Tamil Nadu Unveils Draft Multi-Year Tariff (MYT) Framework Through 2032

May 14, 2026

The Tamil Nadu Electricity Regulatory Commission (TNERC) has issued a landmark draft for the Multi-Year Tariff (MYT) framework, spanning from FY 2025-26 all the way to FY 2031-32. This comprehensive document serves as the financial and operational “rulebook” for the state’s power sector for nearly a decade. By moving away from short-term, unpredictable price hikes, Tamil Nadu is attempting to provide the industrial and renewable energy sectors with the long-term cost visibility they have been craving.

The framework sets the “ceiling” and “floor” for power tariffs, covering everything from generation and transmission to retail supply. For the state’s massive industrial clusters—including the SIPCOT zones—this draft is a critical signal. It outlines how the state plans to recover costs while transitioning to a greener grid, including specific provisions for “Green Power Tariffs” for corporations looking to meet 100% renewable goals. By defining these parameters now, the commission aims to make the state’s DISCOMs (distribution companies) more “bankable” and attractive for large-scale infrastructure loans.

For renewable energy developers, the MYT framework is equally vital as it influences cross-subsidy surcharges and additional surcharges for open-access consumers. As Tamil Nadu continues to be a leader in both wind and solar, this 7-year roadmap is designed to prevent “tariff shocks” that could otherwise derail industrial growth. The draft is now open for public comment, marking a high-stakes period for industry stakeholders to shape the economic landscape of India’s most industrialized state.
