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.
Examples on this page are fictionalised, generalised or anonymised to show typical problem types without identifying real clients, real sites, real drawings, real systems or confidential project details.
Common OT cybersecurity problems in renewables
- 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
- Remote access review
- Cybersecurity risk assessment
- Documentation support
- Network segmentation engineering
- Supplier access governance
- Project handover evidence review
The common struggle
Renewables environments can have strong engineering performance but inconsistent cybersecurity control. Assets may be managed through OEM portals, remote access tools, cloud monitoring platforms, local substations and third-party maintenance arrangements.
As renewables become more important to grid stability, cybersecurity expectations on these assets are likely to increase. The practical challenge is clarifying responsibilities, data paths and support routes across many sites and suppliers.
Stakeholders involved
Renewables cybersecurity affects owners, operators, investors, EPCs, OEMs, grid stakeholders, maintenance providers and insurers.
- 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
How Meridian can help
Meridian Consultants supports renewables organisations by reviewing cybersecurity risks across distributed OT environments.
The focus is on proportionate risk reduction that works across multiple sites, suppliers and operational models.
- 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
A useful renewables review should help owners and operators understand where distributed OT exposure exists and what evidence is needed.
- 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
Illustrative scenario
Example scenario: A renewable energy operator required a review of remote monitoring connections between site controllers, data platforms, and engineering support systems.
The objective was to clarify remote monitoring paths, supplier access responsibilities and handover evidence needed for reliable operation and assurance.
