Energy storage performance testing for investment confidence

This author no longer works for DNV GL.

Energy storage technologies and applications continue to advance. Yet much work is still to be done on developing policies and standards for energy storage devices and applications. So how do developers, manufacturers, and end users gain confidence in their energy storage investments?

Energy storage performance testing is a critical part of the answer. Here’s what Paul Leufkens, president of KEMA-Powertest, said:

“It is important to test at the three levels—cell and stack, system scale, and in the field up to any power level. Testing at each level of complexity helps identify and fix any weak parts in the system. It’s an integrated process to test on the small scale, see what you can do there, then derive ‘model’ rules, apply and check on system scale, and confirm at site. Ultimately, it is about the performance that a utility may expect from a system.”

KEMA has opened an energy storage performance testing lab, the first U.S. testing solution for the rapidly evolving energy storage industry. KEMA’s energy storage performance testing verifies the performance, interoperability, and integration of any energy storage system.

The testing is conducted on a single component cell or stack level through to utility-scale megawatt systems. The performance testing uses a utility grid interconnection to test large-scale systems in their desired applications for up to 2 MW, which is unique in the industry. KEMA also applies field testing up to any power level, and tests performance through any application such as renewable integration, peak shaving, and frequency regulation.

KEMA will demonstrate its energy storage performance testing services at its KEMA-Powertest facility in Chalfont on Thursday, March 3, 2011. During the day-long event, International Battery’s President and CEO, Dr. Ake Almgren, will provide the keynote presentation. In addition, KEMA will demonstrate its testing procedures on a 35kWh energy storage system supplied by International Battery.

“We commend KEMA’s efforts to offer the most comprehensive testing services for the electric energy storage industry,” said Dr. Almgren. “This level of independent testing will help assure reliability as well as the integrity of performance data of various energy storage technologies as manufacturers such as us continue to develop battery systems for a growing range of applications.”
