Abstract
This Energy Insights Report profiles seven case studies that show how energy
storage can cost-effectively defer T&D asset upgrades and provide grid support.
Despite the potential of electric energy storage to improve the reliability and
efficiency of the energy delivery network, utilities have been slow to adopt
energy storage. This may be changing, at least at the distribution level. Some
utilities are beginning to implement energy storage solutions that use vanadium
redox batteries (VRB), sodium-sulfur batteries, flywheels, ultracapacitors, and
other technologies to solve issues that might have traditionally been addressed
by investment in conventional generation, transmission, or distribution assets.
