Executive Evidence Summary
A narrow forecast margin made remaining startup work a material decision issue.
The commission testimony records Unit 3 schedule margin and remaining testing at a specific point in time. This public-record retrospective shows how that warning could be presented with cost and oversight decisions across Units 3 and 4; CFIG did not work on the project.
Public Georgia Public Service Commission monitoring testimony, prudence filings and docket records, the Nuclear Regulatory Commission Unit 4 status, and Georgia Power operation notices.
The 27th monitoring testimony identified a narrow Unit 3 risk-adjusted schedule margin while startup testing remained. CFIG retrospectively connects that contemporaneous risk to cost, prudence, and responsibility decisions.
A small margin can alter completion forecasts, prolong work, and change the evidence needed for owner, commission, and ratepayer decisions. Later operating outcomes cannot be treated as knowledge available at the earlier gate.
When the Unit 3 forecast margin was about four weeks and material testing remained, before the next lawful completion, cost, or prudence decision.
A startup gate dashboard, cost and prudence ledger, and continue/restructure/stop decision book could show supported facts, open issues, responsible users, and lawful options.
Forecast changes and cost responsibility could become harder to trace. The report does not perform engineering review, decide nuclear safety, or assert that CFIG would have changed commercial-operation dates.
Executive significance: A bounded evidence record could help authorized decision-makers assess completion forecasts, cost responsibility, and public oversight without claiming a different historical result.
Documented Path
What the portfolio’s public record shows
Recorded project path
Public need and authorization → Design and procurement → Construction → Test and startup → Risk-adjusted completion → Prudence and cost recovery → Commercial operation.
Evidence boundary
This is a high-level public-record demonstration. It excludes nonpublic plant data, protected security information, safeguards information, detailed layouts, operating vulnerabilities, and independent nuclear engineering or safety judgments.
Retrospective CFIG Analysis
What CFIG would bring into one decision picture
Condition CFIG connects
CFIG connected reduced schedule margin, remaining testing, likely startup discoveries, cost growth, public prudence review, responsibility, and the later commercial-operation outcome.
CFIG-informed path
Source gate → Condition connected → Risk-Adjusted Completion and Startup Gate Dashboard → Cost Growth, Responsibility, and Prudence Traceability Ledger → Continue, Restructure, or Stop Decision Book → Should the current completion path continue, be restructured, receive added controls, be deferred, or stop at the next lawful gate? → Gives executives and regulators one bounded record for completion risk, cost responsibility, and public decisions.
Decision to be supported: Should the current completion path continue, be restructured, receive added controls, be deferred, or stop at the next lawful gate?
Decision Window
When meaningful options were still available
When risk-adjusted schedule margin fell to about four weeks while significant testing and startup work remained.
Why timing mattersA small margin meant one startup or test problem could move the working completion plan.
Comparative Differential Analysis
Documented path versus CFIG-informed path
Historical facts and retrospective analysis are separated below. The CFIG column describes what the demonstration indicates CFIG would have surfaced; it does not claim certainty or prior involvement.
| Dimension | Documented project record | CFIG-informed presentation | Differential | Likely impact or benefit |
|---|---|---|---|---|
| Schedule and tests | The 27th monitoring testimony stated that Unit 3 risk-adjusted schedule margin was narrow while startup testing remained. | A high-level startup dashboard could show forecast, remaining activities, uncertainty, and the next owner decision gate. | A single view could distinguish a forecast from completed and verified work. | Potentially earlier escalation of schedule risk, without establishing that completion could have happened sooner. |
| Cost and prudence | Public commission filings separately address construction costs, responsibility, prudence, and recovery terms. | A ledger could connect each reviewed cost position to its public source, responsible party, status, and commission question. | Cost information could be reconciled with the completion timeline for oversight. | Potentially clearer ratepayer and owner decisions; this analysis does not calculate recoverable cost. |
| Decision responsibility | The owner, monitors, commission, regulator, and qualified nuclear professionals held different roles. | A decision book could list the lawful options and evidence each authority would need at a gate. | An executive recommendation could remain separate from regulatory or professional approval. | Potentially better accountability without replacing the Nuclear Regulatory Commission, state commission, or licensee. |
| Later milestones | Later official material records commercial operation and Unit 4 status after the earlier margin warning. | A retrospective timeline could mark what was known when, then compare it with the later record. | Later success or delay would not be used to erase an earlier risk signal. | Potentially stronger learning and public explanation, without hindsight presented as a contemporaneous forecast. |
Potential Impact
Why the differential matters
Time effect
Documented path: The contemporaneous monitoring testimony showed a small Unit 3 schedule margin while startup testing remained. CFIG-informed difference: A dashboard could show forecast margin and open tests at each decision gate without displaying protected plant details. Practical significance: A decision-maker could see how a small remaining margin affects the credibility of a forecast. No earlier completion is claimed.
Cost effect
Documented path: Commission filings document cost and prudence questions; this companion does not independently quantify a causal cost from one testing issue. CFIG-informed difference: A source-linked ledger could distinguish supported, disputed, pending, and allocated positions for authorized review. Practical significance: Clearer separation of cost evidence and proposed responsibility could help public oversight without inventing savings or recoverability.
Responsibility effect
Documented path: The owner, commission, independent monitors, Nuclear Regulatory Commission, and nuclear professionals had distinct responsibilities. CFIG-informed difference: A decision book could show who may request more evidence, approve a lawful option, or make a licensed safety judgment. Practical significance: A high-level CFIG view could improve handoffs while leaving technical and regulatory authority with those legally responsible.
Public decision benefit
Documented path: The project ultimately has later public operation records; those events do not resolve what was knowable at the earlier risk window. CFIG-informed difference: An evidence timeline could preserve contemporaneous assumptions alongside later outcomes and prudence findings. Practical significance: That distinction could improve explanation and future governance, without a claim that CFIG would have prevented delay or loss.
Tangible Options
Three outcome-level choices—not a self-execution manual

Completion Boundary
What this report does—and does not claim
Claims control: This companion does not state that CFIG would certainly have prevented delay, loss, failure, dispute, or another historical outcome. It demonstrates how CFIG could have organized the available record into earlier visibility, a clearer decision window, outcome-level options, and a more accountable executive choice.
Professional boundary
CFIG supports decision-makers. Licensed and authorized professionals retain responsibility for engineering, safety, legal, environmental, accounting, regulatory, and other protected judgments.
