CNG prices increase again across Delhi-NCR, with Indraprastha Gas Ltd (IGL) raising rates for the second time in two days. Multiple outlets report that the latest revision adds Re 1 per kg, effective from May 17, bringing the Delhi CNG price to Rs 80.09 per kg. Several reports also note that this follows a previous increase of ₹2 per kg on May 15, 2026, when Delhi prices moved to Rs 77.09 per kg. NDTV adds that Delhi CNG prices have risen by about Rs 6 over 11 days, from Rs 77.09 per kg before May 15 to Rs 83.09 per kg on May 26, indicating further movement after the two-day window cited in earlier reports. Business Standard and others say IGL attributes the hikes to higher input costs and fuel pricing pressures; Business Standard specifically states that the latest Re 1 increase only marginally offsets those higher costs. In Noida and Ghaziabad, Business Standard reports the new prices as Rs 88.70 per kg, following the latest increase.
