The Thyrow gas turbine power plant (also abbreviated to GTKW Thyrow) is a gas turbine power plant in the Märkisch Wilmersdorf district of the Brandenburg town of Trebbin in the Teltow-Fläming district . It is kept as a reserve power plant and is used exclusively to restore the network in the case of Schwarzwerdefall . The owner and operator is Lausitz Energie Kraftwerke AG .
In the immediate vicinity there is a transformer station and a traction current converter station.
Technology and history
The power plant was planned by VEB Wärmeanlagenbau Berlin and built by the Construction and Assembly Kombinat Ost (BMK Ost) from Potsdam. In 1987, the first four gas turbines (A to D) were put into operation, the generators of which have an electrical output of 37 megawatts each. Four more gas turbines (E to H) followed in 1989, the generators of which have an electrical output of 38 megawatts each. The gas turbines are of the types PG6461B and PG6541B from the manufacturer Alsthom (today Alstom ), which have a net efficiency of 31%. All gas turbines are operated exclusively with natural gas . An original single or mixed operation with heating oil is no longer possible since 2010, the necessary control technology has been adapted accordingly.
Thanks to the emergency diesel generator set at the site, the power plant is capable of black start in the event of a network breakdown . The power plant can be commissioned within seven minutes.
In October 2003 the control technology of the gas turbines and ancillary systems was renewed. The four PG6461B and PG6541B gas turbines that were delivered and commissioned by Alsthom in the 1980s were each equipped with four Speedtronic Mark II and 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 , the power plant could be operated and monitored from the central control room of the now decommissioned Ahrensfelde gas turbine power plant .
In 2008 the Thyrow power plant was in operation for around 350 hours per year. At that time it was "the only black-start capable gas turbine power plant" in the control area of the transmission system operator Vattenfall Europe Transmission (today 50Hertz Transmission ). Over the next ten years, the number of operating hours per year fell sharply, as did the amount of emissions ( see below ).
In June 2016, all blocks were reported to the Federal Network Agency for final shutdown. In the opinion of the transmission system operator 50Hertz Transmission , however, a permanent shutdown of the entire power plant would "with a sufficient degree of probability lead to a not inconsiderable risk or disruption to the security or reliability of the electricity supply system", which is why five blocks (A – E) were identified as systemically relevant. The Federal Network Agency also came to this assessment. The five gas turbines represent a black start reserve for the Jänschwalde power plant . Due to the classification as systemically relevant, it was ordered that the five turbines and the natural gas tube storage system should initially be kept operational for another two years, until mid-2018. The system-relevant reserve plants are not allowed to participate in the electricity market. Blocks A – E are still considered to be systemically relevant, their status is “legally prevented from being shut down” (as of 2019).
Other marketing options were sought for the remaining three gas turbines that were not systemically relevant. In 2017, Block F was dismantled and sold.
Capacity reserve
In February 2020, the five gas turbines A to E were awarded the capacity reserve tender by the transmission system operators for 150 megawatts. The reserve power must be provided from October 1, 2020 to September 30, 2022.
Natural gas storage
On October 29, 2010, an underground tube storage facility for storing natural gas was put into operation on the power plant site . The storage facility consists of tubes with a total length of 3.5 km and a diameter of 1.40 m and can store a working volume of natural gas of around 480,000 m³. The natural gas storage facility enables 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 built at the same time at the Ahrensfelde gas turbine power plant , totaled 33.5 million euros.
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 Thyrow substation .
Thyrow substation
Next to the Thyrow gas turbine power plant is the Thyrow substation (also called Thyrow substation ), which connects the 380/220 kV transmission network of 50Hertz Transmission with the 110 kV distribution network of E.DIS . The traction current converter station is also connected to the substation. A 380 kV line leads from the Thyrow substation to Ragow , as well as a 220 kV line to Wustermark , Berlin- Marzahn and Berlin- Wuhlheide .
Railway power converter plant
In 2004 and 2005, in addition to the Thyrow substation, a traction current converter station with a total output of 120 MW was commissioned by DB Energie GmbH . The facility was built by Areva . The converter plant consists of eight converters equipped with GTO thyristors , each with an output of 15 MW.
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.
