The project (No. 2 Power Station) is the first and largest run-of-river type of power station ever constructed in Myanmar. In 1954, its 1st stage development was put into implementation as one of the top priorities among the basin's whole power development schemes.

The basin's power development is aimed to regulate the outflow from the Inle Lake into Balu Chaung and to fully harness a high water drop of a series of cascades located in the lower reaches of the Balu Chaung at about 110 km downstream of the lake outlet.


Three power stations (No. 1 to No. 3 power stations) were proposed at the respective sites of the upper, middle, and lower waterfalls (water drop/river stretch: upper fall 79.2 m/8 km, middle fall 442 m/6.4 km, lower fall 122 m/4.8 km). The total power development would be 240 MW, and an aggregate of annual energy output to be produced by these power stations would be 1,642 GWh.

The project (No. 2 Power Station) is sited in the said middle waterfall that constitutes the major portion of the cascades. The 1st stage development was intended to exploit 84 MW with an annual energy output of 235 GWh. The produced energy is sent to Rangoon through a 230 kV/402 km transmission line.

After the completion of the 1st stage development in 1960, the second stage development (84 MW) would subsequently follow with the proposed Mobye regulation dam that is to be constructed on the Balu Chaung at about 70 km downstream of the lake outlet. Thus, the project (No. 2 Power Station - 1st and 2nd stage development) would finally produce 1,193 GWh of energy, annually with stable and increased water discharge by the Mobye dam for power generation.
