Pyongyang Heat and Thermal Power Plant was first seen on photography of
December 1962 when it was in the very early stage of construction. Work on
the plant continued steadily until it was observed complete in August 1969.
The major plant facilities include two boilerhouse sections with a total of
10 boiler units, a large generator hall, and a large switching yard with
11 main and five auxiliary transformers.
Steam seen coming from a boilerhouse section roof in January 1965
indicated that the single boiler unit completed at that time may have been
operating. Since that time the plant has been seen operating on all photo-
graphy through January 1971.
This report includes a photograph of the plant and a chronological
summary of construction and operational status.

Pyongyang Heat and Thermal Power Plant is located in the southwest section
of the city of Pyongyang (see Figure 1).
Physical Features
The plant is surrounded by a moat and occupies an area measuring approxi-
mately 2,100 by 1,600 feet. It is served by both rail and road.
Construction Chronology
The plant. was in the early stage of construction when it was first seen
on overhead photography in December 1962. At that time, the water pumphouse
and the water treatment facility were under construction, and footings were
observed for the northern boilerhouse section, the generator hall, the control
house, and the switching yard. By January 1965, one boiler unit in the
northern boilerhouse section, part of the generator hall, the control house,
the water treatment facility, the switching yard, the coal handling facilities,
and the stand-by fuel storage area appeared to be complete. Five additional
boiler units were seen under construction for the first time in the northern
boilerhouse section.
Between January 1965 and November 1966, the northern boilerhouse section
and the coal preparation building were completed, and the generator hall had
been expanded. Approximately half of the southern boilerhouse section and
its associated stack were also seen externally complete on the November 1966
photography. In addition, expansion was noted at the switching yard, but it
was impossible to determine the number of transformers installed in either
the original or expanded sections of the yard.
On photography of February 1968, six transformers were observed in the
original section of the switching yard, and four transformers were seen
in the expanded section, which appeared complete. Three boiler units were
observed installed and a fourth boiler unit was under construction in the
southern boilerhouse section at this time. This fourth boiler unit was
completed between February 1968 and August 1969. During this period, a
fifth circuit was added between the generator hall and a circuit support
at the southern transformer position, but no transformer could be seen.
In October 1969, this transformer was seen in place, making a total of
11 main transformers observed at the plant to date (see Figure 2). With
the exception of five auxiliary transformers identified on subsequent
good-quality photography, no changes were observed at the plant from October
1969 to January 1971.

Operational Status
Smoke seen coming from one of the roof vents of the northern boilerhouse
section in January 1965 indicated the single completed boiler unit may have
been operating. The plant was operating in November 1966. At that time, the
northern boilerhouse section contained six completed boiler units. Heavy
smoke coming from the northern stack indicated that any or all of these six
units could have Been operating. Both stacks were seen smoking on the February
1968, August and October 1969, and January 1971 photography. Any or all of
the 9 completed boiler units could have been operating in February 1968, and
up to ten units could have been operating on the remaining coverages.
