The latest trend is that power transmission companies around the world are increasingly looking at energy storage technology to defer or replace transmission system upgrades. How this works is energy storage is placed along a transmission line and operated to inject or absorb power, mimicking transmission line flows. Going with names like virtual transmission in Australia and GridBooster in Germany, projects totaling over 3 GW of capacity are poised to increase system efficiency and reliability across the world.

Energy-as-a-Service (EaaS) is emerging as an innovative approach for obtaining reliable power supply, predictability of pricing, and meeting sustainability goals. There is a growing trend among commercial and industrial (C&I) energy users preferring energy storage as-a-service (ESaaS).
