SPIC is also expanding internationally, particularly in emerging markets seeking large utility-scale renewable projects.
18. China Energy Investment Corporation
China Energy Investment Corporation is another major beneficiary of China’s enormous renewable infrastructure buildout.
Its scale across generation, engineering and infrastructure allows it to integrate wind and solar with transmission and storage — increasingly important as China adds hundreds of gigawatts of renewable capacity.
19. Statkraft — NOK16-20 Billion Annual Investment Target
Norway’s Statkraft combines hydroelectric generation with wind and solar investments.
The company has targeted approximately NOK16-20 billion of annual investment across core technologies and markets.
During H1 2026, Statkraft made investment decisions covering more than 600 MW of new renewable capacity, including projects in Peru and Europe.
20. Repsol — Renewables Exceed 6 GW
Repsol’s installed renewable capacity exceeded 6 GW in 2026, with Spain and the United States among its priority investment markets.
Major developments include the 825 MW Pinnington solar project in Texas.
Repsol is also using asset rotation to sell stakes in mature renewable projects and recycle capital into new developments, reducing the capital intensity of expansion.
Renewable Investment Race Is Moving Beyond Capacity
The biggest renewable companies are increasingly differentiated by how much capital they can deploy and how efficiently they can convert development pipelines into operating assets.
Masdar plans another $30-$35 billion through 2030. Enel’s 2026-2028 investment program totals about €53 billion, while Iberdrola plans €58 billion through 2028 across networks, renewables and customers. RWE is targeting €35 billion through 2031.
India is producing another group of fast-growing players, with Adani Green targeting 50 GW and ReNew combining renewable generation with storage and solar manufacturing.
Battery storage is becoming particularly important. ENGIE already has a multi-gigawatt storage portfolio, Adani Green is targeting more than 10 GWh in FY2027, and ReNew has 6.2 GWh in its portfolio.
Outlook to 2030
The renewable-energy leaders of 2030 may therefore look different from a ranking based purely on today’s installed GW.
The strongest companies will combine renewable capacity, multibillion-dollar investment programs, storage, electricity networks, long-term PPAs and access to fast-growing power markets.
AI data centers, electrification and industrial expansion are also creating new sources of electricity demand. This gives developers with strong balance sheets, grid connections and storage portfolios an advantage in converting renewable pipelines into commercially viable projects.
Capacity still matters. But in the next phase of the renewable-energy race, capital deployment and the ability to finance, connect and sell clean electricity may matter just as much as the number of gigawatts installed.
