Targeted demand response reduces price volatility of electric grid
To reduce the energy load during supply constraints on the Texas power grid, it is not necessary to reduce the energy load in high population centers such as Houston and Dallas. Instead, when supply is strained, focusing on a few strategic locations across the state outside of those high-population areas is much more cost-effective and can have a greater impact on the price volatility of the grid.

Green Rare-Earth Recycling Goes Commercial
Rare earths are essential ingredients in the magnets that power many technologies people rely on today, such as cell phones, computers, electric vehicles, and wind turbines. Researchers have developed a novel way to extract rare earth elements (rare earths) from the high-powered magnets in electronic waste (e-waste).

Ultrafast Devices to Protecting the Grid from EMPs
Scientists from Sandia National Laboratories have announced a tiny, electronic device that can shunt excess electricity within a few billionths of a second while operating at a record-breaking 6,400 volts — a significant step towards protecting the nation’s electric grid from an electromagnetic pulse.

Texas Cold Snap Highlights Need for Improved Power Systems
The greatest demand for electricity in Texas is traditionally during the hottest days of the year, when air conditioners turn on full blast to beat the heat. But in February 2021, an unusually long spell of cold weather took the region by surprise. With extreme weather events rising in frequency, the need for a prepared modern energy grid grows.

Armored Transformer Barrier Protects Electric Power Grid
A 2013 sniper attack on an electric power substation in Northern California, which caused more than $15 million in damages and destroyed 17 transformers, led researchers to develop a novel protective solution: the Armored Transformer Barrier system.

We Need Hydropower for a Resilient Grid
The shift in power source mix and climate change-driven natural disasters make America’s most critical piece of energy infrastructure—the grid—more vulnerable than ever before. That’s where hydropower plays a pivotal role: When other types of power plants go dark, hydropower provides a fast, crucial response in seconds.

Pan-European “Supergrid”' Could Cut 32% from Energy Costs
A European wide ‘supergrid’ could cut almost a third from energy costs according to a new study finds. The 32% cost reduction identified is borne primarily from the expansion of European power flows - derestricting them to allow the location of renewable generation to be optimized, thereby significantly decreasing the total installed capacity.

Texas Energy Regulators, Gas Industry Try to Reassure the Public That the State’s Power Grid Is Ready for Winter
As state regulators and the companies that power the grid take steps to avoid another catastrophe like February’s winter storm, climate experts say this winter will likely be milder.

Balance of Power—Building a Resilient Electric Grid
Events such as blackouts and outages are increasing in frequency as the nation’s infrastructure ages and climate change leads to extreme weather events. Hotter, wetter summers and harsher winters require more reliance on heating and cooling utilities, placing higher stress on the nation’s electric grid. Newtechnology can ‘help keep the lights on’ during emergencies.

Microgrids May Hold the Key to Grid Resilience
The aging energy grid is being pushed to the breaking point. Power outages from extreme weather alone cost anywhere from $2 billion to $77 billion per year. And some isolated communities still rely on diesel generators for electricity, since powerlines don’t reach them. Grid expansion isn’t an option—in most cases, the economics don’t make sense. When the main grid falls short, the right mix of renewables offers local, low-carbon power.

Big Batteries on Wheels: Zero-Emissions Rail While Securing the Grid
Trains have been on the sidelines of electrification efforts for a long time in the U.S. because they account for only 2 percent of transportation sector emissions, but diesel freight trains emit 35 million metric tons of carbon dioxide annually and produce air pollution that leads to $6.5 billion in health costs, resulting in an estimated 1,000 premature deaths each year. Researchers show how battery-electric trains can deliver environmental benefits, cost-savings, and resilience to the U.S.
