Bangladesh rooftop solar becomes up to 70% cheaper than grid power after tariff hike

Bangladesh raised electricity tariffs from June 2026 as imported LNG, coal and oil costs widened the power-sector deficit to around BDT 5/kWh. IEEFA estimates that industrial users can save at least BDT 7.56/kWh by self-generating from rooftop solar, before also avoiding the 5% VAT charged on grid electricity. The analysis says the new tariff structure should accelerate rooftop PV, battery storage and efficiency investments among manufacturers seeking lower costs and stronger energy security.
