Low Rhine water level to hit output at Staudinger 5, Datteln 4 coal plants
05 Aug 2022
Low water
levels on the Rhine, Germany’s main shipping artery, will affect output over
the coming month from major coal-fired power stations, one east of Frankfurt
and another in the northern Ruhr area, notes on the website of power bourse EEX
showed on Thursday.
The
Staudinger 5 plant has 510 megawatts of capacity and is operated by Uniper and
situated on the Main, a major Rhine tributary.
Its output
may be irregular until Sept 7 “due to a limitation of coal volumes on site”
caused by the low level of the Rhine, according to the document on EEX’s
transparency site.
Another
document posted late on Thursday morning said the 1,100 MW Datteln 4 plant may
also see irregular output to Sept 7 due to water levels.
Germany last
month agreed to reactivate its coal-fired power plants or extend their
lifespans in response to its worst energy crisis in generations, triggered by
dwindling supplies of Russian gas.
But shallow river levels following a hot, dry summer mean that barges taking
coal feed stock to generating plants can only sail with partial loads. Similar
conditions caused a fall in output at power stations and hit profitability at
chemical manufacturing plants in 2018.
A reference Rhine waterline level at Kaub, where vessels need about 1.5 metres
of clearance to sail fully loaded, fell to only 55 centimetres on Thursday.
Kaub hit 25
cm at one point in 2018.
A heat wave
this week has also boosted transport prices on the river as fewer vessels can
travel on it and pass through choke points, tightening transport space.
Low water
likewise affects power prices [EL/DE] as well as other commodities such as
mineral oil products and grains.
Warming
rivers in recent weeks have also curtailed French supplies of cooling water to
nuclear plants, contributing to tightness in the European power system and
driving up spot electricity prices.
