Madras High Court Strikes Down Resource Charges on Wind Projects: A Milestone for Renewable Energy

The Madras High Court’s recent decision to nullify the ₹50 lakh per megawatt (MW) ‘resource charge’ imposed on wind power projects has set a significant precedent for India’s renewable energy sector. The ruling quashes arbitrary levies introduced by the Tamil Nadu Green Energy Corporation Ltd (GECL) on wind projects connected to the Central Transmission Unit (CTU), terming them unconstitutional, discriminatory, and lacking statutory authority.

This landmark judgment not only offers immediate relief to developers but also strengthens the broader principles of equality, free trade, and the rule of law, which are vital for the sustainable growth of renewable energy in India.

The Controversy

In August, GECL imposed a resource charge of ₹50 lakh per MW on CTU-connected wind projects. The rationale was to encourage developers to connect to the State Transmission Utility (STU) network, thereby aiding Tamil Nadu’s compliance with Renewable Purchase Obligations (RPOs). However, developers had already been paying ₹30 lakh per MW for infrastructure development and bore additional costs for upgrading substations and arranging alternative power evacuation.

Prominent renewable energy companies, including Tata Power Renewable Energy Ltd, JSW Renew Energy Ltd, and the Wind Independent Power Producers Association, challenged the levy. They argued that it was:

• Legally unsound: Lacking legislative backing.
• Discriminatory: Imposing a financial burden solely on CTU-connected projects while exempting STU-connected ones.
• Anti-competitive: Hindering the financial viability of CTU projects in the national electricity market.

Key Rulings by the Court

The court’s judgment examined several critical issues, including constitutional validity, discrimination, and the levy’s impact on inter-state electricity trade.

1. Lack of Legal Authority:
   The court ruled that GECL lacked the statutory authority to impose the resource charge. Under Article 265 of the Constitution, taxes or levies can only be imposed with legislative backing, which GECL did not have.
2. Overreach of State Jurisdiction:
   Inter-state electricity trade falls under the central government’s jurisdiction. Tamil Nadu’s attempt to tax power sold across state borders was deemed an overreach, reinforcing the central government’s authority in inter-state electricity sales.
3. Unlawful Restrictions on Trade:
   The charges restricted the ability of renewable energy companies to conduct business freely, violating Article 19(1)(g) of the Constitution.
4. Discrimination:
   The court found the charges discriminatory, as they applied only to CTU-connected projects while exempting STU-connected ones. This violated Article 14 of the Constitution, which ensures equality before the law.
5. Unjustified Levy:
   GECL argued that the charge was an administrative fee. However, the court dismissed this claim, noting that wind and hydro projects do not consume natural resources like coal or water, making the levy baseless.

Implications for the Renewable Energy Sector

The judgment is a significant relief for renewable energy developers, particularly those focused on CTU-connected projects, as it eliminates a financial burden that undermined their competitiveness.

1. Strengthened Competitiveness:
   Removing the ₹50 lakh/MW charge ensures that wind power developers can operate more effectively in the national electricity market.
2. Boost to Clean Energy Transition:
   By nullifying arbitrary charges, the ruling promotes the central government’s renewable energy goals and fosters the seamless integration of clean energy into the grid.
3. Reaffirmation of Constitutional Safeguards:
   The judgment underscores the constitutional protections available to renewable energy companies, ensuring fair treatment and a level playing field across states.
4. Encouragement for Investment:
   The decision is likely to encourage more investment in wind power projects, as it addresses a major barrier to their financial feasibility.

Challenges Ahead

While the judgment is a victory for developers, challenges remain:

1. New Compliance Mechanisms:
   The court authorized Tamil Nadu Generation and Distribution Corporation (TANGEDCO) to devise mechanisms for meeting RPOs. This could include requiring developers to allocate a portion of their capacity to the state grid, which may face legal challenges for potentially creating new barriers to inter-state trade.
2. State-Level Resistance:
   Similar levies or restrictions by other states could emerge, creating friction with the central government’s renewable energy policies.
3. Need for Comprehensive Policy Reforms:
   The ruling highlights the need for a cohesive national framework to manage inter-state electricity trade and RPO compliance without undermining renewable energy developers.

Conclusion

The Madras High Court’s decision to strike down the resource charge is a landmark moment for India’s clean energy journey. By upholding the principles of equality, free trade, and legal authority, the judgment strengthens the foundation for a robust renewable energy sector.

As India accelerates its renewable energy transition, the ruling sends a strong message to state entities: policies that discourage clean energy development or undermine inter-state trade will not be tolerated. The path forward lies in fostering cooperation between states and the central government to create a conducive environment for sustainable energy growth.
