India’s Largest Solar EV Hub Drives Green Mobility in Kolkata

Greaves Electric Mobility

Expansion plans include the development of ten additional charging hubs along the 250-km Kolkata–Asansol highway by 2026. The project also aims to increase the share of renewable energy to 60%. Continuous improvement of AI capabilities will enhance predictive charging and grid management. Furthermore, the model is being positioned for replication in ASEAN and African countries.

Location: Togami, Thakurpukur, Kolkata (repurposed 2-acre site of defunct AYCL plant) Capacity: 6 MW total load Renewable 

Share: 40% (2.4 MW from solar and wind) 

EV Chargers: 300 units (20% fast chargers up to 120 kWh, 80% slow chargers) 

Manufacturing: 80% domestically made in Himachal Pradesh 

Timeline: Commissioning by August 2025 

Primary User: Snap-E’s 300 electric cabs

Challenge and Context : 

Kolkata faces mounting urban pollution with over 4.5 million registered vehicles, creating an urgent need for sustainable transportation solutions. Additionally, India’s commitment to reach net-zero emissions by 2070 requires innovative approaches to energy and mobility. The project also aimed to address the challenge of repurposing underutilized public sector land while building clean energy infrastructure. 

Microgrid Architecture : 

  • Decentralized microgrid combining solar panels, wind turbines, and Battery Energy Storage Systems (BESS) 
  • Ensures 24/7 operational reliability with 40% reduced reliance on the main grid 
  • Future-ready design allowing for increased renewable contribution in subsequent phases Smart 

Charging Ecosystem : 

  • AI and IoT-powered Charging Management System (CMS) for real time load balancing 
  • Predictive maintenance capabilities and dynamic pricing 
  • Optimized charger availability and energy utilization 

Energy Efficiency Strategy : 

  • Solar generation meets daytime demand with excess stored in BESS for nighttime use 
  • Grid power serves as backup during peak loads or shortfalls 
  • Intelligent load management prevents overloading fossil-based infrastructure

The EzUrja-AYCL solar-powered EV charging hub represents a significant advancement in India’s transition to clean mobility. By combining renewable energy, smart grid technology, and domestic manufacturing, the project offers a replicable model that balances sustainability with economic development. This case study demonstrates how public-private partnerships and innovative microgrid solutions can create scalable, environmentally beneficial transportation infrastructure for developing economies.

Mathematical Proof of Effectiveness: 

1. Renewable Energy Generation 

Annual Renewable Energy = Capacity (MW) × Renewable Fraction × Hours per Day × Days per year 

= 6 MW × 0.4 × 24 hours × 365 days = 21,024 MWh/year

2. CO₂ Emissions Avoided 

Using India’s official grid emission factor for FY 2023-24: CO₂ Emissions Avoided = Annual Renewable Energy (MWh) × Grid Emission Factor 

= 21,024 MWh × 0.727 tonnes CO₂/MWh = 15,284.45 tonnes 

Note: The grid emission factor of 0.727 tCO₂/MWh is sourced from the Central Electricity Authority’s CO₂ Baseline Database for the Indian Power Sector for FY 2023-24. 

3. Equivalent Tree Sequestration 

A mature tree sequesters approximately 22 kg (0.022 tonnes) of CO₂ per year. Therefore: Number of Trees Required = Emissions Avoided / Absorption per tree 

= 15,284.45 / 0.022 = 694,748 trees 

The annual CO₂ reduction from this hub equals the environmental benefit of nearly 695,000 mature trees.
