In 2023, the states of Assam and Meghalaya refused to purchase additional electricity generated by the Subansiri Lower Hydroelectric Project (SLHP) citing high tariffs set by the Central Electricity Regulatory Commission (CERC). The SLHP, commissioned by North Eastern Electric Power Corporation Limited (NEEPCO), has an installed capacity of 2,000 MW and a project cost exceeding ₹9,000 crore (CEA 2023). Assam and Meghalaya’s rejection of power priced at approximately ₹4.50 per unit threatens underutilization of this significant infrastructure and exposes gaps in inter-state tariff harmonization under India’s federal electricity governance framework.

This dispute exemplifies the tension between central tariff regulation and state-level acceptance, highlighting the need for clearer mechanisms under the Electricity Act, 2003 and cooperative federalism in power distribution.

Legal and Constitutional Framework Governing Inter-State Power Tariffs

Article 262 of the Constitution empowers Parliament to legislate on inter-state water disputes and related issues, but does not explicitly cover electricity tariff disputes. The Electricity Act, 2003 (No. 36 of 2003) governs generation, transmission, and distribution of electricity, with Sections 61-64 mandating transparent tariff determination by the CERC for central sector projects.

The Central Electricity Authority (CEA), under the Electricity (Supply) Act, 1948, functions as a technical advisor and project monitor. The CERC’s tariff orders are binding but require acceptance by state utilities for power purchase agreements (PPAs). State Electricity Regulatory Commissions (SERCs) have jurisdiction over intra-state tariffs and PPAs, creating potential conflicts.

The Supreme Court’s 2019 ruling in Energy Watchdog vs. CERC emphasized tariff transparency but did not resolve state refusal scenarios, leaving a regulatory lacuna in binding inter-state tariff harmonization.

Economic Dimensions of the Subansiri Power Tariff Dispute

The SLHP’s 2,000 MW capacity represents over 60% of the Northeast’s hydroelectric power capacity (CEA 2023). With an estimated cost of ₹9,000 crore, the tariff of ₹4.50/unit proposed by CERC aims to ensure project viability and recover capital costs.

• Assam and Meghalaya’s refusal to purchase power at this tariff risks annual revenue losses exceeding ₹500 crore for NEEPCO, based on capacity utilization and tariff data.
• The Northeast region faced an 8.5% power deficit in 2023, with demand growing at a 7% CAGR over the last five years (CEA 2023).
• Underutilization of SLHP capacity exacerbates regional power shortages and delays economic development linked to reliable electricity supply.

The economic cost extends beyond revenue loss to include inefficiencies in resource allocation and missed opportunities for regional industrial growth.

Role of Key Institutions in the Dispute

The institutional interplay defines the dispute’s complexity:

• CEA: Technical advisor responsible for project monitoring and capacity assessment.
• CERC: Regulator tasked with tariff determination for central sector projects, including SLHP.
• NEEPCO: Project developer and operator, dependent on tariff acceptance for financial sustainability.
• SERCs of Assam and Meghalaya: Oversee state-level tariff approvals and PPAs, exercising discretion to accept or reject power purchase at proposed tariffs.
• Ministry of Power: Coordinates policy and facilitates inter-state cooperation but lacks enforcement power over tariff disputes.

Comparative Analysis: India vs China on Hydroelectric Project Tariff and Integration

China’s centralized approach to hydroelectric projects, exemplified by the Three Gorges Dam, contrasts sharply with India’s federal model. The International Energy Agency (IEA) 2022 report notes:

Structural Gaps in India’s Federal Electricity Governance

The refusal by Assam and Meghalaya exposes a critical gap in the Electricity Act, 2003: absence of a binding inter-state tariff harmonization mechanism. While CERC’s tariff orders are regulatory, state utilities retain discretion over PPAs, enabling tariff disputes that stall power distribution.

This reflects a broader challenge in cooperative federalism where overlapping jurisdictions of CERC and SERCs create regulatory uncertainty. The lack of a dispute resolution mechanism specifically addressing tariff disagreements between states and central projects undermines efficient resource utilization.

Significance and Way Forward

• Implement a binding inter-state tariff harmonization framework under the Electricity Act to prevent refusal of centrally generated power.
• Strengthen the role of the Ministry of Power as a mediator with authority to enforce compliance in tariff disputes.
• Enhance transparency and stakeholder consultations during tariff setting to balance consumer affordability and project viability.
• Promote integrated regional power markets in the Northeast to optimize hydroelectric resource utilization and reduce power deficits.
• Draw lessons from China’s centralized tariff and grid integration policies to improve capacity utilization and regional development.
