The Delhi Power regulator hikes power tariff by up to eight per cent from tomorrow. BSES Yamuna Power Ltd. hike for its consumers is 8 per cent, by North Delhi Power Limited is 7 percent and by BSES Rajdhani is 6 percent.

Meanwhile, NTPC has rejected Delhi Government's plea not to stop power supply to BSES Yamuna Power Ltd for defaulting on payments. NTPC has warned snapping of power supply, if payment not made today.

BSES Yamuna, which supplies electricity to nearly 14 lakh households, has written to Delhi's Power Secretary that unless state power firms such as NTPC and NHPC provide electricity on credit, power cuts would begin from tomorrow. BSES Yamuna, BSES Rajdhani and Tata Power Delhi Distribution Ltd distribute electricity to 46 lakh consumers in the state.
