It said the electricity sent out by the GenCos was up by 2.6 megawatt from the figure released.
It, however, said 2,144.50 megawatts could not be generated due to unavailability of gas.
The report said zero megawatt was also not generated due to unavailability of transmission infrastructure during the period.
Similarly, it said 1,719 megawatts was not generated due to high frequency resulting from unavailability of distribution infrastructure.
According to the report, zero megawatt was recorded as losses due to water management procedures.
On sector reform and activities, it said the dominant constraint for Thursday was unavailability of gas.
