1. SUMMARY. Taipower Co. operates the Tatan complex which
will consist of six LNG-fueled units generating power from
gas/steam turbines. Two of the units are currently
operational with the remainder scheduled for completion in
2008. When complete the complex is expected to produce 10
percent of Taiwan's power needs. The project has lately been
faced with environmental issues related to algae reefs
offshore where some of the gas pipelines are being installed.
Wind-power units on site are subject to seasonal winds. END
SUMMARY
THE MOST EFFICIENT GAS-FIRED POWER PLANT
----------------------------------------
2. AIT ESTH officer visited Tatan power plant complex on May
9, located on Taiwan's Northeast coast. He also observed
some of the wind-power installations. Tatan was conceived as
a backup to the fourth Nuclear Power Plant (NPP) which has
been scheduled for completion in 2009. (note: AIT industry
sources suggest that date is very optimistic and a more
realistic date is 2010 or possibly 2011. End note). The
Tatan complex will be fueled with LNG imported from Qatar
through an arrangement with Exxon/Mobil (reftel). A total of
six combined-cycle gas units are planned with the final unit
to become operational in late 2008. Total electricity
generated from the six units will be 4,384 MW. Currently,
two mixed-fuel units are operating using both distilled oil
and LNG. When the remaining four units are completed, they
will have an efficiency of 51.65 percent, making it the most
efficient gas-turbines in the whole island. The LNG will
arrive by ship in Taichung harbor and then travel by
pipeline, now under construction by China Petroleum
Corporation (CPC) to Tatan.
AN INCOMPLETE EIS THREATENS ALGAE REEFS
---------------------------------------
3. (SBU) Environmentalists claim that the pipeline from
Taichung to Taoyuan (Tatan) will threaten offshore algae
reefs that have taken thousands of years to form. The gas
pipeline as designed will be built over algae reefs that
occur in abundance off the Taoyuan County coast where the
powerplant is sited. The reefs provide structural support
for the pipelines that a soft sandy bottom cannot. In 2005,
Taiwan Environmental Protection Agency (TEPA) approved an
Environmental Impact Statement (EIS) for the pipeline
construction. However evidence of potential damage to algae
reefs surfaced after the EIS approval. TEPA acknowledged to
AIT that although they have asked Taipower and CPC to come up
with protection measures by the end of May,l essentially they
cannot demand drastic measures because they approved the EIS
earlier.
WIND POWER: HIGH COST - LOW RETURNS
-----------------------------------
4. ESTH officer also visited a cluster of three
wind-turbines next to Tatan (23 units are currently operating
along the coast in Tatan with a capacity of 34.5 MW). These
units, supplied by GE at a cost of $3 million/unit were idle
because the turbines only kick-in when the wind speed reaches
4 meters/sec and stop when it reaches 25 meters/sec.
Taipower officials stated that Winter was the best season for
operating the wind turbines when winds average 5-6
meters/sec. This limits their peak operational time to six
months. Taipower officials complained of the difficulty
maintaining the 164-foot tall windmills (maintenance is
through a single stairway to the top) while the power
generated was small compared with conventional coal/gas fired
turbines. However, Taiwan's overall energy plan calls for
installation of enough units to generate 10 percent of
Taiwan's energy needs by 2010. If this goal is realized,
windpower would account for 80 percent of renewable energy.
Out of 546 windmills (with a total capacity of 1,980 MW)
planned for construction between 2010 to 2020, 176 will be
installed off the Penghu islands (located in the Taiwan
Straits) and the electricity relayed to Taiwan via a 40 km
undersea cable. The other 376 units will be installed along
the coast of Changhua and Yunlin counties in central Taiwan.
