Arunachal Pradesh identified as powerhouse of the country. Even as anti-mega dam groups and organisations in Assam have intensified their agitation, demanding a halt to the ongoing 2,000-MW Lower Subonsiri hydroelectric project of NHPC Limited at Gerukamukh on the Assam-Arunachal Pradesh border, the Union government is pushing for 157 hydro power schemes with an installed capacity of 57,672 MW in the North-East, including Sikkim, for meeting the shortfall in the country's power generation.
