Utilities and other electricity and transmission providers and regulators often require that equipment be proven safe and reliable before it is permitted on the grid. However, energy storage manufacturers and integrators are often unable to afford or provide the logistics necessary for this long-term testing and monitoring. 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.

Sandia’s ESTP and ESAL can provide users the venue for testing and validation in either a direct grid connection or using a simulated charge-discharge protocol that, accompanied by detailed diagnostics and analysis, can provide verification of a storage device’s reliability.
With the capabilities of the ESTP, ESAL and their staff, users can analyze system performance relative to standards and applications, develop new testing procedures, and support development of new energy storage standards. Sandia’s battery testing facilities are supported by extensive resources across Sandia for battery development, characterization, materials analysis, and abuse testing, providing a full array of expertise and capabilities to aid with battery testing and evaluation as well as R&D activities.

The ESTP and ESAL can test energy storage devices to manufacturers’ specifications through characterization and application specific cycle testing. These include both power and energy applications such as: energy time shift, capacity, load following, area regulation, voltage support, T&D deferral, demand charge management, and power quality. They can also help users evaluate system parameters including storage device efficiency, performance to specifications, reliability, and balance of plant operation.
