Speakers at a seminar yesterday said if the electricity tariff is raised, it will have a negative impact on the economic growth reducing the Gross Domestic Product (GDP) rate by 1 percent. “If the power tariff is hiked, there’s immense possibility that the GDP growth will decline by 1 percent,” said Mohiuddin Ahmed, president of Bangladesh Mobile Phone Consumers Association (BMPCA). He was presenting a survey report at the programme titled ‘Power Tariff Hike Proposal: Ground Reality’ organised by the BMPCA at the Bangladesh Shishu Kalyan Parishad auditorium in the city.
