Proposal Alert Spotlight
APS Issues 2025 All-Source Request for Proposals (RFP)
Arizona Public Service (APS) has opened the doors to one of the Southwest's most significant energy procurement opportunities with their 2025 All-Source RFP, seeking at least 1,000 MW of new generation capacity. This comprehensive solicitation stands out not only for its substantial scale but also for its inclusive approach to diverse energy technologies and meaningful partnerships with tribal communities. With a generous timeline extending to February 2026 for submissions and commercial operation dates spanning 2029-2031, this RFP provides energy developers with ample runway to craft competitive proposals.
What makes this opportunity particularly compelling is its dual focus on meeting Arizona's growing energy demands while creating specific pathways for development within Navajo Nation and Hopi Tribe territories. APS is casting a wide net for technology solutions, accepting everything from traditional solar and wind projects to cutting-edge energy storage, geothermal, biomass, and even nuclear proposals with a minimum 5 MW threshold. The utility's emphasis on resources that can handle summer peak demands, overnight energy needs, and extra high load factor customers reflects Arizona's unique energy challenges in an increasingly electrified economy.
Energy developers, engineering firms, project financiers, and renewable energy companies across the technology spectrum should take serious note of this RFP. The multiple contract structures available—including Power Purchase Agreements, Build Transfer Agreements, and EPC arrangements—offer flexibility for various business models and risk profiles. Additionally, the specific opportunity for thermal generation at APS's existing Desert Sun Power Plant site could attract developers interested in repowering or expanding existing infrastructure. With coverage spanning 11 of Arizona's 15 counties, this RFP represents a rare chance to participate in shaping the state's energy future while contributing to economic development in tribal communities.
