Arlington Valley is a 600 MW natural gas facility located on approximately 3,000 acres of land about 50 miles southwest of Phoenix, Arizona. The facility sells capacity and electricity to an investment grade load serving utility under a tolling agreement that was extended through October 2031. In 2019, a heat rate call option agreement (HRCO) was entered into with an investment grade counterparty to cover the non-summer months through 2025. The Arlington Valley facility is adjacent to the Palo Verde hub, allowing for additional capacity and energy to be sold into the Desert Southwest (DSW), or the California Independent System Operator (CAISO) wholesale markets when not called upon to support the HRCO.
Quick Facts
- Utilizes General Electric 7FA combustion turbines, deployed through two Aalborg (CMI) heat recovery steam generators (HRSGs) with duct burners, and a single GE D11 steam turbine
- Supplied by two large natural gas pipelines (El Paso and Transwestern), allowing a dual fuel connection where each of two pipelines can provide 100% of the facility’s fuel requirements
Proposed Arlington Valley Uprate Project
Arlington Valley, LLC, a subsidiary of Capital Power US Holdings Inc.. (“Capital Power”) has applied for an amendment of its Certificate of Environmental Compatibility for the Arlington Valley Energy Facility to authorize the completion of a proposed uprate project that will increase the nominal generating capacity of the facility from 580 MW as currently permitted to approximately 625 MW. The uprate project consists of upgrades and replacements of existing natural gas-fired turbine components and software upgrades to increase the efficiency of the turbines’ operations. No physical earthworks are required outside of the existing facility footprint.
The Arizona Corporation Commission reviewed the amendment application at an open meeting on December 3, 2024, and unanimously approved Capital Power’s request to permit the Arlington Valley Facility to operate at 625 MW.
