In 2014 SN Power signed a Memorandum of Understanding (MoU) with the Government of Myanmar. SN Power completed a pre-feasibility study and is now working on a feasibility study.
The area of the Middle Yeywa Hydropower Project is located in Shan State, approximately 80 km east of Mandalay and 55 km east of Pyin Oo Lwin town, on the Myitnge River, a tributary of the Ayeyarwady (Irrawaddy) River.
The Project is located between the Lower Yeywa Hydropower Project already in operation and the Upper Yeywa Hydropower Project currently under construction, forming a potential cascade.
The project will take advantage of the head available between the existing Yeywa reservoir and the Upper Yeywa HPP, while keeping the constraint to have a 5 m difference between the tailwater of Middle Yeywa and the Full supply level of Yeywa as well as between the Full Supply level of Middle Yeywa and the Tailwater level of Upper Yeywa, during normal operations.
The Middle Yeywa HPP will have an installed capacity of 735 MW. The tailwater level is designed at 190 masl and the Full supply level at 317 masl.
