POWER & UTILITIES AUTOMATION
PLC, HMI, SCADA, electrical, combustion, balance-of-plant, and remote utility control systems.
RELIABLE CONTROL FROM GENERATION TO DISTRIBUTION
Industrial Systems Integrators designs and integrates automation, electrical, and operational technology systems for power-generation and utility facilities.
ISI connects boilers, burners, generators, pumps, fans, compressors, motors, switchgear, substations, instrumentation, PLCs, HMIs, SCADA systems, and plant data into coordinated control systems.
From an individual equipment upgrade to plantwide modernization, we develop controls around the process, electrical infrastructure, protection schemes, operating requirements, and available outage windows.

Controls are developed around the boiler, burner, equipment-manufacturer requirements, process design, owner standards, and applicable project requirements.
ELECTRICAL DISTRIBUTION AND SUBSTATION CONTROLS
Operators need a clear view of the electrical system without searching through multiple devices and disconnected software platforms.
ISI provides controls for:
- Medium-voltage switchgear
- Low-voltage switchgear
- Circuit-breaker status
- Breaker control interfaces
- Bus-voltage monitoring
- Transformer monitoring
- Protective-relay communications

Protection functions remain coordinated with the project’s independent protective devices, approved protection scheme, and owner requirements.
UTILITY SCADA AND REMOTE TELEMETRY
Utility assets may be distributed across a plant, service territory, or multiple remote locations.
ISI develops SCADA and telemetry systems using:
- Programmable logic controllers
- Remote terminal units
- Protective-relay communications
- Licensed radio systems
- Cellular communications
- Fiber-optic networks
- Industrial Ethernet
- Existing utility networks
- Modbus communications
- DNP3 communications
- OPC interfaces
Centralized systems can provide:
- Generator output
- Breaker and switch status

- Generator and utility-source status
Communication failures and stale data are clearly identified so operators know when remote measurements are unavailable.
ALARMS, HISTORIANS, AND OPERATING DATA
Power and utility operations generate large amounts of process and electrical data. The information must be organized before it becomes useful.
ISI integrates:
- Alarm and event history
- Sequence-of-events data
- Process trends
- Generator output
- Electrical demand
- Voltage and current
- Frequency
- Power factor
- Motor runtimes
- Equipment starts
- Boiler measurements
- Steam conditions
- Fuel consumption
- Water-system data
- Equipment availability
- Communication status
- Historian platforms
- Operating reports
Operators and maintenance personnel can use this information to troubleshoot interruptions, compare operating conditions, and identify recurring equipment problems.
POWER PLANT AND UTILITY MODERNIZATION
Obsolete controllers, unsupported operator interfaces, and undocumented communication networks increase maintenance difficulty and outage risk.
Modernization services can include:
- Existing-system investigation
- PLC replacement
- RTU replacement
- HMI and SCADA migration
