Case Note & Summary
The dispute arose from the interpretation of tariff provisions in the provisional supply and distribution licence issued under the Orissa Electricity Reform Act, 1995. The State of Orissa enacted the Act to restructure electricity supply, establishing the Orissa Electricity Regulatory Commission to issue licences and determine conditions. The appellant, Grid Corporation of Orissa Ltd. (GRIDCO), received provisional licences to operate electricity transmission and supply. The licences allowed GRIDCO to charge tariffs not exceeding 117% of interim tariffs in force as of April 1, 1996. Following the issuance of a revised tariff notification on May 13, 1996, several industries challenged the validity of the tariff increase in writ petitions before the High Court. The High Court upheld the Act's provisions but found that GRIDCO exceeded its authority by raising tariffs beyond 17% for certain consumer categories, quashing the notification and directing a redetermination of tariffs. GRIDCO appealed, arguing that the clause permitted average increases across categories, allowing some to exceed 17% as long as the overall increase remained within limits. The Supreme Court analyzed the interpretations of clause 9.1, emphasizing the need for a purposive construction that would not render parts of the provision redundant. The Court concluded that the High Court's interpretation was incorrect and upheld GRIDCO's tariff notification, allowing for differentiated increases across consumer categories as long as the total revenue increase did not exceed 17%. The judgment set aside the High Court's ruling and dismissed the writ petitions.
Headnote
A) Electricity Law - Tariff Regulation - Interpretation of Tariff Provisions - Orissa Electricity Reform Act, 1995, Section 14(iv) - The court examined the interpretation of clause 9.1 of the provisional licence regarding tariff increases, determining that the appellant could apply different rates to different categories of consumers as long as the overall revenue increase did not exceed 17% over previous rates. The High Court's interpretation was found to render the words 'on average' redundant, leading to the conclusion that the appellant's tariff notification was valid (Paras 22).

Whether the appellant was authorized to increase tariff rates beyond 17% for certain categories of consumers under the provisional supply and distribution licence.
Final Decision
The Supreme Court allowed the appeals, set aside the High Court's judgment, and upheld the validity of the tariff notification dated May 13, 1996, confirming that GRIDCO could apply differentiated increases across consumer categories as long as the overall revenue increase did not exceed 17%.
