Reliable access to cost-effective electricity is the backbone of the U.S. economy, and electrical energy storage
is an integral element in this system. Without significant investments in stationary electrical energy storage, the
current electric grid infrastructure will increasingly struggle to provide reliable, affordable electricity, jeopardizing the
transformational changes envisioned for a modernized grid. Investment in energy storage is essential for keeping
pace with the increasing demands for electricity arising from continued growth in U.S. productivity, shifts in and
continued expansion of national cultural imperatives (e.g., the distributed grid and electric vehicles), and the projected
increase in renewable energy sources.
