Solar farms, battery systems and generating plants need a controller that makes the whole plant behave as one unit at the grid connection. We engineer and commission these controllers for solar, hybrid and thermal plants.
Power plant controller (PPC)
Active and reactive power set-points at the point of connection
Voltage, power factor and frequency response to the grid code
Ramp-rate limits and curtailment
DEWA D33 requirements and solar grid regulations
Coordination of inverters, batteries and generators
Power management system (PMS)
Synchronisation and load sharing
Load shedding and load management
Island and grid-parallel operation
Interconnection of two or more plants
Hybrid PV, battery and genset control
Turbine and engine controls
GE Mark IV to Mark VIe upgrades
FT100 to FT125 control panel upgrades
Governor, AVR and synchroniser integration
Support for overhauls and performance tests
Technology partner: Inavitas PPC and SCADA
Since 2011 our team has commissioned 14 synchronisation and power management systems, from two-generator island plants to a 60 MW interconnection of six gas turbines.

We install, test and commission low-voltage systems, support medium-voltage work in operating plants, and build control and distribution panels to our own EPLAN designs.

Client approval of drawings
Assembly, wiring and labelling
FAT with the client
Delivery, installation and SAT
Most of our electrical work happens next to equipment that stays in service. We work under the client's permit-to-work, isolate and prove dead before every task, and plan tie-ins with operations.

We support solar and hybrid power projects from design to operation: the electrical balance of plant, the control and monitoring systems, and the connection to generators or the grid.
Solar PV plants
MV and LV installation, terminations and testing
Inverter and transformer station commissioning
Tracker and weather station integration
Plant SCADA, PPC and CCTV
Hybrid plants and storage

CCTV, perimeter protection, access control and the fibre networks behind them, on Bosch, Dahua and Hikvision. We design, supply, install, commission and maintain them as one service.
Every system we deliver starts as a drawing set. We engineer in EPLAN Electric P8 and Pro Panel 3D, AutoCAD Electrical and ETAP, from FEED to as-built.
Many plants run on control systems that are no longer supported. We replace them with current platforms while the plant keeps running, and plan each cutover around the operator's shutdown windows.
How we migrate
Audit of the existing system and its documentation
Logic and graphics conversion with line-by-line checks
Plants already collect large amounts of data in their control systems and historians. We connect that data securely to analytics and AI tools, so operations and maintenance teams can act earlier.
Fieldinstruments, PLC, SCADA, DCS
Edge gatewaydata collection and buffering
OT/IT DMZfirewalls, one-way data flow
Data platformhistorian, on-premise or cloud
AI modelsprediction, detection, optimisation
Actiondashboards, alerts, work orders
Data leaves the control network through a secured DMZ. Control stays with the plant control system unless the operator approves closed-loop optimisation.
Predictive maintenance
Models on vibration, temperature, pressure and run-hour data that flag developing faults in turbines, compressors, pumps and motors.
Anomaly and alarm analytics
Finding abnormal process behaviour, bad actors and alarm floods in historian and SCADA data.
Solar and energy analytics
String, inverter and plant performance tracking, loss and soiling analysis, energy forecasting.
Fleet and dispatch optimisation
IoT telematics with AI-assisted scheduling, as on the airport fuel management system we are delivering.
Computer vision on CCTV
PPE checks, intrusion and perimeter alerts for plants, solar farms and unmanned sites.
Assistants for O&M teams
Search and question answering over manuals, drawings, procedures and maintenance history.
Digital twins
Electrical and process models kept in step with live data for studies, training and what-if analysis.
Live project portals
Web portals that show clients the progress, schedule and documents of their project.
OT cybersecurity to IEC 62443
Network segmentation, secure remote access, hardening of servers and workstations, backup and recovery, and user access control on every connection we make to a control network.
Technology providers
Inavitas for energy and asset performance software, ETAP for electrical digital twins and QuakeLogic for sensor networks. We pick the platform for each client and integrate it with their existing systems.
