Case Study: Arizona Public Service achieves streamlined program delivery and major cost reductions with Uplight

APS Home Performance with ENERGY STAR

Arizona Public Service (APS), Arizona’s largest investor-owned electric utility serving over 1.1 million customers, ran a successful Home Performance with ENERGY STAR (HPwES) program but faced rising trade‑ally and customer expectations, tougher cost‑effectiveness tests, and limited access to program data. To scale and streamline delivery, APS sought a modern, standards‑based software solution and selected Uplight’s Workflow Automation and Energy Assessment platform to improve transparency, reduce administrative burden, and enable HPXML data exchange.

Uplight implemented its Workflow Automation and Energy Assessment tools to give APS direct access to program and project workflows, automate approvals, and improve contractor coordination. The Uplight platform cut implementer administrative time/cost by 50%, contractor admin time to submit projects by 31%, and APS data‑processing time by 66%, while tripling trade‑ally satisfaction and enabling better customer segmentation and cross‑promotion.
