Remote terminal unit (RTU) turnkey replacement services

Sample RTU replacement project flow:

1.      Site walk and define the project scope with all appropriate utility teams

a.      Compare existing substation drawings against field equipment and on-site drawings

b.      Take site measurements to ascertain space availability

2.      Provide a detailed project scope document and proposal including:

a.      outage schedule

b.      equipment bill of material

c.      design requirements

d.      installation and commissioning

3.      Work closely with key utility stakeholders to ensure approval of drawings per customer codes and standards
