CAISO Interconnection Queue Development Risk: Investment Committee Report

Detailed Analysis

Generated Jul 12, 2026·Dataset freshness not reported

Queue development evidence brief

Executive Summary

Development decision summary

Queue identity, documented milestones, schedule position, and development constraints.

InfraSure's current project dataset returns a count of 394 projects with status 'active' in the CAISO region as of an unknown dataset refresh date.

The 25-project preview subset is dominated by Solar+Battery hybrid projects, with individual project capacities ranging from approximately 2,071 MW to 4,357 MW; one Wind+Battery project (HOLMAN, 2,282 MW) also appears.

This is a focused evidence brief, not a complete decision report. It preserves the useful findings while making the decision-critical gaps explicit.

Queue scope

Projects in the preview span both California (CA) and Arizona (AZ) as state of interconnection, indicating the active CAISO queue includes projects sited outside California's state boundary.

Why it matters: Cross-state siting introduces permitting, land-use, and transmission path complexity that investors should factor into development risk assessments.

Queue snapshot

InfraSure's current project dataset returns a count of 394 projects with status 'active' in the CAISO region as of an unknown dataset refresh date.

Why it matters: Investors evaluating CAISO queue exposure need to know the active project universe; this count provides a directional floor but cannot be treated as exhaustive or current.

Development diligence gaps

Queue stage, milestone progression, withdrawal probability, and interconnection agreement execution status cannot be assessed for any project in this dataset.
Developer or sponsor identity is unresolved for all 25 projects in the preview result set, blocking any sponsor-quality or counterparty credit assessment.
The available records are a bounded snapshot; a complete population was not established.

claim-level citations and limits

C1directionallow confidence

InfraSure's substrate query returns a count of 394 projects with status 'active' in the CAISO region as of an unknown dataset refresh date.

No authoritative dataset refresh timestamp was reported (data_as_of is null; freshnessStatus is unknown). The count reflects InfraSure's internal corpus at an indeterminate point in time and may not match the current CAISO-published queue. The result set coverage note explicitly states overall corpus coverage is not asserted.

C2directionallow confidence

The result is explicitly bounded and paginated; these 25 rows are not a representative or exhaustive sample of all 394 active projects. Developer fields are null for all 25 preview rows, preventing ownership or sponsor-quality assessment. Dataset freshness is unknown.

C3directionallow confidence

Projects in the preview span both California (CA) and Arizona (AZ) as state of interconnection, indicating the active CAISO queue includes projects sited outside California's state boundary.

This observation is limited to the 25-row preview. The proportion of out-of-state projects across the full 394-project active queue cannot be determined from this partial result. Dataset freshness is unknown.

C4blockedblocked confidence

Queue stage, milestone progression, withdrawal probability, and interconnection agreement execution status cannot be assessed for any project in this dataset.

E4E5E6

The Interconnection Queue Progression Maturity methodology (E4) is draft-only and was not applied. Authoritative CAISO operator queue data (E5) and effective interconnection process rules (E6) are both missing from this runtime. No claim about queue maturity or development risk can be grounded without these inputs. No admissible grounding source was attached.

C5blockedblocked confidence

Developer or sponsor identity is unresolved for all 25 projects in the preview result set, blocking any sponsor-quality or counterparty credit assessment.

All developer fields returned null. No external sponsor registry or ownership data was retrieved. Sponsor quality cannot be inferred from project name or queue ID alone.

C6blockedblocked confidence

No editorial or news evidence was returned for CAISO queue development risk, leaving qualitative context about recent queue reforms, withdrawal waves, or policy changes unsupported.

The editorial evidence query returned 0 rows (E3). This may reflect query scope, dataset coverage, or a genuine absence of indexed editorial content; it does not confirm that no relevant news exists externally.

C7blockedblocked confidence

The Interconnection Queue Progression Maturity methodology matched this question on family and text criteria but remains in draft status with substrate-only grounding maturity; it was not loaded or applied and cannot validate any claim in this report.

The methodology's last review date is 2026-07-11, but this is a methodology review date, not evidence freshness. Draft status means the scoring logic, stage definitions, and evidence gates have not been validated for production use. No admissible grounding source was attached.
