Purpose of Local System Plan
Per Attachment K – Local, this LSP presentation:
• Describes projected improvements to non-PTF
that are needed to maintain reliable customer
service.
• Reflects:
– LSP Needs Assessments
– Corresponding transmission system planning studies

LSP Communication
• LSP is communicated to the PAC at an ISO-NE PAC RSP meeting once a year.
– Separate meetings can be arranged if needed
• PAC, Transmission Customers, and other Stakeholders have 30 days to provide written comments for consideration to CMP
– CMP’s contact:

LSP Communication cont.
• Each PTO is individually responsible for
publicly posting and updating the status of its
respective LSP and the transmission projects
list on a website in a format similar to the
RSP project list
• The ISO-NE RSP project list contains links to
each individual PTO’s transmission project
list
• CMP’s LSP project list is located at:
http://www.cmpco.com/SuppliersAndPartners/Transmission
Services/CMPTransmissionSvc/lsp.html

CMP LSP Project List
• Central Maine Power will update the LSP project list at least annually.
• A presentation of the LSP will be made annually.
• LSP Project List is a cumulative listing of proposed transmission solutions intended to meet identified needs.
• Similar to PTF projects in the RSP, the LSP project list contains a status of each non-PTF project:
Concept- Project is under consideration as a possible solution to a need, but little or no
analysis is available
Proposed- CMP has determined that the project is an appropriate solution to a need, but
has not yet obtained internal budget approval
Planned- Budgetary approval has been obtained
Under
Construction-
Project is approved and is under design/construction
In-Service- Project is complete

CMP’s Local System Planning
Process
• All CMP system upgrades are determined in accordance with Iberdrola USA Electric System Planning Manual.
• Planning studies can result from:
– Periodic Assessment of CMP’s 14 Local Planning Areas
– Load Growth
– Retail or Wholesale Customer Request
– Generator Interconnection Request
– System-Wide Contingency Analysis
• Studies may utilize both ISO-NE Library Base Cases and/or Local CMP Base Cases.
• Generator Interconnections on the non-PTF Transmission System are guided by the CMP Transmission & Distribution Interconnection Requirements for Generation.
