The total capacity of Hirakud Dam’s powerhouse is 347.5 MW.
Purpose Of Hirakud Dam
This dam was constructed to help flood conditions which may damage the crops. This was created with a reservoir and control the flow of the river through a drainage system. The dam regulates the water flow of the Mahanadi river and produces hydroelectricity via several hydroelectric plants. This dam helps control flood situations in the Mahanadi delta area.
The water released by this power plant irrigates the Mahanadi delta, this dam can generate up to 307 MW of electrical power via its two power plants. This project also provides flood protection to the delta area of Cuttack and Puri districts.
