Behind-the-Meter Storage Consortium

As part of the Behind-the-Meter Storage (BTMS) Consortium, NREL is working with other national laboratories to develop energy storage technologies for stationary applications below 10 megawatt-hours.

Funded by the U.S. Department of Energy's Vehicle Technologies Office, the Buildings Technologies Office, and the Solar Energy Technologies Office and led by NREL, the consortium also includes Argonne, Idaho, and Sandia national laboratories.

Research

BTMS research targets the development of innovative critical-material-free energy storage technologies to minimize the need for significant upgrades to the electric grid. Such technologies could also eliminate excess demand charges that electric vehicle fast charging would incur using current technologies.

This work leverages battery storage solutions that can discharge at high power but recharge at standard lower-power rates—essentially acting as power reservoirs bridging the gap between the grid and on-site energy generation technologies such as photovoltaics.

Employing state-of-the-art research facilities at the national labs, the consortium conducts early-stage research spanning three key areas:

• Critical-materials-free battery chemistries
• Energy generation and building integration concepts
• Stationary energy storage designs and strategies that balance performance and cost for fast-charging networks and minimize the need for grid improvements.
