Why Is There No Power After a Storm?

Emergency? Call now

24/7 response across Sydney metro · Licensed Level 2 ASP

Power loss after a Sydney storm stems from Ausgrid or Endeavour Energy network failures, surge-damaged switchboards, or water-damaged outdoor circuits. Flooded switchboards and exposed storm wiring are live electrical hazards; book Sydney Electrical Service or call 0433 462 902 for 24/7 emergency response.

Sydney's storm season runs October to March, with east-coast lows capable of dumping 100 mm of rain and 100 km/h gusts in a single afternoon. Overhead lines come down most often in tree-heavy suburbs like Lane Cove, Wahroonga and Pymble; soaked outdoor circuits are a recurring issue in coastal pockets like Coogee, Maroubra and Cronulla; and surge-damaged switchboards turn up everywhere lightning struck nearby.

What This Fault Means

A storm can break your supply at multiple points:

Overhead network conductors — branches snap them or wind tears them off poles
Service mains to your home — overhead cables ripping away from the point of attachment
Service fuse — surge or short-circuit blowing the network-side fuse in your meter box
Switchboard surge protection — purpose-built to sacrifice itself in a strike
Main switch and breakers — tripping or burning out under fault conditions
Outdoor power circuits — water-saturated outlets, garden lights, pool equipment
Solar PV system — inverters often fault-out under grid disturbance and may not auto-restart

Your power may be out for any combination of these reasons. A licensed electrician's job is to identify which apply to your home and restore safe supply.

Common Causes

A network outage in your suburb — confirmed via Ausgrid (13 13 88) or Endeavour Energy outage maps
A tree branch on overhead consumer mains — common in Wahroonga, Killara, Pymble, Lane Cove, Hunters Hill
The point of attachment torn from the eaves or wall by wind
A blown service fuse from a surge cascading through the installation
A tripped main switch from a downstream fault (water, surge, or burnt outlet)
An RCD that won't reset because outdoor circuits are saturated
Surge-damaged switchboard busbars or breakers
Lightning damage to surge-protection devices, modems, alarms, and air conditioner controls
Solar PV inverter shutdown that has not auto-recovered since the disturbance
Water ingress into a meter box where seals have aged or sealing has failed
Damaged consumer mains where overhead cables sag close to vegetation

Is It Dangerous?

Storm damage is often much more dangerous than it looks. Treat the following as urgent:

Red flags — call immediately if you see any of these:

Sagging or fallen overhead lines — even on private property, treat as live and stay 8 metres clear
A burning smell at the meter box or any outlet
Smoke from the switchboard
Crackling or buzzing at the meter
Shocks or tingles from taps, sinks, or appliances
Wet switchboards or meter boxes
A point of attachment that is loose, broken, or pulled away from the building
Sparks at the overhead service connection
Water visibly inside any outdoor power point or garden light

What to Do Right Now

Stay clear of any fallen lines — your boundary or your roof — until network crews confirm they're isolated.
Check Ausgrid or Endeavour Energy outage maps to see if the issue is network-wide.
If the network is up, look at your switchboard. The main switch may have tripped; do not force it.
Try resetting the main switch once. If it holds, monitor for any returning fault.
If it won't hold or trips immediately, leave it OFF and call us.
Switch off all outdoor circuits before the next downpour, even if they're holding now.
Photograph any visible damage — fallen branches on cables, broken point of attachment, water inside the meter box.
Move sensitive electronics off mains power until surge protection has been verified.
If any appliance smells burnt or behaves erratically post-storm, unplug it immediately.

When You Must Call a Licensed Electrician

Call Sydney Electrical Service on 0433 462 902 if:

The main switch will not stay reset
Your point of attachment is damaged or pulled away from the building
Overhead consumer mains are sagging, broken, or against vegetation
The switchboard or meter box has visible water, smoke, or burning
An RCD trips repeatedly because outdoor circuits are wet
You suspect surge damage — appliances, lights, or modems behaving strangely
The solar PV inverter has not restarted and the system reads faulted
You smell burning anywhere in the house
You feel a tingle from any metalwork (a serious symptom of lost neutral)

We are licensed Level 2 ASP contractors. We can attend, isolate, repair, and re-energise consumer mains, point of attachment, and service-fuse work in a single visit — and coordinate with Ausgrid where network reattachment is required.

Why DIY Is Dangerous and Illegal in NSW

Storm-affected installations are uniquely dangerous because the energised state of cables, switchboards, and outdoor equipment is unpredictable. A line that "looked dead" can re-energise without warning when network crews restore upstream supply. Water inside a switchboard or outdoor enclosure can re-establish a leakage path the moment the breaker is reset.

Under NSW law, all fixed electrical work must be performed by a licensed electrician, and any work on the supply side requires a Level 2 ASP. The *Service and Installation Rules of NSW* are clear on the boundary, and the *Gas and Electricity (Consumer Safety) Act 2017* makes unlicensed work a prosecutable offence. Insurance for storm damage involving unlicensed repair is routinely refused.

If a tree is down on your supply lines, do not attempt to clear it yourself. Stay clear, call 000 if anyone is at risk, then call Ausgrid (13 13 88) and us on 0433 462 902.

Frequently Asked Questions

How can I tell if it's a network outage or a problem with my house?

Look at neighbours and streetlights. If everyone is dark, it's a network outage — call Ausgrid. If only your home is out, it's an installation issue and we can help.

The power came back on but my main switch keeps tripping. Why?

Storms often leave residual moisture or surge damage that doesn't show until power returns. A main switch tripping immediately on re-energise indicates a downstream fault — often water in an outdoor circuit or a damaged appliance.

Did lightning damage my electronics?

Possibly. Indirect lightning strikes induce voltage spikes in nearby cabling, damaging modems, TVs, alarm panels, AC controllers, and oven boards. The damage is often subtle — a device that "kind of works" but is unreliable.

My solar isn't working since the storm. What do I do?

Solar inverters disconnect when grid disturbances exceed their tolerance and most should auto-restart. If yours hasn't, check the inverter display for fault codes and call us. Damaged DC isolators are common after lightning.

Is my point of attachment my responsibility or Ausgrid's?

The point of attachment hardware (the bracket and insulator on your home) is the property owner's responsibility. The service main itself is Ausgrid's. Repairs and replacement are licensed Level 2 ASP work — we handle this routinely.

The switchboard is wet. Is it safe to dry it off?

No. A wet switchboard must be isolated, professionally dried, tested, and re-certified before being put back into service. Do not open it, do not towel it down, and do not reset breakers in a wet board.

Could a tree on my line affect just my house?

Absolutely — particularly in tree-heavy Sydney suburbs. The tree may have hit only your service mains, not the network distribution line. Don't approach the tree. Call us and we will coordinate clearance and reinstatement.

How quickly can you respond after a major storm?

During peak storm response we are running 2–4 hour ETAs across Sydney. We prioritise active fire risk, fallen lines, wet switchboards, and medically dependent customers. Call 0433 462 902 as early as possible to lock in your slot.

Is it safe to use my outdoor power points and garden lights after the storm has passed?

No — treat all outdoor GPOs, garden lighting circuits, and pool equipment as unsafe until an electrician inspects them. Even weatherproof-rated fittings can allow water ingress after Sydney's driving coastal rain, and a hidden fault inside a soaked outlet can deliver a fatal shock the moment you plug something in.

Should I worry if my lights are flickering or running dim since the storm?

Yes — don't ignore it. Persistent flickering or unusually dim lights after a storm often points to a loose or corroded service connection at the meter box, which can arc intermittently and start a fire inside your wall. Get it inspected before the next wet weather event makes it worse.

Can I reset the safety switches myself, or do I really need an electrician?

You can try pressing the reset button on any tripped RCD (safety switch) in your switchboard — if it holds, the fault has likely cleared on its own. If the switch won't reset or flicks straight back off, there is an active fault on the circuit and a licensed electrician needs to find it before you restore power to that part of the house.

How much does it cost to repair storm-damaged wiring or a switchboard?

Cost varies widely depending on whether the job is a single damaged circuit or a full switchboard replacement after flooding. Sydney Electrical Service provides fixed-price quotes with no hidden call-out surprises — phone 0433 462 902 to describe what you're seeing and get a firm price before any work starts.

Who should I call if I see a fallen power line in my street after the storm?

A downed line is a life-safety emergency — keep everyone at least eight metres away and call Ausgrid on 13 13 88 (or Endeavour Energy on 13 22 55) immediately, then 000 if anyone is injured or there is fire. Never touch or drive over a fallen line, even if it looks dead — it can re-energise without warning when the network switches remotely.
