Most of the inundation is in Manipur and Mizoram states, whereas it would moderate floods in lower Assam. To ensure fare share of benefits to those two states, hydropower generation is also taken into account. The states in North-East are having severe power shortage over years (peak shortage upto 25% in Arunachal). Once Arunachal starts producing hydroelectricity from giant Subansiri projects, the North-East India will become energy sufficient. On the other hand, there are no alternative to dams for flood-control of a rainfed river. Incidentally, both flood-control and hydropower generation reservoirs work in similar way they retain water during Monsoon and release more during lean season, i.e. reservoir is filled up during rainy season and used up in dry season.
