powering up cars, homes and businesses.

"As more of us convert to electric vehicles, and getting off of our natural gas-powered appliances at home; as we're electrifying things, we're going to need more electricity," Cerling Hennes pointed out. "The current system is just not going to cut it."

There has been promising news, such as the Midcontinent Independent System Operator last year approving $10 billion in projects to integrate more renewable energy. But Hennes warned completing a new transmission line can take up to a decade, and said there should be more urgency in permitting projects, without minimizing public input.

The process is playing out with a proposed transmission line project by Xcel Energy in parts of western Minnesota.

Molly Malone, manager of Minnesota community affairs for the renewable energy developer Invenergy, said they are putting together a wind project which would connect to Xcel's planned line.

"We're not only doing it because of the strong wind resource in the area, but also because there is transmission expansion happening," Malone pointed out. "That transmission expansion is critical to the development of our wind project. They go hand-in-hand."

Not only is grid space a deciding factor, but developers also have to navigate the many layers of approval, including regulators, local governments and buy-in from community members. Hennes noted not getting them all on the same page will make it harder to meet the state's zero-carbon energy goals.

"If we're going to have 100% clean energy by 2040, which is 17 years away, the window of time is pretty short," Hennes cautioned.

This spring, Minnesota lawmakers addressed certain permitting issues, but Gov. Tim Walz acknowledged efficiencies still need to be addressed next session. Around the U.S., the Lawrence Berkeley National Laboratory said it takes five years for the average project to be completed.

Advancing clean energy sources can be a tricky topic in oil-producing states like North Dakota.

But a nonpartisan analysis says the facts are clear about what causes electric bills to climb, and renewables aren't among them.

This month, a report from the independent think tank Energy Innovation says one third of U.S. households had to forego basic necessities to pay energy bills last year.

As the nation scales up the transition to sources like wind and solar power, those opposed to clean energy rebates and other climate policies say the movement is harming consumers - with higher costs to keep the lights on.

But report author Brendan Pierpont - director of electricity modeling for Energy Innovation - said the facts show otherwise.

"Nationally, we found big drivers of rising rates are climate change impacts, and extreme weather - and fossil fuel costs," said Pierpont, "like volatile natural gas prices, and utility investment in aging, expensive coal plants."

Gov. Doug Burgum has increasingly become a staunch supporter of oil and gas production, but North Dakota has been a top ten state for wind energy generation.

The report says states with significant clean energy growth have not generally experienced rate hikes above inflation.

Between 2010 and 2023, North Dakota was in the middle of the pack for rate increases, but still below the national average.

Those who oversee the power grid warn that the rapid push toward renewables could create reliability issues in the short term, especially with rising electricity demand from places like big data centers.

Grid improvement projects are taking shape, also affecting energy bills. But Pierpont suggested not enough of them are designed to expand transmission lines.

"It's only a pretty small portion of the total transmission and distribution pie that is expanding the grid," said Pierpont, "either to meet rising demand or to integrate new resources, like wind and solar."

Pierpoint said those cleaner sources are becoming much cheaper, and if utilities and grid operators focus more on larger projects that get them online, they'll offset the factors pushing electricity bills higher.

In 2022, the Midcontinent Independent System Operator approved a $10 billion transmission plan to accommodate growth in renewables. North Dakota falls under the MISO map.

Construction could begin in Minnesota later this year in the final phase of one of the nation's largest solar energy developments, after state regulators greenlighted a key permit.

The Minnesota Public Utilities Commission on Thursday approved the site permit requested by Xcel Energy. The utility is moving forward with plans to replace the Sherco coal plant site in Becker, about halfway between St. Cloud and Minneapolis. Two other solar arrays that are part of the development have already been approved, and construction began last year.

Katie Sieben, chair of the Minnesota Public Utilities Commission, summarized the significance of approving the third phase.

"It's certainly a very important project for Minnesota and the upper Midwest," Sieben pointed out.

Once fully operational, the company said the combined solar capacity would generate enough electricity to power more than 150,000 homes each year, on average. Regional utilities are under pressure to meet the state's goal of carbon-free electricity by 2040. Concerns from nearby landowners were brought up before the vote, such as the need to maintain vegetation around the site for aesthetic purposes.

Officials tied to the project stressed they are committed to long-term monitoring of plants and trees, in addition to special permit conditions.

Charles Sutton, representative for North Central States Regional Council of Carpenters and International Union of Operating Engineers Local 49, called in to the meeting and noted the positive impact construction is having on the local workforce.

"We appreciate the company's work," Sutton emphasized. "Continuing to partner with workers and ensuring that these projects are built by highly skilled workers that are local, and that are being paid family-sustaining wages and benefits."

Over the winter, Xcel closed the first generator of the Sherco coal plant. The remaining units will be phased out over the next five years. Xcel said it is also working with the state and local communities to bring new jobs and investments to areas affected by coal plant retirements.

So far, states like Wisconsin have largely escaped the worst of the summer heat affecting much of the nation but a group of scientists wants regional residents to pay closer attention to patterns affected by climate change, including weather disasters.

Science Moms bills itself as a nonpartisan group of climate scientists who engage with everyday people, namely other moms, on the need to address the effects of a warming planet.

Tracey Holloway, professor of energy analysis and policy at the University of Wisconsin-Madison and a member of the group, said a key point right now is extreme weather events should not be written off as typical.

"A lot of the disasters that we're experiencing wouldn't have occurred if it hadn't been for climate change," Holloway contended. "It doesn't seem quite right to use the term 'natural disaster' anymore."

Science Moms has a new ad campaign in Wisconsin and other states, referring to climate-fueled events as "unnatural" disasters. Engagement efforts like theirs coincide with public polling showing many Americans are worried about this issue, acknowledging climate change is underway. In a Gallup poll, only 55% of respondents said they think it will pose a serious threat in their lifetime.

Holloway pointed out the Wisconsin Initiative on Climate Change Impacts is a good resource for skeptics to turn to, or for those who are curious about what the data said.

"We are getting warmer but the biggest change in our temperatures is coming in the winter," Holloway explained. "Our winters are getting especially warm."

Even when some winters bring a lot of cold and snow, Holloway noted the cold is not as extreme as in past years. As for rain, the Initiative pointed out in Wisconsin, average precipitation has increased by 17%, or about 5 inches, since 1950. The Science Moms group hopes presenting the information will spur more conversation about the effects, and how community members can relay their concerns to decision-makers.
