Venezuela’s second massive power outage of the year plunged much of the nation into darkness on Monday night, prompting renewed talk of sabotage from President Nicolas Maduro’s government and cries of incompetence from its foes. Power went off in Caracas and other cities around the country soon after 8 p.m. local time, to the intense annoyance of residents and commuters. “I feel so frustrated, angry and impotent,” said sales adviser Aneudys Acosta, 29, trudging through the rain along a street in the capital after having to leave the disrupted underground transport system. “I live far away and here I am stuck under the rain. Something’s going wrong that they’re not sorting out. The government needs a Plan B. This is just not normal.” Monday’s outage appeared similar to a massive Sept. 5 blackout that was one of the worst in the country’s history.
