Case Studies/Discussion Group

Join APPA's Public Power Forward listserv/discussion group
This group shares developments and acts as a forum to help public power utilities prepare for a new and changing era in how you provide electricity service to your customers. It addresses issues such as grid modernization, providing enhanced services to customers, distributed energy resources, new business partnerships with vendors and other third parties, retail rate design reform, and strategic planning to accomplish these changes.

Check out case studies on community solar and other DG-related projects from public power utilities across the country, including:

Rate Design for Distributed Generation
A look at rate design options for solar and other distributed generation (DG), using public power utility case studies. The report discusses how utilities have educated customers about new rates, and how DG and non-DG customers responded. While the rate design options have some drawbacks, and might not be technically feasible for all utilities, they offer the industry new models that account for the rate impacts of distributed generation.

Solar Photovoltaic Power: Assessing the Benefits & Costs
Despite the growth, questions remain about the efficacy of solar PV as a power resource. Issues such as benefit-cost profile, the nature and magnitude of subsidies, impact on electric rates, and the degree of cost shifting among utility customers — all engender considerable debate.
