The electricity grid is set for a major transformation – arguably one of its biggest since the inception of the grid – and energy storage is going to play a center stage role. The radical pace of innovation is driven by governments, utilities and energy companies whose understanding and acceptance that the way energy is generated and distributed has changed, and is continuing to change at an increasingly rapid rate. With renewable energy now a major part of the mainstream grid and the drive to move away from nuclear and fossil fuels, it is clear that energy storage is the missing link.
This expanded role for energy storage began with the mandates issued by the California Public Utilities Commission (CPUC), who regulate the publicly-owned utilities that deliver over two-thirds of total electricity demand in that state. These policies require adoption of procurement targets for utilities to acquire viable and cost-effective energy storage.
