Critical Infrastructure
Critical Infrastructure | Generators | Electrical | Mascot
When Mascot’s hospitals, transport hubs and data centres can’t afford even a flicker of downtime, HEP keeps the lights—and lives—on. Our specialised team designs, installs and maintains high-capacity generators that seamlessly bridge the gap between mains power and mission-critical operations. From compact diesel units for rooftop plant rooms to multi-megawatt containerised farms with automatic transfer switching, we deliver turnkey resilience that meets stringent compliance requirements and site-specific constraints.
What sets us apart is proactive service. Real-time remote monitoring flags anomalies before they become failures, while scheduled load-bank testing proves every kilowatt on paper performs in the real world. Paired with 24/7 emergency response, genuine OEM parts and clear, engineer-led reporting, HEP empowers facility managers to focus on their core mission—confident their generators will start first time, every time.
FAQs
Why are standby generators considered critical infrastructure for facilities in Mascot?
Mascot hosts Sydney Airport, data centres, hospitals and logistics hubs that cannot tolerate power interruptions. A correctly-installed standby generator automatically starts within seconds of a grid failure, keeping life-safety systems, security, IT networks and temperature-controlled storage operating until normal supply is restored. Without this redundancy, even a short blackout could cause safety risks, data loss, spoiled inventory or millions of dollars in downtime.
How do I work out the right generator size and configuration for my site?
We begin with a detailed load analysis that captures your peak kVA demand, motor starting currents, future expansion plans and essential vs. non-essential loads. From there we apply a 20-30 % safety margin, choose single or multiple set configurations, and specify the correct alternator, automatic transfer switch (ATS) and fuel capacity. For most commercial premises in Mascot this results in sets ranging from 150 kVA to 1 MVA, but critical data facilities may require paralleled 2 MVA units for N+1 redundancy. Our engineers prepare a full AS/NZS 3000 and AS 3010 compliant design so you can be confident the generator will start, carry and sustain the load every time.
What ongoing maintenance does a generator require to remain compliant and reliable?
• Weekly: visual inspection, fluid-level check and automatic exercise run. • Monthly: battery voltage test, fuel level and coolant concentration check. • Quarterly: load bank test to at least 30 % rated capacity to prevent wet-stacking. • Six-monthly: oil and filter change, belt inspection, exhaust system check, and control panel firmware update. • Annually: comprehensive service in accordance with AS 3786, fuel polishing (diesel only) and infrared thermographic survey of switchgear. We provide 24/7 remote monitoring and keep digital logs for audit purposes, ensuring the set meets insurer, SafeWork NSW and manufacturer requirements.
What Australian standards, council permits or environmental rules apply to generator installations in Mascot?
Installations must comply with AS/NZS 3000 (Wiring Rules), AS 3010 (Electrical installations—Generating sets) and, for fuel systems, AS 1940. Bayside Council requires a Development Application if the unit exceeds 25 kW or is located within 3 m of a boundary, and a noise impact assessment demonstrating compliance with the NSW EPA Industrial Noise Policy. Diesel exhaust after-treatment may be needed to meet NEPC (Diesel NPI) particulate limits, particularly near residential zones. We manage all approvals, acoustic enclosure design and emissions certification for you.
Can a standby generator be integrated with UPS systems, solar PV or building management systems?
Yes. For zero-break power we install a UPS upstream of critical loads; the UPS carries them during the 5-15 second generator start-up window. We can also program the ATS for closed-transition or soft-load transfer to avoid voltage dips. If you have on-site solar, our controllers support droop or ISO-chronous modes so the generator can supplement PV during extended outages or nighttime. All modern sets include Modbus or SNMP interfaces, allowing seamless integration with your existing BMS or SCADA platform for remote status, fuel level and alarm reporting.
How fast can your team respond to an emergency generator fault in Mascot?
Our critical-infrastructure service desk is staffed 24/7 and Mascot is only 10 minutes from our Alexandria depot. A licensed generator technician with spare parts, diagnostic software and a replacement rental set (up to 500 kVA) can be on site within one hour, day or night. Remote monitoring alerts us the moment a fault code is generated, so we often dispatch before you know there is an issue, minimising risk to your operations.
