GERC Approves Record Low ₹2.60/kWh Tariff for 500 MW Solar in Gujarat
The Gujarat Electricity Regulatory Commission (GERC) has set a groundbreaking benchmark in solar power affordability with a winning tariff of ₹2.60/kWh (~$0.0297) for 500 MW of projects. Gujarat Urja Vikas Nigam (GUVNL) will procure this power through an innovative 50-50 split between base capacity and greenshoe options.
Decoding Gujarat’s Record-Breaking Solar Tariff
This ₹2.60/kWh rate – one of India’s lowest for utility-scale solar – stems from cost reduction strategies including:
- Local module manufacturing under PLI scheme
- Optimized land acquisition processes
- Gujarat’s high solar irradiance (5.5 kWh/m²/day)
Greenshoe Option: Strategic Flexibility with Grid Considerations
The 250 MW greenshoe provision allows capacity expansion but faces grid integration challenges. Solutions include:
- Advanced solar inverters for better grid synchronization
- Pumped hydro storage in Kutch region
- Phased commissioning to match infrastructure readiness
Rooftop vs Utility-Scale Solar: Complementary Roles
While this tariff makes utility-scale projects attractive for industrial consumers, residential rooftop solar remains viable for:
- Net metering benefits
- Energy independence during outages
- Space-constrained urban installations
Broader Implications for India’s Energy Transition
This development:
- Underscores solar’s growing competitiveness against coal (₹3.20/kWh)
- Highlights Gujarat’s leadership in renewable adoption
- Sets precedents for upcoming state auctions
