MAINE –On January 4, the PUC issued an order in Docket No. 2009-219 (readers can look up the docket in the MPUC website) adopting statewide interconnection procedures. These procedures apply to all technologies, regardless of system size. The procedures establish four levels of review for interconnection requests and utility external disconnect switches are prohibited for small, inverter-based systems. A number of provisions in the standard were based on IREC’s Model Interconnection Procedures, including screens for network interconnections, insurance levels, and timelines. Although this policy was not adopted in time for inclusion in the 2009 Freeing the Grid Report, it would have received an “A” and surpassed Virginia as the top score for Interconnection. Sorry Virginia.
