The world’s 20 largest power generation construction projects are worth a combined $633.7bn, led by one scheme that dwarfs the rest of the ranking.

China’s Yarlung Tsangpo Hydroelectric Power Plant tops the list by a wide margin. The 60,000MW project is valued at $167bn and is already in execution, making it more than two and a half times the size of the second-ranked scheme, the UK’s Hinkley Point C Nuclear Power Station, valued at $65.994bn.

That gap shows how a single hydroelectric megaproject can shift the shape of the global power construction pipeline.

Nuclear-related projects are the most common in the top 20, appearing 11 times when nuclear fusion and refurbishment projects are included. The list features schemes in the UK, Egypt, Poland, France, China, Bangladesh, Slovakia, Slovenia and Canada, with values ranging from $15.056bn to almost $66bn.

Renewables also make a strong showing. South Korea’s Donghae 1 Floating Offshore Wind Farm, Denmark’s North Sea Energy Island, Morocco’s Sila Atlantik Photovoltaic and Wind Power Plant, India’s Vighakot Hybrid Solar-Wind Power Storage Farm and Australia’s Newcastle Offshore Wind Farm all sit inside the ranking.

The pipeline is not only about projects already on site. Seven schemes are in execution, while the rest remain in planning, pre-planning or pre-execution. That includes major developments such as Indonesia’s $35bn Mamberamo Hydro Power Plant, the US-based Portsmouth Natural Gas Power Facility and Vietnam’s Quang Ninh LNG Power Plant.

By region, Europe accounts for eight projects and Asia for seven, with Africa, North America and Australia also represented.
