Nagpur Metro Solar Expansion Delayed Due to MSEDCL Approval Hold-Up
Nagpur Metro, one of India’s greenest metro systems, is facing a roadblock in its ambitious solar energy expansion project due to delays in obtaining approval from the Maharashtra State Electricity Distribution Company Ltd (MSEDCL). Despite significant investments in solar infrastructure and the ongoing expansion efforts, the metro network cannot proceed with its plan to power 50% of its energy needs through solar until it receives the necessary clearances from the state electricity body.
Currently, around 20% of Nagpur Metro’s energy consumption is sourced from solar power. However, the metro aims to increase this to 50%, which would make it one of the most sustainable metro systems in the country. In pursuit of this goal, Maha Metro has been actively expanding its solar capacity, with recent installations such as a 1.5 MW solar setup at its Hingna and MIHAN depots. Yet, these newly installed solar plants remain uncommissioned as MSEDCL has yet to approve them. With daily energy consumption of approximately 90,000 units, Nagpur Metro relies on solar power for about 16,500 units. If the metro’s solar capacity expands to 10 MW, it could cover 50% of its energy requirements, resulting in significant savings of up to ₹45 lakh per month. This would also reduce the current monthly electricity expenditure of ₹2.38 crore, a substantial amount that would benefit the financial sustainability of the metro system.
Nagpur Metro operates under the Renewable Energy Service Company (RESCO) model, sourcing solar energy at a favourable rate of ₹3.40 per unit. This is a major cost saving compared to the ₹9.68 per unit tariff charged by MSEDCL. In the fiscal year 2023-24, Nagpur Metro has already generated over 4.715 million units of solar electricity, exporting more than 770,000 units to the MSEDCL grid under a net-metering arrangement.
Despite sending multiple requests to MSEDCL over the course of several months—on April 23, May 14, and September 2, 2023—seeking approval for a 5 MW net-metering arrangement as per the Maharashtra Electricity Regulatory Commission (MERC) guidelines, the approval process remains unresolved. This delay is holding up the completion of the solar expansion, which is vital for Nagpur Metro’s long-term sustainability and cost-saving objectives. A senior official from Maha Metro explained, “We have sent multiple letters to MSEDCL requesting approval for the newly installed solar systems. Once we receive the necessary approvals, we can complete the remaining solar installations within six months and achieve our 10 MW target.” This would mark a significant milestone in making Nagpur Metro a fully sustainable public transport system.
While MSEDCL officials have assured that the approval process is underway, the delay has raised concerns about how long it will take to move forward with the crucial project. The timely approval of the solar installations is key to ensuring that Nagpur Metro meets its sustainability goals and contributes to reducing the overall carbon footprint of the city’s public transport system. Once the approval is granted, Nagpur Metro plans to complete its solar expansion within six months, helping to meet the goal of 50% solar energy consumption and making it a model for sustainable transport systems across India. With this delay now coming to a head, there is hope that the project will soon be able to move forward, significantly enhancing the sustainability of Nagpur’s public transport system for years to come.
