Management matters in renewable portfolio standards

While many states have adopted renewable portfolio standards (RPS), they have employed agencies with very different missions to manage these programs. These organizational differences are important in understanding how agencies are approaching the policy implementation. However, there is little research on the comparative effectiveness of these implementation approaches. This article begins with a background of RPS programs, and presents a typology of RPS implementation agencies. The effectiveness of RPS implementation approaches is tested with a pooled state-level dataset covering 14 years of program adoption and implementation. The results indicate implementation approach is substantively important in explaining policy outcomes and the growth of renewable energy. More specifically, the findings suggest using an economic development approach is the most effective way of producing growth in renewable energy generation.
