Tracker methodology

How this project is classified

Project records describe proposed or developing infrastructure. They remain separate from the operational facility directory until reliable evidence confirms that a named facility has entered service.

Capacity and timetable information may change as a project moves through consultation, planning, construction and commissioning.
