Blackout hits much of Venezuela

A blackout hit a large swath of Venezuela on Thursday, darkening street lights, shutting down the Caracas subway and forcing President Hugo Chavez's government to resort to temporary rationing measures. The power outage affected the capital of Caracas and 12 states stretching across the northern half of the country, Electricity Minister Ali Rodriguez said.
The state oil company said some activities were interrupted at its refineries, including units partially halted at the Jose heavy crude upgrading complex in eastern Venezuela. But it said operations were expected to be back to normal by early Friday. A forest fire apparently caused the outage by overheating major transmission lines in western Venezuela and knocking them offline, Rodriguez said. He said that failure forced various power plants to shut down and caused a cumulative drop of about 10,000 megawatts, a large share of the country's generating capacity of roughly 24,000 megawatts.
Rodriguez told state television Thursday night that power had been completely restored throughout the country about two hours after the outage began. He said it had been a power loss of ``enormous size.'
Vice President Elias Jaua vowed a thorough investigation of the causes of the forest fire. He said it was unclear how the fire started but that ``we never stop investigating situations of possible sabotage.' He suggested sabotage wouldn't be beyond some hard-line opponents of Chavez, saying Venezuela has ``extremist sectors that still don't accept the democratic game.'
Various power plants were being gradually restarted after the blackout, Rodriguez said. He said that power would be rationed during a three-hour period during the night and that some areas would see rolling blackouts lasting 20 minutes or less. ``It will be temporary,' Rodriguez said.
In Caracas, the outage forced subway stations to close in the afternoon, and some passengers had to be evacuated from stranded trains. Stoplights were out in some places, and heavy traffic jams filled the streets. Venezuelans in many parts of the country had to cope with rolling blackouts for months last year, when Chavez's government said cutbacks were necessary during a drought that drove water levels to precarious lows in the dam that supplies much of the country's power. Chavez lifted those rationing measures in June. Opponents accuse the government of failing to invest enough in new electrical projects to keep up with growing demand.
