Defence and secure government sites demand reliable, redundant power and strict compliance. Sydney Power Group provides Level 2 ASP electrical services for these facilities across Greater Sydney, covering network mains, metering and generator supply for standby and backup systems. Any alteration to the network supply must be performed by an accredited Level 2 ASP, which SPG holds across Ausgrid, Endeavour Energy and Essential Energy.
We work methodically, document thoroughly and coordinate access requirements so sensitive operations continue without interruption.
Redundancy and Standby Power
Critical operations cannot afford unplanned outages. We design and connect generator supply, changeover systems and supply upgrades that keep essential loads energised when the network drops. Correct metering and switchboard configuration ensures backup systems engage cleanly.

Secure, Compliant Network Work
From underground mains to smart metering, all network-side work is completed to AS/NZS standards with full compliance paperwork. We coordinate closely with site personnel to meet access, security and scheduling requirements.

Why Choose a Level 2 ASP
Only a Level 2 ASP can legally connect and alter your network supply and metering, and defence sites need that work done right the first time. SPG offers accreditation, discretion and reliability. Call 0466 125 125 or book a free on-site quote to discuss redundancy planning.
