Global Large-Scale Solar Capacity Hits 1 TWac Milestone
⚡ Quick Read
- What happened: Global utility-scale solar capacity (projects 4 MWac+) has officially crossed the 1 TWac threshold, reaching 1,008 GWac across 33 leading nations.
- Why it matters: India maintains its position as the world’s third-largest market with 109.6 GWac, signaling massive ongoing opportunities for domestic EPCs and developers.
- Watch: Industry experts project that utility-scale solar capacity will match global wind power installations by the end of 2026.
Background and Context
The global energy transition has reached a historic inflection point as large-scale solar capacity surpassed 1 TWac worldwide in 2025. According to the latest data from PV consultancy Wiki-Solar, the utility-scale segment—defined as projects 4 MWac and larger—has demonstrated unprecedented growth. This analysis covers 23,285 individual projects across the 33 most significant markets, which collectively represent approximately 92% of the world’s total utility-scale solar infrastructure.
Key Details
The data reveals that 2024 was a record-breaking year for the sector, with nearly 250 GWac of new capacity added globally. China continues to dominate the landscape, holding 5,639 plants with a cumulative capacity of 446 GWac. The United States follows in second place with 162.8 GWac. India has solidified its position as the third-largest global market, boasting 1,965 large-scale solar plants with a cumulative capacity of 109.6 GWac. Other notable players include Spain (39.3 GWac), Germany (25.1 GWac), and Brazil (21 GWac).
What This Means for EPCs and Developers
For Indian EPC contractors and solar developers, these figures underscore the immense scale of the domestic market. With India holding over 100 GWac of utility-scale capacity, the local supply chain and project execution capabilities are among the most robust in the world. The shift toward larger, more complex projects—including those integrated with battery energy storage systems (BESS)—presents a clear growth trajectory. As Wiki-Solar transitions its platform to ‘RenewAtlas’ to track over 30,000 projects, developers should leverage such data-driven insights to identify emerging trends in hybrid energy configurations and site optimization.
What Happens Next
Philip Wolfe, founder of Wiki-Solar, anticipates that utility-scale solar will match global wind power capacity by the end of 2026. Furthermore, he predicts that solar will emerge as the world’s primary energy source within the next two decades. For the India renewable energy sector, this growth reinforces the government’s ambitious targets for net-zero emissions. As the market matures, the focus will likely shift from pure-play solar to integrated, dispatchable renewable energy solutions, ensuring that India remains a central pillar in the global decarbonization roadmap.
