Smart grid energy storage: European "battery parks" show a path ahead
By: SGN Staff
Quick Take: The future of grid-scale energy storage continues to come into sharper focus. I recently told you about AES and its "operating system" for storage. AES illustrates two keys to making grid-scale storage mainstream. The first is a "platform" for storage that is battery agnostic - that allows you to swap in any brand or type of battery without redoing your software. The second is multiple value streams - putting a single stack of batteries to work in many different ways.
Navigant Research is now out with a story of some German battery parks that show one way to accomplish the second concept. - By Jesse Berst
Berlin-based microgrid vendor Younicos recently deployed a 1.2 MW "battery park" in Berlin for the Swedish utility Vattenfall. The project uses both sodium sulphur and lithium ion batteries, according to Peter Asmus of Navigant Research. In 2014, the firms will launch a second project, a standalone 5 MW/5 MWh battery park in Germany for WEMAG, a municipal utility.
The second battery park will be able to help regulate grid frequency, provide voltage control, black starts and short circuit power. It can respond in less than 10 milliseconds, 3,000 times faster than conventional approaches.
The lithium ion batteries are supplied by Samsung, part of an agreement between the two to build grid-scale storage in Germany, Austria, Switzerland, and other European markets. Samsung offers a 20-year performance guarantee.
