Sanaa has cancelled a preliminary agreement with the US' Powered Corporation. The deal would have resulted in the firm building five nuclear power plants with a total capacity of 5,000 MW, at a cost of $15,000 million over 10 years. The deal was annulled after intervention by the National Supreme Anti-Corruption Authority, which said the US firm did not have the necessary experience or capital for the project. Powered Corporation could not be reached for comment.
