Energy Storage

South Africa’s power system is preparing to receive a critical capacity boost. In March, state-owned utility Eskom grid-synchronized the first of four units of the Ingula Pumped Storage project in

It’s not being overly dramatic to say that the power industry is at its biggest inflection point to date. Even ignoring the effects of environmental regulations and (in North America, at least) cheap natural

Getting the most cost-effective use out of a battery storage system isn’t just a matter of plug-and-play. Where and how you site a battery can make a big difference in how well it does its job. Several battery experts who spoke to POWER explain what you need to think about. So you want to buy […]

Executives from power companies operating in different markets revealed how their firms are being affected by low natural gas prices, pressures to achieve fuel diversity, distributed energy generation, and lax demand growth, among a number of topics. The annual executive roundtable panel at the ELECTRIC POWER Conference and Exhibition on April 19 was moderated by […]

By an 85-12 vote, the U.S. Senate passed the first comprehensive energy bill in nearly a decade, bringing a successful conclusion to months of legislative effort and overcoming a series of roadblocks in the full Senate related to the water quality crisis in Flint, Mich. The product of more than a year of bipartisan work […]

Saudi Arabia Mulling Privatization of State-Owned Utility. State-controlled Saudi Electricity Co. (SEC) is to be split into four power generation firms by the end of 2016 to increase efficiency, Abdullah

Whether utilities, technology providers, or independent third-party upstarts are best suited to create a reliable recipe for microgrid development remains an open question.

Although new microgrid configurations, technologies, and business models are still evolving in the U.S., some lessons have been learned in the past few years. Aside from the fact that financing nontraditional/non-campus microgrids is hard, if there’s one overarching lesson, it’s that a microgrid designed to provide only one benefit or rely on only one generation source is unlikely to succeed.

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. […]

Desert sand from the United Arab Emirates could be used in concentrating solar power (CSP) facilities to store thermal energy up to 1,000C. And replacing the typical heat storage materials used in thermal
