Integrated Grid Planning

Integrated Grid Planning Symposium

November 15-16, 2017

The Hawaiian Electric Companies developed a Grid Modernization Strategy, which was filed with the Hawaii Public Utilities Commission (PUC) on August 29, 2017. As part of the Grid Modernization Strategy, the Companies proposed a new Integrated Grid Planning process that integrates the needs at all levels of the system: customer, bulk power resources, transmission, and distribution. The comprehensive, customer-focused, and cooperative grid planning process would engage customers and stakeholders at key junctures in the integrated resource, transmission, and distribution planning effort.

Through Order No. 34696 accepting the Hawaiian Electric Companies' Power Supply Improvement Plans, the PUC directed the Hawaiian Electric Companies to file with the commission "a report that details the Companies' planning approach and schedule for the next round of integrated planning. The Companies shall file this report with the Commission no later than March 1, 2018."

A grid planning Symposium focusing on leading practices and related planning technologies and tools across the U.S. was held as part of this effort to develop a new integrated grid planning process for Hawaii. You can view our Integrated Grid Planning webpage for the latest information.

Welcome: On November 15 & 16, 2017, the Hawaiian Electric Companies held an Integrated Grid Planning Symposium. The Symposium was attended by roughly 150 stakeholders in person and by another roughly 80 via webinar on Day 1 and 50 on Day 2. Copies of panelist presentations can be found on this web page, and recordings of the webinar will be available shortly.


This symposium will discuss the state of the art for Integrated Grid Planning (IGP) across the U.S. Also, inform attendees of the processes, methods, and technology being used and lessons learned. Hawaiian Electric is pleased to host this symposium with support from the US Department of Energy.
