That is a standing connection into operations. 02 ### Fleet operations across many sites Remote operations centres run dozens of sites at once. A compromise in the ROC can cascade to every site it manages. 03 ### Grid Code and curtailment control Curtailment, setpoint and Grid Code response commands flow into inverter-based resources from the fleet operations centre. Those commands have to be trustworthy. Utilities - Renewables and BESS > When OEM access, fleet operations and site control share the same paths, every vendor incident becomes a candidate for a fleet-wide outage. The Scenario ### Scenario: OEM portal compromise across a wind fleet Attackers compromise the OEM remote support portal used to monitor a wind fleet. From there they pivot through the persistent VPN into the fleet operations centre and push a malicious firmware payload to turbine controllers across multiple sites. Several sites curtail to zero output for the rest of the day. With Control, OEM access opens only on scheduled, brokered windows. Firmware updates that cross into a site require named, multi-party approval. The fleet operations centre and the per-site SCADA sit on separate fabrics, so a ROC compromise cannot walk straight into every site. Verified baselines for turbine and inverter configuration are held on infrastructure that has no live network path to production and require multi-party authorisation to release. "Our biggest standing connection was never an attacker. It was a vendor. That is the gap to close." Module deployment · renewables and BESS site ## Where each Control module is deployed across wind, solar and battery storage. Renewable generators run a fleet of remote sites with heavy OEM remote access into wind turbines, inverters and battery management. Control puts a real boundary between the office, the OEM zone, the site SCADA and the inverter and battery controllers behind it. Grounded in NIST SP 800-82 Rev. 3, IEC 62443-3-2, IEC 61400-25 and Grid Code requirements for inverter-based resources.

### Sovereign generation data Operational and Grid Code data remains within the agreed jurisdiction in carefully selected Firevault Bunkers. 02 ### Multi-party control Curtailment, setpoint and firmware actions require sign-off from both fleet operations and security teams. 03 ### Regulatory evidence Continuous compliance evidence for NIS2 and Grid Code cyber expectations for inverter-based resources. 04 ### Out-of-band management Cellular and dedicated paths keep the control plane reachable when primary networks are compromised. 05 ### Tamper-proof logging Every access, configuration change and curtailment command lands in immutable logs on physically separate infrastructure. 06 ### Verified configuration baselines Verified baselines of turbine, inverter and BESS configuration enable a known-good restore of control-plane state. Demo to Live ## Adoption Guide Step 1 #### Network assessment Map every path between corporate IT, OEM portals, the fleet operations centre and per-site SCADA to identify standing vendor connections. Step 2 #### Zone architecture design Design physically separated zones aligned to OEM, fleet and per-site boundaries, with Control modules at each one. Step 3 #### Non-production pilot Deploy in a test environment mirroring a single site and the ROC with full zone separation, multi-party authorisation and compliance logging. Step 4 #### Operational deployment Full deployment across the renewables and BESS estate with verified configuration baselines, continuous compliance evidence and 24/7 out-of-band management.
