The Central Electricity Regulatory Commission (CERC) has released a draft proposal for setting generic tariffs for renewable energy projects, aiming to provide a stable and predictable framework for the industry. This move is significant as it aims to streamline the process of determining tariffs for renewable energy projects, which can be complex and time-consuming. The draft proposal covers a wide range of renewable energy technologies, including small hydro, biomass, and waste-to-energy projects, offering a comprehensive approach to the sector's tariff determination.
One of the key aspects of this proposal is the retention of existing capital cost norms. CERC has decided to maintain the current benchmark capital costs for eligible renewable energy technologies, which it believes are still aligned with market conditions. This decision provides a sense of continuity and stability for developers and investors, allowing them to plan and execute projects with a clear understanding of the financial parameters.
The proposed tariffs for specific project types are quite detailed, taking into account various factors such as location, technology, and fuel type. For instance, small hydro projects in certain states are assigned a levellised tariff of ₹6.69 per kWh for capacities below 5 MW, while biomass-based power projects have proposed tariffs ranging from ₹9.5 to ₹11.6 per kWh. These tariffs are designed to incentivize the development of renewable energy projects while ensuring a fair and competitive environment.
CERC's approach to tariff determination also includes considerations for debt-equity ratios, loan interest rates, and useful lives of projects. The normative debt-equity ratio of 70:30, along with a loan interest rate of 10.71%, provides a framework for calculating tariffs that takes into account the financial structure of projects. Additionally, the useful life of projects is proposed to remain consistent, with small hydro projects having a 40-year life and biomass projects having a 25-year life.
The draft proposal also addresses the need for flexibility in tariff calculations, especially for waste-to-energy projects. CERC has proposed a tariff of ₹10.69 per kWh for RDF-based municipal solid waste projects, which reduces to ₹10.14 per kWh after considering accelerated depreciation benefits. This demonstrates a willingness to adapt the tariff structure to the unique characteristics of different project types.
Furthermore, the Commission has emphasized the importance of transparency and fairness in the tariff determination process. It has clarified that any subsidies, grants, or incentives received from the Central or State Government that were not considered during the tariff determination will be adjusted in future tariff payments. This ensures that the tariffs are fair and reflective of the actual costs and benefits associated with renewable energy projects.
In conclusion, CERC's draft proposal for generic renewable energy tariffs is a significant step towards creating a stable and predictable environment for the renewable energy sector. By retaining existing norms, providing detailed tariffs for specific project types, and ensuring transparency, the Commission is fostering a positive and supportive framework for the industry. As the draft proposal undergoes public consultation and feedback, it is expected to play a crucial role in shaping the future of renewable energy in India.
