Industry
Renewables
Support for distributed renewable assets, remote monitoring, supplier platforms, telemetry links, and operational data transfer.
Sector context
Renewable energy assets are often distributed, remotely monitored and highly dependent on vendor platforms. Wind farms, solar farms, battery energy storage systems, inverters, substations, metering systems and SCADA platforms all rely on connected OT.
The cybersecurity challenge is that renewable projects are often deployed quickly, spread across many locations and connected back to central monitoring or third-party support services.
Common OT cybersecurity problems in renewables
Typical issues include
- Distributed sites with limited local staff
- Vendor remote access dependency
- Cloud-connected monitoring platforms
- Inverter, turbine and BESS controller exposure
- Weak asset inventory
- Inconsistent cybersecurity requirements across projects
- Limited segmentation between site OT, monitoring and corporate systems
- Poor handover evidence from EPCs or OEMs
- Unclear responsibility between owner, operator, maintainer and supplier
Relevant services
- Remote access review
- Cybersecurity risk assessment
- Documentation support
- Network segmentation engineering
- Supplier access governance
- Project handover evidence review
Stakeholders involved
Decisions and constraints
- Asset owners need confidence that cyber risk is being managed
- Operators need reliable monitoring and control
- Maintenance teams need remote access that works
- EPCs and OEMs need clear requirements
- Grid stakeholders need resilience
- Investors and insurers need evidence that operational risk is understood
Relevant engineering work
Activities
- OT cybersecurity readiness reviews
- Site connectivity and remote access reviews
- SCADA, inverter, BESS, turbine and substation interface reviews
- Supplier and OEM access governance
- IEC 62443-aligned zoning and conduit support
- Cybersecurity requirements for new renewable projects
- Handover evidence reviews
- Asset visibility and documentation gap assessments
- Practical improvement plans for operating assets
Practical outcome
Decisions the review should support
- Which remote access routes exist
- Who controls supplier access
- Which assets are visible and documented
- Where site networks need stronger separation
- What cybersecurity requirements should be applied to new projects
- What evidence is needed for ownership, operation and assurance
Worked example
- Context
- A renewable energy operator is reviewing remote monitoring connections between site controllers, data platforms and engineering support systems as its site estate grows.
- Review focus
- Meridian can clarify monitoring paths, supplier access responsibilities and the handover evidence needed for reliable operation and assurance.
Worked technical example only; it does not describe a completed Meridian client engagement.
