Editorial 2 : An Indian Grid for the World
Context: Path forward for the energy sector in India.
Current Energy Challenges in India
- Dependence on Imports
- India spends $130 billion annually on oil and gas imports.
- Economic impacts: It weakens the rupee, fuels inflation, and raises borrowing costs.
- Strategic Imperative: Breaking free from fossil fuel dependence is critical for economic stability and global leadership.
Global Energy Transition
- Shift to Renewables
- Transportation, heating, and industries are transitioning to green electricity like solar & wind.
- Missing Piece: Lack of a global electricity grid (unlike oil’s global trade infrastructure).
- Technological Advancements
- HVDC Transmission: Enables long-distance power transfer.
- Submarine Cables: Capable of operating in deep oceans.
- Falling Battery Costs: Grid-scale storage costs are declining (30% drop in battery prices recently).
India’s Strategic Advantages
- Infrastructure Investments:
- Over $100 billion allocated for grid expansion and modernization by 2030.
- Existing grid links with Nepal, Bhutan, and Bangladesh.
- Visionary Initiatives
- One Sun One World One Grid (OSOWOG): Aims to connect global renewable energy networks.
- Proposed 50 GW energy superhighway from Saudi Arabia to Japan.
Economic & Strategic Benefits
- Cost Efficiency
- CIGRE Study: A global grid would deliver the lowest-cost power to all participating nations.
- India’s solar prices could drop to 1.5 cents/unit with dollar-denominated PPAs.
- Export Potential
- Surplus solar power from Rajasthan could meet peak demand in Saudi Arabia, Greece, and Japan.
- A flip from $130 billion importer to $100 billion exporter of clean electricity by 2047.
Addressing Storage Bottlenecks
- Global Storage Demand
- Net-zero by 2050 requires 4,000 GW of energy storage (50x current capacity).
- Annual investment needed: $177 billion.
- India’s Solutions
- Leverage pumped hydro storage using vast hydropower potential.
- Integrate grid-scale battery storage (BESS) with HVDC transmission to reduce localized storage needs.
Policy Recommendations
- Infrastructure Development
- Award 10 GW HVDC corridors every 3 years to connect Saudi Arabia and Japan.
- Target 50 GW intercontinental capacity by 2035.
- Domestic Manufacturing: Build capabilities in HVDC converters, submarine cables and cable-laying vessels.
- Regional Collaboration
- Unify grids with neighbours (Nepal, Bangladesh) and offer General Network Access (GNA).
- Expand trading links with Europe, Middle East, Africa (EMEA), and Asia Pacific.
Way Forward: Long Term Vision
- Global Energy Hub
- Act as the nodal point for 24/7 renewable energy supply to global markets.
- Develop global electricity trading infrastructure (similar to India’s UPI for payments).
- Economic Impact: Strengthen the rupee, lower inflation, improve credit ratings, and accelerate India’s transition to a developed economy.
Challenges
- High Upfront Costs: Massive investments required in transmission, storage and manufacturing.
- Geopolitical Complexities: Cross-border grid projects require alignment of political and regulatory frameworks.
- Technological Reliability: Ensuring resilience of submarine cables and HVDC systems.
- Competition: Other nations (e.g. China, EU) may also vie for leadership in global energy trade.
Conclusion: India’s path to becoming a clean energy superpower depend on grid modernization, intercontinental connectivity, strategic investments in storage and domestic manufacturing. With decisive action, India can achieve energy dominance by 2047, transforming itself from an importer to a global leader in renewable energy exports.
