For EPC contractors before Taking-Over, and owners after it
EPC contractors buy plant communications as part of the substation and buildings scope. The systems have to be installed, tested and documented before the owner takes over the plant. On Suez Wind Energy, we are delivering IP telephony and video conferencing for PowerChina at the north and south substations.
Owners take over the systems at handover and run them for the life of the plant. They also contract us directly for their buildings and sites. ENGIE did so for the relocation of its Egypt headquarters and for outdoor wireless on the ENGIE Solar plant at Nadec City in Saudi Arabia.

Ready for Taking-Over, then run for the owner
Before Taking-Over, we commission the systems with the EPC contractor so the owner’s team takes over equipment that works.
After Taking-Over, the owner can contract us to run the systems under a service level agreement (SLA). We have run the network at Red Sea Wind Energy’s 220 kV substation under SLA since 2021.
Frequently asked questions
How is Plant Communications different from Site Mobilization?
Site Mobilization connects the temporary site facilities (TSF) used during construction. Plant Communications is the permanent equipment at the substation and plant buildings, handed over to the owner at Taking-Over.
Can you provide mobile coverage at a remote site?
Yes. At Suez Wind Energy’s Ras Ghareb (north) site, we deployed NTRA-licensed 2G, 3G and 4G LTE coverage for 1,000 concurrent users. We powered it with a solar-diesel hybrid system and connected it through microwave backhaul.
Can you work to the EPC contractor’s specification?
Yes. PowerChina contracted us for turnkey delivery on three wind farms, and we delivered to its specification.
Who runs the systems after Taking-Over?
The owner’s team, or us under a service level agreement. We run the network at Red Sea Wind Energy’s 220 kV substation under SLA.
Do you support the supervisory control and data acquisition (SCADA) system?
We provide the ICT services the SCADA system depends on: networks, connectivity, access and IT support.
