Watanabe Floral, a family-operated kama‘aina company, has installed the first Stem Inc. energy storage system on the Hawaiian Electric Company grid to reduce business costs and help support grid stability as distributed solar generated electricity increases. Watanabe Floral has entered into a standard interconnection agreement with Hawaiian Electric to connect its new 36-kilowatt energy storage system to the grid. This project is part of a larger $2.1 million pilot program supported by Energy Excelerator, a program of the Pacific International Center for High Technology Research (PICHTR), Stem and Hawaiian Electric.
