5. There are certain factors, or “conditions precedent,” that
are required for continued transmission build-out
Robust business case for plan
Regional tariff that matches who benefits with who pays over time
Increased regional energy policy consensus
Cost recovery mechanisms that reduce financial risk

6. meets reliability needs, policy needs, and economic needs
The continued execution of our planning process according to it’s guiding principles will ensure a grid that supports the future fleet
Develop a transmission plan that meets all applicable NERC and Transmission Owner planning criteria and safeguards local and regional reliability through identification of transmission projects to
meet those needs
Make the benefits of an economically efficient electricity market available to customers by identifying transmission projects which provide access to electricity at the lowest total electric system cost expansion plan that meets reliability needs, policy needs, and economic needs
Fundamental Goal
The development of a comprehensive expansion plan that
meets reliability needs, policy needs, and economic needs
Analyze system scenarios and
Provide an appropriate cost allocation mechanism that ensures that costs of transmission projects are allocated in a manner roughly commensurate with the projected benefits of those projects
make the results available to state and federal energy policy makers and other stakeholders to provide context to inform
regarding choices
Coordinate planning processes with neighbors and work to eliminate barriers to reliable and efficient operations
Support state and federal energy policy requirements by planning for access to a changing resource mix
