CAP#CITr EUAKWION Or EAST GERMAN POWER PLAITS
50X1-HUM
1. At present, the East German power industry has an operable capacity of
3,000 megawatts and an installed capacity of about 4,500 megawatts. Last year
(1954], an installed capacity (increase] of 685 megawatts was planned; actually,
only 550 megawatts were installed. The plans mention an operable capacity of
480 megawatts. In 1955, 626 megawatts are planned to be added to the power net,
300 megawatts of which are }lenned for the first half of 1955. Of this latter
amount, 195 megawatts are to be put in continuous service. It was originally in-
tended to start replacing all power plants producing power at a cost of more than
0.10 DH per kilowatt-hair with plants producing power et R cost of up to .50 DM
per ki lcwntt hour. Subsequently, this plan was withdrawn, since it would exert
too great a drag on a continuing production of the industry.
2. The viewpoint has been adopted that to improve efficiency in condensing
plants, it is necessary to change over to higher pressures and temperatures and
to utilize larger machinery units.
3. The Elbe Power Plant at Vockerode is at present the most modern condensing
plant in East Germany, possessing boilers with a capacity of 160 tons per hour,
84 atmosphere allowable gauge pressure, and 500 degrees centigrade, and 32-megawatt
turbosets.
4. Installations of 132 atmoapheas gauge pressure and 75-megawatt, double-
tLaft turbosets are already under constriction. In 1956, attempts will be made
to construct installations of 20C atmospheres maximum gauge pressure. To do s:,
however, the tluSR will have to supply L..,: necessary technical data. The purpose
of these attempts is to reduce considerably the coal consumption for the power
produced.
5. Long-range power plans further call for the construction of heat and
power plants with an installed capacity of 300 megawatts by 1960, plus better
utilization of power and heat.
6. In addition, it is hoped to set up a 1,100-kil(meter, 220 kilovolt
consolidated veil-grainded net. Czechoslovakia has supplied the ,.echnical
data for this plan. Tc? the degree that the building of the 220-kilovolt
net proceeds, the 110-kilc"'lt consolidated nets will be red:irr'd to the level
of Bezirk distribution nets while the local nets (Ortsnetze) viii be built
only as four-line, three-phase current nets of 220/380 volts.
7. At the same time, it is hoped to convert by 196o the existing one-phase
and two pLase alternttinu-cur.-ant n^tr. anA the 12'(/9t'-vnit three-phase nets.
At ?- -'. there is a 220-kilovolt long-distance line between Magdeburg, Wit-
tenberg, and Guestrow, as well as a 110-kilovolt line between Pasevalk, Fuers-
t.'rticrg? and Granese. Work is being done currently on the line between Tratten-
dorf and Berlin; sbhortagesof materials are causing difficulty., particularly in
xeeid of sapebcillh or~iaporrttaanncento the and rthe northeast paarrtsof
""t crm .
8. In Bezirk Rostock it is planned to increase the capacity of the Peene-
nuende Power Punt to 120 megawatts. One 60-oegavatt turbine has already been
installed in the plant. The Bramo-Rostock Power Plant has a capacity of 55 meg-
awatts; the Stralsund Power Plant,12 megawatts; and the Wolgast Power Plant, two
2.5-megaatt units.

9. The VEB Power Supply Enterprise in Erfurt (at Meister-Eckehard Strasse)
is responsible for the area of south and west Thueringen and includes about 1,050
localities. The etr.erprisc'u output equals 135 megawatts; the most important parer
plants included in the enterprise are Erfurt I with 25 megawatts, Fsturt II-
Gisperaleben with 25 megawatts, and th.. V M Bleicherode Potash Works with 0.6 meg-
awatt. The capacity of the lait-named power plant is to bn raised to 8 megawatts
In 195; although this is greatly dependent on th. "Gabelverbindung" [forked connector?).
10. There is a 100-kilovolt feedline (Einspcisuug) between?Groaskayna and
Oberroeblingen over which about 20 megawatts can be transmitted.
11. A 100-kilovolt line links the Breitungen Power Plant sear Suhl with
Erfurt and Jena. A 30-kilovolt line leads directly to Eisenach with a second
30-kilovolt li...? to Eisenach via Gotha.
12. The Erfurt-Gispersleben transformer nubatation is linked with Arnstadt,
langeviesen, Weimar, Apolda, and Soemmeria by n y?-kilovolt line. These lines
are double lines (doppelt besetzt). Although normally 350-volt three-phase current
is carried, the local nets (Ortsnetze) for the most part still carry 220 volts.
13. The main power inspection office (Hauptenergie-Inspektion) and the main
load distribut'on office (Hauptlastverteilung) for all East Germany is located in
the Berlin-8riedrichafolde transformer station on Marsahner Chaussee.
14. The following power plants are responsible for supplying power to Bezirk
Halle: Zachornevitz, Elbe-Vockerode, Groaskayna, Karl Liebknecht, and Breitacheid,
as well an the Deeaau, Klostermannsfeld, Zeitz, and C,uadlinburg net enterprises
(Ratzetriebe), plus the Bueschdorf repair plant.
15. By the end of 1955, the Zschorns:itz Power Plant is to obtain the
following air comprcasor installation for 100 kilovolt-house (Haus), 100
kilovolt-regulating cell (Schaltzelle), dividing walls (Trennvaende), one
set of tubular coolers for a high-voltage transformer, two cathode arresters

chain conveyer (Schreegbandkette). In addition, general repairs are to be made on
the two cooling towers, on boilers F, to F12, on the superheater for boilers E5
and E7, and on the 100-kilovolt transformer. There are to be new pipes in the
condenser of unit 9, replacem'snt of live-steam heating with dry-steam heating in
the alevatrr' 1"+rker (llochbunker), replacement of the condenser-pipe channels

great per kilowatt hour. In addition, plans call for rebuilding boiler 7 to
achieve an increase in output, a partial blading (Tei.lbeschafelung) of turbine
I to reattain the rated capacity, and introduction of the four-shift system in
coal unloading.

17. The Oresskayna Power Plant is to improve the treatment of boiler feed
water and to obtain new measuring ad regulating equipment, a new degassing
installation (fatpsuag ) for throw '7enson' boilers j e g a pneumatic ash-removal
inrtallatioa; turbine 6 and Denson boiler. 1 and 2, including the measuring
and regulating equipment, are to be overhauled.
18. In boilerhouse I of the Karl Liebknecht Power Plant, the uptake (Fuchs)
at boilers 11-18 is to be linked with the uptake of boilers 19--24 to increase
the steam o tyut by 8 tons per hour. There vill also be repair of the 50/12-
atraspberes-pup reducing station, improvement is the vacua, of unit IV, new
steam jets in unit V. construction of a superheated steam cooler in the super-
beated?steam pipeline (Iaitung) of unit VI, and introduction of a means of
separating unit VI from the cooling net. Unit VI is limited in regard to the
temperature of the live stews it delivers. The unit operates as a bleeder
steam-eoadensing ?init together with the new back-pressure unit VII in dcliver-
iog live steam to a pet. Because of the temperature limitation of unit VI, an
additional increase (operationally possible) of the steam temperature to the
rated value of unit VII is not possible. '!'his means, therefore, an output loss
for unit VII. It is planned to install a superheated steam cooling system in
the ducts of unit VI, so that then the boiler will be able to drive unit VII
with a higher output temperature and the branch. duct to unit VI will be cooled
to the rated temperature. Since units'VI and VIII share a common water cooling
pipe with no intermediate separation, taking otc unit VI for overhaul also
means that unit VIII has to be cut off from the net, or else the condenser of
unit VI will not be free of water. It is planned to install a cooling water
cover plate at the intake of the unit VZ condenser, so there will not be a
lose in output with the subsequent removal of unit VIII.
19. The Dessau net enterprise (Netzbetrieb receives power from the Alton
Power Plant. The following is planned for 1955: construction of a new rust-
protective cover for boiler II, thereby assuring the power and steam output
with the high-ballast content (ballaatreich) coal already delivered which has
a calorific value of 2,200 kilocalories; general repairs to one turbine, to
the condensation ducts and tank, end to two plant care at VEB Zoerbig Rail-
road Car Plant; rerouting of a 15-kilovolt cable from the "West" substation
via Elisabeth/Stift strasse cold-storage plant (Kuehlhaus) to supply power to
the cold-storage plant in Dessau; construction of a 15/5-kilovolt switch and
transformer building in Dessau-Waldersee (Ziegeleistrasse) for improvement in
the supply of power to the area of Waldernee/Mildensee; construction of a 15-
kilovolt line in Durow-Cosvig making possible an increased and sufficient sup-
ply of about 15 megawatts to the VEB Cosvig Paper and Corrugated Cardboard
Plant; and converting the direct-current secondary net (Teilnetz) in Koethen,
Schmeideberg, and Aken to alternating current.
20. The Zeitz net enterprise obtains power from the Weissenfels, Zeits,
and Uumburg power plants, and delivers steam to the Weissenfels and Zeits po-
wer plants. The 1955 p?wn calls for the following: providing three belt con-
veyers and a powerhouse crane to the Weiseenfels power plant; providing an
electtic-drive centrifugal pump as a second feeding installation to the boiler
units for the Zeits power plant (inasmuch as the completely antiquated duplex
pumps are very ptode to breakdowns); rerouting of a secOhd feeder cable in Na=-
burg; construction of a transformer station in Grosswiladorf; installation of
a compensating unit in the converter installation of plant II of VEB 7eitz, so
that in the event of a disruption of the 7a itz Paver Plant about 300 kilowatts
can be fed into the direct-current net and thereby assure a supply of pcver to
the most vital enterprises; and construction of a long-distapce, high-speed
(Schnelldistanz) relay in the Theissen transformer works for increased protec-
tion of the 15- and 35-kilovolt feed-ins and to reduce the disruption effect
upon the Theissen paver plant.
21. Concerning the Quedlinburg net enterprise, the toilaring is planned;
construction of a ne?r trausforuer station it, Bernburg-Wasserturat; conatrtction
of a traasfoz'aer station in Sernburg (I.indenplatz); conversion to three-phase
currant; conatructicn of a transformer station in Ballenstedt; replacennt.of
the 1t-kilovolt svi'ch (Schalter) in the Quedlinburg Power plant,,aince the oil
switches (Oelscbalts c) are no longer usable; rerouting of the 15-kilovolt cable
in the Bernburg locel net (Ortsnetz) to link up with the new Lindenplatz trans-
f r station when it is finished; conversion to three-phase current in Qued-
g/Suederstadt; and "Fe" (front) replacement in the medium-voltage and
1 *1 Gets.
22. Individual power manta
a. On 28 June 1955, test operation of the 50-megawatt turbine in the
Eirschfelde power plant began. However, because of damage to the cover
(Dsckelscbedee), operation has since been halted. The Hirechfelde Power Plant
and the alsterberg Power Plant, located south of Greitz, deliver power tc Czech-
oslovakia. On the other hand, the Pirna Power Plant receives low-temperature
coke from Czechoslovakia. At the Stalinstadt Power Plant the third boiler heated
with tlast-furnace gas has been put in operation. At the Dune Power Plant 20 meg-
awatts have been put Into teat operation, and at the VEB Zeitz Hydrogenation Plant,
10 megawatts. At the Mzldensteln railway power plant the first turbine is now
operating. A gam pipeline has been lrid by the lauchhammer and Groednitz power
pl..nt with 30 etmo-?l'-^"+ gauge: the pipe has a diameter of 400 millimeters and

three turbines ton the Voith company, vhile the, pressure pipe 14 to be delivered
by the Man comy;Any in Augsburg. Three 50-megawutt topiind turbines are planned
for the Zschornewitz power plant.
b. The main departruent for Dover slant inutallt.iors (liau;tebtelluab
Kraftwer:tsanlagen) has an allotment of 65 million DM for 1956. Ircluued aI. his
are various projects already begun, such as six power plants for Chicu, seven
power ylart installations for Poland. fo'ir industrial power plants for a sugar
factory in Rumania, a sugar factory in Indonesia, and two textile lants it Turkey.
Concerning the .'.50-megawatt Polish power plant in Konin, Eest Germany will sul,ply
only the boilers, while Czechoslovakia will .apply the t.uroines. In addlt on,
power plants are to be extublished in Stettin (Szcz..cin), Wursav, ar:d ,u3chwitz
(Oswiecim).
c. There In a gen_ral storage of electronic regulating equipment. At

Output of turbines when fully utilized will be 25,000 kilowatt-hours.
Boilers will have a capacity of 125 tons of steam per hour. Trattendorf II,
"Schwarz* Ptape", will be equipped with back-pressure turbines. Trattendorf
III, located vast of the Spree River near Spreaberg, will be equipped with
high-pressure and low-pressrare turbines (Vow-und llaohscbaltturbinen).
Preliminary construction work is now being carried out for Trattendorf
II,'eni for the coking plant. So far, Trattendort III has only roe 25-megawatt
turbine. A second turbine was supposed to start its trial run an 30 June 1955,
but still has not been put in operation. At Trattendorf III all cable hob to be
relaid because it has been heavily dameged by nails. Turbines III and IV are
supposed to be installed this year (1955(. Preliminary work for the construction
of the auxiliary machinery building has not yet been concluded. Moreover, there
is a shortage of 1,500 workers needed for the construction of Trattendorf I.
Work has also started on the construction of a 220,000-volt line between
Trattendorf and Berlin; the line will be 130 kilometers long. Most of the power
produced at Trattendort will be transmitted over this line to Berlin and to the
area north of Berlin. According to plane, the line to ba completed in 31 Decem-
ber of this year. Hoveier, difficulties are being encountered in the producesion
of the approximately 400 towers and the cable required for this line. The Mesa
Steel and Rolling Mill is not supplying enough angle iron for the towers and the
Wire and Cable Works in Rothanburg 1s behind in its deliveries of cables; moreover,
the Frankfurt/Oder Construction Union so far has not started laying the foundation
for the Berlin-Oat transformer station, and as a result the VEB Berlin Installation
Construction Plant (Anlagenbau) cannot start assembling equipment.
Trattendorf will receive its coal supply from the John Schehr Brown-Coal
Works in Laubusch. In 1957, the new Bluno open-pit mine will start supplying
coal to Trattendorf. According to plans, 12 million cubic meters of over-
burden are to be removed in 1957. To achieve this goal, the Finkerherd and
Skado brown-coal works have made their conveyers available to the Bluno mine.
However, it is not expected that the planned raw-brown-cc:al production of 6 million
tons yearly will be achieved at the Bluno mine before 1958. The Bluno mine will
also supply the raw coal for the coking plant planned for construction in Tratten-
dorf.
"SON1E" AND Li+t1TA POWER PLANTS
('ncloaure R, dates cl July 195;;)
The "Sonne" Power Plant is being specially expanded for the brown-coal
industry. At the end of 1954, equipment with capacities totaling 20 megawatts
was undergoing test runs at the "Sonne" plant. '!tio 8-megawatt units are sup-
posed to be added this year (1955). The power plant has also received 14 now
crushing mills.
The Lauta Paver Plant is being expanded to supply the aluminum irAustry
which is to be established in this area. At the end of 1954, the Lauta plant had
an installed capacity of 83 megawatt. Actual producticn was 500 million kilowatt-
hours. According to plans, the plant . capacity is to be increased to 133 megawatts
thib year by the installation of four 12.5-megawatt units. It will then.be able to
produce 930 million kilowatt-hours !annually). Lix new boilers have been assembled.

the desisasrs decided on a boiler working pressure of 80 atmospheres pup at
50 degrees centigrade, which results at the turbines is a kick-oft pressure of
71 atmospheres absolute at about 50 degrees centigrade. Moreover, it was de-
cided to add a third group or three turbosets to the first two groups, each of
which also consists of three turborets. Each turbosst has a capacity of 32
nepw.,%tts. According to plane, the sixth of the ulna planned turbines is to
be assembled and connected to the network by the end of this year (1955]. This
turbine. w we delivered by VIN Eerpann-3orsig in Berlin on 27 June 1955. Accord-
ing to plane, a total of three 32-megawatt turbines are to be installed in the
plant in 1955. The plant's fifth turbine was assea'oled on 24 Jane 1955. On 3
My 1955, the plant received a superheated steam cooler Eras VED Karl Llebknecht
(Dsavy machinery] Plant in Magdeburg; the same enterprise is producing four
boilers for the power plant.
Pleas call for increasing the proportion of warren workers at the plant
tram 11.6 to 12.2 percent.
The raw brown coal used at the power plant has a calorific value of about
2,000 kilocalories per kilogram; it is transported to the plant from the Gulps
and'Dergwits open-pit sines and fro the new Muldeastein wine by a standard-
gaup railroad.
Located !.n front of the poor plant is the 6-kilovolt installation, sepa-
rated by a read from the 110-kilovolt installation which is located further
south. The two installations are connected by a switching installation, bridg-
ing the. The electric power produced is transmitted into the network (Landes-
natz) by way of the 110-kilovolt installation. For the rlant's own power re-
4uinvments (Eipnbedarf) the high-voltage current is fed back into two separate
6-kilovolt min distribution installations (Eigenbedarfahauptverteilungen). Di.-
Pact reserve feeding of generators 2 and 3 is provided for in the first construc-
tion-unit. The turbosets are located against the boiler house wall so that
each boiler (160 tons per hour) can be connected with its appropriate 32-Mega-
watt turbosst by block switching.
The radiation boilers for the power plant were developed in collaboration
with VEB Karl Liebknecht Plant in Wgdsburg-Buckau~ this enterprise has designed
and built a water-tube radiation boiler (Zweizugwasserrohretrahlungsksssel) with
a maxims capacity of 160 tons of steam per hour at a permissible pressure of
84 atmospheres gauge, a working pressure of 80 atmospheres gauge, and a super-
heated steam temperature of 500 degrees-centigrade. The normal load of the
boiler is about 135 tons per hour.
The turbosets, which are being produced by VEB Bergmannrsig, are twin-
housing condensing turbosets with capacities of 32 megawatts at 3,000 rpm with
directly coupled 140-megavolt-ampere generators. The live-steam pressure at the
quick-closing valve is 71 atmospheres absolute at a superheated steam tempera-
ture of 485 degrees centigrade. The turbine.% are designed for river water and
a back-pressure of 0.04 atmosphere absolute. 21e high-pressure turbine consists
of a double-rim act'nn wheel with a diameter of 1,200.millimeters, nine singlw-
rim wheels with a diameter -3f 900 a'llimeters, and four single-rim wheels which
have a disaster of iris! 1,200 to 1,350 millimeters. The separately housed low-
pressure section is constructed as a double-current turbine (Doppelstroaturbine),
with three single-rim wheels attached on each of both sides of the medium inlet.
