The Transmission Infrastructure Program (TIP) leverages WAPA’s statutory borrowing authority to make strategic loans to projects and often works with eligible Project Applicants to provide development assistance via Advance Funding Agreements (after the project proposal and business plan are submitted and is found to be eligible). All costs incurred and performed by WAPA are paid for by the Project Applicant.
- AES Storage Project: Proposed utility-scale 100MW battery energy storage project in Maricopa county Arizona.
- Electrical District No. 5 – Palo Verde Hub (ED5-PVH): Placed into service in 2015, this 109-mile transmission project added up to 410 MW of bidirectional capacity to the grid in solar-rich Arizona and includes 254 MW connecting to the vital Palo Verde market hub that serves consumers in Arizona, Southern California, and Nevada. The project is in active repayment status.
- Montana Alberta Tie Ltd (MATL): Energized in 2013, the MATL transmission project was developed to deliver wind energy from Montana to serve interconnected markets. The 230-kilovolt (kV) transmission project received a $162 million construction loan from TIP, which was repaid in full.
- Southline: This proposed project would build a new 240-mile, 345-kV double-circuit transmission line between the existing substations in New Mexico and Arizona, and upgrade about 120 miles of WAPA’s existing transmission lines from 115 kV to 230 kV, adding about 1,000 MW of capacity. This project is in the development phase.
- TransWest Express: Consisting of an overhead transmission line extending approximately 725 miles from south-central Wyoming crossing Colorado and Utah, this proposed project would transmit about 3,000 MW of electricity annually, generated primarily from wind resources at planned facilities in Wyoming. This project is in the development phase.
- Westlands: Westlands Transmission project is a part of the master planned Westlands Solar Park, a clean energy park. The Westlands Solar park is developing utility scale solar, energy storage and other infrastructure in western Kings and Fresno Counties to help the state of California meet its renewable energy and greenhouse reduction goals before 2030. Westlands Transmission project will help permit delivery of power from these facilities to customers in California and the western US.
