HYDRO POWER POTENTIAL AND ITS DEVELOPMENT

IN MANIPUR

Manipur has hydro power potential of about 2000 MW which is sufficient not only to meet the local requirement for domestic and industrial uses but leave surplus for marketing outside. Thus, the State Government has chosen this sector as a thrust area for development.

The State Government is making preparation to frame a policy of its own to facilitate private participation and investment in the sector. The State is committed to provide an attractive and investment friendly atmosphere. The Government has given top priority in generation sector to develop hydro power potential as one of the major industries. Substantial numbers of skilled unemployed manpower is also available in the State. Road communication, although hilly, is    readily available for the most of the project sites. Evacuation of the power produced in the State can be made through the existing wide and strong network of the North Eastern Grid as well as through the upcoming transmission networks.

The State Power Department has so far identified number of hydro power project sites in the State and these are at different stages of implementation.
