Ørsted: Asnæs Power Station generates green power
The new wood chip-fired unit 6 at Asnæs
Power Station will supply heat together
with Asnæs Power Station’s boiler and
Kalundborg Forsyning’s large heat pump.
The green power from wind and solar PV is
thus utilised when it’s available at competitive
prices, while wood chips from sustainably
managed forests ensure that Kalundborg’s
need for process steam for the industry,
district heating for homes and power
for Denmark is fully covered without using
coal, while delivering a high reliability of
supply and a high degree of flexibility.
With Asnæs 6, another important step
will be taken towards the complete phaseout
of coal at Ørsted’s power stations.

LEAG: Brandenburgischer
Koalitionsvertrag stellt gültigen
Braunkohlenplan in Frage
• Investitionsentscheidung für den Welzower
Teilabschnitt II braucht Rechtssicherheit
(leag) Der Koalitionsvertrag der drei künftig
in Brandenburg regierenden Parteien
SPD, CDU und Grüne stellt den gültigen
Braunkohlenplan für die Erweiterung des
Tagebaus Welzow-Süd in Frage. Bei einem
Ausschluss von Umsiedlungen wäre die
Nutzung des Teilfeldes Welzow-Süd II
nicht mehr möglich und hätte erhebliche
Konsequenzen für Beschäftigung und
Wertschöpfung in der Lausitzer Region.
„Der Koalitionsvertrag stellt eine deutliche
Zäsur für unser Unternehmen dar. Damit
würde der geltende Braunkohlenplan
Makulatur und unser Lausitzer Revierkonzept
in Frage gestellt“, stellt der LEAG-Vorstandsvorsitzende
Dr. Helmar Rendez fest.
„Dieser Vertrag erschwert zudem die auf
Basis unseres Braunkohlengeschäfts eingeleitete
Entwicklung neuer Geschäftsfelder.“
Die Lausitz Energie Bergbau AG und Lausitz
Energie Kraftwerke AG (LEAG) hatte
bei der Vorstellung ihres Revierkonzeptes
im März 2017 angekündigt, im Jahr 2020
eine Investitionsentscheidung über die
Weiterführung des Tagebaus Welzow-Süd
zu treffen. Grundlage dafür sollte die energiewirtschaftliche
Notwendigkeit, die
Strommarktentwicklung sowie die energiepolitische
Ausrichtung der Bundesregierung
sein.
„Wir sehen weiterhin die energiewirtschaftliche
Notwendigkeit für eine Inanspruchnahme
des Teilabschnitts Welzow
Süd 2“, bekräftigt Dr. Rendez. „Wenn infolge
der Umsetzung der KWSB-Empfehlungen
durch die Bundesregierung Kraftwerkskapazitäten
vorzeitig stillgelegt werden
und dadurch die Kohlemengen einer
Erweiterung des Tagebaus Welzow-Süd
nicht mehr genutzt werden könnten, beraubt
sich Deutschland einer wichtigen
Option, seine gesicherte Versorgung in
Engpasssituationen mit der einzig wirtschaftlichen
gesicherten Leistung durch
die Braunkohleverstromung aufrecht zu
erhalten“. (193510836)

Ørsted: Asnæs Power Station
generates green power
• First green power generated by the turbine
at the new wood chip-fired unit 6
on 20 November.
(orsted) For more than 30 months, suppliers,
technicians and project employees
have been working hard on making Asnæs
Power Station in Denmark capable of generating
process steam, heat and power
without using coal. One of the most important
pieces of the big puzzle fell into place
on 20 November when the unit’s generator
was connected to the Zealand grid and
generated power for the first time.
The technicians have carried out countless
preparations and tests prior to the energisation
of the generator.
“It’s fantastic that we’ve come this far
with the project. In August, we were able to
supply the first green district heating and
process steam to our customers, and now
we’ve connected the unit to the grid and
generated green power for the Zealand
grid,” says Henrik Boye Jørgensen, Senior
Project Manager at Ørsted and responsible
for the construction of Asnæs Power Station’s
unit 6.
The new turbine has a capacity of 25MW
power and 129MJ/s process steam and district
heating. To generate power, the steam
must be fed into the turbine at a pressure of
100 bar and a temperature of 540°C.
Green energy with
a high reliability of supply
Ørsted initiated the conversion of Asnæs
Power Station in October 2017 to enable
the power station to replace coal with sustainable
wood chips in the future.
Ørsted partners with Pict Offshore
to develop game-changing
technology for offshore wind
operations and maintenance
(orsted) Ørsted has acquired a 22.5% share
in Pict Offshore, the Scottish developer of
an innovative technology set to transform
the way technicians access offshore wind
turbines.
The Get Up Safe (GUS) system, developed
in partnership between Ørsted and
Pict Offshore, is a motion compensated
hoist solution that enables technicians to
safely transfer between small moving vessels
and offshore wind turbines.
Using this technology means that technicians
will no longer have to step from a
moving boat onto a ladder and then climb
(sometimes over 20 metres) to reach the
base of the turbine. Instead they can clip
onto the system and be safely and effortlessly
hoisted up to the turbine base directly
from the boat.
The system’s motion compensation capability
means that the hoist automatically
adjusts the line position to take account of
the boats movements so that even in periods
of high and varying wave heights,
there is no danger of collision between the
technician and the boat.
In addition, the technology removes the
need for external access ladders on the turbines,
reducing the amount of steel required
in the structure and provides further
potential for cost reduction.
The technology is patent-protected and in
the final stages of development. More than
1,600 successful hoists have already been
conducted at Ørsted sites as part of the
testing process.
Mark Porter, Senior Vice President for
Offshore Operations at Ørsted, said: “The
offshore wind sector already has a proven
track record of innovation and rapid cost
reduction, and we’re continually looking at
new technologies to enhance both the construction
and maintenance of our projects.
