"The system is 30 years old and a failure of this kind has never occurred," Electricity Minister Jesse Chacon, as the government continued to suggest that sabotage was behind the power cut.
Maduro blamed the three hour outage Monday night on what he said were "conspiracies" ahead of the country's December 8 municipal elections.
"There are attacks on the electricity service to disconnect it for days," he said. "They aren't going to make us suspend the elections."
Opposition leader Henrique Capriles derided the government's explanations as "pathetic."
"For once in your life be responsible," he wrote on his Twitter account.
Electrical engineer Jose Manuel Aller told AFP that the government's explanation was dubious.
"Just before the blackout there was an oscillation in the network, which generally occurs when transmission limits are exceeded, causing a failure that activates the security systems," he said.
He said transmission lines were long and vulnerable to a "weather event, rain, lightning or a storm."
He also noted that the government had sent troops to protect the electrical system after a similar outage in the same place in September.
"It would be very difficult for someone to gain access to the system," he said.
Maduro, a former union leader and bus driver, is struggling to establish the stature and following enjoyed by his political mentor Chavez, who died of cancer in March.
The December 8 municipal elections are considered a test of Maduro's popularity and performance since taking power
Chacon said the outage hit the metropolitan Caracas region and states in central and western Venezuela.
He said it started in the same place where a blackout in September left 70 percent of the country without power for at least three hours.
Then, too, the leftist Maduro blamed his political opponents.
State-run oil company Petroleos de Venezuela said its facilities were operating normally.
In Caracas, cars drove through darkened streets. Only hotels and other buildings with emergency generators had some light.
In 2010 Chavez imposed severe electricity rationing because of what he called problems with Venezuela's main hydroelectric dam and wasteful use of energy.
In April, Maduro declared another electricity emergency and extended it in August for another 90 days, even though he said the sector had improved considerably.
Monday's power outage struck at around 8:10 pm (0040 GMT). Power began being restored less than an hour later.
Despite being one of the world's largest oil producers, Venezuela is regularly affected by power cuts.
