The biggest renewable energy projects around the world

From a gigantic hydroelectric dam in China to a solar development project covering 84 hectares in Nigeria, renewable power projects around the world are adding considerable capacity to the grid. Using data from Timetric, we profile the top 10 largest projects around the world by power generation capacity

Baihetan Hydroelectric Power Plant, China: 16,000MW

The Baihetan Dam is a large hydroelectric dam under construction on the Jinsha River, a tributary of the Yangtze River in Sichuan and Yunnan provinces in southwest China. The facility, which will have a total generation capacity of 16,000MW from 16 units of 1,000MW each, will be the second largest hydroelectric power plant in terms of generating capacity in the world, after the Three Gorges Dam in China.


Construction on the project, which is owned by China Three Gorges Project Corporation, is expected to be complete in 2021, at a total cost of $13.1bn.

Karnali Chisapani Multipurpose Dam, Nepal: 10,800MW

The Karnali Chisapani multipurpose dam project, which is located on the Karnali River in Nepal, involves the construction of a 270m high rock fill main dam with an installed capacity of 10,800MW. Once completed, the project will be the largest multipurpose project in the sub-continent, and will provide incremental irrigation benefits to India.

Owned by the Department of Electricity Development, the project was first proposed in 1986, with a feasibility study completed by Himalayan Power Consultant in 1989. As of June 2018, planning activities for the multipurpose dam were underway.

Tapajos Hydropower Complex, Brazil: 10,682MW

Brazilian energy company Eletrobras is planning to undertake the construction of a 10,682MW hydroelectric power plant along the rivers Tapajos and Jamanxim in the northern Brazilian state of Para. The project involves the construction and operation of five power plants in the Madeira basin.


With an estimated investment of $16bn, the Tapajos hydropower project is part of Brazil’s 2020 Energy Expansion Decennial Plan, which estimates a total $53.9bn investment in hydropower generations projects across the country. Technical and feasibility study activities are currently underway.

Solar Power Development, Nigeria: 10,000MW

High Quality Marketing & Consulting Korea (HQMC) is planning to develop a 10,000MW solar farm in Nigeria.

The project involves the construction of substations, access roads, control rooms, administrative buildings and related facilties on 84ha of land, as well as the installation of modules, generators, transformers and plant equipment.



With a total investment of $30bn to be spread over a 10-year period, the project is expected to create around 10,000 jobs during operation, with an estimated $1.8bn to be generated annually from the installations.

Mariah Wind Farm, US: 10,000MW

Scandia Wind Southwest’s Mariah wind farm project is being developed at Panhandle, Carson County, in Texas, US. The purpose of the project is to generate electricity through clean and renewable sources and enhance the power generation capacity of the state to meet the growing demand for power.


The 10,000MW project will be developed in three phases: the first phase will create 2,200MW of power generation; the second phase will add 2,800MW; while the third and final stage will add 5,000MW to bring the wind farm to its total generation capacity. As of February 2018, construction works on the first phase are underway.

Solar Power Plant, Qatar: 10,000MW

Qatar Electricity and Water Company (QEWC) plans to undertake a 10,000MW solar power programme in Qatar.


The project, which will have an investment of $10m, involves the construction of power houses, substations and related infrastructure, the installation of solar panels, generators, inverters and transformers, and the laying of transmission lines.



The programme is scheduled to be completed by 2030, and is part of Qatar’s plans to catch up with neighbouring countries in the Middle East by expanding its renewable energy infrastructure.

Upper Siang Hydroelectric Power Plant, India: 9,750MW

National Thermal Power Corporation’s (NTPC) Upper Siang hydroelectric power plant will have an installed capacity of 9,750MW and will be located on the Siang River in Arunachal Pradesh, India. The $15.65bn project aims to enhance electricity production to meet expected demand of 950,000MW by 2030, utilise available natural resources, and reduce the number of frequent power cuts in the easternmost regions of India.

In October 2017, the Central Government proposed to build a 300m high dam with power generation combined capacity of 10,000MW, which would replace the previously planned project and increase its capacity. A final decision regarding this plan is yet to be confirmed, and it is facing opposition from locals.

Kayan River Hydroelectric Power Plant, Indonesia: 9,000MW

The Kayan River hydroelectric power plant is planned for the Bulungan Regency in Indonesia. The project was initially planned with a capacity of 6,080MW, however this has since been increased to 9,000MW. It will be developed in five stages, the first of which includes the construction of a 900MW power plant, comprising a 85m high dam.


The developers are currently in the process of obtaining construction permits, subject to which construction will commence. The first stage is expected to take 4-5 years to complete, with the entire project costing $17.8bn.

Bunji Hydroelectric Power Plant, Pakistan: 7,100MW

China Three Gorges Corporation is planning the construction of the Bunji hydroelectric power plant near the Diamer Bhasha Dam in Gilgit Baltistan, Pakistan on the Indus River. The aim of the project, which will have an installed capacity of 7,100MW, is to fill the electricity demand-supply gap in the region. Pakistan currently faces a daily shortage of up to 5,000MW, so this new project is part of the government’s initiative to reduce the gap in supply. As of June 2018, planning activities for the $13.5bn project were underway.

East Anglia Offshore Wind Farm Development, UK: 7,114MW

The East Anglia Offshore Wind Farm project involves the construction of an offshore wind farm to generate 7,114MW of renewable energy, off the coast of Norfolk and Suffolk, UK. The site of the $35bn project, which is being developed by a consortium of ScottishPower Renewables and Vattenfall, was chosen because of excellent wind resources and existing power transmission availability. Upon completion it will be able to provide around 8,400 homes with clean energy, and will displace over 75,000 tonnes of carbon dioxide.


In July 2018, the ground breaking ceremony was held on the O&M building. The first phase of the project, known as East Anglia One, includes the installation of 102 Siemens 7MW turbines. Planning activities on East Anglia Two are currently underway.
