A year after the last wisps of smoke disappeared into the skies from the imposing chimneys of the Moorburg coal plant, hopes had grown that the mothballed site would see new life as Germany scrambles to secure energy supplies.
Moscow’s curtailing of gas exports to Germany in the wake of Russia’s invasion of Ukraine has forced Berlin to make the radical decision to restart coal power stations, at least temporarily.
However, infrastructure issues, worker shortages and logistical problems are proving to be major obstacles for the restart.

At Moorburg, operator Vattenfall GmbH has dashed hopes of new operations, saying that “restarting the plant would be neither technically, economically nor legally feasible.”
“Many parts have been dismantled and sold,” said Robert Wacker, director of the site.
Even power plants that had not been completely shut, but put in reserve to generate power only occasionally, are struggling with a complete reboot.
Further south from Moorburg, energy group Uniper SE is planning to fire up its Heyden 4 site, which had been a reserve plant since the middle of last year.
However, the company warned that its output would be affected by railway capacity limits in ferrying hard coal to the site.
Germany began winding down its coal-fired power plants in the past few years, in view of meeting a target to end the usage of fossil fuels by 2030.
The Ukraine war has upended those plans, as Moscow reduced energy exports to Germany in what Berlin believes is retaliation for its support for Kyiv.
The administration of German Chancellor Olaf Scholz has said it would stick to the 2030 coal exit goal, but in the meantime, it authorized the restart of 27 mothballed plants or those put in reserve to help fill the gap until March 2024.
With a capacity of 875 megawatts (MW), Uniper’s Heyden 4 figures as the largest on the list, while the Moorburg plant, in a suburb of Hamburg, had been one of the most modern in the world.
It was shut down in the summer of last year, just six years after it was put into service, in exchange for a public subsidy program aimed at cutting coal from Germany’s energy mix.
Since then, the operator has started dismantling and selling the parts that are not necessary for hydrogen — a priority for Germany’s future energy sources.
Before it closed, the plant generated about 1.1 terawatts per year — the equivalent of the electricity consumption of Hamburg, Germany’s second-largest city.
Now, the installation is no longer complete. In the turbine hall, thousands of small components have been packed away into boxes. A rotor, an element that allows the turbine to turn, is packed in aluminum, ready to be sent off. The transformer is also no longer functioning.
“Without the transformer, the power plant is no longer linked to the network and cannot produce any electricity,” the operator said.
Pointing at rust that has accumulated on the components over the past year, Vattenfall spokeswoman Gudrun Bode said: “We can’t restart a plant just like that.”
With winter around the corner, the race is getting tighter for Germany to ramp up its power generation capacity.
However, so far, only one — the Mehrum plant with a capacity of 690MW — has restarted. Besides technical issues, power suppliers are struggling with an acute worker shortage.
In Moorburg, “most of those who left have found a job, or are retired,” Wacker said.
Energy giant RWE AG said it is seeking several hundreds of workers as it prepares to reopen three plants with a capacity of 300MW each.
Logistics was also turning out to be tricky, with a drought further putting pressure on the distribution network.
The Rhine River has been a key route for coal transport to power plants in the west of the country, but record-low water levels over the past week have limited shipments and forced suppliers to turn to rail transport, putting further pressure on strained cargo trains.
Uniper has said Heyden 4’s operation would be “limited partly by limits of rail transport capacity bringing coal to the site.”
Energy supplier STEAG GmbH has also said that it would bring into operation two coal-fired plants from its reserve.
It has targeted November as a possible restart date, but it also noted that current rules require sites to have coal supplies for 30 days — something that would be unachievable “given the current tight logistics situation on rail transport.”
In a bid to unblock the jam, Berlin on Wednesday said it would prioritize coal and oil cargo over passenger travel this winter.
BUSINESS UPDATE: The iPhone assembler said operations outlook is expected to show quarter-on-quarter and year-on-year growth for the second quarter Hon Hai Precision Industry Co (鴻海精密) yesterday reported strong growth in sales last month, potentially raising expectations for iPhone sales while artificial intelligence (AI)-related business booms. The company, which assembles the majority of Apple Inc’s smartphones, reported a 19.03 percent rise in monthly sales to NT$510.9 billion (US$15.78 billion), from NT$429.22 billion in the same period last year. On a monthly basis, sales rose 14.16 percent, it said. The company in a statement said that last month’s revenue was a record-breaking April performance. Hon Hai, known also as Foxconn Technology Group (富士康科技集團), assembles most iPhones, but the company is diversifying its business to
Apple Inc has been developing a homegrown chip to run artificial intelligence (AI) tools in data centers, although it is unclear if the semiconductor would ever be deployed, the Wall Street Journal reported on Monday. The effort would build on Apple’s previous efforts to make in-house chips, which run in its iPhones, Macs and other devices, according to the Journal, which cited unidentified people familiar with the matter. The server project is code-named ACDC (Apple Chips in Data Center) within the company, aiming to utilize Apple’s expertise in chip design for the company’s server infrastructure, the newspaper said. While this initiative has been
GlobalWafers Co (環球晶圓), the world’s No. 3 silicon wafer supplier, yesterday said that revenue would rise moderately in the second half of this year, driven primarily by robust demand for advanced wafers used in high-bandwidth memory (HBM) chips, a key component of artificial intelligence (AI) technology. “The first quarter is the lowest point of this cycle. The second half will be better than the first for the whole semiconductor industry and for GlobalWafers,” chairwoman Doris Hsu (徐秀蘭) said during an online investors’ conference. “HBM would definitely be the key growth driver in the second half,” Hsu said. “That is our big hope
The consumer price index (CPI) last month eased to 1.95 percent, below the central bank’s 2 percent target, as food and entertainment cost increases decelerated, helped by stable egg prices, the Directorate-General of Budget, Accounting and Statistics (DGBAS) said yesterday. The slowdown bucked predictions by policymakers and academics that inflationary pressures would build up following double-digit electricity rate hikes on April 1. “The latest CPI data came after the cost of eating out and rent grew moderately amid mixed international raw material prices,” DGBAS official Tsao Chih-hung (曹志弘) told a news conference in Taipei. The central bank in March raised interest rates by
