National Plan on Climate Change With the smoothing of variations in the daily electricity demand curve in Brazil, it is possible to optimize the generation of electricity, preventing thermoelectric plants from being dispatched at peak times, and consequently reducing greenhouse gas emissions.. According to the aforementioned study, it is estimated that the solar thermal program, added to the actions currently underway, has the potential to reduce around 1,200 MW at peak hours and reduce energy consumption of 2,200 GWh/year in the year of 2015, if the original goals of installing approximately 15 million square meters by 2015 are maintained (assuming a baseline of 3 million square meters in 2006). This would represent, in 2015, an annual emission reduction of 640,000 tCOe. Efficient Public Procurement Decrees
