Shares of state-run miner Coal India saw a notable uptick on Monday, climbing more than 4% during morning trade. The rally followed the company’s announcement that it had achieved its highest-ever monthly coal supplies in October, a milestone that reached a significant 70.3 million tonnes. The stock price touched nearly Rs 407 per share, marking its highest level in two weeks and pushing the company’s total market capitalisation to approximately Rs 2.5 lakh crore.
This record-setting performance comes even as the company navigated several logistical and operational hurdles throughout the month. In an official exchange filing, the Kolkata-headquartered public sector undertaking (PSU) highlighted that the achievement is particularly significant given the necessity to bolster coal stocks at thermal power plants. The miner faced a complex operational environment, citing disruptions caused by unseasonal rainfall, the impact of a cyclone, and the observance of Puja festivities, all of which typically impede production and transport workflows.
The scale of the supply achievement is substantial, with the company crossing the 70 million tonnes (MT) mark for the first time. This figure represents a 19% growth compared to the 59.2 MT supplied during October of the previous year and surpasses the firm's previous monthly record of 69.4 MT, which was set in March 2026. A key contributor to this growth was Mahanadi Coalfields Limited, a subsidiary of the company, which also achieved a milestone by crossing the 20 MT monthly supply mark for the first time.
A critical component of these supply figures is the focus on the domestic power sector. Deliveries to thermal power plants reached an all-time high of 57.1 MT in October, eclipsing the previous monthly peak of 56.5 MT recorded in May 2024. Furthermore, the company managed an average power-sector rake loading of 310 rakes per day throughout the month. This represents the highest-ever monthly average in the company’s history, surpassing the previous record of 302.8 rakes per day achieved in March 2025.
According to an unnamed senior official at Coal India, the achievement is especially notable because records previously restricted to March—the peak performance month of any fiscal year—are now being surpassed in October. The official indicated that with both production and offtake gaining momentum, the company anticipates a period of stock accretion at both power plant sites and pitheads, which is expected to support energy security requirements.
Market analysts observe that while Coal India shares have faced a decline of more than 3% over the past month, they remain up by 1.5% for the year 2026. When viewed against broader indices, the stock has shown resilience, rising 5% over the past year, a period during which the Nifty 50 index saw a significant decline of 9%. Over a longer horizon, the company has delivered substantial returns, gaining 32% over three years and exceeding 140% in five-year returns.
Moving forward, the company’s ability to maintain these logistical efficiencies remains a focal point for investors and power utilities alike. The surge in coal-fired power output, which saw its highest jump in three years as hydro generation slumped, places additional pressure on the firm to sustain high offtake rates. As the company continues to leverage its subsidiary network to ramp up loading capabilities, market watchers will be monitoring whether this momentum persists through the remainder of the fiscal year.
