CASE STUDY

Powering Marine Logistics with Renewables

As part of our endeavour to be an ESG-forward operator in maritime logistics, we launched Project Uday at our Iron Ore operations in Goa. The project involves installing solar auxiliary power systems on barges to support cleaner onboard energy use. It reduces dependence on diesel-based generation for routine auxiliary loads, improves energy efficiency, lowers emissions and enhances the reliability of essential onboard systems.

Impact statement

The solar system installed on motor vessel Mogri helps reduce around 6.5 tonnes of carbon emissions every year, equivalent to nearly 297 trees planted per barge

Our approach
  • Installed a 2.2 kW onboard renewable energy system using high-efficiency 550 Wp Mono PERC solar modules
  • Deployed a 24V, 200 Ah lithium-ion battery bank to store solar energy for use during night-time and low-sunlight conditions
  • Integrated MPPT-controlled charging to improve battery life, charging efficiency and system stability
  • Enabled clean solar-battery power for critical auxiliary loads, including accommodation lighting and ventilation
  • Reduced reliance on diesel-based generation for routine onboard power needs, while retaining the primary propulsion system
  • Lowered engine running hours, supporting longer service intervals, lower maintenance requirements and improved asset life
Way forward

Project Uday represents a practical step in our net zero pathway. Marine logistics continues to depend heavily on diesel, even for smaller accommodation and auxiliary loads. Shifting these requirements to renewable energy creates meaningful emission reductions and strengthens our Scope 1 decarbonisation efforts. Building on the success of the MV Mogri pilot, we aim to scale an improved and optimised solar powered system across the 21 barge RFS fleet, with extension currently progressing across 10 barges through quick installation and minimal structural modifications. At full scale, the initiative is projected to reduce nearly over 130 tonnes of CO2 equivalent emissions annually, while also improving air quality around riverine communities.
