The aggregate level of the power generation reservoirs was 81.1% of the useful volume, 2.6% above the level reported in the previous month, which was 78.5%. It should be noted that for the same month in 2015, the level of reservoirs was at 67.7%.

When performing the analysis by hydrological regions, in the East the reservoirs are in 98.8%, in Antioquia in 88.0%, in the Caribbean in 84.6%, in the Valley in 81.4% and in the Center in 61.9%. (See Table 1- Hydrology by regions and Table 2 - State of the reservoirs).

The water contributions closed the month of July with an average of 104.8% with respect to the historical monthly average, standing out mainly the contributions of the Oriente region with 122.3% and of the Caribbean region with 119.7%.

On average, the generation for the month of July was 190.8 GWh / day, of which 87.05% originated with renewable sources (85.77% hydraulic, 1.17% biomass, 0.10% wind and 0.01% solar) and the remaining 12.95% with non-renewable fossil fuels.

For Jaime Alejandro Zapata Uribe, manager of the National Dispatch Center: "After having three months of contributions above the historical average, in July the data was close to the historical average and a stabilization of the aggregate reservoir of the SIN was generated, which represented a growth of 2.6% with respect to the month of June 2018. An increase in the share of renewable sources stands out with 1.8% while the non-renewable decreased by 6.3% compared to the previous month ".
