The solar power plant installed by Power Development Board (PDB) at Baghachola village under Barkal upazila in Rangamati at a cost of Tk 8 lakhs is virtually of no use because of lack of proper maintenance. It was set up there about one year ago under Chittagong Hill Tracts Solar Photovoltaic Electrification Project (CHTSPVEP) to supply power and safe water among households. The technology does not benefit the villagers allegedly due to lack of maintenance by PDB officials, locals told this correspondent during a visit.
