Welcome to the EIPC website

The Eastern Interconnection Planning Collaborative (EIPC) represents a first-of-its-kind effort to involve Planning Authorities in the Eastern Interconnection to model the impact on the grid of various policy options determined to be of interest by state, provincial and federal policy makers and other stakeholders. This work will build upon, rather than replace, the current local and regional transmission planning processes developed by the Planning Authorities and associated regional stakeholder groups within the entire Eastern Interconnection. Those processes will be informed by the EIPC analysis efforts including the interconnection-wide review of the existing regional plans and development of transmission options associated with the various policy options.

The EIPC was initiated by a coalition of regional Planning Authorities (see list below).. These Planning Authorities are entities listed on the NERC compliance registry as Planning Authorities and represent the entire Eastern Interconnection. 

The EIPC will provide a grass-roots approach which builds upon the regional expansion plans developed each year by regional stakeholders in collaboration with their respective NERC Planning Authorities. This approach will provide coordinated interregional analysis for the entire Eastern Interconnection guided by the consensus input of an open and transparent stakeholder process.  

The EIPC received funding from the U.S. Department of Energy in 2010 to initiate a broad-based, transparent collaborative process to involve interested stakeholders in the development of policy futures for transmission analysis. Learn more about the DOE-funded project.
The Stakeholder Steering Committee (SSC) is the body of stakeholder representatives that works collaboratively to inform and provide input on the EIPC's efforts. Learn more about the SSC.
