This Energy Insights report evaluates advanced stationary energy storage technologies and a number of the real-world projects in which they are either being tested or commercially operated in the United States. Utility-scale advanced energy storage systems are increasingly being deployed to solve issues that might traditionally be addressed by investment in conventional generation, transmission, or distribution assets. Recent sector developments are, in fact, spurring evolutionary technical advances, gradually helping to shift the utility mindset. Still, economic and performance-related advances must further accrue for advanced energy storage to become a utility implementation priority.
"New markets, such as frequency regulation, are opening to advanced energy storage systems, helping to drive innovation in the segment," says Sam Jaffe, Energy Insights senior research analyst. "Coupled with rising utility demonstrations and continued R&D activity, we expect advanced energy storage to play an increasingly prominent role on the energy delivery network."
