The International Energy Agency (IEA) projects that India’s total energy investment will reach a record $170 billion in 2026, supported by rapid infrastructure expansion as demand rises. In its World Energy Investment 2026 report, the IEA says investment in India has increased by an average of 11% per year over the past five years. Growth is particularly strong in solar and refining: solar photovoltaic (PV) investment is reported to be rising at about 25% annually, while oil refining investment is increasing by around 23% annually. Combined, these two sectors account for roughly one quarter of the increase in overall energy spending. The IEA also links investment to broader grid and storage build-out, noting expansion efforts that include transmission and battery storage infrastructure. On refining, the report says India is on track to expand refining capacity by nearly 15% by 2030, even though the country remains heavily dependent on imported crude oil. The sources also indicate that upstream oil and gas investment is not growing at the same pace, with upstream spending contracting on average in recent years.
