Altbach / Deizisau thermal power station
The Altbach / Deizisau thermal power station is a hard coal-fired power station in Baden-Württemberg . It consists of two blocks and stands on the Neckar near Esslingen in the districts of the communities Altbach and Deizisau , Württemberg.
The total installed electrical output, including the gas turbines and Combiblock 4, is around 837 MW. The power plant is connected to the 110 kV high voltage network of Netze BW and to the 380 kV high voltage network of Transnet BW .
history
Heinrich Mayer built his power center as early as 1899 , the first coal-fired power plant at the Altbach location. 1899 is therefore also the year the Neckarwerke was founded .
The forerunner of today's power station was built in the late 1940s. Unit 1 went into operation in 1950. Unit 2 and 3 followed in 1960, Unit 4 in 1971. Unit 1 was shut down in 1982 and demolished in 1985, the 120 meter high chimney was blown up. Blocks 2 and 3 were demolished in 1993 and the two 120 meter high chimneys were blown up.
Existing power plant units
Heating plant 1
HKW 1 went online in mid-1985. Originally this facility was called Block 5. The power plant initially had a gross electrical output of 420 MW el . By retrofitting the high and low pressure turbine in 2006, the electrical output could be increased to 433 MW el . The district heating extraction of 280 MW th remained unchanged.
HKW 1 feeds into the network of the transmission system operator Transnet BW at the 380 kV maximum voltage level .
The cooling tower in Unit 1 is a cooling tower with forced ventilation by fans, which can be operated either as a pure wet cooling tower or as a hybrid cooling tower. The cooling tower is 45 meters high and served as a prototype for the hybrid cooling tower of the Neckarwestheim 2 nuclear power plant . The chimney of HKW 1 has a height of 250 meters.
On February 27, 2017, the management board of EnBW announced that it wanted to shut down the block. EnBW wanted to finally shut down the block on March 31, 2020, the Federal Network Agency prohibited this and classified the system as systemically relevant by March 31, 2023. Only then can Unit 1 be finally shut down.
Thermal power station 2 with gas turbine E
HKW 2 started operating in 1997. It initially had a gross output of 336 MW el in the main boiler operation, with a net efficiency of 41.3%. A modernization in 2012 increased the output by 20 MW, to 350 MW el . Part of this modernization was a retrofit of the medium-pressure turbine, as well as a conversion of the furnace and the six coal mills . Hard coal or natural gas is used as fuel for the main boiler.
In addition, HKW 2 has a gas turbine (gas turbine E) with an output of 60 MW el and a waste heat boiler. The gas turbine E (Solo), like all gas turbines at the site, is classified as systemically relevant by the transmission system operator in the 2013 network development plan .
The electrical output in interconnected operation is 428 MW el with an efficiency of 43.8%. As in HKW 1, there is also the possibility of district heating extraction of 280 MW th in the main boiler operation, which can be increased by a further 87 MW th in interconnected operation with a waste heat boiler . The fuel efficiency is up to 80%.
HKW 2 feeds into the network of the transmission system operator Transnet BW at the 380 kV maximum voltage level, and the gas turbine E feeds into the network of the distribution network operator Netze BW at the 110 kV level .
The cooling tower of HKW 2 is the same type of cooling tower as HKW 1. The cooling tower is 42 meters high and has a base diameter of 76 meters. Like the neighboring HKW 1, HKW 2 also has a 250 meter high chimney.
Combination block 4 with gas turbine A
Block 4 went into operation in 1972. It has an upstream gas turbine (gas turbine A) of the Siemens V93.0 type with an output of 50 MW el and an oil / natural gas-fired main boiler with a steam turbine. There is also the option of channeling the exhaust gases from the gas turbine into the main boiler, which enables combined cycle operation . The electrical output is then 238 MW el , in the combined heat and power mode a maximum of 175 MW el and 180 MW th are possible.
The gas turbine A feeds on the 110 kV level into the network of the distribution network operator Netze BW .
The chimney on Block 4 has a mouth height of 150 meters.
Combined block 4 is in cold reserve , gas turbine A (Solo) is classified as systemically relevant in the network development plan.
Gas turbines B and C
The two gas turbines went into operation in 1974 and 1976 and have an electrical output of 60 or 87 MW and can be operated with either natural gas or EL heating oil.
Gas turbines B and C feed into the network of the distribution network operator Netze BW at 110 kV level and are also classified as systemically relevant.
operator
The operator is EnBW Kraftwerke AG; before that it was the Neckarwerke Stuttgart (1997–2003), until 1997 the Neckarwerke Elektrizitätsversorgung .
District heating supply
The power plant is connected to the Stuttgart-Gaisburg combined heat and power plant in Stuttgart-East and the Stuttgart-Münster waste-to-energy plant via a district heating line , the so-called Mittlere Neckarschiene . Most of the industrial operations in Esslingen and Stuttgart (including the Daimler AG plants ) are supplied with district heating, as are many private households in Esslingen, Altbach, Deizisau, Plochingen and Stuttgart.
Emissions
Both thermal power stations are equipped with efficient denitrification , dedusting and desulphurisation systems. The operator reported the following emissions in the European PRTR pollutant register :
