Unit of Chinese firm installs energy storage tech in Hawaii

A123 Energy Solutions of China’s Wanxiang Group installs battery system to stabilise power grid on Hawaiian island Maui

The installation is A123 Energy Solutions’ second energy storage system for the island of Maui in five months

Energy storage technology from a unit of a Chinese firm has been installed in the US state of Hawaii. The energy storage system, which A123 Energy Solutions, a unit of China's Wanxiang Group, has developed, will stabilise the power grid on the Hawaiian island of Maui.

A123 Energy Solutions, which is a developer and manufacturer of advanced energy storage systems, said the news marks the first commissioning of its Long Duration (LD) Grid Storage Solution in Hawaii for the Maui Electric Company (MECO). The installation is also the second site A123 Energy Solutions has commissioned on the island of Maui in the past five months.

Installed at an existing MECO substation, the energy storage installation can provide 1MW for up to one hour. It will perform services to increase electric grid operational efficiency, stability, and power quality. 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.

For the storage project, A123 Energy Solutions provided a turnkey solution to MECO, performing the engineering, procurement, construction, installation and testing for the system. The 1MWh energy storage system was packaged in a 20-foot container and shipped to the site fully assembled and tested.

Bud Collins, president of A123 Energy Solutions, said: "This installation is the second site we've commissioned on the island of Maui in the past five months. 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."
