Downtown Harare was hit by widespread outages minutes before state-run radio and television were scheduled to broadcast Mugabe's speech live from Parliament. The television station ran cartoons until power was restored about half an hour into the traditionally hour-long speech.
Mugabe promised to reinvigorate a program aimed at identifying new energy sources, including extracting oil from coal deposits and the biological production of fuels. Zimbabwe imports more than 30 percent of its electricity from neighboring countries.
Power and water outages have become routine in Zimbabwe, which is caught in its worst economic crisis since independence from Britain in 1980.
