Guidehouse assisted Arizona Public Service with load shape development across the utility’s demand-side management portfolio
Arizona Public Service (APS) was ordered to evaluate its demand-side management (DSM) programs to focus on reducing peak energy use and demand. The utility was also required to assess each measure within its DSM portfolio that delivers highest-value peak savings while also helping to alleviate duck curve issues by shifting energy use into midday hours when solar production is highest.
Guidehouse derived 8760 hourly load shapes for every measure within APS’s DSM portfolio, including energy efficiency, demand response, load management, and energy storage measures. Guidehouse derived these load shapes using:
Guidehouse’s data supported APS in the filing of its 2018 DSM Implementation Plan and its energy storage and load management pilot. APS was able to report the planned cost-effectiveness metrics and potential customer bill savings for each of the new measures.
