1 Key to Fields in the Project List Load Growth Interconnection Economic Reliability Concept Proposed Planned Under Construction In Cancelled N/A Backstop Too early TO Update Base case Increasing load served from the system, including new distribution substations or increasing load on existing substations. Transmission interconnection with another transmission owner. Does not include generator interconnections (which are not listed for New York). Project designed to reduce congestion, losses or other costs. Project is needed to ensure continued compliance with all NERC, NPCC, NYSRC and National Grid criteria. Also includes other reliability improvements beyond minimum criteria. Project is under consideration as possible solution to a need, but little or no analysis is available yet National Grid has internally detemined that the project is an appropriate solution to a need, but has not yet obtained SIS approval through the (if required). SIS has been approved (if required) and National Grid has management commitment to proceed with the project. Project has siting approval, as required, and is under construction. Project is complete and in commercial operation. Project has been removed from the National Grid business plan and is no longer being considered as a viable opton. Not applicable. Project is not proposed or under consideration within the Comprehensive Planning Process, and would have no impact. Project has been proposed as a regulated backstop solution for the cycle currently in progress. Project is not sufficiently advanced to warrant consideration in the, but if it proceeds it will have to be included. Project has been designated by National Grid as a Transmission Update project, will become base case in next cycle. Project is in the base case for the current Reliability Needs Assessment (RNA) for the CRP cycle currently in progress. Not required. Project is not expected to require SIS submittal and approval. Uncertain Not known yet whether the project will require SIS submittal and approval. Required Project is expected to require an approved SIS, but the process to develop the SIS has not yet begun. Scoped A scope for the SIS has been approved through the ; SIS is under development. Approved An SIS has been approved through the process.
