PSIP Resource Plan: December 2016
The Hawaiian Electric Companies are at the forefront of integrating renewable resources onto their electric power grids. By statute, they must achieve a 100% Renewable Portfolio Standards (RPS) by 2045. We have been honored to work with them on a series of resource plans for attaining that goal.
The Power Supply Improvement Plan—a resource plan ordered and named by the Hawai‘i Public Utilities Commission— for December 2016 continued the analysis started and reported on in the April 2016 PSIP. Unlike past resource plans, only one PSIP was published under the Companies’ One Company initiative. The December 2016 PSIP aggressively pursued integrating renewable energy into the generation mix, explaining how 100% RPS could be attained by 2030.
The PSIP team consisted of Company resource planners and several consultants including E3, Ascend Analytics, HD Baker & Company, and Solari. To create this plan, the PSIP team used three different modeling tools—RESOLVE, PowerSimm Planner, and PLEXOS— to develop, compare, and contrast a number of different resource mixes based on the same set of input assumptions. The planning process also included about two dozen intervenors admitted to the docket by the Public Utilities Commission.
The utility's resource planners first filed a PSIP Revised Work Plan, then over subsequent three months, assimilated all this information into the resultant December 2016 PSIP report and appendices.
