Sonbhadra is a district in the south-eastern corner of the Indian state of Uttar Pradesh. Headquartered at Robertsganj, it is the second-largest district in Uttar Pradesh by area and is notable for being the only district in India that shares its borders with four other states — Madhya Pradesh, Chhattisgarh, Jharkhand and Bihar. The district is known for its substantial mineral wealth, dense forests, and concentration of thermal power plants, earning it the informal title of the "energy capital" of India.

Geography
Sonbhadra lies in the Vindhya and Kaimur hill ranges, with the river Son flowing through it and giving the district its name. The terrain is largely hilly and forested, in contrast to the alluvial plains that dominate most of Uttar Pradesh. The Rihand reservoir (Govind Ballabh Pant Sagar), one of the largest artificial lakes in India, lies within the district and supplies water for power generation and irrigation.
The district is bordered by Mirzapur and Chandauli districts of Uttar Pradesh to the north, Bihar (Kaimur district) and Jharkhand (Garhwa district) to the east, Chhattisgarh (Koriya/Balrampur) to the south, and Madhya Pradesh (Singrauli and Sidhi) to the west.
History
Sonbhadra was constituted as a separate district on 4 March 1989, when it was carved out of the erstwhile Mirzapur district. The area has a long history of human settlement; rock paintings and shelters in places such as Lakhania and Vijaygarh point to prehistoric occupation. In medieval and pre-modern times, parts of the region were controlled by local chieftains and forts such as Vijaygarh and Agori served as strongholds.
During the colonial period, the area lay within the Mirzapur district of the United Provinces. The headquarters town Robertsganj is named after a British administrator. Post-independence, the region became central to India's energy infrastructure with the building of the Rihand Dam, completed in 1962.
Administration
The district is part of the Mirzapur division. It is divided into administrative tehsils including Robertsganj, Ghorawal, Dudhi, and Obra. Sonbhadra sends representatives to the Uttar Pradesh Legislative Assembly from constituencies such as Robertsganj, Ghorawal, Obra and Duddhi, the last of which is reserved for Scheduled Tribes. The district falls within the Robertsganj Lok Sabha constituency.
Economy and industry
Sonbhadra is one of the most industrialised districts in Uttar Pradesh, with its economy heavily dependent on mining and power generation.
- Thermal power: Major plants include the Anpara Thermal Power Station (operated by UPRVUNL), Obra Thermal Power Station, the NTPC Singrauli Super Thermal Power Station at Shaktinagar, and the Rihand Super Thermal Power Project at Bijpur.
- Hydroelectric power: The Rihand Dam houses a hydroelectric station managed by UPRVUNL.
- Mining: The district has significant deposits of coal, bauxite, limestone, dolomite and other minerals; Northern Coalfields Limited operates nearby in the Singrauli coal belt.
- Heavy industry: Hindalco Industries operates an aluminium smelter and captive power plant at Renukoot, and Kanoria Chemicals has a long-standing presence in the district.
Demographics
According to the 2011 Census of India, Sonbhadra had a population of approximately 1.86 million. The district has a notable tribal population, with communities such as the Gond, Kharwar, Baiga, Panika and Chero, particularly concentrated in the Dudhi tehsil. Hindi is the principal language, while Bhojpuri and tribal dialects are also widely spoken.

Significance
Owing to its concentration of coal-based and hydroelectric generation capacity feeding the northern grid, Sonbhadra is often described as the "energy capital" of India. At the same time, the district is a focus of debates around displacement, tribal land rights, and environmental concerns linked to mining and thermal power generation.
