The Imperial Irrigation District (IID), the third-largest public power utility in California, recently issued QR 123, the first step in a solicitation for 20 megawatts to 40 megawatts of “battery” storage. The solicitation seeks storage that can accommodate a very broad range of specified operational characteristics, and it may prove challenging for any given storage technology to meet all of those characteristics. The solicitation’s reference to “battery” storage implies that IID is not seeking flywheels or other energy storage technologies.
At this stage, QR 123 is in the nature of a request for vendors to supply their qualifications to “design, engineer, procure and construct a utility-scale energy storage project” that will have the desired operational characteristics. Responses are due February 11, 2014.
