The Ahrensfelde gas turbine power plant (also GTKW Ahrensfelde ) in the Brandenburg municipality of Ahrensfelde in the Barnim district , only a few hundred meters from the Berlin city limits, was a reserve power plant that was operated to cover peak loads . The owner is Lausitz Energie Kraftwerke AG , which Vattenfall helped acquire when the lignite division was sold. The power plant is currently temporarily shut down due to a notification from the operator (as of August 2020).
Technology and history
Gas turbines
In 1990 four gas turbines powered by natural gas were put into operation, the generators of which have an electrical output of 38,340 kilowatts each at base load and 41,390 kilowatts at peak load under ISO standard conditions . The gas turbines of the type PG6541B the manufacturer Alstom have a net efficiency of 31%. The gas turbines could be brought up to nominal speed within seven minutes via quick start and synchronized with the network.
Control technology and data exchange
In October 2004 the control technology of the gas turbines and ancillary systems was renewed. The four gas turbines were previously equipped with four Speedtronic Mark IV process control systems from General Electric . As part of the modernization, the high-availability technology S7-400H from Siemens was used under the product name MACH7 . With the TMOS visualization system , this power plant and the Thyrow gas turbine power plant could be operated and monitored from the central control room.
At the end of 2009, the power plant was connected to the Geesthacht , Wendefurth , Markersbach and Goldisthal pumped storage power plants via a data ring built by Vattenfall Europe Netcom . The control center was in Goldisthal.
Since July 1, 2017, the control technology monitoring (observation) of the systems has been carried out via the Schwarze Pump power plant in the very south of the state of Brandenburg. However, the necessary switching operations were only carried out on site by GMB. After winning a tender by the Federal Network Agency in 2020 for the capacity reserve, all control connections from the GTKW Ahrensfelde to the Schwarze Pump power plant were changed so that the gas turbines could also be started and operated from this location.
Natural gas storage
On October 31, 2010, after a construction period of around two years, an underground tube storage facility for storing natural gas was put into operation on the power plant site . The storage facility consists of pipes with a total length of 2.7 km and a diameter of 1.40 m and can store a working volume of natural gas of around 360,000 m³. The natural gas storage facility enabled the power plant to operate independently of the natural gas network for a period of six hours. The investment costs for the natural gas storage facility, together with the natural gas storage facility at the Thyrow gas turbine power plant , totaled 33.5 million euros.
business
In 2010 the power plant was in operation for around 600 hours . In the following years it was used less and less and from 2016 hardly any more (see below the development of greenhouse gas emissions). In preparation of the capacity reserve for October 1, 2020, successful test runs were carried out with all four available gas turbines in June and July 2020.
Capacity reserve
In February 2020, the four gas turbines A to D received a bid for 120 megawatts in the capacity reserve tender from the transmission system operator . The reserve power must be provided from October 1, 2020 to September 30, 2022.
Mains connection
The power plant is connected to the power grid of the transmission system operator 50Hertz Transmission at 110 kV high voltage level via the substation in Berlin-Malchow .
Greenhouse gas emissions
The table shows historical carbon dioxide emissions. Since the emissions were higher than the emission allowances in the periods 2005–2007 and 2008–2012 , the operator had to purchase emission allowances in the EU emissions trading system.
