Renewable hydropower energy potential and capacity beside the Bangladesh.

Myanmar has almost 200 large dams. Myanmar (Burma) has a large hydroelectric power potential of 39,000 megawatts.

Nepal endows with approximately 6,000 rivers with a total length of 45,000 kilometers (km). Nepal's technical potential production for hydropower has been estimated to be 83 gigawatts (83000 magawatts).
But 42,000 Megawatts is considered as economically viable

Bhutan also blessed with hills & river. Bhutan's potential hydropower output is estimated at 30,000 megawatts (MW), [Source: ADB. 2013. Energy Outlook for Asia and the Pacific]

India's total potential of 145,320 MW hydropower in viable consideration. But The Northeast part (known as seven sisters) of India is blessed with about 62,000 MW hydro power potential capacity.

Pakistan is also having almost 60,000 MW of hydropower potential in viable condition, But It has been developed only 7,320 MW.
