Batteries for Grid Management

This Hawai‘i Natural Energy Institute (HNEI) project is being funded by the Office of Naval Research in collaboration with the US Department of Energy (DOE). The objective is to mitigate adverse impacts of integrating intermittent renewable energy sources onto electricity grids in Hawai‘i. For this project, the technology being evaluated is a fast-response battery energy storage system (BESS). In addition to HNEI, project partners include Altairnano, Inc., Hawi Renewable Development LLC, and SCADA Solutions. HNEI is active in the deployment, operation, and performance validation of four grid-scale BESSs. The first, a 1-MW Li-ion titanate battery, was installed in 2012 at the Hawi Wind plant on the Island of Hawaii. The second is the Waiawa Battery Energy Storage Project on Oahu, with testing and evaluation of a similar battery system in a distribution line with a high penetration of photovoltaic systems.

The primary HNEI contact for this project is Richard Rocheleau. For more information concerning the project, see the Batteries for Grid Management pdf document.

A similar project, evaluating a different technology for grid management (use of hydrogen and fuel cells) is also being funded by DOE, and for details see the Grid Management Using Hydrogen and Fuel Cells for Grid Support sections of our website.
