Energiewende Damages German Industry

Germany's Isar Nuclear Power Plant
We've been following the unintended consequences of Germany's "Energiewende" for some time now. Ever since that nation made the hasty decision to phase out its nuclear power plants in favor of renewables in 2011, the news has been nothing but bad.

Electricity prices are rising along with coal use and carbon emissions. Now comes word that German industry, the heart of its export-led economy, is beginning to suffer thanks to the inevitable grid instability wrought by the "Energiewende."

Here's the latest from Spiegel Online:
It was 3 a.m. on a Wednesday when the machines suddenly ground to a halt at Hydro Aluminium in Hamburg. The rolling mill's highly sensitive monitor stopped production so abruptly that the aluminum belts snagged. They hit the machines and destroyed a piece of the mill. The reason: The voltage off the electricity grid weakened for just a millisecond.

Workers had to free half-finished aluminum rolls from the machines, and several hours passed before they could be restarted. The damage to the machines cost some €10,000 ($12,300). In the following three weeks, the voltage weakened at the Hamburg factory two more times, each time for a fraction of second. Since the machines were on a production break both times, there was no damage. Still, the company invested €150,000 to set up its own emergency power supply, using batteries, to protect itself from future damages.

"It could have affected us again in the middle of production and even led to a fire," said plant manager Axel Brand. "That would have been really expensive."
When Spiegel looked at the numbers, it found that the situation at Hydro Aluminum wasn't an isolated case:
A survey of members of the Association of German Industrial Energy Companies (VIK) revealed that the number of short interruptions to the German electricity grid has grown by 29 percent in the past three years. Over the same time period, the number of service failures has grown 31 percent, and almost half of those failures have led to production stoppages. Damages have ranged between €10,000 and hundreds of thousands of euros, according to company information.
The lesson here: you can't remove a baseload source of energy like nuclear from the electric grid and replace it with intermittent sources like renewables and not take a hit in reliability. That was part of the point of the online package we produced a few weeks ago concerning nuclear energy's unmatched reliability. It doesn't matter whether the grid gets stressed by sustained heat, cold, or a long production run at a major industrial facility, without always-on power, you're putting a lot at risk.

So what's next for German industry? Apparently, a lot of businesses are wondering if it isn't time to leave.  "In the long run, if we can't guarantee a stable grid, companies will leave (Germany)," says Joachim Pfeiffer, a parliamentarian and economic policy spokesman for the governing center-right Christian Democratic Union (CDU). "As a center of industry, we can't afford that."

So where might they go? I've got a few ideas. Why not follow German auto manufacturing giant BMW? The company opened a manufacturing facility in Spartanburg, South Carolina in 1994. The state has seven reactors that provide more than 51% of its electricity. There won't be any questions about reliability there.

"The latest" is from almost two years ago.

Given the increase in electricity production from renewables in the past few years, all manufacturing in Germany should have halted and there should have been numerous cascading failures like the US Northeast Blackout of 2003.

So why hasn't that happened?

How Nanomaterials Can Make Nuclear Reactors Safer and More Efficient

The following is a guest post from Matt Wald, senior communications advisor at NEI. Follow Matt on Twitter at @MattLWald.

From the batteries in our cell phones to the clothes on our backs, "nanomaterials" that are designed molecule by molecule are working their way into our economy and our lives. Now there’s some promising work on new materials for nuclear reactors.

Reactors are a tough environment. The sub atomic particles that sustain the chain reaction, neutrons, are great for splitting additional uranium atoms, but not all of them hit a uranium atom; some of them end up in various metal components of the reactor. The metal is usually a crystalline structure, meaning it is as orderly as a ladder or a sheet of graph paper, but the neutrons rearrange the atoms, leaving some infinitesimal voids in the structure and some areas of extra density. The components literally grow, getting longer and thicker. The phenomenon is well understood and designers compensate for it with a …

Missing the Point about Pennsylvania’s Nuclear Plants

A group that includes oil and gas companies in Pennsylvania released a study on Monday that argues that twenty years ago, planners underestimated the value of nuclear plants in the electricity market. According to the group, that means the state should now let the plants close.

Huh?

The question confronting the state now isn’t what the companies that owned the reactors at the time of de-regulation got or didn’t get. It’s not a question of whether they were profitable in the '80s, '90s and '00s. It’s about now. Business works by looking at the present and making projections about the future.

Is losing the nuclear plants what’s best for the state going forward?

Pennsylvania needs clean air. It needs jobs. And it needs protection against over-reliance on a single fuel source.


What the reactors need is recognition of all the value they provide. The electricity market is depressed, and if electricity is treated as a simple commodity, with no regard for its benefit to clean air o…

Why America Needs the MOX Facility

If Isaiah had been a nuclear engineer, he’d have loved this project. And the Trump Administration should too, despite the proposal to eliminate it in the FY 2018 budget.

The project is a massive factory near Aiken, S.C., that will take plutonium from the government’s arsenal and turn it into fuel for civilian power reactors. The plutonium, made by the United States during the Cold War in a competition with the Soviet Union, is now surplus, and the United States and the Russian Federation jointly agreed to reduce their stocks, to reduce the chance of its use in weapons. Over two thousand construction workers, technicians and engineers are at work to enable the transformation.

Carrying Isaiah’s “swords into plowshares” vision into the nuclear field did not originate with plutonium. In 1993, the United States and Russia began a 20-year program to take weapons-grade uranium out of the Russian inventory, dilute it to levels appropriate for civilian power plants, and then use it to produce…
