Strategic Significance
The Arun-3 project is a cornerstone in the energy cooperation between Nepal and India. It aligns with a broader bilateral agreement wherein India has committed to purchasing 10,000 MW of electricity from Nepal over the next decade. Additionally, India's SJVN Ltd. has been entrusted with developing other hydropower projects in Nepal, including the 669 MW Lower Arun and the 490 MW Arun-4, the latter being a joint venture with Nepal's state-owned Nepal Electricity Authority .
