TCPC Meeting Policies
FERC Standards of Conduct
The FERC Standards of Conduct state that Transmission Function Employees are prohibited
from disclosing non-public Transmission Information unless they disclose it on the OASIS. Also,
Transmission Function Employees and Shared Employees are expressly prohibited from
disclosing non-public information to Energy or Marketing Affiliates.
Anti-Trust Policy
It is the committee’s policy to comply with all state and federal anti-trust laws. One objective of
the TCPC is top promote or enhance competition. Careful attention should be paid to any
discussions regarding you or your competitors prices, allocation of markets, customers, or
products, limiting production, and excluding dealings with other companies.
Confidentiality
Certain information may be protected as confidential due to Standards of Conduct concerns or
because it is classified as Critical Energy Infrastructure Information. Otherwise, it should be on
the OASIS. Committee members agree not to share committee activities with the press and do
not discuss ideas or concerns other than your own in a public forum.

TCPC Objectives
• Plan the expansion of the transmission system to
ensure reliable, efficient delivery of energy to
customers at a reasonable cost.
• Develop and coordinate plans with interested
stakeholders at the local, state, and regional level to
identify and address concerns in the early stages of
project development.
• Ensure openness and transparency while
addressing applicable regulatory requirements.

What is Transmission Planning?
The process of evaluating the transmission system to
identify transmission facilities required to deliver existing
and future generating resources to existing and future
customer loads while balancing reliability, societal
impact and cost.

Types of Planning Studies
• System Interconnection Requests
o Generator, Load or Transmission Interconnection
• Feasibility Study
• System Impact Study
• Facilities Study
• Transmission Service Study
• Reliability Study
• Economic Study

Transmission Planning Process
Major factors in the process:
•
•
•
•
•
•
•
Future planning periods (5, 10, 20+ years)
Load forecasts (existing + future growth scenarios)
Generation output (serve local load vs. off-system sales)
Generation types (thermal, hydro, wind, solar, etc.)
Planned projects (local and regional)
System disturbances (consider all relevant outages)
Reliability criteria (the measuring stick for adequate
transmission system performance)
• Transmission system commitments (capacity availability)
• Local, state, and federal regulatory requirements
