Onshore wind farms sit, almost by definition, in some of the most exposed and least-connected places in the country — upland moor, remote coastline, the end of a very long track. Yet everything that keeps them running efficiently depends on a data link that holds: turbine SCADA, condition monitoring, metering, and the CCTV that protects the asset. Here's what dependable wind-site connectivity involves.
What actually needs to get on and off site
- SCADA & control — real-time status, performance and alarms from each turbine back to the control room.
- Condition monitoring — vibration and drivetrain data that flags a failing component before it fails.
- CCTV & security — protecting substations, compounds and high-value plant in the middle of nowhere.
- Remote engineering access — so a specialist can log in rather than drive three hours to reset something.
Lose the link and you lose visibility of all of it at once — generation data goes dark, faults go unseen, and someone ends up on the road.
The connectivity challenge
There's rarely fibre, mobile coverage is patchy, and links that do exist often sit behind CGNAT, breaking remote access. The environment is harsh, power can be intermittent, and turbine OT must be kept properly separated from CCTV and corporate traffic for both safety and security.
What good looks like
- Multi-bearer connectivity — satellite where there's no fibre, with 4G/5G failover, so a single outage doesn't blind the site.
- A fixed public IP so SCADA, VPN and remote access stay reachable — and survive a failover event.
- Proper network segmentation keeping turbine OT isolated from cameras and office traffic.
- Power & UPS-backed comms so the link rides through grid dips and outages — see Power & UPS.
- Integration into head-office systems — getting OEM data (GE, Vestas and others) into one view via ODBC/SCADA integrations.
- 24/7 monitoring so a dropped bearer is dealt with before it becomes a site visit.
Doing it across a whole portfolio
Operators rarely run one site. The real prize is one standard — the same resilient, monitored connectivity design rolled out across every site, feeding a single view of the estate. That's exactly the kind of multi-site rollout we describe in our case studies, and it turns "which sites are up right now?" from a phone-around into a glance at a dashboard.
