π Project Overview
Dogger Bank A is Phase 1 of what will be the world's largest offshore wind farm at 3,600 MW across three phases. Using 13 MW GE Haliade-X turbines β the world's most powerful at time of selection β each turbine is taller than the Eiffel Tower at 260m to blade tip. It is the UK's first large offshore wind farm to use HVDC export cables, a technology necessity at 130km from shore.

π Project Timeline
πΏ Environmental & Planning
The Dogger Bank itself is a Natura 2000 site (Dogger Bank SAC). The project sites are adjacent to but outside the SAC boundary. Sand wave habitats were surveyed in detail. Scour protection creates diverse reef habitat. The project is monitoring sandeel β a key food source for seabirds β throughout operation.
