A123 Energy Solutions yesterday announced the first commissioning of its Long Duration grid storage system in Hawaii for the Maui Electric Company (MECO). The energy storage installation can provide 1MW for up to one hour and will perform services to increase electric grid operational efficiency, stability and power quality.
Installed at an existing MECO substation, the 1MWh energy storage system was packaged in a 20-foot container and shipped to the site fully assembled and tested. A123 Energy Solutions provided the engineering, procurement, construction, installation and testing.
A key component of the Maui Smart Grid Project, the battery will provide peak-load shifting, voltage regulation, reactive power support and wind curtailment relief. “This installation is the second site we’ve commissioned on the island of Maui in the past five months,” said Bud Collins, President of A123 Energy Solutions.
“But while the 11MW commissioned in December of last year was comprised of our widely deployed High Rate systems, this is the first time we’ve commissioned the Long Duration product. We’re very happy with how smoothly the installation went. The entire process took about five weeks from start of construction up to the completion of commissioning.”
