GE Renewable Energy has signed a deal that may see it perform upgrades to the 14 gigawatt Itaipu hydropower plant, an unlimited facility straddling the border between Brazil and Paraguay.

In a press release earlier this week, GE Renewable Energy stated its Hydro and Grid Solutions companies had signed a contract associated to the works, that are set to final 14 years. Paraguayan companies CIE and Tecnoedil will present help for the venture.

Among different issues, GE stated the upgrades would come with “equipment and systems of all 20 power generating units as well as the improvement of the hydropower plant’s measurement, protection, control, regulation and monitoring systems.”

In 2018, GE stated a consortium arrange by GE Power and CIE Sociedad Anonima had been chosen to “provide electrical equipment for the early stages” of the dam’s modernization venture.

Itaipu commenced electrical energy manufacturing in 1984. The web site of Itaipu Binacional says the ability “provides 10.8% of the energy consumed in Brazil and 88.5% of the energy consumed in Paraguay.”

In phrases of capability, it’s the world’s second largest hydroelectric energy plant after China’s 22.5 GW Three Gorges Dam.

According to the International Energy Agency, 2020 noticed hydropower technology hit 4,418 terawatt hours to keep up its place as “the largest renewable source of electricity, generating more than all other renewable technologies combined.”

The IEA states that just about 40% of the planet’s hydropower fleet is not less than 40 years previous. “When hydropower plants are 45-60 years old, major modernisation refurbishments are required to improve their performance and increase their flexibility,” it says. At 38, Itaipu would seem like on the cusp of this threshold.

Hydropower has its backers, however there are additionally considerations in regards to the sector’s environmental footprint.

The U.S. Energy Information Administration notes that whereas hydropower turbines could not “directly emit air pollutants” different components associated to dams, reservoirs and turbines can have an impact.

“A dam that creates a reservoir (or a dam that diverts water to a run-of-river hydropower plant) may obstruct fish migration,” it says, including that dams and reservoirs “can also change natural water temperatures, water chemistry, river flow characteristics, and silt loads.”

In addition, the EIA states reservoirs might find yourself overlaying areas together with archaeological websites and land used for agriculture. “A reservoir and the operation of the dam may also result in the relocation of people,” it says.

Toward the tip of April, GE reported that its renewables section had suffered a lack of $434 million for the primary quarter of 2022, in comparison with a $234 million loss within the first quarter of 2021. Revenues for renewable vitality have been $2.87 billion, down from $3.24 billion within the first quarter of 2021.
