Developers planning to construct a transmission line designed to operate at 115kV or more must submit an application for a CEC with the ACC. ARS 40-360.03. Projects for transmission projects designed to operate at less than 115kV, while exempt from the CEC requirement, must still comply with local government planning and zoning regulations. ARS 40-360.06(A)(1).
8-AZ-a.3 – Ten Year Plan
Developers planning to construct a transmission line designed to operate at 115kV or more must file a Ten Year Plan (“plan”) with the ACC on or before January 31 of each year. ARS 40-360.02(A). The developer must submit the initial plan 90 days before filing its CEC application. ARS 40-360.02(B). The plan must contain the following information to the extent that it is available:

- The purpose to be served by each proposed transmission line;
- The estimated date by which each transmission line will be in operation; and
- Technical reports, analysis or basis for projects that are included for serving customer load growth in a service territory. ARS 40-360.02(C).
If the developer fails to comply with any of these requirements, the ACC may refuse to consider the developer’s CEC application. ARS 40-360.02(E).

8-AZ-a.5 to 8-AZ-a.7 – Refer Application to the Arizona Transmission Line Siting Committee

8-AZ-a.10 to 8-AZ-a.11 – Does the TLSC Act on the Application Within the Applicable Time Period?
If the TLSC fails to act on a CEC application within the applicable time frame, the developer may, in its discretion, immediately proceed with the construction of the proposed transmission line. ARS 40-360.08(B).
8-AZ-a.12 to 8-AZ-a.14 – Does the TLSC issue the CEC?
If the TLSC issues the CEC, it will transmit the CEC to the ACC for review and approval. If the ACC approves the TLSC issuance of the CEC, the ACC will grant the CEC to the developer. If the TLSC does not issue the CEC, the developer may request that the ACC review the TLSC decision. ARS 40-360.07(A).
8-AZ-a.15 to 8-AZ-a.17 – Notice of Request for Review by the ACC
