Strategen & Southwest Energy Efficiency Project (SWEEP)
This technical research report is provided by Strategen Consulting on behalf of the Southwest Energy Efficiency Project (SWEEP). To examine the potential impact of the Energy Rules on Arizona’s electricity system and its impact on electricity customers, Strategen’s analytical approach and resulting recommendations were informed by two main research questions: 1) Would the implementation of the Commission’s Energy Rules cause the utilities to deviate from a least-cost resource portfolio, thereby increasing costs for Arizona electricity customers relative to business as usual? And, 2) Would the implementation of the Commission’s Energy Rules cause the utilities to compromise their primary resource planning objectives of affordability, reliability, risk mitigation, and environmental performance?
