Short spikes can set your demand charge

demand charges are based on load, not time
The City of Sydney explains that a demand charge is based on the load your equipment draws, even over a short period, so running machines together pushes it up.

Power Logging
Power logging for factories, warehouses, offices and shops all across Sydney, from Wetherill Park and Kemps Creek to Penrith and the Blue Mountains. We record how your site actually uses power, then show you the overloads, peaks and power quality problems, so you upgrade only what you need.

Power logging
Measure first, then decide what to upgrade
Power logging records how your site actually uses power, phase by phase, over several days. Dann's Electrical logs factories, warehouses, offices and shops across Penrith and greater Sydney.
Before you upgrade a switchboard, apply for more supply or add big equipment, you need to know what your site actually draws. The logger sits on your main board or sub-boards while the site runs as normal.
We show you where the peaks are, which phases are overloaded, and whether there are voltage dips or harmonics damaging equipment. Then we tell you what to fix, and what you can leave alone.

Sound familiar?
When businesses get power logging done
Most people don't search for power logging. They search for the problem. If any of these sound like your site, logging is usually the first step to fixing it.
Why does our power keep tripping?
Tripping at the same time each day, or when certain machines start, often points to an overloaded circuit or unbalanced phases. Logging shows exactly what's running when it trips.
Can our switchboard handle a new machine?
Before you add an oven, cool room, compressor or EV chargers, logging shows how much spare capacity your board and supply really have, so you know if it'll run or needs an upgrade first.
Why has our demand charge gone up?
On a demand tariff, a short spike can set the charge. Logging shows which equipment creates the peak, so you can stagger start-ups instead of paying for it.
Why do the lights flicker when equipment starts?
Lights dimming when motors, compressors or welders start are a sign of voltage dips. Logging records each dip and when it happens, so the cause can be found.
Why does our equipment keep failing?
Harmonics and voltage swings can overheat motors and damage drives, chargers and electronics. Logging measures power quality, so you fix the cause instead of replacing parts.
Do we need a supply upgrade?
A supply upgrade is a big cost. Measured data can support an application to Endeavour Energy, or show the site can cope with balancing or a board upgrade instead.
What's using power when we're closed?
If your bill stays high even when the site is closed, logging shows what's running overnight and on weekends.
Is solar or a battery worth it for our site?
Logging shows when your site uses power through the day, which is the data a solar or battery installer needs to size a system that fits.

Before a supply upgrade
Real data to support (or avoid) an Endeavour Energy application.
Hidden faults
Patterns that point to failing equipment or connections.
Fixes and upgrades
Switchboard, protection and balancing work if it's needed.

Why measure first
How your load affects your bill and your supply
Demand charges and connection rules from the City of Sydney, Endeavour Energy and the NSW Government.
Big loads pay for network works
Your cost
for large load connections
Endeavour Energy says large load and rural customers must pay for any works required to facilitate their connection. Logging first can show whether you really need the upgrade.
Measuring is a cost-effective first step
Cost-effective
way to manage energy use
The NSW Government says metering and monitoring systems are a cost-effective way for NSW businesses to manage and reduce their energy use.
Where we work
Power logging near you
We travel all across Sydney for commercial and industrial work. We look after sites in Wetherill Park, Kemps Creek and the western industrial precincts, as well as Penrith, the Blue Mountains and the Hawkesbury.

How long does power logging take?
Usually 1 to 7 days, so we capture both normal and peak operation. The logger records passively while the site runs as usual.
Will it disrupt my business?
Usually not. Fitting the logger takes a short visit, and it records in the background.
What does power logging show?
Peak demand, circuit and phase loads, voltage dips and harmonics, after-hours usage and how much capacity you have left.
Do I need logging before a supply upgrade?
It's worth doing. Endeavour Energy sets an assessed load for connection applications, and real data on what you actually use can support the application, or show you don't need the upgrade.
Can you fix the problems you find?
Yes, switchboard upgrades, extra protection, phase balancing and supply upgrades, including Level 2 work.
How much will it cost?
Site assessments are free, and our work is fixed price. We give you a fixed price before any work starts, so the price you agree to is the price you pay. There are no hidden fees.
Which areas do you cover?
All across Sydney. We look after sites in Wetherill Park, Kemps Creek and the western industrial precincts, plus Penrith, the Blue Mountains and the Hawkesbury.
