The Haryana Electricity Regulatory Commission (HERC) is demanding extensive financial, technical, and operational data from state power utilities before finalizing electricity tariffs for the next fiscal year. This move aims to ensure transparency and protect consumer interests. HERC has requested specific details on loans, depreciation, capital works, employee costs, coal quality, and generation performance from utilities like HVPN, HPGCL, UHBVNL, and DHBVNL.
