Indian Power and Energy Sector

The refineries at Mathura (Uttar Pradesh), Digboi (Assam), and Panipat (Haryana) are all owned and operated by the Indian Oil Corporation Limited (IOCL), India's largest state-owned oil and gas corporation.

The Taj Mahal Palace Hotel, commissioned by Jamsetji Tata and opened in 1903, was indeed the first building in Bombay (Mumbai) to be electrified. This was a significant technological advancement for the time, showcasing the Tata family's commitment to modernization and innovation.

Both Tata BP Solar and Tata Power have been involved in solar power generation. Tata BP Solar was a joint venture for solar manufacturing, while Tata Power has significant solar generation capacity through its Tata Power Renewable Energy Limited (TPREL) subsidiary. The answer refers to both companies working in solar.

The Numaligarh refinery is located in Assam state, specifically in the Golaghat district. It was established as part of India's efforts to develop refining capacity in the petroleum-rich northeastern region. Assam has been famous for oil since the discovery of oil at Digboi in 1889.

India's major petroleum reserves are concentrated in Assam (upper Assam basin) and Odisha (eastern coastal basin). Gujarat has offshore reserves but they're not the 'workable' (economically viable) reserves. Assam has India's oldest and most developed onshore oil fields. Orissa (now Odisha) has significant coastal reserves.

Neyveli in Tamil Nadu is famous for its lignite deposits, which belong to the Tertiary geological period (approximately 2-66 million years ago). The Neyveli thermal power station is specifically designed to burn this lignite. Gondwana coal is much older (Permian period), while Cambrian and Quaternary are not relevant coal classifications in India.

All three locations - Haldia (West Bengal), Digboi (Assam), and Barauni (Bihar) - have oil refineries. Digboi has Asia's oldest refinery (1901), Haldia has a modern refinery, and Barauni has a major refinery in eastern India.

Koyali (near Vadodara, Gujarat) has a major public sector refinery that processes crude oil from Gujarat's offshore and onshore oilfields. The other options are located in different states and refine crude from different sources.

Western Region has the largest installed power generation capacity in India, primarily due to presence of states like Gujarat and Maharashtra with significant thermal, renewable, and nuclear power plants. Northern, Eastern, and Southern regions have lower total capacity despite having large states.

The Nathpa Jhakri Hydroelectric Project (1500 MW) on the Sutlej River in Himachal Pradesh was India's largest hydroelectric project when completed in 2004-2005. While Tehri Dam is also large, Nathpa Jhakri held the distinction of being the largest operational hydel project at the time.

Kalinga Park (TCS Bhubaneswar) received LEED Platinum certification from the US Green Building Council. LEED (Leadership in Energy and Environmental Design) is a prestigious green building certification program.

TCS's Kalinga Park in Bhubaneswar achieved LEED Platinum certification from the US Green Building Council. This was TCS's first campus to receive the highest LEED rating for sustainable building design and operations. The other parks (Yantra Park, Banyan Park, Synergy Park) are TCS facilities but Kalinga Park has this specific distinction.

The Godavari-Krishna basin in Andhra Pradesh is famous for its Oil & Natural Gas reserves, particularly in the KG Basin. This region has been a major site for hydrocarbon exploration since the 2000s. It's not particularly known for iron, copper, or uranium reserves, which are found in other parts of India.

Coal India Limited was granted 'Maharatna' status in 2011, becoming the fifth PSU after ONGC, IOC, NTPC, and SAIL to receive this elite designation. The Maharatna status gives greater operational and financial autonomy to these large, profit-making public sector enterprises.
