A recent study by the U.S. National Renewable Energy Laboratory (NREL) reveals that floating solar (FPV) on U.S. reservoirs could provide up to 1 terawatt (TW) of generation capacity.

A recent study by the U.S. National Renewable Energy Laboratory (NREL) reveals that floating solar (FPV) on U.S. reservoirs could provide up to 1 terawatt (TW) of generation capacity. The study estimates that between 861GW and 1,042GWdc of FPV could be deployed across U.S. reservoirs, potentially generating up to 1,476TWh of electricity. It is conservatively estimated that 861GW of FPV capacity could contribute over half of the 1.6TW of solar PV capacity required to decarbonize the U.S. grid by 2050.
Parallel research from the Idaho National Laboratory has identified 849 U.S. reservoirs with the potential to host FPV projects. Among these, the Salton Sea in California stands out with a potential capacity of 76.6GW. Other states with high FPV potential include Texas (137GW), California (102GW), and Oklahoma (84GW).
In related news, Ciel & Terre has completed a 20MW FPV project in eastern France, the largest in the region, using its aiR Optim technology to improve plant efficiency and reduce maintenance.

Baota Mountain Converter Station's AC System Energized, Marking Key Milestone in UHV Project

On February 5, the AC system of the Baota Mountain Converter Station, the sending - end station of the ±800 kV North Shaanxi - Anhui UHV DC power transmission project, was successfully energized for the first time. This marks that the AC system of the converter station has entered the startup commissioning stage, and the entire AC system of the project is expected to be put into operation before the Spring Festival. It is reported that the rated voltage of the North Shaanxi - Anhui UHV project is ±800 kV, with a rated capacity of 8 million kilowatts, and a dynamic investment of 20.5 billion yuan. The project starts from the Baota Mountain Converter Station in Yan'an City, Shaanxi Province, and ends at the Hezhou Converter Station in Hefei City, Anhui Province. It passes through three provi

World's First Multi-Source DC Project in Jiangsu Completes Phase II, Boosts Cross-River Power Transmission

On February 12, the second - phase project of the ±200 kV DC power transmission project from Yangzhou to Zhenjiang in Jiangsu, which is the world's first multi - source commutated DC power transmission project and China's first AC - DC hybrid cross - river project, was completed and put into operation. The project's transmission line is about 228 kilometers long, with a transmission capacity of 1.2 million kilowatts. It passes through three cities (Huai'an, Yangzhou, and Zhenjiang) and seven counties. Among them, a 47 - kilometer new - built DC transmission line is erected on the same tower as the 500 kV AC line, and two new converter stations are built. Without adding a new cross - Yangtze - River power transmission channel, the original cross - river power transmission capacity has been

Shaanxi Boosts Power Capacity to 127GW, Invests in Grid and Renewable Energy Growth

It is learned that Shaanxi Province's power generation installed capacity has increased from 72.75 million kilowatts in 2020 to 127 million kilowatts in 2025, with the installed capacity of renewable energy growing by about 2.7 times. Meanwhile, the province has invested a total of 120 billion yuan to strengthen the power grid and expand transmission channels, making the power grid more robust and reliable. Statistics show that during the 14th Five-Year Plan period, Shaanxi put into operation over 10 million kilowatts of clean and efficient coal-fired power generation capacity, and the scale of coal-fired power projects under construction that meet regulations reached a record high for the same period. The total scale of coal-fired power plants undergoing energy-saving and carbon-reduction
