- The issue was highlighted at the Bharat Climate Forum (BCF) 2026, where policymakers, developers, financiers, and grid planners discussed operational risks in India’s renewable energy transition.
India’s Renewable Energy Transition
India has emerged as one of the leading countries globally in the shift toward clean energy. Rapid expansion of renewable energy capacity has been driven by several factors.
Key drivers include:
- Large-scale government policy support
- Competitive renewable energy auctions
- Growing private sector investment in solar and wind projects
- Declining costs of renewable energy technologies
India has also set ambitious energy transition targets:
- Achieving 500 GW of non-fossil fuel capacity by 2030
- Meeting 50% of energy requirements from renewable sources
- Achieving net-zero emissions by 2070
As a result, renewable capacity has expanded rapidly across states such as:
- Rajasthan
- Gujarat
- Tamil Nadu
- Karnataka
However, despite this growth, structural and operational challenges have begun to emerge.
Stranded Renewable Power in India
One of the most serious challenges facing India’s renewable energy transition is stranded renewable power.
Stranded power refers to situations where:
- Electricity is successfully generated by renewable plants
- But cannot be transmitted to consumers due to grid limitations.
For example:
- In Rajasthan, more than 4,000 MW of commissioned renewable capacity cannot evacuate power during peak hours.
- Rajasthan has about 23 GW of renewable capacity installed.
- However, available power evacuation capacity is only about 18.9 GW.
This leads to curtailment of renewable energy generation, resulting in:
- Financial losses for developers
- Inefficiencies in the power system
- Underutilisation of clean energy resources
Transmission Infrastructure Bottlenecks
Transmission infrastructure is crucial because renewable energy generation is often concentrated in specific geographic regions, while electricity demand is spread across the country.
To address this challenge, large transmission corridors have been developed.
However, many of these corridors are operating far below their design capacity.
Examples include:
- 765 kV double-circuit transmission corridors
- Designed to evacuate around 6,000 MW of electricity
In practice:
- These corridors are often operated at only 600–1,000 MW
- Utilisation levels remain below 20%
These corridors involve massive public investment, with each costing around ₹4,000–₹5,000 crore.
Low utilisation results in:
- Inefficient use of public infrastructure
- Higher cost burden on electricity consumers
Institutional and Operational Challenges
A major cause of grid congestion is the disconnect between infrastructure planning and operational management.
The process typically works as follows:
- The Central Transmission Utility (CTU) plans transmission corridors based on projected renewable capacity.
- Developers receive General Network Access (GNA) approvals to connect their plants to the grid.
- Renewable energy developers invest heavily based on these approvals.
However:
- Operational decisions by grid operators sometimes restrict the amount of electricity that can flow through the corridors.
This results in a situation where:
- Infrastructure exists on paper
- But cannot be fully utilised in practice
Such mismatches reduce investor confidence and disrupt the renewable energy ecosystem.
Curtailment and Financial Risks
Curtailment refers to the forced reduction in electricity generation due to grid constraints.
In some regions:
- Projects with Temporary General Network Access (T-GNA) face complete shutdowns during peak solar hours.
- Projects with Permanent Network Access continue operating.
This creates:
- Unequal financial risk distribution
- Revenue losses for affected developers
Since renewable energy projects involve large upfront investments, prolonged curtailment can discourage future investment in the sector.
Technical Solutions and Global Best Practices
Many technical challenges associated with renewable integration can be addressed through modern grid management technologies.
Key solutions include:
• Advanced reactive power technologies such as STATCOMs (Static Synchronous Compensators)
• Dynamic grid management systems that enable real-time monitoring and contingency management
• Adaptive line rating technologies, allowing transmission lines to carry more electricity under favourable environmental conditions
Countries with high renewable energy penetration have adopted these technologies to balance grid stability and efficient power transmission.
Institutional Reforms Needed
Experts argue that addressing renewable energy integration challenges requires stronger institutional coordination and regulatory reforms.
Key reform measures include:
• Improved grid utilisation targets, ensuring grid operators maximise asset use while maintaining stability
• Transparent curtailment mechanisms so power reductions are distributed fairly among generators
• Dynamic reallocation of unused transmission capacity through real-time systems
• Better coordination between planning agencies and grid operators to ensure infrastructure performs as intended
Conclusion
India’s renewable energy transition has achieved remarkable growth in generation capacity. However, challenges such as grid congestion, stranded renewable power, transmission underutilisation, and institutional inertia threaten to slow progress. Addressing these issues will require not only building more infrastructure but also improving grid management, institutional accountability, and operational efficiency. A balanced approach that ensures both grid stability and effective utilisation of renewable energy resources will be essential for achieving India’s long-term clean energy goals.
