SPP Wants to Defer $7B in 765-kV Projects to 2026

AI generated summary

SPP staff have proposed deferring approximately $7 billion in planned 765-kV transmission projects to 2026, while seeking approval for up to 50 projects estimated at $11.16 billion. This decision comes as part of the 2025 transmission assessment, which reflects significant load growth in the region, necessitating a comprehensive evaluation of the transmission system. SPP's vice president of engineering, Casey Cathey, emphasized the importance of refining project details to ensure the grid can handle the increasing demand effectively and efficiently.

The deferral includes critical segments of the proposed 765-kV overlay, allowing for a more strategic approach to project planning. However, staff warned that excessive deferrals could complicate future assessments and disrupt modeling efforts. With new legislation in Oklahoma potentially introducing delays in construction permits, concerns have been raised about rising costs and the feasibility of completing these essential projects. The 2025 portfolio is expected to maintain a strong benefit-to-cost ratio, supporting reliability and addressing the challenges posed by escalating energy demands.
