Grid Modernization (GM)

The utility grid needs to be modernized to allow more integration of variable and intermittent energy from renewable energy resources, enable two-way power flow to fully leverage customer distributed energy resources, and help Hawaii meet its renewable energy goals.

Initiatives

GM-01

Modernize the grid to allow more flexibility and integration of renewable energy resources and mitigate potential integration constraints (voltage, thermal, protection).

GM-02

Increase visibility, grid functionality, and control of the grid to increase reliability, enable interoperability of distributed energy resources, and increase resiliency.

GM-03

Enable two-way communication network, data exchange, and interoperability throughout the utility and edge of the grid (for renewable distributed energy resources) with new intelligent power equipment and systems.

GM-04

Mitigate impacts on heavily-penetrated circuits to maintain proper system voltages by deploying grid-connected voltage management at the transmission, distribution, and secondary circuits.

GM-05

Optimize the utilization of existing equipment and assets to maximize remaining life and control costs.

GM-06

Design and implement microgrid applications with effective electric power system sectionalization and systematic reconfigurations. (A microgrid is a group of interconnected loads and distributed energy resources within clearly defined electrical boundaries that acts as a single controllable entity with respect to the utility's electrical grid and can connect to a public utility's electrical grid to operate in grid-connected mode and can disconnect from the grid to operate in island mode, and that is subject to a microgrid services tariff and generates or produces energy.)
