In the renewable energy section today we take a look at the best hydroelectric power plants in the world.  


5: Tucurui Dam, Brazil

The Tucurui Dam is a concrete gravity dam on the Toncantins River in the state of Para, Brazil. The main purpose of the dam is hydroelectric power production and navigation and it is the first large-scale hydroelectric project in the Brazilian Amazon rainforest. The capacity of the dam is 8,370 megawatts. It was opened in 1984.


4: Guri Dam, Venezuela

The Guri Dam is a concrete gravity and embankment dam in Bolivar State, Venezuela on the Caroni River. It was built from 1963 to 1969 and is 7,426 metres long and 162 m high.


3: Xiluodu Dam, China

The Xiluodu Dam Is an arch dam on the Jinsha River in China. It is near the town on Xiluodu in Yongshan County. The main purpose of the dam is hydroelectric power generation and its power station has an installed capacity of 13,860 MW. The dam also provides flood control; silt control and its regulated water releases are intended to improve navigation downstream. Work on the dam started in 2005 and was completed in 2013. It is currently the third-largest power station in the world.


2: Itaipu Dam, Brazil

The Itaipu Dam is a hydroelectric dam on the Parana River located on the border between Brazil and Paraguay. It was completed in 1984 has an installed generation capacity of the plant is 14 GW and 20 generating units providing 700 MW each with a hydraulic design ahead of 118 meters. In 2013, the plant generated around 75 percent of the electricity used by Paraguay and 17 percent used by Brazil.


1: Three Gorges Dam, China

The Three Gorges Dam is a hydroelectric dam that spans the Yangtze River by the town of Sandouping. It is the world’s largest power station in terms of installed capacity (22,500MW). In 2014, the dam generated 98.8 TWh of electricity, setting a new world record.

Drax advances biomass strategy with Pinnacle acquisition

Drax is advancing biomass following Pinnacle acquisition it reported in a trading update

Drax' recently completed acquisition of Pinnacle more than doubles its sustainable biomass production capacity and significantly reduces its cost of production, it reported in a trading update.

The Group’s enlarged supply chain will have access to 4.9 million tonnes of operational capacity from 2022. Of this total, 2.9 million tonnes are available for Drax’s self-supply requirements in 2022, which will rise to 3.4 million tonnes in 2027.

The £424 million acquisition of the Canadian biomass pellet producer supports Drax' ambition to be carbon negative by 2030, using bioenergy with carbon capture and storage (BECCS) and will make a "significant contribution" in the UK cutting emissions by 78% by 2035 (click here).

Drax CEO Will Gardiner said its Q1 performance had been "robust", supported by the sale of Drax Generation Enterprise, which holds four CCGT power stations, to VPI Generation.

This summer Drax will undertake maintenance on its CfD(2) biomass unit, including a high-pressure turbine upgrade to reduce maintenance costs and improve thermal efficiency, contributing to lower generation costs for Drax Power Station.

In March, Drax secured Capacity Market agreements for its hydro and pumped storage assets worth around £10 million for delivery October 2024-September 2025.

The limitations on BECCS are not technology but supply, with every gigatonne of CO2 stored per year requiring approximately 30-40 million hectares of BECCS feedstock, according to the Global CCS Institute. Nonetheless, BECCS should be seen as an essential complement to the required, wide-scale deployment of CCS to meet climate change targets, it concludes.
