Closed coal mines to solar: Can boost global capacity by 15%; India ranks 4th, sites in five states
BATHINDA: Coal mines that have been abandoned or will be closed by the end of this decade hold enough potential photovoltaic (PV) solar capacity, finds a new report from Global Energy Monitor (GEM), a dataset of utility-scale solar photovoltaic (PV) and solar thermal facilities, released early Wednesday.
The first-of-its-kind analysis draws on data in the Global Coal Mine Tracker, a dataset of coal mines, to identify 312 surface coal mines that have been idled and degraded since 2020. These abandoned mines sprawl over 2,089 square kilometres (km²). With repurposing, these coal-to-solar projects could site 103 gigawatts (GW) of solar power capacity on derelict lands.
The analysis further identifies 3,731 km² of mine land that may be abandoned by operators before the end of 2030, owing to the depletion of reserves and the reported life of the mine.
If those operations close, they could site an additional 185 GW of solar power capacity.
In total, an estimated 446 coal mines and 5,820 km² of abandoned mine lands could be suitable for solar repurposing. With development, those projects could harbor nearly 300 GW of photovoltaic solar potential, equivalent to 15% of the globally installed solar capacity.
India ranked fourth after Australia, Indonesia, USA, where estimated solar potential of 27.11 GW from 63 coalmines with land area 546.76 square km has been found.

These mines are in Jharkhand, MP, Chhattisgarh, Odisha, Telangana.
The new data on coal-to-solar projects shows that China has 90 operational coal mine-to-solar conversions, with a capacity of 14 GW, and 46 more projects, with 9 GW, in planning, while the next four major coal producers — Australia, the US, Indonesia and India— have nearly three quarters of the global potential for coal to solar transitions.
Not only would this conversion help the world towards the global goal of tripling renewables capacity by the end of the decade, but it would also provide an economic incentive for reclamation and cleaning up the mess left after mining, which is not standard routine in much of the world.
The report estimates 259,700 permanent jobs could be created at coal-to-solar transition sites, and another 317,500 temporary and construction jobs, more than the number of workers that the coal industry is expected to shed globally by 2035.
The greatest potential for solar redevelopment on mine lands is found in some of the world's largest coal-producing countries — Australia, Indonesia, the United States, and India.
Cheng Cheng Wu, Project Manager for the Energy Transition Tracker at Global Energy Monitor, said, 'The legacy of coal is written into the land, but that legacy does not have to define the future. The coal mine to solar transition is underway, and this potential is ready to be unlocked in major coal producers like Australia, the U.S., Indonesia and India.
Repurposing mines for solar development offers a rare chance to bring together land restoration, local job creation, and clean energy deployment in a single strategy.
With the right choices, the same ground that powered the industrial era can help power the climate solutions we now urgently need.'
Hailey Deres, Researcher at Global Energy Monitor, said 'Acquiring land for global renewable energy targets has been rife with conflicts among stakeholders and decision-makers, so repurposing degraded lands could provide salient new benefits to former coal communities across the planet.'
Ryan Driskell Tate, Associate Director at Global Energy Monitor, said 'We've seen what happens in coal communities when companies go bankrupt, axe the workers, and leave a mess behind. But mined-out coalfields harbor huge potential for powering a clean energy future. It's already happening. We just need the right mix of incentives to put people to work building the next generation of solar in coal country.'

Questioned by mininster, Gurgaon civic body stands by its use of sweeping machines
Gurgaon: The corporation has found nothing wrong with the operations and maintenance of mechanical road sweeping machines (MRSMs) in the city. These MRSMs have proven to be economical, productive and environmentally suitable options for road sweeping in the city, an MCG probe panel has said. According to the report submitted by the MCG panel — which TOI has accessed — these machines (16 are in use in the city) traverse 480km each day, offering improved accountability, decreasing dependency on manual workers, while adhering to pollution control standards. It was in April that the department of urban local bodies (ULB) extended the contract of the operating firm of the road sweeping machines by one year. The extension coincided with the period when concerns about these machines' effectiveness emerged. Out of 44 machines, used across various state corporations, 16 machines are being operated in the city and five in Manesar. The use of these machines is "more cost-effective" than manual sweeping by sanitation workers, the panel has said. According to the MCG's cost analysis, a single sweeping machine can cover 30km of road each night. The monthly cost for manual sweeping of the same 30km stretch is Rs 15.8 lakh. This figure is based on the need for 90 sanitation workers, with three workers allocated per kilometre as per Central Public Health and Environmental Engineering Organisation (CPHEEO) norms and three supervisors required for the 90 workers, each earning Rs 16,900 and Rs 20,000 respectively. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like 5 Books Warren Buffett Wants You to Read In 2025 Blinkist: Warren Buffett's Reading List Undo In contrast, the monthly operational and maintenance cost of one sweeping machine, as per the report, is Rs 4.7 lakh, with an additional Rs 1.87 lakh as fuel expenses each month, totalling Rs 6.57 lakh for each machine. The MCG concluded that the use of sweeping machines, costing Rs 6.57 lakh per month, is more economical than the Rs 15.8 lakh required for manual sweeping of the same distance. "The use of MRSMs has proven to be a cost-effective, efficient and environmentally compliant solution for road cleaning in Gurgaon. However, there are certain other technology vehicles, such as self-propelled mechanical road sweepers, that can also be considered in comparison to vehicle-mounted mechanical road sweeping machines. In the present scenario, after minor operational changes, these MRSM systems can be made more effective," the report says. Meanwhile, ward 11 councillor Kuldeep Yadav said the absence of a councillor or mayor in the MCG's committee examining sweeping machines' effectiveness and cost analysis raises questions. "Our inclusion would have contributed valuable insights from field observations. Councillors possess comprehensive knowledge and maintain thorough supervision of actual operations of the sweeping machines," Yadav said. The MCG panel was constituted in May. On May 9, Badshapur MLA and Haryana industries and commerce, forest and environment minister Rao Narbir Singh said he would conduct an investigation into the functioning of sweeping machines and super sucker machines run by MCG and MCM. The MCG panel had been constituted to evaluate how well the mechanical sweeping systems function, their operational effectiveness, difficulties faced and cost considerations, alongside a comparative analysis with conventional manual sweeping . The minister had questioned whether the machines' use justified their cost. The sweeping machines were purchased by ULB in 2019. Subsequently, the operations and maintenance of 44 such machines across various state corporations were outsourced to a private company for five years, although the machines remain the property of ULB. TOI reported on April 22 that the sweeping machines managed by a private contractor for MCG, which should operate throughout the night on city roads, were underperforming. "We have assigned duties to 16 clerks to monitor each of these sweeping machines throughout their working hours. It will ensure their efficient working," MCG commissioner Pradeep Dahiya said.

Gateway cargo at Vizhinjam port likely only by Dec 2025
Thiruvananthapuram: Gateway cargo operations at Vizhinjam International Seaport are now likely to begin only by Dec 2025 or January 2026, with temporary road access to NH-66 still under construction. According to Divya S Iyer, managing director of Vizhinjam International Seaport Ltd (VISL), preparations are underway for a phased rollout of export-import (exim) cargo operations to coincide with the port's first full year of commercial activity. "We're planning to initiate exim cargo traffic around Dec this year," Iyer said. "The rollout will be gradual to match infrastructure readiness. Cargo movement will increase steadily rather than launch at full scale. " Since its commercial launch in July 2024, Vizhinjam port has operated primarily as a transshipment hub. The addition of exim cargo handling will mark a significant expansion, boosting both regional and international trade. The temporary 1.7-kilometre road linking the port to NH-66 is nearing completion and is expected to be ready by the time gateway services commence, easing container truck movement and reducing congestion. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like 5 Books Warren Buffett Wants You to Read In 2025 Blinkist: Warren Buffett's Reading List Undo However, sources indicate the state govt is in no rush to begin gateway operations, despite ports minister VN Vasavan's earlier assurance that services would start by July 2025. "Progress on the temporary road is slowed by the monsoon. A retaining wall still needs to be built at a 150-metre stretch between a bridge and NH-66, and service roads on both sides must be widened," a source said. The port users' building, which will house customs officers, has been completed and a scanner has been installed near the gateway to inspect cargo trucks. One major pending decision involves the proposed cloverleaf interchange at the NH-66 junction. Though NHAI has given in-principle approval, final clearance is awaited due to a delay in the state govt's review. Port secretary A Kowsigan is currently on deputation training and a final decision is expected after a joint meeting between the ports department and PWD. Estimated at Rs 360 crore, the cloverleaf design requires 30 acres of land and could be jointly funded by the state govt and Adani Group, with the Centre potentially covering 50% of the cost. Until then, the temporary road will act as a stopgap, supporting the gradual ramp-up of cargo operations.
