For much of the past four decades, energy efficiency has been the focus of electricity cost-saving initiatives. We have changed light bulbs, swapped out old appliances, insulated our buildings, and added solar systems. The efficiency gains have slowed, however, and the next savings frontier will come from power efficiency. Through a combination of distributed energy storage and sophisticated software, our society can control power more efficiently and increase utilization of trillions of dollars of grid assets already in place. Intelligent energy storage can reduce the stress on our electric grid while helping businesses save money on their monthly electric bills.
