The work order for retrofitting and automation of Changchey Mini Hydropower Plant in Tsirang Dzongkhag was received from BPC in June 2021. The scope of the work included replacement of the complete existing control panels and instrumentation systems of 2 (two) Nos. of 100 kW crossflow turbine units to make them fit for unmanned operation. Despite some delays in procurement of materials due to the COVID-19 pandemic and disruption in the global supply chain, especially the shortage of semiconductor chips, the project was successfully completed and handed over to BPC on 27 May 2022.
