U.S. power grid needs to focus on resilience as extreme weather events rise- NERC

U.S. power grid needs to focus on resilience as extreme weather events rise- NERC

July 20 (Reuters) – The North American Electric Reliability Corp (NERC) on Wednesday said key entities of the U.S. power grid network were working to improve resilience of the power grid network as climate change drives more extreme weather.

The NERC’s “2022 State of Reliability” report said efforts were being made to improve the linkage between outages and weather by the Enterprise Electric Reliability Organization (ERO).

The ERO is made up of the NERC and six regional power entities.

The U.S. power grid network is also implementing corrective action to avoid a repeat of widespread outages due to a cold snap last year.

“The February cold weather event demonstrated that a significant portion of the generation fleet in the impacted areas was unable to supply electrical energy during extreme cold weather,” the NERC’s report said.

These actions, based on recommendations by the Federal Energy Regulatory Commission (FERC) and NERC among others, would also help to develop standards for longer term grid planning, the NERC said.

The report also highlighted the growing risks from the inter-dependency of electricity and the natural gas industries, which has threatened the reliability of the Bulk Electric System in the past few years. The Bulk Electric System refers to the facilities needed to operate the electric energy transmission network, excluding local distribution.

Natural gas generators are now needed for the reliable integration of renewable power until new storage technology is fully developed and implemented at scale, the NERC said.

“At the same time, reliable electric power supply is often required to ensure uninterrupted delivery of natural gas to these balancing resources, particularly in areas where penetration levels of renewable generation resources are highest.”

The NERC report also flagged risks from geopolitical events, while “increasingly bold cyber criminals and hacktivists presented serious challenges to the reliability” of the bulk electric system.

BEIJING, June 28 (Reuters) – Extreme flooding that has battered southern and eastern provinces in China, leading to hundreds of thousands being evacuated and the highest rainfall in decades at the Pearl River basin, will likely continue in July and August, according to a government official.

“It is predicted that from July to August, there will be more extreme weather events in China, and regional flood conditions and drought conditions will be heavier than usual,” said Yao Wenguang, director of the Department of Flood and Drought Disaster Prevention of the Ministry of Water Resources, in an interview with Xinhua News Agency.

Images on social media, from cars trapped underwater to emergency rescues in floating rafts, reveal the widespread calamity in the country. A home collapsing into a river in Southern China recently went viral on Tik Tok.

“From late May to mid-June, there were seven consecutive heavy rainfall processes in the Pearl River Basin, with relatively concentrated and overlapping rain areas, heavy rain intensity and heavy cumulative rainfall,” Yao Wenguang said.

China has been grappling with extreme weather contrasts, with Guangdong, Fujian and Guangxi provinces experiencing record rainfall while Shandong, Henan and Hebei provinces faced scorching heatwaves, pressuring the national power grid.

Meanwhile, drought conditions are also exacerbating problems with Yao Wenguang saying, “At present, drought has emerged in some parts of northern China and developed rapidly, mainly concentrated in Inner Mongolia, Henan, Shaanxi, Gansu and other provinces and regions.”

He said in response to the drought in four provinces and regions, the Ministry of Water Resources launched a drought defense level IV emergency response on June 25, sending three working groups to stricken areas in Inner Mongolia, Shaanxi and Gansu to help with measures to fight the drought.

Extreme weather events are making headlines across the globe, with flooding in China, India and Bangladesh and heatwaves in South Asia, Europe and the United States. Many scientists and experts point to climate change as the culprit.

On Tuesday, a team of climate scientists published a study in the journal Environmental Research: Climate, looking into the role climate change has played in individual weather events over the past two decades. The findings confirm warnings of how global warming will change our world – and also make clear what information is missing. read more
