2026 Transmission Economic Assessment Methodology (TEAM) Update

The Transmission Economic Assessment Methodology (TEAM) is CAISO’s framework for evaluating the economic benefits of transmission investments and upgrades. TEAM provides a consistent approach for assessing project costs, benefits, uncertainties, and alternatives to support informed transmission planning decisions that improve grid efficiency, reliability, and value for ratepayers. The California ISO will review and update the TEAM methodology through a stakeholder process as needed to reflect evolving market conditions, transmission planning practices, regulatory requirements, and enhancements to modeling and analytical tools.
