The Smart Electric Power Alliance (SEPA), formerly the Solar Electric Power Association, has summed up the role of energy storage in two words — grid empowerment — and has wisely stated that no matter how you consider the evolution of distributed energy, it is clear that energy storage technologies will play an integral part in the growth of a clean energy ecosystem for decades to come, since energy storage delivers flexibility, range and responsiveness to smart grids.
Utilities across the nation are realizing the potential of this versatile technology and deploying it in unique ways. From community solar arrays to microgrids, customer-sited energy storage and electric vehicle charging stations, utilities and businesses are finding new and creative ways to harness this smart energy technology.
Given the strong synergies between energy storage and solar power, SEPA has released its annual top ten rankings for utilities based on key energy storage measures, along with its widely-publicized top ten lists for utility solar power. These annual lists, released at the Utility Solar Conference in Tucson, Arizona, recognized a select group of U.S. utilities for solar connections and energy storage connected to the grid in 2016.
