In a recent development, the Central Electricity Regulatory Commission (CERC) has proposed a draft plan for renewable energy tariffs, sparking interest and debate within the industry. This article delves into the key aspects of CERC's proposal and offers an insightful analysis of its potential impact.
The Draft Proposal
CERC's draft proposal aims to set levellised generic tariffs for renewable energy projects commissioned during the fiscal year 2026-2027. The proposal, released on July 3, 2026, covers a range of renewable energy technologies, including small hydro, biomass power, cogeneration, and waste-based projects. Notably, solar, wind, and hybrid energy projects are excluded, as they will continue to be governed by project-specific tariffs.
Key Takeaways
Capital Cost Norms: CERC has decided to maintain the existing capital cost norms for all eligible renewable energy technologies. This decision is based on the Commission's assessment that current benchmark costs align with market conditions, indicating a stable and predictable approach to tariff determination.
Debt-Equity Ratio and Returns: The normative debt-equity ratio of 70:30 has been retained for tariff calculations. Loan interest rates and post-tax returns on equity remain unchanged, providing a consistent framework for project developers.
Useful Life and Escalation Rates: CERC has proposed to continue the existing useful life of renewable energy projects, ranging from 20 to 40 years, depending on the technology. Operation and maintenance escalation rates have also been retained at 5.25%, ensuring a balanced approach to project maintenance costs.
Tariff Rates: The proposed tariffs vary based on project location, technology, and capacity. For instance, small hydro projects in certain states have been assigned tariffs of ₹6.69/kWh and ₹6.02/kWh for projects below and between 5-25 MW, respectively. Biomass-based projects have tariffs ranging from ₹9.5 to ₹11.6/kWh, with adjustments for accelerated depreciation.
Deeper Analysis
One of the fascinating aspects of CERC's proposal is its focus on maintaining stability and predictability in tariff determination. By retaining existing norms and benchmarks, the Commission aims to provide a consistent framework for project developers, fostering a sense of certainty in an industry that often faces regulatory uncertainties.
However, the exclusion of solar, wind, and hybrid projects from the generic tariff mechanism raises questions. These technologies are often at the forefront of renewable energy innovation, and their exclusion might suggest a more conservative approach by CERC. It will be interesting to see how these projects are governed and whether this decision impacts their growth and development.
Furthermore, the proposed tariffs for different technologies highlight the diversity of the renewable energy landscape. The variation in tariffs reflects the unique characteristics and costs associated with each technology, emphasizing the need for a nuanced understanding of the industry.
Conclusion
CERC's draft proposal for renewable energy tariffs offers a glimpse into the Commission's approach to regulating the industry. While the proposal aims to provide stability, it also raises questions about the treatment of certain technologies and the potential impact on innovation. As the consultation process unfolds, it will be intriguing to see how CERC addresses these complexities and finalizes the generic renewable energy tariff order for FY 2026-2027.
