Demand response was the original distributed energy resource. In its early days, it was surprisingly manual: a grid operator would call up a large load, like a factory, and request a few hours of reduced demand during peak times. Fast forward to today and DERs look dramatically different. They’re automated, deployed frequently across the country, a…

Adding flexibility to data center loads could ease strain on the grid and reduce the need for costly new generation. And, according to one study, shaving off just a few megawatts during peak hours could also unlock unused capacity —as many as 98 gigawatts in the U.S — if those facilities reduced load by just 0.5% each year. The problem: data center…

The job of an EV battery is unforgiving. If its performance slips too far — say, lost acceleration or range — it's probably off to the recycling heap. That’s even though it may have plenty of usable life, if only for something less demanding than powering a vehicle. Grid storage is theoretically a gentler job, involving slower discharging and more …
