A ‘Wedge’ of Saltwater Is Making Its Way Up the Mississippi

New Orleans’ drinking water is under threat.

For much of its history, the Mississippi River has been a churning mass of water, the collected output of a watershed that stretches across 32 American states and two Canadian provinces. Its power is unquestionable; when the Mississippi meets the Gulf of Mexico, the sheer force of the river keeps the saltwater of the Gulf from making its way upstream.

Except for right now. Drought in the central U.S. has made the Mississippi drop to near-record lows, and the Gulf of Mexico is encroaching upwards. A “wedge” of saltwater at the bottom of the river has been making its way upstream, threatening to inundate drinking water plants in and around New Orleans (CNN has a good graphic that shows what the wedge looks like). This is a big problem: As Colbi Edmonds reports in TheNew York Times, water treatment plants aren’t designed to handle water with high salinity levels, which can corrode pipes.

Governor Jon Bel Edwards of Louisiana has requested a federal emergency declaration, and Mayor LaToya Cantrell of New Orleans has already signed a city-level emergency declaration. The Army Corps of Engineers, meanwhile, is hard at work trying to raise an underwater sill it had built in the river back in July to protect against the saltwater; officials say they want to make the sill 25 feet higher, though even that will only serve to buy about 10 or 15 days rather than stop the saltwater altogether. The only thing that can really stop the saltwater is rain, and none is forecasted for the near future.

This isn’t the first time saltwater has made its way upriver (it also happened in 1988), but this is the second year in a row where drought has made the river’s water levels drop so dramatically. In 1988, the saltwater intrusion was solved with an unexpected burst of water on the river; this time around, officials think the problem could last until January. And if the drought continues into next year, it’s likely they’ll be facing the same problem then.

In the meantime, the Corps is also organizing barges to transport drinking water to New Orleans and the other communities that stand to be affected. In a press conference on Friday, Governor Edwards urged people not to stock up on drinking water; a representative of the Army Corps told CNN that it “fully anticipates the capability to meet the need of up to 36 million gallons per day that could be required.”

This Natural Gas Plant Is a Poster Child for America’s Grid Weirdness

At least one natural gas plant in America’s biggest energy market that was scheduled to shut down is staying open. Elgin Energy Center, an approximately 500 megawatt plant in Illinois approximately 40 miles northwest of downtown Chicago was scheduled to shut down next June, according to filings with the Federal Energy Regulatory Commission and officials from PJM Interconnection, the country’s largest regional transmission organization, which governs the relevant portion of the U.S. grid. Elgin’s parent company “no longer intends to deactivate and retire all four units ... at the Elgin Energy Center,” according to a letter dated September 4 and posted to PJM’s website Wednesday.

The Illinois plant is something of a poster child for PJM’s past few years. In 2022, it was one of many natural gas plants to shut down during Winter Storm Elliott as the natural gas distribution seized up. Its then-parent company, Lincoln Power — owned by Cogentrix, the Carlyle Group’s vehicle for its power business — filed for bankruptcy the following year, after PJM assessed almost $40 million in penalties for failing to operate during the storm. In June, a bankruptcy court approved the acquisition of the Elgin plant, along with one other, by Middle River Power, a generation business backed by Avenue Capital, a $12 billion investment firm, in a deal that was closed in December.

Trump’s Odd Attack on German Energy Policy

What’s a “normal energy plant”?

In the closing minutes of the first presidential debate tonight, Donald Trump’s attacks on Kamala Harris took an odd, highly specific, and highly Teutonic turn. It might not have made sense to many viewers, but it fit into the overall debate’s unusually substantive focus on energy policy.

“You believe in things that the American people don’t believe in,” he said, addressing Harris. “You believe in things like, we’re not gonna frack. We’re not gonna take fossil fuel. We’re not gonna do — things that are going to make this country strong, whether you like it or not.”

What Would Trump Do About Climate Change? Something About the Mayor of Moscow’s Wife.

Hunter Biden also made an appearance in Trump’s answer to the debate’s one climate question.

Well, it happened — over an hour into the debate, but it happened: the presidential candidates were asked directly about climate change. ABC News anchor Linsey Davis put the question to Vice President Kamala Harris and former President Donald Trump, and their respective answers were both surprising and totally not.

Harris responded to the question by laying out the successes of Biden’s energy policy and in particular, the Inflation Reduction Act (though she didn’tmention it by name). “I am proud that as vice president, over the last four years, we have invested a trillion dollars in a clean energy economy,” Harris noted.
