BRASILIA, March 3 (Reuters) - Brazil plans to hold its 13th round auction of oil and natural gas exploration and production rights in the second half of 2015, energy minister Energy Minister Eduardo Braga said on Tuesday.
Braga also said that while the country's hydroelectric-generation scenario has improved with recent rains, the situation, where some expect a drought to prompt power rationing, still requires caution. (Reporting by Leonardo Goy; Writing by Jeb Blount in Rio de Janeiro; Editing by Chizu Nomiyama)
