# How up-to-date is the dataset, and how are changes or cancellations handled? The dataset is continuously updated as new announcements, permit filings, imagery and utility/infrastructure data become available. Each record includes timestamps for key milestones (announcement date, construction start date, estimated activation date, etc.) and discretionary fields for cancellation/withdrawal dates where applicable. If a project is formally cancelled or withdrawn, the dataset records the withdrawal date to distinguish it from projects still in play. Because the dataset relies on public and observable sources, each record is refreshed as soon as verified information surfaces. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
