Why in News ?

India’s updated Nationally Determined Contribution (NDC) targets 60% non-fossil power capacity by 2035. However, rising geopolitical tensions, grid inefficiencies, and renewable curtailment have exposed structural weaknesses in the power sector. The debate has shifted from capacity addition to ensuring reliable, affordable, and resilient energy systems that contribute to a pollution free environment while navigating complex environmental clearance processes.

Changing Energy Security Paradigm in India:

  • New Definition: Energy security is no longer about mere access but about resilience, reliability, and domestic strength amid global disruptions.
  • Geopolitical Risks: Conflicts like tensions involving Iran highlight the fragility of global energy supply chains.
  • Import Dependence: India’s reliance on imported fuels increases vulnerability to price shocks and supply disruptions.
  • Renewable Push: Expansion of renewable energy (RE) aims to reduce external dependence but introduces variability challenges while requiring streamlined environmental clearances.
  • Strategic Shift: Focus must move from quantity of capacity to quality of power delivery and system resilience, guided by the precautionary principle.

Renewable Energy – Key Concepts & Provisions

Core Concepts

  • Nationally Determined Contributions (NDCs): Climate targets under the Paris Agreement guiding emission reductions and energy transition.
  • Renewable Energy (RE): Clean energy from solar, wind, hydro, reducing fossil fuel dependence.
  • Energy Security: Ensuring reliable, affordable, and resilient energy supply amid global uncertainties.
  • Grid Flexibility: Power system’s ability to handle variability from intermittent sources.
  • Ancillary Services: Grid support functions like frequency control, voltage stability.
  • Curtailment: Forced reduction of renewable generation due to grid or demand constraints.
  • Dispatchability: Capability to deliver electricity on demand, critical for reliability.
  • Environmental Impact Assessment: Systematic evaluation of environmental consequences of proposed renewable energy projects.

Key Facts

  • India aims for 500 GW non-fossil fuel capacity by 2030.
  • Renewables form ~50% of installed capacity, but only ~25% generation share.
  • Solar tariffs (₹2–3/unit) are among the world’s lowest.
  • Rajasthan witnessed up to 50% RE curtailment (2025).
  • DISCOM losses ~₹1 lakh crore, indicating structural inefficiencies.
  • Power demand rising rapidly in states like Chhattisgarh (~7% annually).

Policies, Schemes & Legal Framework

  • Electricity Act, 2003: Backbone law governing generation, transmission, distribution.
  • National Electricity Policy (2005): Framework for power sector reforms and access.
  • UDAY Scheme (2015): Financial restructuring of DISCOMs.
  • Revamped Distribution Sector Scheme (RDSS): Focus on digitalisation, smart metering, efficiency.
  • National Solar Mission: Promotes large-scale solar deployment under climate goals.
  • EIA Notification: Governs environmental clearances for renewable energy projects and transmission infrastructure.
  • Forest Conservation Act: Regulates land use for renewable installations and grid expansion projects.
  • Environmental Jurisprudence: Evolving legal framework incorporating polluter pays principle and environmental democracy in energy sector decisions.

Capacity vs Generation: The Core Paradox

  • Installed Capacity Growth: India has over 250 GW of non-fossil capacity, nearly half of total installed capacity.
  • Low Generation Share: Despite this, renewables contribute only about 25% of actual electricity generation.
  • Intermittency Issue: Solar and wind are variable sources, unlike coal which provides steady output.
  • Underutilisation: Large-scale curtailment (e.g., Rajasthan 50% solar curtailment) shows inefficiency.
  • Key Question: Can renewable capacity ensure round-the-clock (RTC) power?

Grid Infrastructure: Structural Constraints

  • Coal-Based Legacy Grid: India’s grid was designed for centralised, predictable coal generation.
  • Mismatch with RE: Renewables require decentralised, flexible, and dynamic grid systems.
  • Intra-State Weakness: While inter-state transmission improved, intra-state networks remain inadequate.
  • Surplus vs Shortage: Clean energy is wasted in one region while another depends on costlier thermal power.
  • Future Need: Investment in substations, last-mile connectivity, and grid modernisation is critical, requiring comprehensive environmental impact assessment for new transmission corridors.

Market Design Flaws in Electricity Sector

  • Energy-Centric Model: Current markets treat electricity as a single commodity (units consumed).
  • Three Components Ignored: Electricity actually includes:

○ Energy (generation)

○ Capacity (availability during peak demand)

○ Flexibility (response to fluctuations)

  • No Price Signals: Lack of valuation for flexibility discourages investment in storage and hybrid systems.
  • Global Models: Countries like the UK and US (PJM market) reward availability and ancillary services.
  • Reform Need: Shift to multi-product electricity markets for efficient pricing.

Role of Flexibility and Storage in Renewable Transition

  • Demand-Supply Mismatch: Solar peaks during the day, while demand rises in the evening.
  • Storage Requirement: Batteries and pumped hydro are essential for balancing supply fluctuations.
  • Hybrid Systems: Combining solar, wind, and storage enhances dispatchability.
  • Investment Gap: Lack of incentives prevents large-scale adoption of energy storage solutions.
  • Policy Direction: Create clear revenue streams for flexibility services.

Distribution Sector: The Weakest Link

  • Financial Stress: DISCOM losses stand at around ₹1 lakh crore, reflecting systemic inefficiency.
  • Cross-Subsidisation: Industrial users pay higher tariffs to subsidise agriculture and households.
  • Distorted Pricing: This masks real costs and discourages efficiency improvements.
  • Reform Limitations: Past reforms provided temporary relief but failed to address structural issues.
  • Critical Need: Sustainable reforms in distribution are essential for the energy transition’s success.

Demand Management and Structural Reforms

  • Feeder Segregation: Separating agricultural and non-agricultural feeders improves efficiency and transparency.
  • Solarisation of Agriculture: Dedicated solar systems ensure reliable daytime power for farmers.
  • Subsidy Rationalisation: Transition towards Direct Benefit Transfers (DBT) reduces inefficiencies.
  • Demand Response: Consumers should be incentivised to adjust consumption patterns.
  • State-Level Innovations: States like Maharashtra show promising results in distribution reforms.

Challenges:

  • Intermittency Challenge: Renewable sources like solar and wind are inherently variable, making grid balancing difficult.
  • Grid Limitations: Weak intra-state transmission networks restrict efficient power flow and increase curtailment.
  • Financial Crisis of DISCOMs: Persistent losses reduce their ability to invest in modernisation and reforms.
  • Lack of Market Signals: Absence of pricing for capacity and flexibility services discourages innovation.
  • Curtailment Losses: Renewable energy wastage undermines both economic efficiency and climate goals.
  • Policy Fragmentation: Coordination gaps between central and state policies delay implementation.
  • Storage Constraints: High costs and limited deployment of battery storage systems hinder transition.
  • Cross-Subsidy Burden: Distorted tariff structures discourage industrial competitiveness.
  • Technological Gaps: Limited adoption of smart grids and digital infrastructure.
  • Global Uncertainty: Geopolitical risks continue to impact energy markets and supply chains.
  • Regulatory Delays: Issues related to ex post facto environmental clearances and retrospective environmental clearances for existing projects create implementation bottlenecks.
  • Environmental Compliance: Balancing rapid renewable deployment with environmental impact assessment requirements under coastal regulation zone norms and forest clearances.

Way Forward:

  • Grid Modernisation: Strengthen intra-state transmission systems, substations, and smart grid technologies with proper environmental clearances.
  • Market Reforms: Introduce separate pricing for energy, capacity, and flexibility services.
  • Storage Expansion: Promote battery storage, pumped hydro, and hybrid renewable projects through incentives.
  • DISCOM Reforms: Improve financial health via tariff rationalisation, efficiency measures, and governance reforms.
  • Feeder Segregation: Scale up separation of agricultural feeders and implement solarisation programs.
  • Demand Response Mechanisms: Encourage consumers to shift usage through time-of-day tariffs.
  • Policy Integration: Enhance coordination between central and state governments for uniform reforms, strengthening environmental democracy in decision-making.
  • Digitalisation: Deploy smart meters and AI-based grid management systems.
  • Private Sector Participation: Attract investments in renewables, storage, and grid infrastructure.
  • Resilience Building: Focus on energy independence and diversified energy mix.
  • Regulatory Streamlining: Expedite environmental clearance processes while upholding the precautionary principle and polluter pays principle to avoid ex-post facto approvals.
  • Legal Framework Strengthening: Align renewable energy policies with evolving environmental jurisprudence and constitutional mandates for sustainable development.

Conclusion:

India’s renewable transition has reached a critical juncture where scale must give way to system reliability. True success lies not in installed capacity but in delivering consistent, affordable, and resilient power toward achieving a pollution free environment. A fundamental reset in grid design, market structure, and distribution governance is essential for achieving sustainable energy security while respecting environmental safeguards and regulatory frameworks that ensure balanced development.
