The Hawai‘i Natural Energy Institute (HNEI) is leading a team engaged in the research, development, deployment, and analysis of grid-scale battery energy storage systems (BESS) that are designed for system control and power quality support at the generation, transmission, and distribution levels. The project aims to:

  • Identify high value BESS applications at various system levels;
  • Develop control algorithms that maximize the benefit to the grid/customer and the lifetime of the BESS;
  • Evaluate and optimize those algorithms under real world operating conditions.


The Office of Naval Research (ONR) is funding HNEI to identify technologies that have the potential mitigate the adverse impacts of integrating intermittent renewable energy resources onto the electricity grid. HNEI selected Altair Nanotechnologies Inc (Altairnano) to manufacture three BESS units and collaborated with Altairnano and Integrated Dynamics Inc. to develop control algorithms for wind smoothing, frequency response, voltage (VAR) support, and power smoothing for the various deployment strategies of the three BESS units.
