Interconnection diligence guide
Interconnection Due Diligence Checklist for Energy Developers
Before an energy developer commits another study dollar, engineering hour, or development milestone, the decision should show what is supported, what is assumed, and what remains unknown.

The six evidence groups
Decision and alternatives
Name the project, decision owner, deadline, candidate POIs, and the pathways being compared.
Project evidence
Record market, utility territory, requested capacity, target date, site control, permitting status, and queue identifier.
Network model
Record topology source, model version, ratings, base-case injections, exact POI mapping, units, and as-of dates.
Queue evidence
Capture the source, request status, study milestone, retrieval time, coverage limits, and any unavailable fields.
Schedule and commercial assumptions
Separate supplied estimates from verified commitments. Record dependencies, exclusions, and what could change the date or cost.
Unknowns and next diligence
List the evidence that could change the comparison and assign the next question to its source owner.
A queue position is not a decision record
A queue record can be useful evidence, but it does not by itself establish deliverable capacity, a final upgrade scope, a commercial-operation date, or a management recommendation. Keep source, retrieval time, version, and coverage visible. If a required field is missing, record the gap instead of filling it with a plausible value.
GridVision AI structures authorized project and market evidence into a traceable Decision Record. Conditional deterministic screening is available only when the required authorized network evidence is present. Formal utility determinations and engineering studies remain authoritative.
How to use the checklist
- Freeze the decision date and the evidence cutoff. Do not mix later facts into an earlier recommendation without labeling the change.
- For every material claim, store the source, retrieval time, market, project identifier, and the exact field or passage supporting it.
- Keep facts, project inputs, assumptions, and unknowns in separate columns. A missing value is a diligence task, not permission to estimate.
- Score each pathway only after defining the same comparison boundary: requested MW, POI, target date, operating profile, upgrade scope, and commercial constraints.
- End with an owner and next action for every unknown that could change cost, schedule, deliverability, or the go/no-go recommendation.
Why process context matters
FERC Order No. 2023 introduced a first-ready, first-served cluster-study framework with site-control and financial requirements, study deadlines, affected-system procedures, and storage modeling provisions. The exact process still depends on the applicable transmission provider and tariff. PJM, for example, separates application and study agreements across its current platforms. Treat the governing tariff and current provider documents as the controlling source for a live project.
Authoritative starting points
Sources were checked September 2026. Process rules and queue data can change; verify the current tariff, provider portal, and study documents before relying on a project conclusion.
