START THE CONVERSATION

A useful starting point.

These inputs help us understand the scope. If your project is at an earlier stage, tell us what you have available.

  • Voltage level, capacity, and approved system requirements
  • Site layouts and geotechnical information where applicable
  • Equipment data and project specifications

PLANNING YOUR ENGINEERING SCOPE

Questions before
the design begins.

What substation voltage levels does ETTS support?

ETTS provides basic and detailed engineering for substations up to 400 kV. The project voltage, arrangement, equipment and applicable specifications determine the engineering scope.

Can electrical and civil design be included in one scope?

Yes. Agreed packages can cover electrical layouts, earthing and lightning protection, equipment sizing and cable routing alongside supports, gantries, foundations, trenches and related civil works. Equipment and vendor information are coordinated across the disciplines.

Are power-system studies and vendor reviews available?

ETTS capabilities include power-system studies using ETAP, vendor drawing review and OEM specifications. Tell us the network information and study or review requirements so that the required inputs and deliverables can be established.
