While advancements in solar technology have significantly lowered hardware costs, solar "soft" costs such as permit and interconnection application processing and customer acquisition and installation labor remain stubbornly high and pose barriers to wide scale photovoltaic (PV) deployment.

Building off 2012 and 2013 National Renewable Energy Laboratory (NREL) research that identifies interconnection as a primary time and cost savings opportunity, NREL, with support from the Solar Electric Power Association, the Electric Power Research Institute, and Western Area Power Authority, has organized and is facilitating the Distributed Generation Interconnection Collaborative (DGIC)–a collaborative community of utilities and other stakeholders focused on innovative approaches to distributed generation interconnection that address concerns of time, costs, grid safety, and reliability.

Through the DGIC's efforts, data for more than 20,000 residential and commercial PV systems has been collected to identify areas for process efficiency improvements related to application review and approval, interconnection agreement processing, and permission to operate paperwork. In addition, the DGIC holds monthly informational webinars, with topics chosen by the group’s more than 100 members.
