The south is going through one of its worst droughts, the National Grid Operator ordered 14 million cubic meters per day be dispatched, the thermoelectric plants will come on in force at zero hours Saturday, Maria das Gracas Foster, head of Petrobras’ gas and energy department, said.
Brazil’s emergency backup thermoelectric power plants, most of which are fired by natural gas, come online when the country’s main hydroelectric generators enter into the dry season to relieve demand on the falling reservoir levels. The dry season is from May 2009-November 2009.
They also come online when regions of Brazil experience from drought, as the south has been experiencing.
