Gas power projects in Delhi are becoming a tariff-risk flashpoint after Form-15 filings showed steep landed gas-cost increases at three key stations. Indraprastha GTPS saw landed cost rise from Rs. 47.775/SCM in March 2026 to Rs. 74.583/SCM in May 2026. Gas power projects at Pragati PS-I recorded an even sharper movement, from Rs. 42.910/SCM in February to Rs. 69.860/SCM in May. Pragati PS-III rose from Rs. 28.734/SCM to Rs. 33.614/SCM. EnergylineIndia.com highlights this update for readers tracking DISCOMs Latest News and Power generation capacity. The financial impact is large: the three stations together spent about Rs. 354 crore on gas in May 2026 alone. GTPS consumed 13,533.189 thousand SCM of imported gas, while PPS-I consumed 14,689.449 thousand SCM of imported gas. Both received zero domestic gas. Gas power projects at PPS-III still had domestic gas supply of 41,778.251 thousand SCM but also used 2,978.543 thousand SCM of imported gas. Gas power projects therefore face not only price risk but also supply-source risk.
