If you shade a map of Maharashtra by mineral wealth, almost all the colour falls in the east — in Nagpur, Chandrapur, Bhandara, Gondia, Gadchiroli and Yavatmal — with a few patches in the southern Konkan and Kolhapur. The vast Deccan plateau in between is almost blank. The reason lies in rock: the Deccan basalt that covers most of the state is poor in economic minerals, while the older rocks of eastern Vidarbha are rich in them.
Why minerals are concentrated in the east
| Rock | Where | Minerals |
|---|---|---|
| Deccan basalt (volcanic) | Most of the state | Few economic minerals; building stone; bauxite and laterite where weathered |
| Archaean and Dharwar rocks (ancient crystalline) | Eastern Vidarbha, parts of Sindhudurg | Manganese, iron ore, chromite, kyanite |
| Gondwana rocks (sedimentary) | Wardha–Wainganga valleys | Coal |
| Vindhyan and other sedimentary rocks | Chandrapur, Yavatmal | Limestone |
Major minerals
Coal
- Where: the Wardha valley and Kamptee coalfields — Chandrapur, Nagpur (Kamptee, Umrer, Saoner), Yavatmal (Wani).
- Who: Western Coalfields Limited (WCL), a subsidiary of Coal India, has its headquarters in Nagpur.
- Use: thermal power stations and industry.
Manganese
- Where: Nagpur and Bhandara districts.
- Who: MOIL Limited (formerly Manganese Ore India Ltd), headquartered in Nagpur, is India's largest manganese ore producer.
- Use: steel-making.
Iron ore
- Where: Gadchiroli (the Surjagarh hills) and Chandrapur; Sindhudurg (Redi, on the Konkan coast).
- Issues: mining in Gadchiroli involves forests, tribal rights and security concerns in a Left-wing extremism-affected region, alongside the promise of jobs and a steel industry in the district.
Bauxite
- Where: Kolhapur (Udgiri, Radhanagari area), Ratnagiri, Raigad, Satara — formed where basalt has weathered into laterite on high plateaus.
- Use: aluminium.
Limestone
- Where: Chandrapur and Yavatmal.
- Use: cement — Chandrapur is a major cement-producing district.
Other minerals
| Mineral | District(s) |
|---|---|
| Dolomite | Chandrapur, Nagpur |
| Chromite | Bhandara, Sindhudurg |
| Kyanite and sillimanite | Bhandara |
| Silica sand | Sindhudurg, Ratnagiri |
| Fluorite | Chandrapur |
Oil and gas
- Mumbai High is an offshore oil field in the Arabian Sea, discovered by ONGC in 1974. It has been one of India's most important sources of crude oil.
- Refineries in the Mumbai region (at Trombay/Mahul) process crude; petrochemical complexes are located at Nagothane and other places.
- A proposed large refinery project in the Ratnagiri region has faced local opposition over environmental concerns — a useful example of development versus environment debates.
Energy
Thermal power
Coal-based power stations are concentrated near the coalfields:
| Power station | District |
|---|---|
| Chandrapur Super Thermal Power Station | Chandrapur — among the largest in the state |
| Koradi and Khaparkheda | Nagpur |
| Mouda (NTPC) | Nagpur |
| Paras | Akola |
| Parli | Beed |
| Nashik (Eklahare) | Nashik |
| Bhusawal | Jalgaon |
| Solapur (NTPC) | Solapur |
Thermal power contributes the largest share of Maharashtra's electricity, which is why air pollution in Chandrapur and Nagpur is a serious concern.
Hydroelectric power
- Koyna — the state's largest hydroelectric project.
- Tata hydro stations at Khopoli, Bhivpuri and Bhira — pioneering projects from the early twentieth century.
- Smaller stations at various dams.
Nuclear power
- Tarapur Atomic Power Station (Palghar district) — India's first nuclear power station, commissioned in 1969.
- Jaitapur (Ratnagiri) — a proposed large nuclear power project with French collaboration, which has faced protests over safety, livelihoods and the ecology of the Konkan coast.
Renewable energy
- Wind: Satara (Chalkewadi, Vankusawade), Sangli, Dhule, Ahilyanagar and other windy ridges.
- Solar: large solar parks, including in Dhule (Sakri); rooftop solar in cities.
- Agricultural feeders: the Mukhyamantri Saur Krishi Vahini Yojana aims to supply farms with solar power through dedicated feeders, so farmers get daytime electricity.
- Bagasse cogeneration: sugar factories generate electricity from bagasse (crushed cane residue).
The power sector's institutions
In 2005, the Maharashtra State Electricity Board was unbundled into:
- Mahagenco — generation;
- Mahatransco — transmission;
- Mahavitaran (MSEDCL) — distribution;
- with MSEB Holding Company as the holding company.
The Maharashtra Electricity Regulatory Commission (MERC) regulates tariffs. In Mumbai, private companies (such as Tata Power, and the city's utilities including BEST and Adani Electricity) also supply power.
Issues
| Issue | Example |
|---|---|
| Pollution from thermal plants | Air quality in Chandrapur; fly ash disposal |
| Mining and forests | Coal mining near Tadoba; iron ore in Gadchiroli |
| Displacement and tribal rights | Mining and dams in tribal areas |
| Protests over big projects | Jaitapur nuclear project; the Ratnagiri refinery |
| Energy transition | Reducing dependence on coal while meeting growing demand |
| Farm power | Night-time supply to farms; subsidy burden |
Practice
Prelims-style:
- Where is Western Coalfields Limited headquartered?
- Which district is known for manganese mining?
- Where are the Surjagarh iron ore deposits?
- Which was India's first nuclear power station?
- When was Mumbai High discovered, and by whom?
Mains-style:
- "Maharashtra's mineral wealth is concentrated in its least developed region." Discuss the implications for regional development.
- Examine the challenges of an energy transition in Maharashtra.
