According to a recent LinkedIn post from Nira Energy, internal analysis of the Southwest Power Pool (SPP) interconnection queue suggests that only one in five projects advance to a Generator Interconnection Agreement. The post attributes this outcome not to procedural flaws but to how project economics and system upgrade requirements play out over time.

The company’s LinkedIn post highlights work by a Nira Energy transmission planning engineer who reviewed three years of SPP DISIS study results across seven study phases. According to the post, roughly $83 billion in network upgrades have been identified, with estimated costs peaking at Phase 1 and then falling as projects withdraw from the queue.
The post notes that this pattern of early high upgrade costs followed by attrition has repeated twice in prior queue cycles, yet suggests that the 2024 queue could diverge from historical behavior. If the new queue cycle sustains more projects through later phases, it could signal shifting economics or policy drivers for transmission and generation development in the SPP region.
For investors, the analysis points to significant underlying transmission investment needs that may influence capital allocation toward grid infrastructure, engineering services, and related consulting. The reference to a subscription product, ISO Insights, also indicates that Nira Energy may be seeking to monetize its analytical capabilities, potentially adding a recurring revenue stream tied to data and market intelligence.
