India's energy investment is set to reach a record USD 170 billion in 2026, driven by rapid expansion in solar power and oil refining as the country accelerates efforts to meet rising energy demand and strengthen infrastructure for its clean energy transition. The International Energy Agency (IEA), in its World Energy Investment 2026 report, said energy investment in India has grown at an average annual rate of 11 per cent over the past five years, with solar photovoltaic (PV) investment rising 25 per cent annually and oil refining investment growing 23 per cent over the same period. Together, the two sectors accounted for roughly a quarter of the increase in overall energy spending.
