India’s Cheapest Power is Here, the Grid Must Catch Up
(Source – The Hindu, Editorial Page no. – 8)
Topic: GS-3: Energy Security | Infrastructure | Renewable Energy | Climate Change
Context
- India has become one of the world’s lowest-cost renewable energy producers.
- Solar and wind power are now cheaper than many conventional sources.
- However, transmission infrastructure is emerging as the biggest bottleneck.
- More than 50 GW of renewable capacity remains stranded due to inadequate grid connectivity.
Key Concern
- Renewable projects can be built in 12–18 months.
- Transmission lines often take 3–5 years.
- Delays arise due to:
- Land acquisition
- Multiple approvals
- Right-of-way issues
- Corridor constraints
Why It Matters?
- India currently has:
- 250 GW renewable capacity installed
- 100 GW under construction
- India may require nearly 2,000 GW by 2050 to meet future demand and electrification goals.
India’s Renewable Opportunity
Cheapest Sources of Power
- Solar and wind are now India’s cheapest electricity sources.
- Falling battery prices are improving storage viability.
- Reliable clean power can be delivered at competitive rates.
Grid as the New Constraint
- Generation capacity is expanding rapidly.
- Transmission infrastructure is not keeping pace.
- Without grid expansion, renewable investments remain underutilised.
Four Major Opportunities
Storage at Renewable Sites
- Solar generation is concentrated during daytime.
- Batteries allow power delivery during evening peaks.
- Improves utilisation of existing transmission lines.
- Can unlock nearly 400 GW additional clean energy.
Using Existing Coal Corridors
- Many coal plants operate below capacity.
- Existing transmission infrastructure remains underutilised.
- Renewable projects near coal stations can use spare grid capacity.
- Potential to support around 100 GW additional clean energy.
Leveraging Existing Substations
- Existing substations can accommodate more renewable projects.
- Battery integration can improve load management.
- Helps connect projects quickly without major new infrastructure.
Advanced Conductors
- Modern high-capacity conductors can nearly double transmission capacity.
- No additional land acquisition required.
- Enhances efficiency of existing corridors.
UPSC Value Addition
Challenges in Renewable Transition
- Transmission bottlenecks

- National Electricity Plan
- National Green Hydrogen Mission
- Battery Energy Storage Systems (BESS)
Why Grid Modernisation Matters
Economic Benefits
- Lower electricity costs
- Reduced transmission losses
- Faster renewable integration
- Improved industrial competitiveness
Energy Security Benefits
- Reduced fossil-fuel dependence
- Greater resilience against global energy shocks
- Supports climate commitments
Environmental Benefits
- Faster decarbonisation
- Reduced emissions
- Improved air quality
Challenges
- High upfront transmission investment.
- Regulatory and approval delays.
- Coordination gaps between Centre and States.
- Slow adoption of advanced grid technologies.
- Financing requirements for large-scale storage.
Way Forward
- Upgrade existing transmission corridors before building entirely new ones.
- Deploy large-scale battery storage systems.
- Expand Green Energy Corridors.
- Encourage advanced conductor technologies.
- Integrate renewable energy zones with transmission planning.
- Strengthen Centre–State coordination for faster clearances.
- Develop smart-grid and digital monitoring systems.
Conclusion
- India’s renewable-energy revolution is no longer constrained by the cost of generating clean power but by the ability to move that power efficiently across the country. The next phase of the energy transition will depend on building a smarter, faster and more resilient electricity grid.
