No Transmission Provider determines facilities needed with Stakeholder input Study results documented in a report and reviewed by Customer and Transmission Provider Yes TEPPC evaluates with Stakeholder input Customer Choice of Study at Customer s expense Does Transmission Provider s system meet local reliability criteria? No Transmission Provider determines facilities needed with Stakeholder input TEPPC determines high priority, performs study TEPPC determines not high priority Yes Transmission Provider coordinates with Sub- Regional Planning Group 1. Generator Interconnection Request studies are performed pursuant to the Large Generator Interconnection Procedure contained in the Transmission Provider s Open Access Transmission Tariff (OATT). Transmission Service Requests are also performed pursuant to OATT procedures. 2. All requests for economic planning studies received by the Transmission Provider are forwarded to TEPPC for inclusion in the TEPPC Master List. TEPPC will evaluate only those requests that have regional impacts. 8
