Battery storage

Duke Energy is testing a hybrid ultracapacitor-battery energy storage system (HESS) at its Rankin Substation in Gaston County, N.C., in an effort to find a more effective way to integrate renewable energy into its system. The project became operational in February, but there is still testing in progress to demonstrate the system’s multiple service applications. […]

Battery storage firms and energy storage experts at the Energy Storage North America (ESNA) conference in San Diego Oct. 13–15 were effusive in their praise of battery storage’s potential while

The German battery storage market took a leap forward as German generating company Steag announced on Nov. 4 that it will invest €100 million in six 15-MW battery storage projects at several of its power plants in Germany. The batteries are expected to come online mid-2016 through early 2017. The facilities will be sited at Steag’s generating […]

Battery storage has emerged from the fringes of the power sector to challenge both industry conventions and traditional generation. Where it goes from here, however—the future of battery storage technology—is a matter of some debate. Both storage firms and energy storage experts at the Energy Storage North America (ESNA) conference in San Diego Oct. 13-15 […]

Falling prices and technological improvements have brought battery storage systems into direct competition with traditional distributed generation, demand response, and peaking generation resources. But making one work efficiently and profitably is not just plug and play.   Last fall, Southern California Edison (SCE) had some big decisions to make. The giant utility, which serves 14 […]
