The Brazilian electricity sector faces a high risk of blackouts in 2015 due to incompetence in government management. A survey found 181 blackouts between 2011-2014, including one in 2013 that affected over 10,000 megawatts across 9 states. The risk of rationing increased to 18.5% in 2014 due to delays in new power plants and transmission lines, increased consumption, and drought reducing hydroelectric output. Mismanagement of price controls, concessions, and reliance on hydropower without sufficient alternatives have damaged the electricity sector and economy.
