Minnesota groups highlight financial and environmental risks of natural gas

A coalition of 10 environmental groups is trying to change the perception that natural gas is cheap or clean.

Editor’s note: This story has been updated to include comments from utility Xcel Energy.

With a billion-dollar gas-fired power plant proposal on the horizon, a new campaign in Minnesota is attempting to shift public opinion on the fuel by highlighting its ties to fracking and potential financial risks.

The strategy: challenge the perception that gas is cheap or clean. Or natural.

Once embraced by utilities and environmentalists as a cleaner-burning and less-expensive alternative to coal, natural gas transformed the nation’s electricity system over the last decade and a half, replacing more than 100 coal plants and smoothing the path for a surge of new wind and solar capacity.

Now, with the clock ticking to dramatically decrease climate emissions, growing awareness about its environmental side effects, and the economics of renewables and storage nipping at its heels, natural gas has lost its luster among many environmentalists. Yet utilities maintain that the fuel is still necessary in the near term to balance intermittent renewables.

The coalition of environmental and clean energy groups behind the “Energy We Can’t Afford” campaign believe utilities in the state have been too slow to recognize these trends, and they’re preparing to mobilize the public to help lobby against the approval of new natural gas power plants.

“We have an opportunity in 2021 to make a better decision for ratepayers, communities and our climate by investing in clean energy,” said Jessica Tritsch, senior representative for the Sierra Club’s North Star chapter, which is leading the campaign along with climate activist group MN350. Other coalition members include Fresh Energy, which publishes the Energy News Network.

Minnesota’s utilities have pledged to close all but one of the state’s remaining four coal plants, but their long-term plans call for building new natural gas plants while adding significantly to their renewable energy portfolios. 

Utilities have long argued gas offers the least polluting and least expensive option for providing baseload power that allows for greater renewable energy integration. 

Within the next several months, the Public Utilities Commission will begin reviewing integrated resource plans of Xcel Energy and Minnesota Power. Both propose investments in gas plants. Xcel, the state’s largest investor-owned utility, wants to build a $1 billion natural gas plant in Becker to replace the state’s largest coal facility, which will close by 2030.

Minnesota Power is a lead investor in the Nemadji Trail Energy Center gas plant in Superior, Wisconsin. The plant remains tied up in Minnesota in a Supreme Court case. Other Minnesota utilities, including Rochester Public Utilities, have also expressed interest in building natural gas plants to complement wind and solar investments.

Tritsch pointed to recent research by the Rocky Mountain Institute that suggests building solar, wind and storage would cost less than new natural gas plants.  Grid reliability would not suffer, either, the report concludes. If proposed gas plants were all built in the next five years they would “be uneconomic to continue operating in 2035, well ahead of the ends of their planned economic lifetime,” the institute’s report said.

A recent report from a Minnesota researcher working with the two organizations calculated that investing in clean energy instead of the two fossil gas plants could save ratepayers $600 million over the next 30 years, Tritsch said. 

Tritsch said the industry is accurate in highlighting that natural gas plants emit half the carbon of coal facilities. But the energy in fracking operations to extract and transport gas are not included in the calculation, she said. Nor has the leakage that invariably occurs in gas pipelines.

In a statement, Xcel Energy said it recognizes the destructiveness of methane leakage and plans to mitigate the problem through working with other utilities on two initiatives. Xcel this year joined “ONE Future,” a consortium of more than 20 natural gas companies aiming to limit methane emissions across natural gas supply chain to 1% or less by 2025.

The utility also said the proposed natural gas facility in Becker would emit only 20% of the carbon emitted by the coal units in 2019, and that the plant could someday incorporate new, carbon-free technologies such as renewable natural gas or hydrogen to reduce emissions even more.

“The Becker natural gas plant is an important part of our plans to retire all our coal in the Upper Midwest by 2030 and to add industry leading amounts of renewable energy to our system,” Xcel said. “We can deliver on our plan of 80% carbon reductions by using efficient natural gas to provide reliable electricity service when renewable energy is not available while also keeping bills low.”

Melissa Partin, a research professor in the Department of Medicine at the University of Minnesota, wrote the report MN350 and Sierra Club cite when discussing the health, safety and economic impacts of natural gas in the state. Methane leaking from natural gas systems heats the atmosphere 86 times faster over 20 years than carbon dioxide, the chief greenhouse gas emitted by coal plants, she said.

When burned for electricity, natural gas produces less carbon dioxide than coal, but “it’s still at a dangerous level,” she said. “The safest level is none.” The state’s 26 natural gas plants that produce electricity produced 3.6 million metric tons of carbon in 2018, Partin said. Since 2005 Minnesota has had 77 potentially dangerous incidents stemming from natural gas that cost $59 million in damage and three deaths, she said.

The new plants proposed in Minnesota are much bigger than the existing natural gas plants but perhaps more concerning, Partin said, is methane leakage at the extraction plant, pipelines and storage facilities. Some scientists think the Environmental Protection Agency’s data on methane leakage underestimates the problem.  

In the United States, 77% of natural gas comes from fracking. The fracking process produces “a whole host of other public health impacts from earthquakes to toxic water to air particulates and air pollutants and around the fracking sites,” Partin said.

Brett Benson, communications director for MN350, said the coalition wants Minnesotans to understand “natural gas is only natural when it’s in the ground.” Part of the coalition’s effort is to change the language to “fossil gas” or “fracked gas” to move away from the term “natural gas.”

When people learn that most natural gas comes from fracking, “their opinion of natural gas changes dramatically,” Benson said. For now, the coalition wants to continue Energy We Can’t Afford as an educational platform before using it for lobbying or testifying before regulators.

It isn’t the first attempt to try to rebrand the fuel. Other environmental groups have tried to get similar labels to stick. On the other side, proponents have also sought unsuccessful rebrands, such as when the U.S. Department of Energy last year began calling natural gas “freedom gas.”
