The Karnataka Electricity Regulatory Commission (KERC) has notified an average tariff hike of 8 per cent for retail supply tariffs for 2017-18. This is significantly lower than the 25 per cent hike sought by the state distribution companies. The average tariff increase for 2017-18 works out to be around 48 paise per unit and ranges from 15 paise to 50 paise per unit for all categories. The tariff is applicable from April 1, 2017. In a separate development, KERC has fixed Rs 4.36 as the tariff for 2017-18 for new MW-scale solar photovoltaic (PV) plants in the state. The tariff is also applicable for all grid-connected megawatt-scale solar PV plants to be commissioned during 2017-18, for which PPAs were signed earlier.
