Notice to all NERC Planning Coordinators and Transmission Planners: re PCTP Sharing and Non-Disclosure Agreement.

Since the formation of EIPC in 2009, members have been signatories to a common Sharing and Non-Disclosure agreement to facilitate exchange of Critical Energy Infrastructure Information (CEII) for EIPC studies.

Following that example, a similar Planning Coordinator and Transmission Planner Non-Disclosure Agreement (PCTP NDA) has been developed for use by all NERC Planning Coordinators and Transmission Planners, to facilitate sharing of CEII in support of compliance with FERC Order 1000 and NERC MOD-032. For convenience this NDA is posted here and information on communicating with the PCTP Tracking Coordinator is posted under the Contact tab of this web site.

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 builds upon, rather than replaces, 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 may 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 majority of the Eastern Interconnection.

The EIPC provides 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 provides coordinated interregional analysis for the entire Easter 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 for a project involving interested stakeholders in the development of policy futures for transmission analysis.(Learn more about the DOE-funded project.)

The Stakeholder Steering Committee (SSC) is a body of stakeholder representatives that is convened at appropriate times to inform and provide input on the EIPC's efforts.(Learn more about the SSC.)
