"It's difficult as winds and waves are huge in the north," Lin said.
Natural gas demand is expected to rise to 9.5 million tons this year from 8.3 million tons in 2007, and may reach 16 million tons in 2020, CPC Chairman Wenent Pan said in February. The capacity of Yongan, the island's only LNG port, can be expanded to 10 million tons, Lin said in December last year.
"Yongan will be enough to handle demand," Lin said yesterday. This year's gas consumption may be less than forecast as electricity use falls, he said.
Power consumption declined 6 percent from a year earlier last month after Taiwan Power Co., the island's only electricity retailer, raised prices. The Taipei-based utility increased tariffs by 12.6 percent in July.
About 80 percent of Taiwan's LNG is taken up by power producers, according to the Bureau of Energy Web site.
Gas fired generators accounted for 33 percent of the island's installed capacity as of June, Taiwan Power said on its Web site. Construction of the utility's Tatan plant in northern Taiwan is scheduled to be completed by January.
LNG is natural gas that has been chilled to liquid form, reducing it to one-six-hundredth of its original volume at minus 161 degrees Celsius (minus 259 Fahrenheit), for transportation by ship to destinations not connected by pipeline. On arrival, it is turned back into gas for distribution to power plants, factories and households.
