Adani Green Energy has topped Energy Intelligence’s Annual Global Top 100 Green Utilities Rankings, underscoring the accelerating and increasingly market-driven global shift towards low-carbon electricity generation.
India’s renewable leader climbs to the top
The renewable energy arm of the Adani Group moved up from third place last year to claim the top position, overtaking China National Nuclear Corporation, which slipped to fourth. The ranking reflects strong growth in Adani Green Energy’s renewable portfolio and improving emissions performance.
According to Adani Group’s chief financial officer Jugeshinder Singh, the global energy transition is no longer driven solely by policy mandates but increasingly by sound economics, as renewable power has become a viable and competitive supply option.
Asia emerges as the centre of energy transition
The latest rankings signal a decisive shift in the global energy transition towards Asia. Half of the top ten companies are based in Asia, including two Indian and three Chinese firms, while European companies account for the remaining positions.
Adani Green Energy is among six Indian companies featured in the top 100, a sharp rise from just one Indian firm included when the rankings were first launched in 2011.
Lower emissions and rapid capacity growth
Energy Intelligence reported that carbon dioxide emissions from generators in the ranking declined by 6% in the previous year. While this drop was smaller than the 9% reduction seen in 2023, it exceeded the annual average decline of 3%–4% recorded over the preceding decade.
Since the inaugural 2011 ranking, the combined non-hydro renewable capacity of the top 100 companies has expanded dramatically to 1,079 GW, representing 29% of total installed capacity, compared with just 116 GW or 4% originally.
Renewables drive cost-effective power generation
Energy Intelligence’s managing editor James Cockayne highlighted that power companies worldwide are increasingly prioritising wind and solar investments, as these technologies now offer the lowest-cost option for new generation capacity.
He noted that Asia’s growing dominance in the rankings reflects the region’s leadership in scaling renewable energy, signalling a structural shift in the global power sector.
Methodology behind the rankings
The Top 100 Green Utilities list evaluates leading global power generators based on renewable energy capacity and carbon dioxide emissions per megawatt hour. Rather than comparing countries, the ranking assesses individual companies across both developed and emerging markets, offering a company-level view of progress towards decarbonisation.
