Where its electricity comes from

NTT says the site uses guaranteed renewable electricity. This is a procurement statement; hourly matching and current metered consumption are not established here.

Cooling, water and backup power

NTT describes a water-cooled system with free cooling and N+1 redundancy. Site water use is not published in this profile.

Separate A and B UPS supplies with N+1 redundancy and generator backup. Generator fuel use and annual runtime are not published.

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.
