Innovation

Energy Storage (ES)

Use chemical, mechanical or thermal processes to capture electricity or heat for use later or to manage short-duration events that support the utility grid.

Initiatives

ES-01

Install energy storage capable of storing excess energy that is properly controlled and coordinated with the utility and allows integration of more distributed energy resources.


ES-02

Install energy storage that provides grid services to Hawaiian Electric, such as operating reserves, ramp smoothing, frequency control, and voltage control.


ES-03

Develop and install smart and adaptable energy storage technologies with, but not limited to, the following characteristics:

  • Flexible grid-connected and/or stand-alone
  • Integrated with intelligent machine-learning algorithms for control and operation
  • Multiple monitoring, control, and protection attributes
  • Provides multiple ancillary services in grid-connected and islanded modes
  • Able to respond during both transient and steady state conditions.
