ANNOUNCEMENTS
India’s renewable energy (RE) sector, pivotal to achieving 500 GW of non-fossil fuel capacity by 2030 and net-zero emissions by 2070, relies significantly on the wind-solar hybrid (WSH) model to optimize grid reliability and resource efficiency through complementary generation profiles. As of April 2025, India’s renewable capacity stands at 220.1 GW, with solar contributing 107.945 GW, wind 51.059 GW, and WSH 7,705 MW, ranking the country as the third-largest RE producer globally (MNRE, 2025). However, policy volatility, inconsistent implementation, and structural challenges undermine investor confidence and business viability, particularly in the WSH sector. This abstract evaluates the impact of fluctuating policies such as the Accelerated Depreciation (AD) scheme, Generation-Based Incentives (GBI), Feed-in Tariffs (FiTs), and the shift to competitive bidding in 2016-17 on the RE sector’s development, with a focus on WSH. It incorporates insights from interviews with Independent Power Producers (IPPs) to study their decision-making processes in navigating these challenges, alongside a comprehensive analysis of diverse RE policies influencing sectoral growth.
Interviews with IPPs reveal that policy volatility significantly shapes their decision-making in WSH auctions. Firms adopt cautious, data-driven bidding strategies, factoring in regulatory unpredictability, land acquisition delays, grid connectivity constraints, and market risks like fluctuating tariff ceilings and rising solar module prices (up 30-40% in 2021–22) (JMK Research, 2023). IPPs prioritize site-specific resource assessments, financial modeling, and scenario planning, while seeking robust contract clauses, such as change-in-law provisions and expedited Power Purchase Agreement (PPA) execution, to mitigate risks. The weak financial health of state distribution companies (DISCOMs), marked by payment delays and contract renegotiations, further discourages aggressive bidding, leading to under-subscription (e.g., 2.2 GW awarded out of 4 GW tendered in 2022) and project deferrals (Mercom India, 2022). States like Gujarat and Tamil Nadu, with supportive policies and better infrastructure, attract more IPP investment, while regulatory inconsistencies elsewhere deter participation.
The 2018 National Wind-Solar Hybrid Policy has promoted WSH systems by enabling co-location, simplifying approvals, and allowing flexible solar-wind ratios, with 2023 MNRE guidelines further enhancing project flexibility (MNRE, 2023). However, the sector’s growth is constrained by a lack of empirical research on WSH systems, particularly regarding optimal wind-solar mixes, cost-benefit trade-offs, and grid stability under India’s dynamic load conditions. Few large-scale pilot studies or longitudinal performance analyses exist across diverse Indian geographies, limiting evidence-based scaling. This research gap, combined with policy volatility, hinders the sector’s sustainable growth. Other RE policies, such as domestic content requirements (e.g., the Approved List of Models and Manufacturers) and import duties on solar modules, have increased project costs, further impacting IPPs’ risk appetite and bidding strategies (JMK Research, 2023).
To address these challenges, this analysis recommends long-term policy roadmaps to ensure stability, streamlined land acquisition and grid connectivity, and harmonized state-level regulations to reduce disparities. Tariff floors or viability gap funding can mitigate auction-related financial risks, while public-private partnerships for WSH-specific research can bridge gaps in operational and commercial data. Recent policy amendments, such as location-specific interconnection mandates and mandating PPA execution within 30 days, are positive steps (MNRE, 2023). However, broader reforms are needed to strengthen DISCOMs’ financial health, enhance grid infrastructure, and align diverse RE policies such as RPOs, banking, wheeling, and fiscal incentives with national goals. Insights from IPP interviews underscore the need for predictable policy frameworks to support strategic decision-making, emphasizing standardized PPAs, enforceable contract terms, and transparent tariff mechanisms. By addressing policy volatility, research gaps, and operational challenges, India can bolster investor confidence, accelerate WSH deployment, and advance its RE sector toward achieving a sustainable, low-carbon future aligned with global climate commitments.
