Bhutan: MHPA Unit III resumes power generation after more than 10 months of repair

THIMPHU, 21 August 2021, (TON): After more than 10 months of repair, Mangdechu hydropower plant’s turbine number three resumed power generation.

The 720MW plant shut down its turbine number three on September 20 last year. The management had targeted to complete the repairs by August 20.

According to sources in MHPA “the turbine was connected to the grid after completing all necessary tests. The four turbines together generated 765MW.

A flashover burnt and carbonised the stator (a stationary part of a rotary system) windings and other rotor components inside the generator causing an electric short-circuit.

It was learnt that in monsoon all the four units generate around 197MW each, which is 10 percent additional power above their capacity.
