Grid-scale energy storage report covers

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, and will jeopardize the transformational changes envisioned for a modernized grid.

Recognizing the promise and urgent need for electrical energy storage technologies, the U.S Department of Energy sponsored the development of Electric Power Industry Needs for Grid-Scale Storage Applications and Advanced Materials and Devices for Stationary Electrical Energy Storage Applications. Both reports outline the high-priority initiatives that are necessary to advance the deployment of grid-based energy storage devices today through 2030.

Nexight Group worked closely with The Minerals, Metals & Materials Society; the U.S. Department of Energy’s Office of Electricity Delivery and Energy Reliability, Advanced Research Projects Agency-Energy (ARPA-E), and the Solar Technologies Program; Sandia National LaboratoriesPacific Northwest National Laboratory; energy storage device developers; and key stakeholders in the electric power industry to prepare these reports.

Electric Power Industry Needs for Grid-Scale Storage Applications identifies five storage applications that have the greatest overall potential to benefit power system planning and operations: area and frequency regulation, renewables grid integration, transmission and distribution upgrade deferral and substitution, load following, and electric energy time shift. The report also specifies quantitative performance targets that energy storage systems must achieve to realize significant market uptake across the electric grid.

Advanced Materials and Devices for Stationary Electrical Energy Storage Applications discusses the technology-specific limitations of existing energy storage offerings. The report provides timelines of technology-specific initiatives that are needed to enable energy storage devices to achieve the performance needs of the electric power industry.

In July 2010, Nexight Group conducted a series of structured telephone interviews and led two back-to-back workshops with key stakeholders in the electric power industry, academia, and the energy storage industry. Using this input and continuous feedback from our project collaborators, we drafted and finalized the energy storage reports. Ross Brindle, Nexight Group’s Executive Vice President, led the project effort. Sarah Lichtner, Technical Writer and Editor at Nexight, was the lead author of both reports.

“The widespread integration of energy storage technologies is critical for meeting the future energy needs of the United States,” said Ross. “But the challenges are so complex and diverse that no one organization has the knowledge, tools, and resources to solve it alone. Issues like this are precisely where our proven techniques add the most value. Our ability to apply successful collaborative planning models, combined with our technical, business, policy, and communications expertise, allowed us to develop these important reports.”

These energy storage reports will guide future DOE energy storage program planning and better align the energy storage community as it pursues the vision of widespread energy storage on the U.S. electric grid.
