Transmission Studies

ISO-NE planning studies

ISO-NE Transmission Planning conducts studies to support the Regional System Plan and handles requests to change interconnection and transmission service. ISO-NE ensures transmission owners comply with requirements regarding changes to capacity or facilities. Generator and transmission interconnection inquiries are referred to ISO-NE, and the ISO-NE interconnection process is followed. ISO-NE’s Transmission, Markets, & Services Tariff, Section II provides a summary of the ISO-NE interconnection process and explains procedures electric energy suppliers must follow to access the region’s transmission system to transport electricity throughout New England. Entities requesting interconnection of a generating facility (including increases to the capacity of an existing generating unit or decommissioning of a generating unit) or requesting interconnection of a merchant transmission facility within the ISO-NE RTO must do so within ISO-NE's defined interconnection process. Impacts to the system are determined by a series of studies which may include a Feasibility Study, System Impact Study, and Interconnection Facilities Study.
