Oahu Grid Analysis

Under this project, the Hawaii Natural Energy Institute (HNEI) performed an analysis of the Oahu electricity grid under funding from the US Department of Energy and the Hawaiian Electric Company (HECO).  The study was aimed at an assessment of the technical and economic impact of current and future use of renewable energy sources on the island of Oahu, in the HECO grid.  This is an example project that has already been completed.  It is similar to other projects conducted for the electricity grids on Maui and the Big Island.

Project objectives included the assessment indicated above, developing a model of the existing HECO grid, examining scenarios for future possible expansion of renewables, and suggesting system modifications to yield successful integration of additional renewable resources.  To see a report on validation of the grid models developed, click here.  Details of the overall project can be seen on the Oahu Grid Analysis Project pdf document.

HNEI accomplishments in the grid analysis projects led to studies exploring different approaches to dealing with potential problems of increased renewable energy use.  These efforts are presented in the Grid Storage Systems and Smart Grids sections of our website.
