Design and Engineering services for Extra High Voltage Substation and Transmission lines for Large Data Center projects (Photo is indicative)
Large Data Center projects are very power hungry. They may need to draw a power of 1.2 Giga Watt or more from the grid to run the servers. Sometimes own power generation through conventional or unconventional mode is also necessary if grid power availability is insufficient. Satcon provides the following Engineering services for the EHV / HV / MV power system of the Data Center :
1. Feasibility study to identify the source of power supply.
2. Assistance for entering into an agreement with the local utility.
3. Providing complete consultancy and detail engineering (concept to commissioning) starting from the power drawal from the Utility substation, receiving the supply at Data center substation, appontment of contractor, stepping down the EHV voltage to a medium voltage for interconnecting with the electrical network of the Data center, complete supervision and control of the EHV substation and transmission line supply, erection, testing and commissioning.
4. Following design and drawings are delivered :
4.1. Relay and Metering SLDs of EHV switchyards, MV switchgear panels, LV switchgears and Distribution boards.
