Where its electricity comes from

Google describes renewable procurement for its UK operations. A portfolio-level wind agreement is not a site-level 24-hour electricity measurement.

Cooling, water and backup power

Cooling and water-use figures have not been independently confirmed.

Backup capacity and fuel are not quantified in this profile.

Rated capacity is not present consumption. Renewable procurement claims describe contracts or certificates unless hourly matching and physical supply are evidenced. No live site meter is connected to this page.

Project location

The map distinguishes published or mapped site points from approximate location and connection areas. Dashed circles are context areas, not development boundaries. Follow the location sources for site plans.

Markers identify sites, published points or labelled connection areas. Markers are not site boundaries or entrances. EGL2’s additional outlines and route layers are explicitly identified in the developer’s map data.
