The National Electric Power Regulatory Authority (Nepra) on Monday indicated another increase in electricity tariff by Rs7.90 per unit on account of monthly fuel adjustment (MFA) for May 2022. The Central Power Purchasing Agency-Guarantee had submitted an application for an increase of Rs7.96 per unit, Nepra said. The cost of electricity obtained from the RLNG was Rs27.92 per unit and it contributed to 22.89% of the electricity produced in the country. In contrast, the cost of power produced from coal was Rs18.01 per unit, but only 13.77% of total electricity produced in the month of May was generated from coal. The higher rates of energy prices would also hit the economic growth of the country due to higher cost of doing business.
