Nancho Hydropower Project implementation commences in Nay Pyi Taw Pyinmana






At present, the Ministry of Electric Power No. 1 is implementing medium and large scale hydropower projects as the renewable energy throughout the nation. In accord with the guidance of Head of State Senior General Than Shwe to generate electricity through hydropower in the country, the Special Projects Implementation Committee of the State Peace and Development Council approved the implementation of the Nancho Hydropower Project at its meeting 1/2006 on 22-9- 2006. The project is being implemented by the Con
hydropower projects as the renewable energy throughout the nation. In accord with the guidance of Head of State Senior General Than Shwe to generate electricity through hydropower in the country, the Special Projects Implementation Committee of the State Peace and Development Council approved the implementation of the Nancho Hydropower Project at its meeting 1/2006 on 22-9- 2006.
The project is being implemented by the Construction- 1 of the Ministry of Electric Power No. 1 on Nancho Creek, 16 miles east of Nay Pyi Taw Pyinmana and 12 miles upstream of Paunglaung Hydropower Station that
is generating 280 megawatts. Nancho Creek flows into Paunglaung River. Construction of the hydropower plant at seven miles upstream of the confluence of Paunglaung River and Nancho Creek will not slow down the
flow of water in Nancho Creek and can contribute to the storage of water that flows into Nancho Creek in the rainy season for generating hydroelectricity. There are 65 inches of rainfall annually and 1024 cubic foot-second of water flow in the environs of Nancho Creek. The cheek has 317 square miles of watershed areas, and a total of 767,110 acre-foot of water flows into the creek. The water will be stored with the 443 feet long and 167 feet high CVC (Overflow Type) concrete embankment. Moreover, the surplus water will be released
from the 349 feet wide overflow type spillway. To use electricity at the project site, a smallscale hydropower plant was constructed at Hsaungtaung Creek by generating 60 kilowatts. On completion, the water from the dam will be supplied to the 269 feet long and 79 feet wide water control lake from the concrete type intake structure installed with 49 feet wide and 73 feet high sluice gate through the intake channel that measures
7330 feet by 15.5 feet. Two turbines will be run with the use of water from the water control lake through the 13 feet diameter and 876 feet long prestressed steel pipeline. Nancho Hydropower Plant installed with two
20-megawatt vertical Francis type turbines will generate 40 megawatts to be connected with the national
power grid through a switch yard. To conserve the environmental beauties, the dam of Nancho Hydropower Plant will be of the CVC (Overflow Type) concrete embankment, but not the Rockfilled Dam with Earthcore
or RCC Dam (Roller Compacted Concrete Dam). Salu Creek is located between the intake structure and the water control lake. As part of environmental conservation, two intake tunnels that measure 7,330 feet by
15.5 feet each will be connected with a 15.5 feet diameter and 384 feet long aqueduct to avoid blocking
the creek. The aqueduct on a bridge will be passed over the creek, and the bridge will be constructed with two concrete posts in the creek. At present, the temporary embankment and diversion conduit are under
construction. Soon, the water of Nancho Creek will be diverted for the project. The hydropower project will be completed in the year of 2010. Upon completion, the power plant can supply 152 million kilowatt
hours on average yearly to serve the interest of the national people.
