We recently published a report, co-funded with the California ISO: Distributed Energy Resource Integration: Summarizing the Challenges and Barriers.
The California Independent System Operator (ISO) engaged Olivine, Inc. to provide a summary report of the challenges and barriers that exist for distributed energy resources (DERs) to provide grid services. These resources, located on the distribution system, include energy storage, plug-in electric vehicle (PEV) applications, demand response and combinations thereof that include photovoltaic solar or other distributed generation resources. With a growing list of new technologies, business models and changing regulations that include 12 active CPUC proceedings, the DER landscape is increasingly complex. This report addresses DERs that generate electricity and require interconnection to the ISO as well as those that alter consumption (such as demand response) and do not require interconnection. This report does not delve into the question of whether or not wholesale integration is appropriate or the best application of DERs to meet California’s electricity needs.
