2012-3432P [181kb pdf]
The Energy Storage Test Pad (ESTP) in conjunction with the Energy Storage Analysis Laboratory (ESAL) provides trusted, independent, third party testing and validation from the cell level up to 1+ MW AC electrical energy storage (EES) systems.

In addition to long-term testing, Sandia provides pre-certification, pre-installation, and verification of EES systems.

Our goal is to develop advanced energy storage technologies that will increase reliability, performance, and competitiveness of electricity generation and transmission.


ESAL Testing

Analysis of cells to pack size modules are carried out in the ESAL.

  • Cell level
  • Module
  • Pack level
  • Slots available at different power levels for concurrent testing
  • Reconfigurable command and control to simulate various use cases
