Renovation
of Small Hydropower Plants by Hydropower Construction
Division in 2005 |
| |
EGAT
was approved by The National Economic and Social Development
Board (NESDB) to renovate five small Hydropower Plants
in a budget of 1,837.16 million Baht. The approved budget
for the project consists of both local loan currencies
and EGAT's revenue. The project benefit/cost analysis
was assessed and it could be concluded from the study
that the project is technically and economically feasible.
The energy from the five small Hydropower Plants is
an important replacement energy since it can reduce
the imported oil and natural gas from overseas for energy
production. Furthermore, the project can increase the
operating efficiency of five small Hydropower Plants
due to operated for more than 30 years. The five small
Hydropower Plants are:

1.
Ubol Ratana Hydropower Plant The
Power Plant is located at Ubol Ratana dam. The dam
is located on the Nam-Pong river, Tambon Kok-Soong
, Amphur Ubol Ratana, approximately 50 km. north
of the city of Khon-Kaen province. The dam is a
multipurpose dam for development of electricity,
irrigation for agriculture (approximately 302,000
Rai), flood control,, transportation, fisheries
and tourist spot. The dam is an earth core rockfill
dam and was constructed in 1984. The Catchment Area
is 12,000 km2, Normal Flood Level is 182.00 m (MSL),
Maximum Storage Capacity is 2,559 million M3. The
total installed capacity of turbine and generators
is 3 units of 8,400 KW each and annual energy production
is 57 Gwh. The operation of the 3 units was started
on February 4, 1966, March 14, 1996 and June 12,
1968 respectively. The 3 units have been operated
for about 38 years. |
