A comparison you can trace
A table of each agreed cost category, old and new amounts, difference, currency, basis and version date, with page citations on both sides.
Interconnection cost document comparison
What changed in your interconnection cost documents?
Compare two specified versions before your next discussion with a utility, transmission owner or project adviser. See the amounts that changed, the documented reasons and the questions that still need an answer.
Bring the facts to your next project discussion
A two-page factual explanation
What changed, the reasons stated in the documents and the questions still open for your project team, utility or adviser. Amounts with different definitions remain separately labeled.
Review and factual corrections
One 20-minute factual review and one correction round within the agreed scope. Acceptance checks source traceability, arithmetic, visible unknowns and resolution of factual issues.
The written scope identifies each file, version, date and page range. Complete versions must be available to identify references outside those pages. Extra pages, documents or new versions require an agreed written scope change before additional work begins.
This historical Bradford AE2-139 example compares selected cost amounts and milestone dates in independently retrieved 2024 and 2025 public PJM filings. It includes source-page citations, arithmetic checks and open questions. It is a public-data demonstration, not customer work or engineering validation.
The sample covers selected source pages. Historical amounts and dates do not establish the project's current status, unpaid balance or fulfillment of milestones.

Start with the decision you need to prepare for
Send a short project note
Tell us the project or queue ID, the change you want to understand, your decision deadline and who owns the budget. Qualification starts by email; an initial meeting or file upload is not required.
Agree the files, fee and date
If the scope fits, we inspect the actual documents and confirm permission to use them. Your written quote names the versions and pages, deliverables, responsible person, fixed fee, feasible delivery date and acceptance process.
Review the cited comparison
Work starts after scope acceptance, authorized evidence readiness and the agreed initial payment. Your team checks the cited rows and explanation, and factual corrections are tracked to resolution.
Proposed payment terms are 50% after acceptance of the written scope and before work starts, with the balance on acceptance of the agreed deliverables. Payment is requested after the exact fee, authorized inputs, responsible person and feasible delivery date are agreed.
Email-first qualification
Tell us about one project
Share your project or queue ID, the change to investigate, the next relevant date and your budget owner. We will reply by email with the next scope questions. You can begin with a short description and provide authorized documents once the scope is useful.
Public links or readable PDF versions are suitable. Redacted documents are acceptable when the agreed comparison remains possible. Keep confidential files out of this initial form.
Factual document review
This service organizes and checks the facts in the specified pages and categories. It does not establish the complete project budget or current unpaid balance. Engineering analysis, independent engineering validation, new cost forecasts, upgrade-necessity assessments, legal interpretation and investment or payment recommendations require separately agreed qualified work.
