Remote Power System Solutions

The Vendor is required to provide to better understand commercially available, proven hybrid power system solutions capable of serving a remote customer in state following the planned removal of an existing radial distribution line.
- High level functional description
1. Application
• Steady state load on the order of ~80 kw, however interested in solutions ranging from 10 to 100 kw,
• Ability to handle short duration transient loads and cold load pickup following restoration,
• Expandability to higher capacities through modular or parallel operation,
• Capability to operate efficiently during short seasonal peaks while minimising operating cost and intervention during extended off season periods.
2. Other applications considered
• Availability of similar system offerings across a broader size range,
• Scalability or modularity of solutions for systems up to 500 kw sustained peak output,
• Whether expansion requires identical units, modular add-ons, or re-engineering.
• Availability of trailer-mounted configurations for the proposed system or similar offerings, noting that agency primary application is for a containerized, skid-mounted, or otherwise self-contained system suitable for remote deployment
• Ability to integrate larger solar arrays (10 kw+) where supported, including any configuration or interface requirements.
- Controls and communications
• Communication protocols: open protocols support is of value, with specific reference to dnp3 over TCP/IP is the typical agency SCADA protocol.
• Modbus TCP is a second choice of an open protocol.
• Indicate whether a preliminary point list or register map can be provided at this stage.
• Control option via on site agency PLC (programmable logic controller)
• Remote operations: capability for remote enable/disable, load shedding, and parameter adjustment over a satellite link.
• Alarming and event logging: on-board event logging capacity, alarm prioritization, and methods for forwarding alarms to agency SCADA or other notification systems.
• Autonomous operation: system behavior during extended communications outages, including whether the system continues to operate, log events, and self-recover without external connectivity.
• Cybersecurity: supported security features, including encrypted communications and any relevant standards compliance.
• Monitoring platform: whether system monitoring is available locally (on-site HMI or controller), via vendor-hosted cloud platform, or both, and whether agency can access raw operational data.
• Integration experience: examples of prior deployments integrated with utility agency systems, particularly over satellite or other high-latency links.
• Low latency star link is the planned communication option, however, communications may be over other higher latency options.
