The Supreme Court on Wednesday directed all state electricity regulatory commissions to frame regulations under thelaw prescribing terms and conditions for determination of power tariff within a period of three months. The important direction from the top court came in a verdict by which it dismissed the appeal of TATA Power Company Limited Transmission (TPCT) against a judgement of the Appellate Tribunal for Electricity
(APTEL) which had upheld the grant of electricity transmission license to Adani Electricity Mumbai Infra Limited (AEMIL). 
“We direct all State Regulatory Commissions to frame Regulations under Section 181 of the (Electricity) Act on the terms and conditions for determination of tariff within three months from the date of this judgment,“ the court said. While framing these guidelines on determination of tariff, the Appropriate Commission shall be guided by the principles prescribed in Section 61, which also includes the NEP (National Electricity Policy) and NTP (National Tariff Policy 2006), it said. Granting relief to the Adani group firm, a bench comprising Chief Justice D Y Chandrachud and Justices A S Bopanna and J B Pardiwala said, “The threshold limit not having been notified by MERC, it was open to MERC to allot the HVDC project either under the RTM or TBCBroute. ”
