This report updates the previous basic reporting on three of the
major electric power plants in Szechwan Province, central China, using
1969 and 1970 photography. It also includes the initial basic report
on a fourth plant. The cut-off date for information is February 1971.
No changes were observed at the Cheng-tu Heat and Thermal Power
Plant and the Chung-ching Thermal Power Plant 507. Both plants were
operating on the latest coverage.
Nei-chiang Thermal Power Plant Pai-ma-miao has not been seen on
interpretable photography since the previous report.
Chiang-yu Thermal Power Plant was partially complete when it was first
observed in August 1965. By November 1968, the most recent good-quality
coverage, major additions had been constructed. At that time the plant
contained two boilerhouses, two generator hall sections, two stacks, a
switching yard, a control house, a coal storage and processing facility,
and a nearby water intake and treatment facility. The plant was operat-
ing when it was last seen in August 1969.

Chiang-yu Thermal Power Plant is located about 5 nm south of Chiang-yu,
China. It is served by road and rail.
On the most recent good-quality photography of this plant in November
1968, it consisted of two boilerhouses, two generator hall sections, one
small and one large stack, a switching yard, a control house, and a coal
storage and processing facility. A water intake and treatment facility,
located I nm to the southwest, is connected to the plant by a buried
pipeline. The small boilerhouse contains two boilers and the large
boilerhouse contains at least three boilers. The position of the large
masonry stack in relation to the large boilerhouse indicates that it
could be expanded.
The western section of the plant appeared complete when the plant
was first observed on photography of August 1965. It consisted of one
boilerhouse with two boiler units and a generator hall section, a small
stack, a switching yard, a control house, and a coal storage and processing
facility. Large additions were being constructed at the eastern ends of
the boilerhouse, generator hall section, and switching yard. A second
(large) masonry stack was also under construction.
Poor-quality coverage of November 1966 and January 1967 precluded an
analysis of construction progress on the additions to the plant. In
November 1968, the large boilerhouse with at least three boiler units and
the generator hall sections were observed completed. Only the two stacks
and the coal storage and processing facility were discernible on poor-quality
photography of August 1969. It was not possible to determine if any changes
had occurred at the plant since November 1968.
The plant was operating in November 1966 and August 1969 as indicated
by heavy smoke coming from the large masonry stack. This probably indicates
that at least one of the boilers in the large boilerhouses was operational
as early as November 1966. The plant did not appear to be operating in
August 1965, January 1967, and November 1968.
