Legal Commentary & Landmark Judgments: Section 2
Section 2 of the Electricity Act, 2003 enacts the statutory dictionary for the entire Act, defining foundational concepts including 'consumer', 'distribution licensee', 'open access', 'captive generating plant', 'dedicated transmission lines', 'generating company', 'trading', 'wheeling', and 'grid' to delineate operational jurisdictions and statutory rights.
In tariff petitions, open access applications, and regulatory penalty proceedings, scrutinize whether an entity strictly falls within 'consumer' under Section 2(15) or an 'open access user' under Section 2(47), as this demarcation governs liability for cross-subsidy surcharges, additional surcharges, and the jurisdictional forum for dispute redressal.
