The US power grid quietly survived its most brutal summer yet

“Part of the reason that Texas sometimes struggles to make enough electricity is that it has a freewheeling power market with fewer interventions from regulators than those in other states. The priority is to sell electricity in real time at the lowest possible cost, with little backup margin, although that’s starting to change. Spurred by the 2021 blackout in Texas from Winter Storm Uri that cut off power to 4 million customers and killed at least 246 people, ERCOT implemented rules to encourage more reserve power on its grid.”

Consumers, not corporations, saved the power grid. What else can we do?

“when added up, thousands of small actions, like switching off lights during a heat wave, buying efficient appliances, or voting for politicians who will act on climate change, can become a larger force than what governments and businesses can muster on their own. Put another way, a comprehensive approach to climate change demands actions, both large and small.
“It’s a mistake to only focus on governments and big companies,” said Paul Burger, head of the sustainability research group at the University of Basel, who studies consumer decisions on energy. “It’s also a mistake to only focus on individuals.””

How the Western drought is pushing the power grid to the brink

“It takes a lot of water to make power.

From spinning turbines to hydraulic fracturing to refining fuel, the flow of water is critical to the flow of electrons and heat. About 40 percent of water withdrawals — water taken out of groundwater or surface sources — in the United States go toward energy production. The large majority of that share is used to cool power plants. In turn, it requires energy to extract, purify, transport, and deliver water.

So when temperatures rise and water levels drop, the energy sector gets squeezed hard. The consequences of water shortages are playing out now in swaths of the American West, where an expansive, decades-long drought is forcing drastic cuts in hydroelectric power generation. At the same time, exceptional heat has pushed energy demand to record highs. As the climate changes, these stresses will mount.

The United Nations Environment Programme warned..that if drought conditions persist, the two largest hydroelectric reservoirs in the US — Lake Mead and Lake Powell —could eventually reach “dead pool status,” where water levels fall too low to flow downstream. Lake Mead fuels the Hoover Dam, which has a power capacity topping 2,000 megawatts while Lake Powell drives generators that peak at 1,300 megawatts at the Glen Canyon Dam.”

The US power grid isn’t ready for climate change

“It’s abundantly clear that the power grid in the United States is not ready for the effects of climate change, including the extreme weather events that come with it. After all, climate change isn’t just increasing the demand for energy to keep people cool or warm amid heat waves and winter storms. It’s also damaging the grid itself. The country is now in a race against time to shift its energy supply toward renewable sources, like wind and solar, while also needing more and more electricity to do everything from powering more air conditioning to boosting the number of EVs on the road.”
