Selected Large Power Plants and Energy Complexes — 2026 Source Review

This is a selected comparison of 15 large power plants, solar parks and energy complexes, using the capacity reported in each linked source. It is not an exhaustive world top 15. The 2026 label identifies this source review, completed on 17 October 2026; it is not a common observation year for every value. Historical reference dates and site boundaries are listed below.

Capacity is measured in megawatts (MW), not electricity generated in MWh or TWh. A larger rated capacity does not guarantee greater annual generation. These sources do not use a single harmonized net/gross or solar AC/DC reporting standard, so the bars provide scale comparisons rather than a precise like-for-like operational ranking.

Hydropower references. CTG reports Three Gorges at 22,500 MW, Baihetan at 16,000 MW, Xiluodu at 13,860 MW, Wudongde at 10,200 MW and Xiangjiaba at 6,400 MW; its portfolio page is undated and was checked for this review. Itaipu's operator confirms 20 units of 700 MW, totaling 14,000 MW, in its 5 May 2026 report. Eletrobras lists Belo Monte at 11,233 MW and Tucuruí at 8,535 MW. Hydro-Québec's specifications give Robert-Bourassa alone as 5,616 MW at 31 December 2022; the separate 2,106 MW La Grande-2-A station is excluded.

Parks and complexes. Talatan is a multi-company solar park: the government forestry report gives 17,730 MW connected at the end of 2024. The Ningdong entry now identifies the specific 2,000 MW Guoneng solar project, fully connected in June 2023 according to CHN Energy, rather than an undefined regional total. The wind entry covers the 51 Guazhou wind farms within Jiuquan: the Gansu government profile dated 3 April 2024 reports 11,650 MW. It does not represent all wind capacity in Jiuquan. DEWA's 20 May 2022 report gives 9,547 MW for the Jebel Ali power and desalination complex, excluding Al Aweer.

Nuclear boundary. Kori and Shin-Kori units 1–2 total 4,550 MW in KHNP's 31 December 2025 facilities table: 2,550 plus 2,000 MW. Permanently closed Kori unit 1 and the separately managed Saeul units are excluded. This is nominal listed capacity, not the output available at a particular moment.

Historical Guri reference. The archived project page of contractor HPC Venezuela gives 10,300 MW for Guri; the cited capture is from 11 November 2013. This historical contractor figure differs from the former secondary-source value of 10,235 MW. It does not establish Guri's currently available capacity. Each row links to its own source so the date and boundary can be checked before reuse.
