Demand Response Potential Study

Navigant developed a state-of-the-art model to help Hawaiian Electric Companies understand its demand response potential

Challenge

With growing amounts of intermittent renewables that needed to be integrated into the grid, the Hawaiian Electric Companies (HECO, HELCO, and MECO) engaged Navigant to assess demand response (DR) potential across its territories.

Solution

Navigant developed a highly granular bottom-up modeling approach based on hourly load profiles for different market segments and end-use loads (including electric vehicles and batteries) for all five islands served by the three companies. The team developed a methodology to assess DR potential based on the hourly load profiles and flexibility of end-use loads to provide traditional and advanced grid services that include fast and flexible response (e.g., fast frequency response, regulation, spin, and non-spin). Throughout the engagement, Navigant worked closely with various stakeholder groups and with the Hawaii Public Utilities Commission (PUC) to present the study’s findings.

Impact

Navigant’s state-of-the-art model produced the potential results that fed into the Hawaiian Electric Companies’ Power Supply Integration Plan (PSIP) and were successfully integrated within the PSIP. The Hawaii PUC recently approved a portfolio of DR programs based off the results of this study.
